Podcasts about 6v

This week's EYE ON NPI is trendy and buzzy, it's Boréas Technologies' BOS1931 High-Efficiency Piezo Driver (https://www.digikey.com/en/product-highlight/b/boreas/bos1931-high-efficiency-piezo-driver). This chip is a compact way to add powerful high-voltage piezo drive to any product, combining three chips: power supply, waveform generator and driver. With a complete I2C/I3C interface that you can connect to any microcontroller/processor it's the most advanced all-in-one piezo driver we've seen! Piezo (https://en.wikipedia.org/wiki/Piezoelectricity) discs are multi-use devices that convert mechanical movement to electrical signal, and vice-versa. They're most often seen as electrical-to-mechanical converters such as piezo beepers (https://en.wikipedia.org/wiki/Piezoelectric_speaker) where an AC signal, usually 3 to 6V peak-to-peak square wave, is applied across the disk. The frequency of the wave is translated into a sound frequency. It doesn't have the same fidelity as a magnetic speaker but its much thinner, less expensive for the component and driving circuitry, and for 2 to 4 KHz beeps it's just fine. Piezos can also be used the opposite way, where mechanical stress on the crystal is translated into an electrical signal. In this way it can be used as a switch or force sensor (https://en.wikipedia.org/wiki/Piezoelectric_sensor), again usually a few microamperes' worth of current is generated. For these basic uses, your standard microcontroller pin, or at best an H-Bridge will work just fine: you can drive piezo's differentially to get more Vpp across the disc but essentially we're still talking about only a few Volts. There are some times when you want to make a piezo really 'loud' - that is, putting 100+ Volts across the crystal to generate a big mechanical response. This is often not for audible use cases, after all if you wanted to do that you'd just use a magnetic speaker (https://www.adafruit.com/product/1732) that can get to many many Watts of output efficiently. FYI there's two variants of the chip: the BOS1931 (https://www.digikey.com/short/w9tz9tbj) and the BOS1921 (https://www.digikey.com/short/nnb0r29r). The '31 can only do piezo driving. The '21 can do sensing as well as driving, so it can be used for force-feedback products. In this particular EYE ON NPI we'll just be chatting about the driving capabilities of both. So, while we can do basic sensing/beeping with a few Volts - when we want to have significant motion for blasting sonar or moving fluid around we can only increase the movement by increasing the peak-to-peak voltage. Each piezo you buy will have a voltage rating - and you will need a boost converter to generate that peak-to-peak. For the BOS19 series of chips, you can get +-95V so 190Vpp max, which will drive any piezo you find, and you only need 3~5V input thanks to a built-in DC/DC boost converter. Boréas didn't stop there. Not only do you get a booster, but also a full waveform manager with I2C/I3C control. You can can fill up a FIFO buffer with waveform bytes to generate different shapes. There's a sine generator you can control with an envelope creator. Or, you can piece together waveform shapes for different pump/haptic behavior, giving you the customizability of a byte-wise waveform generator with the simplicity of a sine generator. They even have a Haptics Studio' to help you craft the waveform you want (https://www.boreas.ca/pages/haptic-studio). The BOS1931 (https://www.digikey.com/short/w9tz9tbj) and the BOS1921 (https://www.digikey.com/short/nnb0r29r) come in two packages: an easy-to-layout-and-solder QFN and a tiny-and-advanced BGA. Both have the same core so just pick whether you need simplicity or small size. Since its a pretty serious boost converter and driver - the piezo connects directly to the output pins - you'll need to watch your layout. Check the datasheet for their recommended setup to make sure you don't have excessive power loss or EMI. IF you want to get started quickly, the BOS1921-KIT-B01 (https://www.digikey.com/short/v9hn8mcd) evaluation board will let you use their configuration software to quickly determine how your piezo actuator or sensor response to the waveform generator and booster before you start laying out the components on a prototype PCB. If you have some serious piezo-ing you need to get moving, the Boréas Technologies' BOS1931 High-Efficiency Piezo Driver (https://www.digikey.com/short/w9tz9tbj) can do everything from voltage generation, waveform shaping, and differential driving. And best of all it's in stock right now at Digi-Key for immediate shipment! Order today and DigiKey will pick and pack your order in an instant so that you can be vibin' with your fancy new piezo controller by tomorrow afternoon.

Esta semana, vamos a hablar sobre cómo elegir las baterías para nuestras actividades de radioaficionado. Es importante considerar las características y tipos de baterías según nuestras necesidades. Las baterías tienen componentes químicos y cables, y dos aspectos clave son el voltaje y el amperaje. La mayoría de los equipos funcionan con 13.8 voltios, pero pueden tolerar variaciones. El amperaje determina la duración de la operación, pero también aumenta el tamaño y el peso de la batería. Es crucial balancear nuestras necesidades de energía y el peso del equipo. Para calcular la energía necesaria, consideramos nuestro uso y los tipos de batería disponibles. ¿Nos apoyas para que podamos seguir haciendo este podcast y más contenidos?

Prečo je Stodola taká významná osobnosť? Prečo by sme naňho mali byť hrdí? Naozaj dostal meno podľa cisára Marca Aurelia? V knihe sú stretnutia Stodolu s Einsteinom, Štefánikom, Schweitzerom, je tam Lenin, videl Hitlera...je to všetko skutočnosť alebo spisovateľská fabulácia? A čo konkrétne rozhovory s A.Einsteinom o fyzike, teórii relativity ap. Kaviareň Odeon bola už vtedy symbolom intelektuálnych debát. Stodolovci boli veľmi vzdelaná rodina a mali úžasnú domácu knižnicu. Čo v nej bolo? Stodola chcel uľahčiť ranením vojakom návrat z 1.svetovej vojne a zostrojil protézu ruky. Či je to princíp 6V?

This week's EYE ON NPI is going to give you life, we're looking at Nexperia's Battery Life Booster ICs (https://www.digikey.com/en/product-highlight/n/nexperia/battery-life-booster-ics), an interesting solution for dealing with common coin cell batteries as an inexpensive power supply for your small electronic products. The marketing copy for this chip series is pretty eye-catching, with copy that they are "designed to extend the life of a typical lithium coin cell battery by up to an order of magnitude (10x) while also increasing its peak output current capability by up to 25x" (https://www.digikey.com/en/product-highlight/n/nexperia/battery-life-booster-ics) Quite a claim! So let's take a look at what this chip can really do, and why we need it to help with our coin battery-powered designs. Primary Lithium LiMnO2 coin batteries (https://www.digikey.com/en/products/filter/battery-products/batteries-non-rechargeable-primary/lithium-manganese-dioxide/90) are hard to beat when you want ultra-dense, low-cost power that is very small. They are the smallest form factor of user-serviceable battery. And the power density of coins - plus their flat shape - makes them great for wearable devices, medical sensors or hearing aids, wireless nodes, anything that is smaller than a finger. With a nominal voltage of 3VDC, and 280 Wh/kg density, they are more dense than a AA alkaline. LiSOCl2 batteries (https://www.digikey.com/en/products/filter/battery-products/batteries-non-rechargeable-primary/lithium-thionyl-chloride/90?s=N4IgjCBcoCxgTFUBjKAzAhgGwM4FMAaEAeygG0QBmANgFZKEQBdIgBwBcoQBldgJwCWAOwDmIAL6SgA) are even more dense, with 3.6V nominal and 500 Wh/kg - twice the density of LiMnO2 or Alkaline. Both are non-rechargeable batteries, and while fairly inexpensive when bought in bulk, they can add up in cost when buying from a grocery store, so making sure that they last a long time is essential for a good customer experience. The Energizer Lithium Coin Handbook and Application Manual (https://data.energizer.com/pdfs/lithiumcoin_appman.pdf) is chock full of good advice for folks who want to use a CR2032 or similar coin battery to power their products. It's written with engineers in mind, so a lot of the document covers how the nominal voltage and current, 3V and 240mAh, are deeply affected by shelf life, internal resistance, temperature, and pulse effects. The biggest downside you will see on coin batteries is their relatively high internal resistance - IR. Whereas alkaline and LiPoly batteries have internal resistance well below 1 ohm, the IR of a CR2032 is 9 ohms. So say you want to draw 100mA from a CR2032, even if just for a few millisecs - that 0.1 A turns into a .9V drop across the IR which means what you thought was a 3V power supply is now 2V - too low for your microcontroller or radio to run. Since the power lost across the IR is 2*I*R and R is fixed, it's doubly important that you keep that I low, so that you can minimize IR loss and use as much of that 700mWh stored energy. In our 100mA example, 30% of the battery energy is lost to resistor heat dissipation! That's where Nexperia's Battery Life Booster ICs (https://www.digikey.com/en/product-highlight/n/nexperia/battery-life-booster-ics) come in. They are designed to be used with products that don't need continuous battery drain, that is they have a very low duty cycle where the user presses a button a few times a day or maybe the sensor node transmits only once a minute. During that short transmit or usage cycle, a radio or LCD display may need up to 200mA but its for a very small amount of time and the voltage needs to be stable. The NBM family of chips do this by slowly sipping a small amount of current from the battery, keeping that I low so that the 2*I*R power loss is minimized, then use that constant current to boost a voltage onto a large storage capacitor. The capacitor is chosen to have high capacitance and high voltage for a large total Joule storage capacity. All four variants of the Nexperia NBM family, NBM7100A (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NBM7100ABQX/19109915), NBM5100A (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NBM5100ABQX/19109703), NBM7100B (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NBM7100BBQX/19110140) and NBM5100B (https://www.digikey.com/en/products/detail/nexperia-usa-inc/NBM5100BBQX/19109874) are in stock right now at DigiKey for immediate shipment! Order today to pick up these chips that will pay for themselves in one battery life-cycle by adding a PMIC to your coin-battery powered products, and DigiKey will ship your chips immediately so you can start integrating them by tomorrow afternoon.

The Great Search - Single Channel 3V to 5V level shifter https://www.digikey.com/en/products/detail/diodes-incorporated/74AHCT1G126SE-7/2711993 On our new Prop-Maker Feather we like to do a 'favor' to our users by level shifting the NeoPixel signal from 3.3V to 5V. We don't always need this but some NeoPixel chipsets are a little finicky about the levels, especially if you have a 5.5V or 6V power line on the NeoPixels. We'll use a single buffer, and it needs to be small, so we'd like a tiny package. We'll also review the 74 series logic family (https://en.wikipedia.org/wiki/7400-series_integrated_circuits) to verify what series we want to filter out when we search on DigiKey for this part.

Alfa Romeo ha fabricado excelentes coupés y deportivos, pero creo que su especialidad han sido las berlinas deportivas. Han fabricado muchas y muy buenas, pero creo que el 75 es, sino la mejor, una de las mejores… y en cambio es un modelo que no se ha valorado, en mi opinión, como se merece… Y os recuerdo una cosa: ¡Es el último modelo cien por cien Alfa! Pero antes insisto en esto: El 75 aparecido en 1985 fue el último modelo de Alfa diseñado y producido antes de su adquisición por parte de Fiat. Para mí sólo por esto tiene un gran valor. Este coche tiene muchas razones para ser un CLÁSICO con mayúsculas y vamos a verlas todas. Porque insisto, este coche no ha sido valorado como se merece… pero… ¡para eso está Garaje Hermético! Vamos a ver argumentos que convierten a este 75 en un coche notable: Primero: Es el heredero de la excelente plataforma del “proyecto 116” o sea, del Alfetta, con cambio posterior, excelente reparto de pesos y eje trasero de Dion… Segundo: El diseño de la carrocería es obra del propio Alfa Romeo Centro Stile, en esos momentos con el genial Ermanno Cressoni al frente. Tercero: Ha montado muchos tipos de motores, pero hay que destacar el excelente 2.0 litros “Twin Spark” de doble bujía, el peculiar Turbo y el excepcional V6 tipo Busso… sin olvidar potentes turbodiésel. Cuarto: Pocas berlinas conozco que sean tan divertidas de conducir… aunque su conducción, lo advierto, no está al alcance de cualquiera… aquí no hay ayudas electrónicas y el cambio, hay que saber manejarlo. Quinta: Esta es puramente personal y es que conozco este coche a fondo he probado todas y cada una de sus versiones y la verdad, podría contaros decenas de cosas de este coche sin mirar el guion… En este podcast contamos cómo es y como iba este coche. Porque los he probado todos, pero “a tal señor tal honor” y vamos a comenzar por el que en España y en otros mercados europeos se llamó “V6 América” … ¡hasta el nombre el bonito! Este motor es, sencillamente, excepcional. Es robusto, suave, gasta poco, ofrece buena potencia, tiene una excelente curva de par y, sinceramente, conozco pocos motores que suenen tan bien y con una musicalidad como tiene este motor. El genial Giuseppe Busso inventó un sistema de contrapesos que se denominó Flying Arms que conseguían en un V6 a 60 grados una suavidad equivalente a la de un V12. Probé este coche, cuya denominación oficial y lo que ponía en su carrocería era “75 6V 3.0” y no V6. Era la versión de 188 CV que ofrecía una progresividad increíble y potencia de la buena a cualquier régimen… lo que te permitía ahorrarte algún cambio, porque ya hablaremos del cambio… Los Alfa 75 de 4 cilindros no tenían ese sonido ni esa potencia, pero lo compensaban con un mayor equilibro, gracias a la ligereza de su motor. El dos litros de doble encendido denominado “Twin Spark” ofrecía y conseguía 148 CV, que eran muchos para la época y lo siguen siendo en un motor de 8 válvulas… Para mi era mejor que el turbo. El Turbo ofrecía y también conseguía 155 CV. Insisto en esta frase de “ofrecía y conseguía” porque hay leyendas urbanas que decían que estos modelos prometían potencias que no eran reales… ¡falso! Pero la curva de par del 1.8 Turbo era una montaña rusa… hasta las 3.000 rpm. no había “nada”, algo más de 70 CV… pero en solo 1.000 rpm se pasaba al doble, 140 CV un turbo de la vieja escuela que, para sacarle partido, había que hacer uso del cambio y… Lo mejor de estos coches era que su precio resultaba muy competitivo respecto a sus rivales… que no eran muchos, la verdad. Los más claros eran los BMW Serie 3 E30, pero eran mucho más caros y más delicados de conducir. ¿Qué estaban mejor acabados? Sin duda, pero los BMW de la era “pre-electrónica” eran más delicados y menos previsibles que los Alfa Romeo. En este el motor tenía mucho que ver porque los 6 cilindros de BMW, ya sea en 2.0 o en 2.5 litros no eran tan potentes como los de Alfa, pero sobre todo eran mucho menos elásticos… la combinación de un motor que necesitaba ir alto de vueltas con un coche de propulsión trasera sin ayudas electrónicas no era fácil… si alguien lo ha llevado, te lo dirá y si llueve… ni te cuento. Tuve oportunidad, muchas veces, de comprobarlo. En este sentido, como sigo, el 75 era un coche más fácil y predecible. Y como digo, ¡mucho más barato! Los coches verdaderamente bonitos lo son si miras de frente, si miras de perfil o si miras la parte posterior. Confieso que me parece precioso lo mires por donde lo mires, pero lo más bonito no se ve… el bastidor. Porque en 1976 Porsche, como decía mi madre, “inventa la pólvora” y lanza a los cuatro vientos notas de prensa con su inventó, el sistema “transaxle”… pero Alfa Romeo llevaba con esa configuración, con el cambio sobre el eje trasero, desde… ¡los años ’50! Y además del cambio en el eje trasero, estos Alfa del “Proyecto 116” contaban con la peculiar suspensión de eje De Dion con paralelogramo “De Watt” … que explicamos en el vídeo. Bueno no os he contado todo, pero si lo bastante como para que conozcáis y apreciéis un coche tan especial como es el Alfa 75. Pero hay que hablar del cambio, porque no era un mal cambio… si el coche estaba bien mantenido. Ya sabéis que iba atrás y, por tanto, pera manejarlo, se necesitaban unos largos reenvíos. Otros coches con esta configuración, como los citados BMW o nuestros queridos Seat 124/1430, el cambio iba justo debajo de la palanca, sin necesidad de reenvío alguno y eran muy directos… En el Alfa 75 los recorridos eran largos y, sobre todo, había que marcarlos bien. Si lo hacías así, podías cambiar rápido y sin problemas… Pero cuando las gomas sobre las que articulaban estos reenvíos se daban de si, el cambio era un infierno… era necesario cambiarlos. Si compras un Alfa Romeo 75, ¡sobre todo si es un Turbo!, te aconsejo hacer esta operación que ni es cara ni es complicada y el coche es otro. En resumen, un puro Alfa… de hecho, para muchos, el último coche cien por cien Alfa… Aunque para alegría de los aficionados, parece que Alfa, como dice la frase, “ha vuelto por dónde solía”.

Primeira Leitura: Deuteronômio 4,1.5-9 Leitura do livro do Deuteronômio – Moisés falou ao povo, dizendo: 1“Agora, Israel, ouve as leis e os decretos que eu vos ensino a cumprir, para que, fazendo-o, vivais e entreis na posse da Terra Prometida que o Senhor Deus de vossos pais vos vai dar. 5Eis que vos ensinei leis e decretos conforme o Senhor meu Deus me ordenou, para que os pratiqueis na terra em que ides entrar e da qual tomareis posse. 6Vós os guardareis, pois, e os poreis em prática, porque neles está vossa sabedoria e inteligência perante os povos, para que, ouvindo todas estas leis, digam: ‘Na verdade, é sábia e inteligente esta grande nação!' 7Pois qual é a grande nação cujos deuses lhe são tão próximos como o Senhor nosso Deus, sempre que o invocamos? 8E que nação haverá tão grande que tenha leis e decretos tão justos, como esta lei que hoje vos ponho diante dos olhos? 9Mas toma cuidado! Procura com grande zelo não te esqueceres de tudo o que viste com os próprios olhos e nada deixes escapar do teu coração por todos os dias de tua vida; antes, ensina-o a teus filhos e netos”. – Palavra do Senhor. Salmo Responsorial: 147(147B) Glorifica o Senhor, Jerusalém! 1. Glorifica o Senhor, Jerusalém! / Ó Sião, canta louvores ao teu Deus! / Pois reforçou com segurança as tuas portas / e os teus filhos em teu seio abençoou. – R. 2. Ele envia suas ordens para a terra, / e a palavra que ele diz corre veloz. / Ele faz cair a neve como lã / e espalha a geada como cinza. – R. 3. Anuncia a Jacó sua palavra, / seus preceitos e suas leis a Israel. / Nenhum povo recebeu tanto carinho, / a nenhum outro revelou os seus preceitos. – R. Evangelho: Mateus 5,17-19 Glória a Cristo, Palavra eterna do Pai, que é amor! Senhor, tuas palavras são espírito, são vida; / só tu tens palavras de vida eterna! (Jo 6,63.68) – R. Proclamação do Evangelho de Jesus Cristo segundo Mateus – Naquele tempo, disse Jesus aos seus discípulos: 17“Não penseis que vim abolir a Lei e os Profetas. Não vim para abolir, mas para dar-lhes pleno cumprimento. 18Em verdade eu vos digo, antes que o céu e a terra deixem de existir, nem uma só letra ou vírgula serão tiradas da Lei, sem que tudo se cumpra. 19Portanto, quem desobedecer a um só desses mandamentos, por menor que seja, e ensinar os outros a fazerem o mesmo será considerado o menor no Reino dos Céus. Porém quem os praticar e ensinar será considerado grande no Reino dos Céus”. – Palavra da salvação.

Primeira Leitura: 1 Coríntios 5,1-8 Leitura da primeira carta de São Paulo aos Coríntios – Irmãos, 1é voz geral que está acontecendo, entre vós, um caso de imoralidade; e de imoralidade tal, que nem entre os pagãos costuma acontecer: um dentre vós está convivendo com a própria madrasta. 2No entanto, estais inchados de orgulho, ao invés de vestirdes luto, a fim de que fosse tirado do meio de vós aquele que assim procede? 3Pois bem, embora ausente de corpo, mas presente em espírito, eu julguei, como se estivesse aí entre vós, esse tal que tem procedido assim: 4em nome do Senhor Jesus – estando vós e eu espiritualmente reunidos com o poder do Senhor nosso, Jesus -, 5entregamos tal homem a satanás, para a ruína da carne, a fim de que o espírito seja salvo, no dia do Senhor. 6Vós vos gloriais sem razão! Acaso ignorais que um pouco de fermento leveda a massa toda? 7Lançai fora o fermento velho, para que sejais uma massa nova, já que deveis ser sem fermento. Pois o nosso cordeiro pascal, Cristo, já está imolado. 8Assim, celebremos a festa não com velho fermento nem com fermento de maldade ou de perversidade, mas com os pães ázimos de pureza e de verdade. – Palavra do Senhor. Salmo Responsorial: 5 Na vossa justiça guiai-me, Senhor! 1. Não sois um Deus a quem agrade a iniquidade, / não pode o mau morar convosco; / nem os ímpios poderão permanecer / perante os vossos olhos. – R. 2. Detestais o que pratica a iniquidade / e destruís o mentiroso. / Ó Senhor, abominais o sanguinário, / o perverso e enganador. – R. 3. Mas exulte de alegria todo aquele / que em vós se refugia; / sob a vossa proteção se regozijem / os que amam vosso nome! – R. Evangelho: Lucas 6,6-11 Aleluia, aleluia, aleluia. Minhas ovelhas escutam minha voz, / eu as conheço, e elas me seguem (Jo 10,27). – R. Proclamação do Evangelho de Jesus Cristo segundo Lucas – Aconteceu, num dia de sábado, 6que Jesus entrou na sinagoga e começou a ensinar. Aí havia um homem cuja mão direita era seca. 7Os mestres da Lei e os fariseus o observavam, para verem se Jesus iria curá-lo em dia de sábado e assim encontrarem motivo para acusá-lo. 8Jesus, porém, conhecendo seus pensamentos, disse ao homem da mão seca: “Levanta-te e fica aqui no meio”. Ele se levantou e ficou de pé. 9Disse-lhes Jesus: “Eu vos pergunto, o que é permitido fazer no sábado: o bem ou o mal, salvar uma vida ou deixar que se perca?” 10Então Jesus olhou para todos os que estavam ao seu redor e disse ao homem: “Estende a tua mão”. O homem assim o fez e sua mão ficou curada. 11Eles ficaram com muita raiva e começaram a discutir entre si sobre o que poderiam fazer contra Jesus. – Palavra da salvação.

This week's EYE ON NPI is right on time with the MAX31329 Low Current Real-Time Clock RTC (https://www.digikey.com/en/product-highlight/a/analog-devices/max31329-low-current-real-time-clock), which will fit wonderfully into your power, board size and materials budget no matter how small. We are digging this fully-integrated RTC, with a lot of li'l extras that make it an excellent choice for compact products. A Real Time Clock a.k.a. RTC (https://en.wikipedia.org/wiki/Real-time_clock) is a specialty chip that is designed to be ultra low power, so even when everything else in the circuit is turned off, it can still sip power from a super capacitor or tiny battery and keep track of time. It's how your computer and devices can go all the way down to 0% power and yet still know what time it is when recharged/re-powered. Note this is different than storage memory because details like your WiFi password don't need updating every second whereas an RTC has to keep ticking second after second until main power comes back up. Just about everything you own has an RTC in it because timekeeping is so essential to functionality. There are some chips that have built in RTCs but often these are just counters and are not as low power as a true RTC chip. The MAX31329 for example, has a "240nA Timekeeping Current", whereas only the most power-optimized microcontrollers can get below 1uA. Compare it to the DS1307 which has twice the current, ~500nA! With such low currents, you can even use a super cap (https://www.digikey.com/en/products/detail/elna-america/DSK-3R3H703T414-HRL/2171199) instead of a lithium battery to keep time, meaning no special shipping management or battery replacements. Wondering how big a capacitor you'd need? Maxim's got ya covered with their handy super-cap calculator (https://www.maximintegrated.com/en/design/design-tools/calculators/product-design-calculators/supercap.html) OK, so it's low power. What else is so great about it? We also really like that the crystal is in-package integrated! Every RTC needs a crystal oscillator, the thing that actually does the counting of time. The crystals are almost always 32.768KHz crystals (https://www.digikey.com/en/products/detail/abracon-llc/ABS25-32-768KHZ-T/675361?s=N4IgTCBcDaIIYCMBOcDGB7AdgAgIICEBlMAVgFoBmMAOgHYA2ADgGkAJALTIBUQBdAXyA) so the chips count the vibrations into a 16-bit counter. When the counter overflows, a second has passed. Often the crystal is the same size as the chip, or if it's integrated, the chip is pretty large. like in the case of the DS3231.(https://www.adafruit.com/product/3013) In this case, we keep the nice smol size. A nice side effect of having a crystal integrated is improved tuning! Having a precise crystal, say +-5ppm like the Citizen CM315D32768 (https://www.digikey.com/en/products/detail/citizen-finedevice-co-ltd/CM315D32768HZFT/5970266) adds another 50 cents to the bill of materials. Not needed here, it's inside and tuned to that fancy 5ppm. Ideally they'd have a temperature-compensated version in the future, since that can get the precision down to 2ppm but 5ppm is still four times better than most low cost 32khz crystals. Finally, a few small but kind details we caught in the datasheet (https://www.maximintegrated.com/en/products/analog/MAX31329.html): the RTC is 1.6V thru 5V logic friendly, so you can use it with any kit you've got. There's 64 bytes of battery-backed SRAM. I2C has a timeout feature in case of I2C bus jitters which happen at low power dips. Automatic power-switchover to battery when main power droops. Trickle charging with built-in diode and various internal resistors. External clock source select, such as GPS 1pps or line power 50/60hz. This is a nice RTC, at a nice price, and you can book your order for the Maxim MAX31329 at Digi-Key right now (https://www.digikey.com/short/vqrcfdw3) for shipment the moment they come in stock. According to the lead time estimates, this part will be shipping in about 3 weeks / mid-June so you can start designing it into your PCB and chips will come in right when the prototype PCB is complete. While you're waiting you can also pick up one of the MAX31329 shield evaluation boards (https://www.digikey.com/short/ztdw8wfj) which can be plugged into any Arduino-Uno-like microcontroller and also comes with a development board if you just want to use the built in firmware/software.

To get this nifty Spaceball user interface working, we're using a USB to RS-232 adapter cable. But for the next step in this project we'll want to use a Feather board. In order to connect to the DE-9 port safely, we need to convert the TTL serial on a Feather (0-3V logic) to +-6~10V inverted logic. Thankfully, there are chips that make it easy - they even have built in switched-cap converters to create the +6V and -6V logic rails! Let's find one that we can use to make an adapter FeatherWing with.

Mr Ladyada gave me this funky 3D mouse to play with today - it has a DE-9 plus power supply cable on it, so with a little googling and pySerial hacking we were able to get button and motion data out of it. Next up, we want to design a RS-232 Featherwing to make it easy to attach to these sorts of devices and send/receive data. Even though RS-232 is kinda old at this point, we still see a lot of devices that show up with one of these 'universal' ports! We'll also check out a cute Arduino compatible we got in the mail.

Primeira Leitura: Deuteronômio 4,1.5-9 Leitura do livro do Deuteronômio – Moisés falou ao povo, dizendo: 1“Agora, Israel, ouve as leis e os decretos que eu vos ensino a cumprir, para que, fazendo-o, vivais e entreis na posse da terra prometida que o Senhor Deus de vossos pais vos vai dar. 5Eis que vos ensinei leis e decretos conforme o Senhor meu Deus me ordenou, para que os pratiqueis na terra em que ides entrar e da qual tomareis posse. 6Vós os guardareis, pois, e os poreis em prática, porque neles está vossa sabedoria e inteligência perante os povos, para que, ouvindo todas estas leis, digam: ‘Na verdade, é sábia e inteligente esta grande nação!' 7Pois qual é a grande nação cujos deuses lhe são tão próximos como o Senhor nosso Deus, sempre que o invocamos? 8E que nação haverá tão grande que tenha leis e decretos tão justos, como esta lei que hoje vos ponho diante dos olhos? 9Mas toma cuidado! Procura com grande zelo não te esqueceres de tudo o que viste com os próprios olhos e nada deixes escapar do teu coração por todos os dias de tua vida; antes, ensina-o a teus filhos e netos”. – Palavra do Senhor. Salmo Responsorial: 147(147B) Glorifica o Senhor, Jerusalém! 1. Glorifica o Senhor, Jerusalém! / Ó Sião, canta louvores ao teu Deus! / Pois reforçou com segurança as tuas portas / e os teus filhos em teu seio abençoou. – R. 2. Ele envia suas ordens para a terra, / e a palavra que ele diz corre veloz. / Ele faz cair a neve como lã / e espalha a geada como cinza. – R. 3. Anuncia a Jacó sua palavra, / seus preceitos e suas leis a Israel. / Nenhum povo recebeu tanto carinho, / a nenhum outro revelou os seus preceitos. – R. Evangelho: Mateus 5,17-19 Glória a Cristo, Palavra eterna do Pai, que é amor! Senhor, tuas palavras são espírito, são vida; / só tu tens palavras de vida eterna! (Jo 6,63.68) – R. Proclamação do Evangelho de Jesus Cristo segundo Mateus – Naquele tempo, disse Jesus aos seus discípulos: 17“Não penseis que vim abolir a Lei e os Profetas. Não vim para abolir, mas para dar-lhes pleno cumprimento. 18Em verdade eu vos digo, antes que o céu e a terra deixem de existir, nem uma só letra ou vírgula serão tiradas da Lei, sem que tudo se cumpra. 19Portanto, quem desobedecer a um só desses mandamentos, por menor que seja, e ensinar os outros a fazerem o mesmo será considerado o menor no Reino dos céus. Porém quem os praticar e ensinar será considerado grande no Reino dos céus”. – Palavra da salvação.

This week's EYE ON NPI is from a supplier that will challenge your expectations! It's Challenge Electronics' IP68/IP65 Waterproof Battery Holders (https://www.digikey.com/en/product-highlight/c/challenge-electronics/ip68-ip65-waterproof-battery-holders) A series of durable, waterproof battery cases that will do great at powering your board even in intense dusty and wet conditions! Challenge Electronics' IP-rated battery holders provide a low-profile form factor with a watertight seal. Designed for AA and AAA batteries, these holders feature a sleek and easy-to-integrate design ensuring waterproof mounting under the harshest environments to save time in the design cycle. A lot of electronic devices these days are designed to be sealed plastic enclosures (https://www.ifixit.com/smartphone-repairability) - and if they are battery powered, the battery is a LiPoly that is tucked inside and recharged. But there's a lot to be said for the common AA and AAA batteries. These are available anywhere around the world, instantly recognizable, and come in various temperature grades and recharability. For user-or-field replacement, or in use of extreme temperatures, they've still got a place in product design. The down-side is that battery cases (https://www.adafruit.com/product/4779) are often plastic-retained clips that allow dust, humidity, and spilled-diet-coke in, which can cause icky corrosion to the steel or tin terminals. This Flickr image (https://www.flickr.com/photos/sometoast/3242192055) shows a similar self-corroding affect, but having dampness won't help! Challenge's battery holders are compact, but have 4 screws for secure closure and a built-in gasket that will get you IP65-level sealing (https://en.wikipedia.org/wiki/IP_Code). That means fully dust-tight and water-proof to jets of water. Note this doesn't mean you can dunk it underwater - for that you'd need IP67 or IP68 - these are better for outdoor use or in some industrial settings where there may be liquids flying around. Challenge Electronics makes Waterproof Battery Holders (https://www.digikey.com/short/8nw43fr8) in three varieties, with AA and AAA sizes. All have the same IP65 rating. If we had to pick one, the 3xAA will give you a good 2500-4000mAh and 3.6V to 4.5V nominal, great for powering a 3.3V LDO project, and AA's are the most common battery. All three types are available right now at Digi-Key for immediate shipment. Book and order today and it will ship immediately so you can have it in your hand tomorrow afternoon.

This week's EYE ON NPI is so flexible, it's thinking of joining the Rockettes (https://www.rockettes.com/christmas/)! It's TDK's BCS Series Low Illumination Film Solar Cells that are designed for direct integration of products, particularly wearables or credit card size and thickness electronic components. This amorphous panel comes with 6 cells, each about 0.4V open-circuit, for a total of about 2.6V output and 30mA. The nifty part about this panel is just how incredibly thin it is - only 0.2mm which means it can be bonded onto almost any surface or device. And unlike most panels that are made of monocrystalline cells, it is ultra flexible and will not crack or break. TDK's BCS series are thin, lightweight, and flexible solar cells offering high power generation efficiency under fluorescent and LED light sources. The cells are made of amorphous silicon film substrate, and designs can be customized according to various shapes and applications. Because BCS series solar cells offer output stability in low and dim light, they are suitable for use in products used indoors. Additional benefits of solar cells include cost reduction in electrical wiring and battery replacement. When used in combination with a primary battery, solar cells can extend battery life and usage time of rechargeable devices. BCS series solar cells can be used in applications such as watches, wearables, beacons, wireless sensor nodes and other IoT power supply applications, smart cards and locks, and more. Compared to many other ultra-low power source harvesting techniques (https://en.wikipedia.org/wiki/Energy_harvesting) like vibration/piezoelectric or heat, solar is very efficient, very small and very easy to use. Amorphous cells are a great option for folks who want to have indoor-powered electronics without hassle. Simply connect the two terminals to you circuitry plus and minus: when there's ambient light, you'll get voltage output. These panels may look familiar if you've ever had a solar-powered calculator (https://en.wikipedia.org/wiki/Solar-powered_calculator) - often times you'd have to hold these up to a lamp to get them 'kick-started'. Those pocket calculators with LCDs are a great example of ultra-low current draw electronics that could run off of a tiny cell, we're talking under a milliamp here. That's something to keep in mind when integrating panels, they produce about 1/10th of the power folks think they do! The biggest challenge that folks have with implementing solar panels is that they don't really act like a true voltage source or current source: they're somewhere in the middle, like a negative diode. With solar panels, the voltage and current vary constantly depending on sunlight available. They are unstable! That instability confuses electronics battery chargers, which causes them to do one of two things: rapidly turn on and off as they try to draw more current from the panel than possible and/or draw much less current than they can, to keep the voltage from collapsing. So you've got a few choices for implementing this panel: 1) have electronics that is OK with a widely varying input voltage: about 2V to 5V max, and will brownout safely when light disappears all of a sudden. Then, make sure it uses less than a few mA of current so that it doesn't collapse the IV curve by drawing too much power 2) use a super capacitor or rechargeable battery of some sort, that is trickle charged by the panel. once the voltage on the cap gets to a certain amount, the circuitry can use that to perform whatever calculators or data transfer required. 3) use a smart energy-harvesting chip like the LTC3588 (https://www.digikey.com/en/products/detail/analog-devices-inc/LTC3588EMSE-1-TRPBF/2216345) to manage the load on the panel and either charge a battery or directly power electronics with a cleaner supply than directly powered from the solar cell. Sometimes these chips can even operate as a MPPT charger (https://en.wikipedia.org/wiki/Maximum_power_point_tracking) to get the very max power possible. If you're interested in adding a super-flexible and ultra-thin green power supply to your next design, check out the BCS4430B6 (https://www.digikey.com/short/vwm3z35j) and friends. The TDK BCS Series Low Illumination Film Solar Cells (https://www.digikey.com/short/vwm3z35j) are in stock right now at Digi-Key for immediate shipping! Order now and you will be relaxing in the sun by tomorrow afternoon. See these at Digi-Key at https://www.digikey.com/short/vwm3z35j

Son muchos los aficionados que relacionan los motores de 2 tiempos con motos de campo. Y es cierto que en el off road dominaron durante décadas. Pero también es cierto que hubo motos de 2 tiempos que asfalto que se han convertido en míticas. Las motos de asfalto de 2 tiempos era muy, pero que muy divertidas. No están todas las que son, pero sí son todas las que están. Y ya no hay. Bueno, gracias sobre todo a KTM y a sus 2 tiempos de inyección no han desaparecido del off road, pero del asfalto, en muchos mercados, han desaparecido por completo. Me ha costado mucho dejar esta lista en solo 10… incluso he dejado fuera una moto que adoro, la DKW Wankel, que no es 2T… o si, según se mire. Retomaremos el tema. Vamos ya con nuestras elegidas. Kawasaki 750H2 Mach IV (1971) No alcanzaba 4 veces la velocidad del sonido, pero … ¡Cómo corría esta moto! Daros cuenta que estamos en 1971 y en esa época 74 CV y más 200 km/h eran mucho, pero mucho mucho. Suzuki GT 750 (1971) Esta moto competía con la Kawa H2 pero con una ventaja: Teñía refrigeración liquida. Como resulta evidente al ver el enorme radiador que tiene delante, pero en esa época, se podía presumir de tener radiador. El motor ofrecía 67 CV a solo 6.500 rpm, pero era de una finura y progresividad exquisitas, muy Suzuki, se comparaba a un 6 cilindros 4 tiempos. Derbi 2002 (1976) Estoy enamorado de esta moto… Tengo dos buenas razones: Fue mi primera moto “de verdad” y… ¡tengo una! La mía es la segunda versión, denominada 2002 6V. Podría hacer un vídeo solo de anécdotas de esta moto. Fue un amor a primera vista. OSSA Yankee 500 (1976) Lo confieso… ¡Adoro esta moto! De estas 10 me la quedaría y mira que hay motos chulas. Y eso que era una moto complicada, delicada, hasta peligrosa… Pero como sensaciones, hay poca igual. Esta moto nace como un proyecto conjunto entre la marca y el importador americano en USA, John Taylor, pues como sabéis el mercado más importante para las marcas españolas era el de los USA. Bultaco Streaker (1977) Muchos consideran a esta moto como el último éxito de Bultaco. Puede ser cierto, porque en esos años el futuro de Bultaco era incierto, pero esta moto fue un éxito. Su chasis pintado en oro con un tubo refuerzo directo desde la pipa al eje del basculante, era precioso. En general toda la moto estaba decorada en negro y oro con la única excepción del silencioso. Montesa Crono 350 (1981) La última moto de carretera de Montesa con la salvedad de la reedición de la Impala en 1983 Montesa participaba en competición con una 350 2T, como se decía entonces, “de agua” o sea, de refrigeración liquida. Así que cuando en 1980 se presentó esta moto, pues hubo una decepción. Yamaha RD 350 (1983) Un verdadero icono y una moto venerada incluso hoy día. Y una moto que a diferencia de otras de esta lista, si se vendió en España. Pero es que la RD tenía argumentos para ser un icono. Era muy refinada para la época, muy potente, con 60 CV, ligera con unos 140 Kg y con componentes de calidad. Y rozaba los 190 km/h. Y no se rompía. Honda NS400R (1985) Casi una moto de carreras para ir por la calle. Porque la NS400R conservaba el extraño motor tricilindrico de la moto de 500. Un motor que tiene su gracia, porque dos cilindros van muy juntos en paralelo y horizontales, mientras que el tercero va en medio y vertical, dando lugar a un motor muy compacto. Cagiva Freccia C9 (1987) Estéticamente esta moto llamaba la atención, pues era una versión reducida de la Ducati Paso. ¿Es bonita? Pues no me atrevo a pronunciarme, pero no pasaba desapercibida. Y además, corría de verdad. Su motorcito de 125 daba 27 CV a 10.000 rpm y raspaba los 160 km/h gracias a su cuidada aerodinámica. Aprilia AF1 Futura (1991) Las Aprilia triunfaban en las carreras y la marca lanzó un modelo con el objetivo de seducir a los jóvenes que querían emular a sus pilotos favoritos. Como iba dirigida a un público joven esta moto era una 125… pero no te engañes, conseguía casi 30 CV y pesaba poco más de 100 kg… o sea, que corría de verdad. Como os decía, algunas se han quedado en el tintero, por ejemplo, las Gilera SP01 y SP02 que tuvieron copas monomarca de gran éxito en España y de donde salieron pilotos como Sete Gibernau. Quizás tengamos que volver sobre este tema porque una cosa está clara: los motores de dos tiempos ofrecen unas sensaciones únicas, incluso un sonido y un olor únicos y quien los ha probado, nunca los olvida.

This week's EYE on NPI is one I've personally got an EYE on for a few months: the TI BQ25792 I2C Controlled, 1-4 Cell, 5-A Buck-Boost Battery Charger. This luxurious charger caught my eye a few months ago and now it's available for purchase and I'm really excited about it. This chip does everything you could ever want from a battery charger. We showed off a charger chip last week that was designed specifically for ultra-low current and voltages - great for TEC's or small solar cells. But what if you want HUGE charging capabilities? The TI BQ25792 has you covered, no matter your application. First great thing - support for any size battery. We have lots of battery packs in the Adafruit shop, and in particular we use 1S batteries - if there's more batteries they are wired in series. But there's lot of folks who are building robotics that require higher voltages, so they have 2S, 3S, or 4S batteries. This charger can handle any of em, and you can configure the battery pack size using a simple resistor on the PROG port. Second great thing - support for just about any voltage power supply input. Once you set the battery size, the output charging voltage has to be 4.2V-per-cell. Normally that means that if you're charging a 1S battery, you'd want a 5V power supply (4.2V plus some headroom). For 2S you want 9V to 12V, etc. Sometimes you'll see buck or boost chargers that let you have a lower or higher voltage. This chip is a buck-boost so you can have anything from 3.6V to 25V input and it will do the right thing to get you the voltage you need to charge the battery pack you have. There's some efficiency-loss on conversion, but much less than a linear supply and you don't have to worry about needing the exact-right power adapter or USB power supply. (https://e2e.ti.com/blogs_/b/powerhouse/posts/universal-and-fast-charging-a-future-trend-for-battery-powered-applications) OK we've done the output, we've done the input. Now lets look at the creamy middle: This charger has our favorite TI-capability: VINDPM and IINDPM - the ability to track the input voltage to make sure it is not drooping from over-draw. Say you have a battery, you want to charge it at 2A, but the wall adapter maxes out at 1A - you don't want the voltage to collapse on you, it's better to charge slowly at 1A than not at all at 2A. VINDPM/IINDPM auto-monitors the voltage and if it starts dropping, it will reduce the current draw. There's also ICO, which attempts to find the max-power-point for the power adapter, which may not be the exact same thing since there's different buck-boost efficiencies at different voltages. For when you're using USB for power, the charger can auto-detect the 'Apple-style' resistors used to set the max-draw current available. (In theory, we acknowledge it's probably better to just VINDPM/IINDPM when possible but we figure it's also polite to stick to the max-current-draw set by the chargers. Finally, there is an "OTG" mode where the converter 'turns around' and can be a buck-boost that runs off the battery to charge another device. Really a wonderful chip with a lot of capabilities and looks like no matter what it is you're trying to charge or power! I'm ordering some BQ25792 today for a new design I'm working on. From the looks of this datasheet, TI really stepped it up here (pun intended!) to make a battery charger everyone will love. Check out TI's video for a lot more details (https://www.youtube.com/watch?v=Wjk5YWrt8Ww) The BQ25792 is stock right now, for immediate shipment from Digi-Key (https://www.digikey.com/en/products/detail/texas-instruments/BQ25792RQMR/13577777) See on Digi-Key at https://www.digikey.com/short/3q2mnt5t

#796 Qual letra mata?Leitura: Marcos 9:2-6Vídeo: https://youtu.be/NK04YK4an08Ao descer do monte, após receber as tábuas de pedra da Lei, Moisés encontrou o povo entregue à idolatria. O juízo de Deus por isso levou ao massacre de três mil pessoas. Após Moisés interagir com o Senhor as pessoas viam que seu rosto “resplandecia. Então, de novo Moisés cobria o rosto com o véu até entrar de novo para falar com o Senhor.” (Êx 34:35). Aquele brilho de sua face não era permanente, mas se desvanecia.Agora ligue os pontos: Se naquela ocasião Moisés havia subido ao monte e ficado com o rosto resplandecente, como Pedro, Tiago e João podiam interpretar aquilo que agora viam? Tinha o monte, tinha Moisés, e a diferença é que agora era Jesus o resplandecente, “transfigurado diante deles. Suas roupas se tornaram brancas, de um branco resplandecente, como nenhum lavandeiro no mundo seria capaz de branqueá-las.” (Mc 9:2-3). Se o roteiro fosse o mesmo de Êxodo o próximo evento seria um massacre. Entende agora a razão de eles estarem apavorados?Mais tarde Paulo iria deixar claro que o relacionamento que os discípulos de Cristo teriam com Deus, particularmente após a formação da Igreja, não seria o mesmo que os israelitas tiveram no passado. Paulo diz:“[Deus] nos capacitou para sermos ministros de uma nova aliança, não da letra, mas do Espírito; pois a letra mata, mas o Espírito vivifica. O ministério que trouxe a morte foi gravado com letras em pedras; mas esse ministério veio com tal glória que os israelitas não podiam fixar os olhos na face de Moisés por causa do resplendor do seu rosto, ainda que desvanecente. Não será o ministério do Espírito ainda muito mais glorioso? Se era glorioso o ministério que trouxe condenação, quanto mais glorioso será o ministério que produz justiça!” (2 Co 3:6-9).Alguns pregadores ameaçam seus ouvintes com o bordão “a letra mata, mas o Espírito vivifica”, se estes quiserem conferir se pregam de acordo com a Bíblia. São falsos mestres que aconselham seus ouvintes a não ir pelo que está escrito, mas aceitar suas supostas revelações como pão quente saído do forno. A “letra” de que Paulo fala era a Lei, que levava à morte, “porque, aquilo que a lei fora incapaz de fazer por estar enfraquecida pela carne, Deus o fez, enviando seu próprio Filho, à semelhança do homem pecador, como oferta pelo pecado e condenou o pecado na carne.” (Rm 8:3). Meu conselho? Fuja dos que desencorajam você a ler a Bíblia insistindo que o que eles dizem é revelação do Espírito. See acast.com/privacy for privacy and opt-out information.

#795 Ele e' incomparavelLeitura: Marcos 9:2-6Vídeo: https://youtu.be/CXfODEya-k4“Seis dias depois, Jesus tomou consigo Pedro, Tiago e João e os levou a um alto monte, onde ficaram a sós. Ali ele foi transfigurado diante deles. Suas roupas se tornaram brancas, de um branco resplandecente, como nenhum lavandeiro no mundo seria capaz de branqueá-las.” (Mc 9:2-3). Esses três discípulos representavam ali o remanescente de judeus fieis que se levantará nos tempos de grande tribulação que precedem a vinda de Cristo para reinar. É a esse remanescente ainda futuro que o Senhor fala através do profeta Malaquias, numa antevisão do que seria, não apenas a transfiguração, mas o próprio estabelecimento do Reino na terra.“Para vocês que reverenciam o meu nome, o Sol da justiça se levantará trazendo cura em suas asas. E vocês sairão e saltarão como bezerros soltos do curral. Depois esmagarão os ímpios, que serão como pó sob as solas dos seus pés no dia em que eu agir... Lembrem-se da lei do meu servo Moisés, dos decretos e das ordenanças que lhe dei em Horebe para todo o povo de Israel. Vejam, eu enviarei a vocês o profeta Elias antes do grande e terrível dia do Senhor. Ele fará com que os corações dos pais se voltem para seus filhos, e os corações dos filhos para seus pais; do contrário eu virei e castigarei a terra com maldição.”(Ml 4:2-6).São esses mesmos Moisés e Elias que vemos aqui no monte da transfiguração: “E apareceram diante deles Elias e Moisés, os quais conversavam com Jesus. Então Pedro disse a Jesus: ‘Mestre, é bom estarmos aqui. Façamos três tendas: uma para ti, uma para Moisés e uma para Elias’. Ele não sabia o que dizer, pois estavam apavorados.”(Mc 9:4-6). Os discípulos parecem não ter percebido que o único que aparece transfigurado em resplendor é Jesus e querem colocá-lo no mesmo nível dos dois grandes profetas de Israel, em três tendas iguais.Apesar de muitos acharem que Jesus é apenas um grande profeta, Deus deixa claro o que pensa dele: “Apareceu uma nuvem e os envolveu, e dela saiu uma voz, que disse: ‘Este é o meu Filho amado. Ouçam-no!’ Repentinamente, quando olharam ao redor, não viram mais ninguém, a não ser Jesus.” (Mc 9:7-8). Jesus é incomparável, ele é “o Filho, a quem [Deus] constituiu herdeiro de todas as coisas e por meio de quem fez o universo.

In episode 8 of the Bally Alley Astrocast, Paul, Michael and I review the 4K Blast Droids cartridge that Esoterica released in 1983. This game was written by Dan Drescher, and J.P. Curran. We also review the BASIC game Haunted House released by New Image in 1981. Paul and I discuss the contents and programs included in the August and September 1979 issues of the Arcadian newsletter. We also read feedback from Arcadian readers that sent letters and postcards to Bob Fabris concerning the July 1979 survey question that asked if users would purchase a third-party keyboard and RAM upgrade. Lastly, we cover about ten letters that cover general topics that were sent to the Arcadian from late July to September 1979.

Haunted House Bally BASIC Instructions - These are the program instructions and BASIC listings for New Image's Haunted House. This game is very unusual because it is made up of nine different loads, each of which is a separate BASIC program. Haunted House "AstroBASIC" Instructions Treasures of Cathy ("AstroBASIC" Program) - This programs, by John Collins, seems like a fairly complex dungeon-crawler type game. The Crown of Zeus by Todd Johnson - This game is probably the most RPG-like game on the Astrocade. It is for AstroBASIC only. It takes you to a dark decaying castle in the evil land of Sorom. You've been asked, as the best warrior in the land of Beekum, to retrieve the Crown of Zeus which the Scromites have stolen. The crown, when worn, gives the wearer the awesome ability to cause anything he or she wishes to vanish. Apparently the Scromites have not yet discovered the crown's powers. But as you hid in the forest outside the castle, you saw a troop of orcs from the warring land of Machor slip in through the front gate. They surely know the power of the crown and will have to be dealt with... Arcadian Newsletter Arcadian 1, no. 9 (Aug. 18, 1979): 69-76. - The ninth issue of the Arcadian newsletter. Arcadian 1, no. 10 (Sep. 31, 1979): 77-84. - The tenth issue of the Arcadian newsletter. Arcadian 1, no. 10a (Sep. 31, 1979): 80a. - A supplemental page to the tenth issue of the Arcadian newsletter. TV Output Notes by Marc Calson (possibly a misspelling of Mark Carlson). - The four pages of this document were created using the output of a short 10-line, BASIC program. Whoever sent this document to Bob methodically noted down four sets of numbers for each ASCII character. I can't say that I understand the listed decimal number information, but it seems to nicely supplement the August 1979 issue of the Arcadian's music coverage from Robert Hood (American Concert Frequencies) and the second part of Chuck Thomka's music tutorial, The Music Synthesizer. Hit the Pedestrian by Sebree's Computing (Timothy Hays) - This is a hand-written type-in program listing for Bally BASIC. Typed instructions are included. This program has not be digitally archived. Pictures of the Viper RAM Expansion - This hardware was released by Alternative Engineering. Pictures of the Keyboard for the Viper RAM Expansion Unit Aldo Trilogy by Dave and Benjamin Ibach - Three PC shareware titles for DOS released 1987-1991. These games do not run on the Astrocade. These games will run well under Windows when using a program called DOSBox (an emulator, of sorts). The games included are: Aldo's Adventure, Aldo Again, and Aldo's Assault. While these games won't run on the Astrocade, they do give a continued history of what Dave Ibach did (with his son) after he moved on from the Astrocade. The main character in this series of one-screen platform games looks suspiciously like someone named...Mario. Give these games a try-- you'll like 'em. The Bit Fidder's Corner by Andy Guevara - The Bit Fiddler's Corner is an Astrocade machine language programming tutorial that ran as a series of serialized articles in the Arcadian newsletter in 1983 and 1984. The author, Andy Guevara, programmed the Machine Language Manager cartridge for the Bally Arcade/Astrocade. This tutorial complements that cartridge, but has a general focus so this information can be used without reinterpretation by Astrocade assembly programmers, or those wishing to learn about the machine. The Music Synthesizer by Chuck Thomka - A tutorial on creating sound effects for the Astrocade. Black Box by B. Reany. - This Bally BASIC (300-baud) program was printed on page 74 of the August 1979 issue of the Arcadian. Black Box is a sort of Battleship game where the computer hides some "atoms" in a grid and you have to locate them. Use the diagram for clues. Space War by Dave Ibach - A 300-baud, Bally BASIC game that was printed in the September 1979 issue of the Arcadian. It's a neat idea for a two player game. Each player has a ship on one side of the screen, and can move up and down and fire at any angle. However, the ships are invisible, so you can only figure out where your opponent is when they fire a shot. XY Tutorial by Timothy Hays - A 12-page tutorial on the Bally BASIC XY command for exceptionally well controlled graphics. XY Tutorial Programs by Timothy Hays - This archive includes the Bally BASIC programs included with the XY Tutorial document. The six programs included are: 3-D Forward Simulation Above A Flat Plane, Cartesian Coordinates To XY Values Routine, Demonstration Program #2, Demonstration Program #2 (with Additions), Demonstration Program #4, and RND XY Value To Perspective Point. Responses to the Arcadian July 1979 Survey These letters relate to the programming keyboard survey on page 55 of the July 1979 issue of Arcadian. As a reminder, the survey questions were: "Assume that the Bally keyboard is available with full capacity (reference page 21). Are you ready to pay $650 for it? "Assume that the Bally keyboard is available with partial capacity (reference page 54). Are you ready to pay $350 for it? "Assume that we develop a keyboard that would have 16K RAM with upgrading capability of 24-plus K RAM, and some form of resident BASIC in 16K ROM, along with some features such as cassette motor control, word processing capability, etc. Are you ready to pay $350 for it? (Assuming that Bally does not produce in the same timeframe.) "A postal card with numbers down the side and yes/no opposite each is all that is necessary, but suggestions are certainly welcome. Also, tell me the model number and serial number of your machine if you haven't done so yet." Letter from Paul Zibits to Bob Fabris. (Approximately July/August 1979). Letter from Kirk Gregg to Bob Fabris. (Approximately July/August 1979). Letter From "Levin" to Bob Fabris. (July 31, 1979). Letter from M. Lewitzke to Bob Fabris. (August 2, 1979).

Letter from George Tucker to Bob Fabris. (October 16, 1979). Letters to the Arcadian Letter from Chuck Thomka to Bob Fabris. (1979, probably late January). - Chuck sent two programs with this letter: Modified Player Piano for Learning Aid on the &16 - &23 Commands and Leaning Aid for "&" Command. It seems that these two programs helped Chuck figure-out the sound capability of the Bally Arcade. He went on to use this information to write the Music Synthesizer tutorials in the July and August 1979 issues of the Arcadian. Chuck describes the printer that he uses to create the BASIC listing forms, "It actually doesn't take too long to create a form on what I use, which is a cross between a computer and a very high-speed line printer. It puts images on paper with laser optics utilizes Xerox xerographics. It's really quite an impressive machine. As an example of what can be done with it, well, if you can envision an 8 1/2" x 11" blank piece of paper and another 8 1/2" x 11" completely black piece of paper, this represents the extremes of the machine. Everything in-between (just about) can be done by this machine. That includes all different font sizes and styles, logos, lines and even signatures! All this with about the resolution of 300 dots to the inch. The speed of this machine is two full pages a second. If you wanted to print with a reduced print style and also have put two sides of data on the same side of the paper, this machine would print at equivalent speed of 36,000 lines per minute! Like I said, a very high-speed line printer!" Leaning Aid for '&' Command by Chuck Thomka. - A five-page program that is purely Chuck's own concoction. This program uses all but about 150 bytes of memory and is somewhat involved, but is informative as to the workings of all the possible '&' commands. Modified Player Piano for Learning Aid on the &16 - &23 Commands by Chuck Thomka - Submitted to Arcadian on January 5, 1979, but previously unpublished. A single-page modification to an existing Bally program which allows easy and quick changes to '&16' through '&23 commands [the sound ports]. Dealers of Lightning: Xerox PARC and the Dawn of the Computer Age by Michael A. Hiltzik - Chuck Thomka works worked a Xerox, and he mentioned what sounds like a laser printer in his letter. This is an Amazon.com link to Dealers of Lightning, a book published in 2000. The creation of the laser printer is discussed in some detail here. It "is a fascinating journey of intellectual creation. In the 1970s and '80s, Xerox Corporation brought together a brain-trust of engineering geniuses, a group of computer eccentrics dubbed PARC. This brilliant group created several monumental innovations that triggered a technological revolution, including the first personal computer, the laser printer, and the graphical interface (one of the main precursors of the Internet), only to see these breakthroughs rejected by the corporation. Yet, instead of giving up, these determined inventors turned their ideas into empires that radically altered contemporary life and changed the world." Letter from Tracy Crook to Bob Fabris. (About 1979). - "I wanted to let you know where I am on the Bally expansion. So far, I've added 16K RAM, one serial port, two parallel ports and an ASCII keyboard. These all work very well. What has not worked so well, is some special logic used with the non-mask will direct. With this, I had hoped to use the Bally BASIC unmodified with the keyboard I added. As it is, I can input data from the keyboard under basic control (or machine language), but program entry and editing must still be done through the keypad. I can't get this to work, I guess Bally BASIC (or some other language) could be placed in RAM. A commented listing of Bally BASIC would be invaluable at this point. [...] With that info, we could tailor it a bit and put it in RAM. "At this point, I see the remainder of the expansion to be mainly a software effort, which is where I could use some help. The most important changes, I think, would be to get BASIC program storage out of internal (graphics) memory. This would greatly increase the color capabilities when using BASIC." [Note: Blue Ram BASIC does this, which is why more colors are available to this expanded BASIC.] "Another interesting possibility open by having RAM memory available is the ability to load it with data from any of the game cartridges (which were previously dumped onto a cassette tape) and then switch this memory into the bank normally signed the plug-in cartridge. This is quite easy to do. At this point the Bally would perform exactly as if you had plugged in the game cartridge that the data came from." [The Blue Ram, Viper and Lil' White RAM expansion units all allow for this.] "The end result would be that you could have the entire library of Bally games in a couple of cassette tapes. Bally might not be too wild about this idea, I assure you it would work." "In the meantime, in order to ease programming the Bally, I use another one of the microcomputers I own, which has an ASCII keyboard, to write Bally BASIC programs on and then dump them on tape in a format compatible with the Bally. Doing it off like this has some disadvantages, but it sure beats that key pad." "Haven't done much on it lately, as my Bally was struck by lightning about five weeks ago, and it still not back from the factory." Letter from Ed Mulholland to Bob Fabris. (July 1, 1979 / July 23, 1979). - In the July 1'st letter, Ed says, "The schematics to our Ballys show a 10-pin and a 26-pin port in addition to the IEEE-488 port. My machine did not have 26-pin port as shown in the photo on page 14 of the [Bally PA-1] service. This would still be only a small inconvenience because the pin numbers and functions as shown on the schematic." The second part of the letter (dated July 23) shows how the 10-wire 24-key keypad is arranged. I think that this information is meant to help explain how to wire a 63-key "full size" ASCII keyboard in parallel with the 24-key keypad. Letter from Robert Dahl to Bob Fabris. (July 29, 1979). - Mr. Dahl suggests that future issues the Arcadian leave room so that a hole punch can be used so that the issues can be stored in a binder. He says, "They are well worth saving." I agree! On July 27, Mr. Dahl received a mimeographed copy of the Hacker's Manual from Bally. He notes that they included a letter that says they do not expect the keyboard expansion to be released this year Robert Dahl notes that he was able to order the Amazing Maze/Tic-Tac-Toe cartridge from Montgomery Ward's catalog. He got the cartridge in just three days. He adds that a fellow, who sells the Arcade and its accessories, tells him that he has a standing order for all arcade items, but gets more promises than anything else from a wholesale distributor in Milwaukee. This man had been trying to get the Amazing Maze cartridge ever since he first heard about it and he had yet to get it. Mr. Dahl figures that Bally's distribution must be out of whack. Mr. Dahl has typed in various versions of Slot Machine. He talks about three that he has used comparing and contrasting differences between them. Mr. Dahl makes a comment that the Checkers game number six had him puzzled. He was expecting a regular checkerboard on the TV screen. He says that, "Right now, it's beginning to soak-in that I should take a checkerboard and number the squares and move the pieces around as the numbers on the screen direct?" [Is this accurate?!?] Letter from Andy Guevara to Bob Fabris. (July 30, 1979). - Andy Guevara wrote several programs that were published in the Arcadian and Cursor/BASIC Express newsletters. Andy programmed the Machine Language Manager, a 2K cartridge that was released in 1982 by The Bit Fiddlers. He released a few tapes, including Candy Man and Chicken, two games released on tape that were written in mostly machine language. He wrote Ms. Candyman and Sea Devil, both of which are 4K cartridges that were released 1983 by L&M Software. Mr. Guevara also wrote The Bit Fiddler's Corner, an Astrocade machine language programming tutorial that ran as a series of serialized articles in the Arcadian newsletter in 1983 and 1984. Andy just received his first stack of Arcadian newsletters. He has had his Bally arcade for five months and never dreamed that so much information could be further developed. He has dumped the Baseball cartridge, and is pleased to see that other people have made ROM dumps too. Mr. Guevera is looking into expanding his internal memory from 4K to 12K of RAM with a single IC designed by Harris Semiconductor. He goes into detail about how this might work. Andy has come up with a solution for Bob to be able to print programs. He provides details and a schematic on a device that can be used that will use a UART to allow the Bally to print. Although Andy has only had his Bally Professional Arcade model BPA-1100 for five months, the innards have already had to be changed twice. Letter from Richard Dermody to Bob Fabris. (July 31, 1979).- Richard's interest has been piqued by the announcement of the keyboard project. So much so, that he has already gone out and bought a keyboard for the project. He says, the "glimmer of a future for the Arcade as a computer [...] has prompted [him] to retain his [Arcade] with hopes for the future." Richard notes that while he understands the difficulties that Bally may be having with the FCC, he has noticed that other companies, such as Apple, have made significant progress in the same time period since the Arcade was first announced. Richard is on his second Bally arcade. He had to return his first one to Montgomery Ward as "it tended to self-destruct after being in operation for a while." Mr. Dermody hopes that reviews of the Bally cartridges will be in future issues. There is no local retailer for these items where he lives so his only resort is mail-order. He would like to have some idea of what he is ordering before he places an order. Letter from Guy McLimore to Bob Fabris. (July 31, 1979).- Guy gives an unqualified "yes" to all the survey questions that Bob asked the previous issue of the Arcadian. Guy says that he wants and needs a keyboard badly. An interesting bit here is that Ken Ballard, the owner of ABC Hobbycraft, has commissioned a professional hardware/software man to develop a 64K keyboard memory expansion to be sold commercially. The unit is still in the planning stages, but [they] hope that it will be ready by December." This seems overly optimistic, since it is nearly August already. I don't recall ever hearing about this from any other source. It is interesting that so many people wanted to build, create or purchase a memory expansion/keyboard for their Bally unit. Guy really enjoyed Chuck Thomka's synthesizer tutorial. He found the two accompanying programs very useful. He does wonder how Bell Telephone feels about the programs, however. He notes that if you add the buttons A-D to the Touch-Tone dialer program (Touch Tone Simulate), then you have a semi-efficient Black Box for receiving free telephone calls. The Touch-Tone dialer doesn't work in Guy's local area. He thinks that Indiana Bell has an acoustical filter that prevents Touch-Tone signals from being input to the microphone from the handset. By popular demand, ABC hobby craft is now accepting mail orders for Bally hardware, W&W software, Stocker Software, and Skyrocket Software (Guy's company). Guys makes an observation about the tape quality for software that is being sold through the Arcadian classified ads. It seems that the people distributing their software on tape are using cheap tapes brands which makes loading the tapes difficult. He notes that the Dave Stocker software is also available on micro cassettes. I don't know of any other Bally software that was distributed on these tiny tapes. Guy has been pleasantly surprised by the amount of response he received to the listing of his Fantasy Games #1 package in the Arcadian. Despite the fact that it is a limited program designed only for those persons familiar with fantasy role-playing games, such as Dungeons & Dragons, the program sold remarkably well! Phenomenally well, in fact, given an audience of relatively few people. Guy will be creating programs under the name Skyrocket Software with his partner Greg Poehlein. They intend to sell software for the Bally, TRS-80 and eventually other systems. He says they won't be turning it out fast, but they will be turning it out good, paralleling Bally's own stated policy of producing fewer top quality cartridges as opposed to Atari's more is better philosophy Letter from Jeff Frederiksen to Bob Fabris. (August, 20 1979).- This letter is from Jeff Frederiksen, the chief engineer behind designing the Bally Professional Arcade hardware. It seems that this letter was accompanied by some hardware. The letter simply states: "The enclosed assemblies replace the 75361 clock driver, located in the oscillator shield. The failure of the 75361 is that the 6V high time after warm-up drops below 55ns causing the data chip to appear defective. If you do not have this sinking clock syndrome, replacement is not necessary. I hope you find the enclosed hardware description useful." Letter from Jeff Grothaus to Bob Fabris. (August 31, 1979). - Jeff is building his own cassette tape interface from the schematics on page 20 of the Arcadian and page 4 of the Bally Hacker's Manual. He has run into a few difficulties and is hoping to get some help. He also wonders if Bob knows if anyone else has created a working interface from the schematics. There's a handwritten note from Bob where he simply writes, "No." I find it interesting that Jeff is actually building his own tape interface. This interface would be of no use without the basic cartridge. At the time, I think, the tape interface was easy enough to get for $50. I wonder if Jeff was trying to save money, or if he was having difficulty finding the necessary hardware to use with Bally BASIC and a tape recorder. Letter from Karen Nelson to Bob Fabris. (September 10, 1979). - Karen is a programmer who got interested in the Bally when JS&A advertised it in Scientific American in 1977. She was told that she was one of the first people to get her hands on one. She was very excited about machines potential, but was disillusioned by the heat problems which were inherent in the first machines. She "burned out" two of the units. Just after she returned the second unit, she discovered that her programming instructor was doing the graphics for the Bally. She says, "Yes, folks, it was the infamous Tom DeFanti and his magic Z-GRASS." She knows Tom well enough to drop into his "Graphics Habitat" at the University of Chicago to talk intelligently about some of his projects. She also knows Nola Donato and a few other of Tom students who are working on projects for Bally. Tom has had the University of Chicago purchase eight Bally's and eight Sony TVs to teach students the basics of computers and programming. In August 1979, Tom was the chairman of a traffic seminar held jointly by IEEE and ACM/SIGGRAPH. For three nights, Tom and his crew presented new and interesting works in various areas of computer graphics (including a few by people using Bally Arcades). In addition to the seminar, a graphics experiment Expo was held and it was there that Karen met some of the guys from Dave Nutting, in particular Ricky Spiece (who developed the Football cartridge). Ricky was helpful and showed Karen some tricks (like the ports in BASIC), and he also demonstrated the graphics capabilities by loading a picture from a disk to a color monitor. In addition, his Bally was connected to a B&W monitor and a keyboard. His commands appeared on the black-and-white monitor, and the graphics were displayed on the color monitor. However, the whole setup was attached with the Bally board mounted in a frame, not in the case, which leads Karen to believe that some special wiring is needed. Karen describes her experimentation with the different ports available in BASIC. Karen has recently seen the pinball cartridge demoed at the graphic seminar. She says that it looks pretty good. She heard one of the Dave Nutting guys say that he had just sent the thing off to Bally and that it should be out on the market pretty soon. Karen says that there was a demo of Z-GRASS, but that she didn't get to see it. She does note that as a student of De Fanti, she learned how to program in GRASS-- Z-GRASS's daddy-- using a PDP-11/45. Karen is glad to find out that there are other people like her who think that the Bally Arcade/computer has a lot more potential than most people give it credit for. She hopes that Bob Fabris might be able to pass on some information to whoever the marketing manager at Bally is. She would like to see the Bally advertisement computer magazines such as BYTE and Personal Computing. She would like to see Bally stress that most people buy home computers for games and that Bally has terrific controls, and that by the time people become interested in programming, Bally will have add-on module available. She also says that the graphics capabilities of the Bally have no competition; they are the best, and the Arcade is dirt cheap when compared to other systems.

Cuando estamos inmersos en nuestro mundo, muchas veces no nos damos cuenta de lo que sucede a nuestro alrededor. Esto es precisamente lo que me ha pasado con el ESP8266. Siempre he estado rodeado de Arduino y soy un fiel defensor de esta placa. Hace ya algún tiempo cayó en mis manos un módulo ESP-01. Estuve trasteando con el varios meses y jugando con los comandos AT. Pero realmente cuando he visto el potencial que tiene, ha sido preparando este capítulo del podcast.Gracias a Germán Martín, un fiel seguidor de Programarafacil, he podido descubrir el abanico de posibilidades que nos brinda. Hoy vamos a hablar de todo esto. Analizaremos la actualidad de este microcontrolador y pondremos todas las cartas sobre la mesa. Si en apenas dos años ha conseguido crear diferentes módulos destinados a diferentes fines, lo mejor está todavía por llegar. Comenzaremos hablando de sus orígenes y sus posibles usos. Luego veremos detalladamente sus especificaciones técnicas. Por último analizaremos los diferentes módulos que podemos encontrar en el mercado y los diferentes métodos para programar el ESP8266.Qué es el ESP8266Cuando salió el Arduino MKR1000, afirmé que revolucionaría el mundo de los objetos conectados, sobre todo por la facilidad de uso que caracteriza a estas placas. Acercaba de una manera sencilla el IoT a la población civil. Pero lo que está ocurriendo con el ESP8266, puede reventar las nuevas tendencias de muchos sectores. Se trata de un chip integrado con conexión WiFi y compatible con el protocolo TCP/IP. El objetivo principal es dar acceso a cualquier microcontrolador a una red.En este artículo haré referencia en varias ocasiones a Arduino y es que, sin duda alguna, es la competencia del Shield WiFi para esta placa. Pero no solo eso, Atmel, el fabricante que provee de microcontroladores a Arduino, sacó al mercado el ATSAMW25, competencia directa del ESP8266. Este microcontrolador es el que incorpora el Arduino MKR1000.La gran diferencia entre el ESP8266 y el ATSAMW25 es el precio. Mientras que podemos encontrar módulos con el chip ESP por 3€, el Arduino MKR1000 sale por unos 40€ con gastos de envío.La diferencia es abismal aunque tiene su sentido. La versión más básica del ESP es la 01 y dista mucho de la facilidad de uso que tiene el Arduino MKR1000, aunque el objetivo de este artículo no es hacer una comparativa entre ellos.La gran ventaja del ESP8266 es su bajo consumo. Es el producto ideal para wereables y dispositivos del IoT.Un poco de historiaNo voy a profundizar en la historia detrás de este chip. Puedes encontrar mucha información en la red. La empresa que lo creo y lo fabrica es Espressif, una empresa China situada en Shangai.Aunque parece que lleva con nosotros mucho tiempo, lo cierto es que vio la luz en agosto del 2014, en su versión básica el módulo ESP-01 de la mano de AI-Thinker. Ese mismo mes comenzó la era de reinado del ESP. Todos aquellos que pudieron hacerse con uno quedaron fascinados por su bajo precio y las posibilidades que tenía. En aquella época el gran problema era la documentación, estaba toda en Chino.Poco a poco, la gran comunidad que hay detrás, comenzó a traducir la documentación y crear firmwares pare el ESP8266. Un firmware no es más que el software de bajo nivel, la lógica que controla los circuitos electrónicos. Todo empezó a crecer y las aplicaciones se multiplicaron. En la actualidad podemos encontrar multitud de módulos que incorporan este microcontrolador.A mediados de este año (2016), la empresa anunció una nueva versión, el ESP8285. Parecía un clon de su predecesor. La gran diferencia es que incorpora una memoria Flash de 1MB integrada dentro del propio chip. El ESP8266 no dispone de esta memoria y necesita de un módulo externo para almacenar los programas. Esto va a permitir crear dispositivos del IoT, o de otro tipo, del tamaño de una tecla de un teclado, todo un reto. Todo gracias a la conectividad y a la memoria Flash que incorpora.Posibles usos del ESP8266En este punto debemos de distinguir entre los módulos y los microcontroladores. El ESP8266 y el ESP8285 son microcontroladores. Podemos trabajar con ellos sueltos o podemos comprarlo integrado dentro de un PCB (Printed Circuit Board o Circuito Impreso).Ocurre lo mismo que con Arduino. Tenemos la posibilidad de comprar un microcontrolador Atmel o comprar la placa de Arduino donde ya viene integrado.Dicho todo esto, el uso que le demos dependerá de si lo tenemos como chip o como módulo. Dentro de la gran cantidad de usos caben destacar los siguientes:Electrodomésticos conectados.Automatización del hogar.Casas inteligente. ITEAD es puntera en este sector.Automatización de la industria.Monitor de bebés.Cámaras IP.Redes de sensores.Wereables.IoT (Internet of Things o Internet de las Cosas)IIoT (Industrial Internet of Things o Internet de las Cosas para el sector Industrial)Y cualquier aplicación donde se requiera conexión a una red o a Internet.Especificaciones del chip ESP8266No me cansaré de repetir que lo primero que debemos hacer cuando adquirimos un nuevo componente es mirar la hoja de especificaciones técnicas. La empresa Espressif nos facilita dicha hoja en Inglés. A continuación haré un resumen de lo más importante.HardwareUtiliza una CPU Tensilica L106 32-bitVoltaje de operación entre 3V y 3,6VCorriente de operación 80 mATemperatura de operación -40ºC y 125ºCConectividadSoporta IPv4 y los protocolos TCP/UDP/HTTP/FTPNo soporta HTTPS en un principio. Si que lo hace mediante software tanto en cliente como servidor TLS1.2. La primera implementación está todavía en desarrollo.Puertos GPIO (de propósito general)Tiene 17 puertos GPIO pero solo se pueden usar 9 o 10. El GPIO16 es especial ya que está conectado al RTC (Real Time Clock).Pueden ser configurados con resistencia Pull-up o Pull-down.Soporta los principales buses de comunicación (SPI, I2C, UART).Características eléctricasVoltaje de trabajo entre 3V y 3,6V.Según noticias del propio CEO de Espressif, admite tensiones de entrada de 5V e los puertos GPIO.ConsumosDependerá de diferentes factores como el modo en el que esté trabajando el ESP8266, de los protocolos que estemos utilizando, de la calidad de la señal WiFi y sobre todo de si enviamos o recibimos información a través de la WiFi. Oscilan entre los 0,5 μA (microamperios) cuando el dispositivo está apagado y los 170 mA cuando transmitimos a tope de señal.Modos de operaciónDebido a los sectores a los que va enfocado, wereables, dispositivos del IoT y móviles, el ESP8266 requiere de una gestión de energía eficaz. Dispone de una arquitectura de bajo consumo que trabaja en 3 modos.Active mode o modo activo: a pleno rendimiento.Sleep mode o modo dormido: solo el RTC (Real Time Clock) está activo para mantener la sincronización. Se queda en modo alerta de los posibles eventos que le hagan despertar. Mantiene en memoria los datos de conexión y así no hace falta volver a establecer la conexión con la WiFi. Consume entre 0,6 mA y 1 mA.Deep sleep o modo en sueño profundo: el RTC está encendido pero no operativo. Debe pasar por el modo dormido antes de despertar. Hay que llevar especial cuidado con los datos ya que en este estado es como si estuviera apagado y todos los datos que no estén almacenados se pierden. Consume alrededor de 20 μA.Módulos ESP-XXAl igual que con Arduino, donde trabajamos con la placa o circuito integrado, con el ESP8266 ocurre exactamente lo mismo. El fabricante AI-Thinker proporciona la serie ESP con diferentes modelos para diferentes usos. A parte han ido surgiendo diferentes placas que incorporan algún módulo ESP como el NodeMCU.

Este programa se lo dedicamos a cómo destruir Arduino. La idea es que si sabemos cómo podemos destruirla podremos evitarlo. Os recomendamos que no lo probéis en casa si no queréis quedaros sin placa.Y como siempre, recuerda que tenemos activa la encuesta para los oyentes. Cualquier duda nos la puedes hacer llegar a través del formulario de contacto, por Twitter y Facebook. Y si quieres estar al día de las novedades de nuestra web la lista de distribución te está esperando.En este capitulo te contamos casos que nos han ocurrido a nosotros y algún oyente como intentando arreglar tecnología hemos tenido un resultado fatal para estas. En otras palabras, cómo nos hemos cargado tecnología por falta de conocimientos y/o despiste.Nos gustaría que nos dejaras en los comentarios de este post tu experiencia. Como sin quererlo has conseguido que una aparato se convierta en un bonito pisapapeles, jejeje. Puede ser divertido ver como a todos nos ha ocurrido alguna vez y así entre todos aprenderemos que no hay que hacer. No tiene que ser con Arduino, sino con cualquier aparato: móvil, ordenador, videoconsola, etc...La idea que os queremos remarcar en este capitulo es que no debemos avergonzarnos de nuestros errores, con ellos siempre aprendemos y siempre más vale fallar por haberlo intentado que no fallar por no atreverse a intentarlo.Y antes de poneros los métodos para destruir Arduino, Jose, un oyente de este programa nos recomienda utilizar una fuente ATX para alimentar un circuito. Con esta fuente tenemos salidas de 12V, 5V y 3.3V y si además le añadimos un reductor de voltaje podremos obtener la energía que buscamosY veamos los métodos para conseguir un bonito pisapapeles con Arduino, esta información la hemos sacado de la pagina Rugged Circuits donde nos venden otra placa mejorando otra placa (esto no quiere decir que nosotros la recomendemos, ni la hemos probado ni hemos contrastado estas mejoras):Método # 1: El cortocircuito pines E/S a TierraCómo:Configuramos un pin de E/S y lo establecemos a nivel alto (HIGH). Llevamos el pin a la tierra. Hemos creado una condición de sobrecorriente en el pin E/S y será destruidoPorque:En la hoja de datos del microcontrolador específica que tiene como máximo por pin 40mA con una resistencia de 25 ohmios. Al realizar este corto podemos transmitir 200mA. Lo suficiente para freír el microcontroladorMétodo # 2: Un cortocircuito pines E/S el uno al otroCómo:Configuramos dos pines E/S para ser salida y establecemos una a nivel alto y otro a bajo. Ahora conectamos las clavijas juntos. Hemos creado una condición de sobrecorriente en ambos pines de E/S y serán destruidos.Porque:El flujo de corriente es similar al anterior error. Excepto el camino de retorno de tierra que sería a través del microcontrolador.Método # 3: Aplicar sobretensión de pines E/SCómo:Aplicando una tensión superior a 5,5V a cualquier pin de E/S. Destruiremos el pin.Porque:Con esta acción polarizamos el diodo de protección (ESD) incorporado al microcontrolador. Este esta preparado para aguantar una tensión superior a 5V (unos 0.5V) pero solo por un tiempo (pensado por descarga electrostática). Si continua en el tiempo se quemara este diodo de protección y después destruirá el pin E/S podiendo afectar a más componentes de la placa.Método # 4: Aplicar energía externa en el pin Vin invirtiendo la polaridadCómo:Aplicamos energía a nuestro Arduino a través de la clavija de conexión Vin, pero invertimos la polaridad de la conexión de alimentación Vin / GND. Destruimos los microcontroladores.Porque:No existe protección de voltaje inverso aplicado a la clavija de conexión Vin. La corriente circulará desde el pin GND del microcontrolador a través del pin 5V, a través del regulador de 5V y Vin. El microcontrolador y el regulador de 5V se destruirán.Método # 5: Aplicar> 5V al conector de 5V PinCómo:Aplicar una tensión de 6V o superior al pin conector de 5V. Se destruirán muchos componentes en el Arduino y esta tensión también puede aparecer en el USB del ordenador.Porque:No hay protección en el pin conector de 5V. Esta tensión está conectado directamente al microcontrolador, a la interfaz del microcontrolador del USB y al regulador de 5V.Método #6: Aplicar > 3.3V al conector 3.3V PinDe la misma forma que el caso anterior pero con una tensión > 3.3V (3.6V)Método #7: Aplicar > 13V al pin ResetCómo:Aplicamos energía > 13V a la clavija del conector de reset. El microcontrolador se dañara.Porque:El conector del pin Reset está directamente conectado a la clavija de reinicio del microcontrolador y tolera hasta 13V. Más de ese voltaje se dañará el dispositivo.En conclusión, ya sabéis cómo destruir Arduino y lo que no tenéis que hacer. Pero como os hemos dicho al principio, no veáis vuestros errores o fallos como algo negativo, sino todo lo contrario. Con ellos habéis aprendido más que con vuestros éxitos.El recurso del diaXOscilo¿Quieres transformar tu PC en un osciloscopio? XOscillo te permite convertirlo.
