Podcasts about 12v

What if students could learn about EVs by building and driving one themselves? Switch Vehicles, a company that combines hands-on education with industry-relevant training, provides that service. Its EV training program enables students and teachers to assemble fully functional electric vehicles.In this episode, Brandon Watt, Marketing Director at Switch Vehicles, and Dan Vincent, lead instructor and retired professor, explain the Switch Lab program. Instead of using emulators or theory alone, students wire, assemble, and test real EV systems. They work on 12V, high-voltage, regenerative braking, and torque response systems – and then get to drive the finished vehicle.The Buzz: www.thebuzzevnews.com

In this video, we dive into the EPA's deregulation plans under Lee Zeldin, exploring how they could impact Jeep Wrangler, Gladiator, and Grand Cherokee owners. Learn about the potential removal of Start-Stop incentives, consumer feedback on its inconvenience, and the future of diesel models like the 3.0 EcoDiesel. We also cover the Trump administration's push to roll back Biden-era emission standards, including the GHG Phase 3 rule for heavy-duty trucks, and what it means for costs and compliance. Plus, a bonus Jeep Gladiator update featuring the Ancel BM200 battery tester for easy 12V battery monitoring!

Pope Francis had become one of the most influential voices on the moral side of climate change. Back in 2015, he released an encyclical called Laudato Si', where he framed environmental issues not just as scientific or political problems, but as deep moral and spiritual ones. He emphasized that climate change affects everyone—but especially the poor and vulnerable who contribute the least to the problem yet suffer the most from its effects.

Kingdom Come: Deliverance 2 kommt ziemlich gut an - sowohl im Technik-Test der Redaktion, als auch bei der Community auf dem heimischen Gaming-PC. Kein Wunder also, dass Fabian und Jan in dieser Woche einen Fokus auf das Mittelalterspektakel mit einer Open World, die im Zweifel einfach nur zum Spazierengehen einlädt, legen. Im Anschluss wird eine Runde Lob an die Community für die Teilnahme am Monster Hunter Wilds Community-Benchmark verteilt. Und am Ende muss es diese Woche natürlich auch noch um Nvidias "Multi Flame Generation" gehen, also erneut kursierende Probleme mit verschmorten 12V-2x6-Kabeln und -Buchsen an der RTX 5090 (FE).

While debugging a non-working bumper car toy for BabyAda, we determined that the vendor, for some reason, provided a 24V DC power adapter when the battery is 12V and should be charged only up to 15V max! Uh-oh, it's time to fix it up. Let's head over to DigiKey to get a new 12V lead-acid battery that is the same size and shape so we can swap it in and recycle the old one.

BabyAda's bumper car toy stopped working after overnight charging - turns out 24V charger + 12V battery = problems. Quick fix: replaced battery with correct one from DigiKey. Pro tip -Always check voltage compatibility!

We got our WLED-friend PCBs (https://blog.adafruit.com/2024/12/02/leftovers-layout-wled-board-revision-a-completed/) and are testing it with various LED grids. First, we tried out a 16x16 NeoPixel grid that runs on 5V. Since that worked well, we're now onto a much bigger 60 x 60 grid - that's 3,600 LEDs! These are some NeoPixel pebble (https://www.adafruit.com/product/6024) netting samples we're also testing at the same time; each one has 20 x 60 pixels and uses 12V power, so it's a good test of the DC pass-through for higher voltages. Since WLED has a limit of 2000 pixels per output, this demo uses the three output ports that are then 'merged' together in memory to make a single large grid. We have more to test soon: the onboard IR receiver, USB PD, I2S microphone, extra I/O pins, and I2C, so watch for those videos as they come together.

This week's EYE ON NPI is the ideal component for your next power supply design, it's Nexperia's NID5100 Ideal Diodes (https://www.digikey.com/en/product-highlight/n/nexperia/nid5100-ideal-diodes) a simple design improvement to Schottky diodes or simple P-FET polarity protection. This small and low-cost component from Nexperia is their first 'ideal diode', and can be used in many low voltage power supply setups to reduce power loss and get you more product life from your battery Diodes, who doesn't love them? (https://en.wikipedia.org/wiki/Diode) You put some P-doped Silicon next to N-doped Silicon (https://en.wikipedia.org/wiki/P%E2%80%93n_junction) and before you know it, you have accidentally semiconductored! Make them big enough and you can even solve global warming (https://en.wikipedia.org/wiki/Photovoltaics) We use diodes all the time, and they're particularly useful for power supplies since they make sure current only goes one way. We often use them in front of a DC jack, between the power input and the circuitry: this keep the voltage polarity positive with respect to ground, since most modern microelectronic components want between 3-24VDC. Or, as an OR: either battery or USB power are hot-swapped so that whichever gives the highest voltage will run the downstream electronics - see our Trinket M0 schematic for a simple example (https://learn.adafruit.com/adafruit-trinket-m0-circuitpython-arduino/downloads) When we first started electronics we'd use the classic 1N4001 (https://www.digikey.com/short/d8jn3f9v) - this low cost diode can handle high currents and about 1A continuous, with about 1-2V forward drop. When we did +12V power to an LM7805 (https://www.digikey.com/short/7vv3zc1d) this was fine, we have 5V to burn. Sometimes if we were feeling fancy we'd use a Schottky diode like the 1N5817 (https://www.digikey.com/short/8fntvnrv) which has about 0.7V drop, these are often used for boost or buck converters where you don't want to lose efficiency in your free-wheeling diode switch. But when using a 3.7V nominal voltage lipoly battery into a 3.3V regulator, we have to dial it down - even 0.7V is too high - so we'd often reach for a lower-drop Schottky like the Nexperia PMEG2010 (https://www.digikey.com/en/products/detail/nexperia-usa-inc/PMEG2010ER-115/2119861). We still use this part a lot, but we could do better with an Ideal Diode like the NID5100! (https://www.digikey.com/short/4td40hmh) Ideal diodes are as close as possible to the platonic ideal (https://en.wikipedia.org/wiki/Theory_of_forms#Ideal_state) of a diode as possible: Forward conduction only, with zero reverse conduction, and minimal voltage drop. Sometimes folks try to mimic this with a reversed P-FET and yes this will give minimal forward voltage drop for polarity protection (http://www.youtube.com/watch?v=IrB-FPcv1Dc), but it has 'infinite' reverse leakage instead of close-to-zero. The NID5100 is more complex, with additional circuitry for driving the P-FET. It can be used either as a polarity protection for a DC or battery input where there's risk of the voltage being inverted, or as an OR-ing voltage select. Compared to a Schottky, it can handle 1.5A continuous - most basic Schottky's are 1A - and with a forward voltage drop of only 50mV at 0.1A. The package size and price is also very comparable to a SOT323 diode, in an easy-to-place TSSOP6 and under 10 cents in reel quantity. We also like the extra pins like an Enable, so it can also act as an on/off switch, and a Status pin that lets you know when the diode is conducting: this can be used to detect which power supply is active in an OR setup. Does the Nexperia NID5100 (https://www.digikey.com/short/4td40hmh) sound like the ideal solution to reduce heat and power loss in your next product? Yes! And it's in stock right now at DigiKey for immediate shipment. Order today and you'll receive your components faster than a diode switching time, for integration into your BOM by tomorrow afternoon.

These cafe lights come with WS2811s inside. Power them with 12V, and you can send them 5V NeoPixel signals to light up individual 3 RGB LEDs inside for a nice, bright outdoor look. They're weatherproof and even come with a weatherproof connector, so they'll survive outdoor installation. They'll work great in Arduino, CircuitPython, or WLED.

Aldrig har väl färska inflationssiffror eller Riksbankens penningpolitiska möten varit så intressanta som nu? Vilket ju inte är särskilt konstigt då vi är många som har haft det tufft ekonomiskt de senaste åren. Men varför är riksbanken så mån om att hålla inflationen på just 2% och vad skulle hända om de inte hade en styrränta att hålla oss i schack med? Det svarar Lars Heikensten på som är nationalekonom och tidigare riksbankschef.

Hi. I'm John VK4JPM with a reminder from the Darling Downs Radio Club about tomorrow night's tech meeting. Monday 9 September is the second Monday of the month and means we gather at the Toowoomba Library. The theme of this month's session is "How to get control of EVERYTHING in your shack", which you can do using easily available home automation technology. We'll get you across some of the very powerful apps and extremely cheap technology that can help you run your shack, control your antenna farm, and manage your ham cave and workshop. OK, the details again: we meet tomorrow night, Monday 9 September at the Toowoomba Library from 1900 - that's 7 PM. Tons of free well-lit, secure under-cover parking. The meeting is open to members and guests; there's no charge, and we'd love you to join us for a natter and a cuppa. Check out all the detail, and upcoming club events, at the website: www.ddrci.org.au. www.ddrci.org.au. You can also find us via the WIA website, or just search for Darling Downs Radio Club from your favourite search engine. 73 from John VK4JPM Hello, I'm Geoff Emery, VK4ZPP, and I've been thinking. It was distracting hearing the squelch breaking on the 2m repeater on 146.800Mhz and then faintly came a female voice. It was obvious that ducting was having its fun with us, along the S.E. coast of Queensland but it wasn't until I read a post that the full impact became obvious. From the Gold Coast to various parts of the coast signals from New Caledonia were being received. It is over 25 years since I heard this and made a successful contact so I live in hopes that this summer season we can experience international VHF contacts with better results. Sadly, I had a poor experience on social media during the past week. A group popped up in the “you may be interested category” and as I have been seeking to finish putting together a small set-up for camping and portable radio operation, I thought it worth joining. This group is obviously an eclectic one of lay and tradie types devoted to low voltage use and it suited me to join to observe what others had found worked for them. After approval by the administrators, I had the opportunity to post an introduction as to why I had joined. Sadly this is when the first response was a very generous putdown and questioned my knowledge and why I would want to join this group. OK, we have all had experience of keyboard warrior types on the internet but it was plainly obvious from the tenor of this post that the writer was also a radio amateur. I tried a couple of times to correct some of the falsehoods that were directed at me and the insulting tenor of the replies continued. As I had just joined this group, the rules were fresh in my mind and I pointed out to this person that they had breached the group rules and left to go about my other business. The next day, I went back to this site to check if there had been more responses only to find that the administrators had monitored or been alerted to this incident. The attacking comments had been deleted from my post and there remained some courteous and considered replies from other group members. My concern is not for the insults directed at me but the very serious effects that this behaviour could have on members of that group when considering amateur radio and its participants. I don't want to sound precious or prissy but how we present as hams in public naturally reflects on our whole community. This group is enjoying learning about 12V use and installations so they already have an affinity with electricity. Perhaps some of them may want to take that interest into wider fields of interest and I would hate for them to be influenced away from amateur radio by one person acting badly. I'm Geoff Emery VK4ZPP and that's what I think….how about you?

Welcome to the ultimate guide on Harbor Freight's MADDOX 12V, 125 PSI High-Performance Inflator If you've ever found yourself stranded with a flat tire, underinflated sports gear, or any other air-filled emergency, this video is for you. 

This week on the Great Search, we saw someone on social media talking about repairing an old device that has a 'split' supply with multiple voltages. (https://twitter.com/dorksince93/status/1779346977861615666) Usually your AC-DC adapter converts 110~220VAC into 12VDC. But sometimes you need +12V, -12V, plus maybe a 5V for good measure. And sometimes the connector ends up being a DIN because it has to support so many different voltages! (https://twitter.com/dorksince93/status/1779346977861615666/photo/1) Let's show how we can find this kind of device, as well as a matching cord (https://www.digikey.com/short/n8z3h7nn) on DigiKey so that we can resuscitate some old devices and keep them out of the landfill!

A short snippet from our latest episode where we gave Duggo free reign to ask Ronny any and every question he had about the 12V battery system... Full episode out Friday's.Music by The Southern River Band. Shelter is born and brewed in Busselton, Western Australia. Hosted on Acast. See acast.com/privacy for more information.

we're often working with 'true analog' LED strips (https://www.adafruit.com/search?q=analog+LED), that have 1-3 channels of RGB or White LEDs. and controlling these takes a bit of wiring since they almost always need 12VDC and driver FETs. to make our lives easier, and maybe even some customer's too, here's a STEMMA board (https://www.adafruit.com/product/3893) that can convert a NeoPixel signal using a WS2811F to three AO3406 N-channel FETs (https://www.digikey.com/short/438tn2hb) that are high efficiency and can sink a chunk of current. there's a 3-channel 74LVC3G14 (https://www.digikey.com/short/tqq3tm3m) inverter in between to convert the WS2811 output signal which is open drain, to the NFETs. 5 terminal block ports allow for easy wiring of the +12V, ground, and RGB common-anode channels. unfortunately the WS2811 does not support 4-channel so this won't work for RGBW strips...but there's a lot of times folks need 1 or 3 channels!

This week's EYE ON NPI is a part of a balanced breakfast, wait no we mean a balanced battery pack! It's STMicroelectronics' AEK-POW-BMS63EN Battery Management System Module (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/aek-pow-bms63en-battery-management-system-module) featuring the L9963E automotive multicell battery monitoring and balancing IC (https://www.digikey.com/short/q4jw21t1). This chip brings automotive-grade battery management to any product designer, at a great price, so you can keep your batteries monitored and balanced for a safe and long usage life. All cars have batteries, and if you have a internal combustion engine car, you're probably familiar with the 12V lead acid battery (https://www.diehard.com/vehicle-batteries/) that needs replacing every 5-10 years, these batteries do not power the moving car itself, just the lights, stereo, electrical system and the spark plugs needed to get the engine running. These batteries are pretty simple, there are two big lugs, a ground and a +12V, inside is 6 series Lead Acid cells, of 2V nominal each. The battery is charged by the engine, and while you don't want to over or under-charge lead-acid batteries are pretty forgiving. In EV electric vehicles, the batteries have to have much higher energy density (https://en.wikipedia.org/wiki/Energy_density) so they use Lithium Ion cells, often '18650' cylindrical cells. These are connected in long series strings, to provide high voltages and then parallelized to give high currents. The same batteries are also used in e-scooters, e-skateboards and other micro-mobility devices, they're very low cost, and packs are easy to make. BUT, Lithium-based batteries, as part of the high energy density, have a lower life and are more sensitive to charge and discharge cycles. One of the things we have to worry about is keeping the batteries balanced. That means that we have to monitor each cell in the string carefully to make sure the state of charge matches the rest. The ST L9963E does this in two ways (https://www.digikey.com/short/q4jw21t1), first is per-cell voltage monitoring, and also per-string current monitoring. Once each cell's state of charge is known, internal or external FETs can be used to shunt current from each cell during the charge cycle, with the goal of bringing the cells back into balance at the cost of charge rate because now we're going to charge every cell as slow as the 'worst' cell. However, this keeps the system safe from overcharging, and is a lot less expensive/complex than active balancing. Since this chip is fairly complex, having a ready-to-go eval board that is already set up with the isolated SPI interface is a worthy investment. You can get started fast and just integrate the AEK-POW-BMS63EN directly into your prototype while you work out your battery management system. The board has USB-like ports on either side but these are actually two-wire isolated SPI, which protects your low-voltage microcontroller or computer from possibly getting zapped by the 48V+ battery. You can use USB A-A cables, since the pinout will work fine, but just be aware you can't plug it into your computer. To connect the opposite side to your micro, you'll also need to pick up a de-isolator AEK-COM-ISOSPI1 (https://www.digikey.com/en/products/detail/stmicroelectronics/AEK-COM-ISOSPI1/19721659). Finally you'll need to write the SPI interface library for managing the battery. We found one published L9963E library that might get you started (https://github.com/squadracorsepolito/L9963E_lib) - written by the Squadra Corse student Formula SAE teams. (https://squadracorsepolito.com/) If you have a project with large batteries and you want an automotive-grade battery management system, the L9963E automotive multicell battery monitoring and balancing IC (https://www.digikey.com/short/q4jw21t1) and matching Evaluation Board (https://www.digikey.com/short/c00jq224) will make it easy to get started. And best of all, both are in stock right now for purchase at DigiKey! Place your order today and your order will ship in moments, so you can get started with battery management by tomorrow afternoon.

Do you need your radio to have USB-C charge capability? With Yaesu HTs, maybe not - all of the Yaesu radios I feature in this video are chargeable directly from a 12V source, most of them with the same plug, which is interchangeable.

we designed this TPS61040 board (https://www.digikey.com/en/products/detail/texas-instruments/TPS61040DBVR/454263) like a year ago and messed up the BOM on the first run so that it had 100 ohm resistors instead of 100K for the voltage-setting divider. woops! and then it sorta sat on the "to fix" pile for a long time. but...new year, new us! time to fix and get back into production. the tester is a Metro 328 (https://www.adafruit.com/product/50), it turns on and off a 120 ohm load to verify the 12V output can source the current specified. a resistor divider goes from the output to a analog input. beep! its good to go :) Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

Honk! Honk! This week's EYE ON NPI is jazzy, be-dazzly, and sure-to-get-your-attention-y: it's CUI Devices' Illuminated Buzzers (https://www.digikey.com/en/product-highlight/c/cui-devices/illuminated-buzzers), a set of incredibly loud audio indicators that also have built-in LEDs that light up! What a great way to quickly turn an existing design into an accessible, multi-sensory alarm system without having to redesign the enclosure or PCB. These are very loud buzzers, good for industrial equipment - with a range of 83 to 100 dB, loud enough to alert in an office or factory. The LEDs are also nice and bright, for good indoor visibility. There are three sizes/shapes available. The smallest is the CLI-1375 PCB-mount design (https://www.digikey.com/short/m4zc8d3z) with 13mm diameter body, which is the same shape as many PC-pin buzzers. When powered with 6 to 15V it emits a piercing 83 dB, 4 KHz square wave and the inner LEDs light up. You can get 4 different shades of translucent plastic: red, yellow, green and blue. Note you aren't expected to provide a square wave: there's an internal wave generator. There's two versions for the CLI-1375 buzzer, one has a steady tone and LED light, the other has 1 Hz-ish modulation for both the LEDs and beep. The CLI-3224 medium size is 32mm diameter (https://www.digikey.com/short/1zwrvdf1) is a nice panel mount version with 8 SMT LEDs, four color options, and a shape that is evocative of arcade buttons. This version has spade connectors for power, and can be powered from 3 to 15 VDC. It will emit a 95 dB 3 KHz tone at the 12V rated power. Unlike the PCB-mount design, this one doesn't have a 'pulsing' version. Finally, the CLI-3623 large size is 36mm diameter (https://www.digikey.com/short/4tnpp4fz) and is also panel mount, but with a flatter top. It also has 8 SMT LEDs, and four colors. Like the CLI-3224, 3-15VDC power is provided via spade lugs. Volume is also 95 dB at 12VDC, the tone frequency is 3.5KHz. All 16 versions of 4 types, and 4 colors of CUI Devices' Illuminated Buzzers (https://www.digikey.com/short/b790m8vw) are in stock right now at DigiKey for immediate shipment. So if you order today, DigiKey will get the alarm to get your order out the door ASAP, and you can get beepy and blinky instantly with any configuration you desire by tomorrow afternoon.

This weeks EYE ON NPI is a real throwback for us, it's the Orion Fans' ML2010 Mini-lab (https://www.digikey.com/en/product-highlight/o/orion-fans/ml2010-mini-lab), a portable engineering toolkit built into a suitcase for easy transport. This Mini-lab reminds us of the MIT Nerd-Kit used in digital and and analog design classes that require construction of circuit labs (http://web.mit.edu/6.111/www/project-photos/s98-projects-photos/s98projects.html). These suitcases were durable ...and super heavy! Thankfully we did not have to carry them back and forth to home each day - there were lockers in the lab. Many a digital-lab student wished we could keep the kits after finishing the course but sadly nerd-kits were not for sale - and we shudder to think what fate would befall us if we neglected to return them. Which is why this NPI caught my eye...finally I can have my very own nerd-kit thanks to Orion Fans and Knight Electronic Products. This silver suitcase contains many common analog and digital-logic tools to help prototype projects on a breadboard: Breadboard Power supplies Function generator stimulus Sweep ramp generator stimulus Pulse generator stimulus Protoboard I/O ports Switches Indicators Heavy-duty carrying case The solderless breadboarding area is made of three 630-point solderless breadboards (https://www.digikey.com/en/products/filter/solderless-breadboards/638), so large circuits with many breakout and dev board PCBs can be laid out. There's also a separate perf-board area (https://www.digikey.com/en/products/filter/prototype-boards-perforated/636?s=N4IgTCBcDaIA4FMBOAzABAIwPYEMkBMQBdAXyA) for higher-frequency work that could be affected by the breadboard capacitance, or when you want more mechanical stability. The perf-board snaps out when your project is done. The power supplies are where analog hackers are going to be happy, particularly folks who are designing exotic motor/power systems or audio/synthesizers: it has both +5, -5, +12, and -12V at 1 Amp output split supplies, and isolated-ground +18 and -18V at 1 Amp outputs, all with 0.1% line/load regulation and short circuit protection. For AC supply design - rare to find, so if you need it this will be a blessing - there's 15VAC center tapped that can supply 500mA. The power supplies are fused, and controlled by a large on/off rocker. Another great feature for analog hackers: there's also a full-featured function generator (https://www.digikey.com/en/products/filter/function-generators/630), with sine/square/triangle out - up to 18Vpp and +-10V DC offset with selectable decade ranges from 1Hz to 1MHz, and low distortion under 100KHz. There's inputs for FM, AM and sweep modulation (https://en.wikipedia.org/wiki/Modulation), for low-frequency RF experimentation. There's also a plethora of connectors and switches so you don't have to figure out how to panel mount connectors or work out mechanical stabilization. For toggle switches, there are 2x SPDT momentary toggles, 2 x SPDT toggles, and 8x logic level toggle switches. D-Sub connectors also: DE-9 and DE-25 in plug and socket format. For connecting to other test equipment, 3x BNCs. And for input/output, 8x red LEDs, a 1K pot, a 100K pot, and an 8 ohm 1/4 W speaker. The Orion Fans' Mini-lab toolkit (https://www.digikey.com/short/bdhcv3pw) would make a great resource at a lab, workshop or classroom. It's hefty and durable but that also means it'll last a long time. It's an excellent step up from just cobbling together parts that can come loose, and you can put it away safely between hacking sessions without the risk of someone 'borrowing' a part! And best of all, it's in stock right now at DigiKey for immediate shipment! Order today and you can be prototyping in style on your very own Mini-Lab by tomorrow afternoon.

This week's EYE ON NPI stands alone as a fantastic new solution for high power charging of large battery packs and also power boosting from battery to system: it's ADI/Maxim's MAX77789 Standalone 3.15A Charger (https://www.digikey.com/en/product-highlight/a/analog-devices/max77789-standalone-3-15a-charger), an all-in-one power management IC that lets you ditch DC power plugs and simplifies your BOM, at an excellent price. We'll also be covering the MAX77787 (https://www.digikey.com/short/wzv7095b) which is the fraternal-twin-sister product: using I2C instead of resistor settings for configuration. We've been covering USB Type C PD sinks and supplies for about a year here on EYE ON NPI & The Great Search, they're an excellent way to ditch those DC barrel jack power supplies (https://learn.adafruit.com/usb-pd-hacks/) and allow folks to use a single connector and standard power supply (https://www.youtube.com/watch?v=C90UnNAlCFQ) for various voltages, from 5V-20V at up to 5A. There's plenty of chips that will connect to a PD source and negotiate that voltage for you (https://www.youtube.com/watch?v=yQea9IEmf28) but now we can start to take advantage of USB PD for battery charging as well! This week's dynamic duo does pretty much everything for battery management. As devices get more complex, and battery cost goes down, the packs included in products are getting bigger. If you're trying to charge a 5Ah battery at standard 5V/1A rates, it will take at least 5-8 hours to do so, when folks really want 1-2 hour charge rates. The MAX77789 and MAX77787 have a buck converter that will deliver up to 3A to the battery for 3x faster charging. But, if you try to draw 3A from a USB 5V power cable, that built-in resistance will cause a voltage droop - remember we need at least 4.5V to have the headroom for charging up to 4.2V or 4.35V Lithium batteries. Thus, these chips use USB PD (https://learn.adafruit.com/understanding-usb-type-c-cable-types-pitfalls-and-more) to request higher voltages when available: 9V or 12V means that we can draw less current to get the same amount of power, which means less resistance loss over the cabling. For pre-C chargers, such as Samsung or Apple or Quick Charge (https://learn.adafruit.com/understanding-usb-type-c-cable-types-pitfalls-and-more) the USB D+/D- pins are used. In such cases where you want to have the data pins available for USB data/sync, you'll need something like the MAX20334 (https://www.digikey.com/short/p8b23vf3) data line switch to flip the pins back to your MCU. The MAX77789 uses resistors on the IFAST, ISET and INLIM lines to set the charge rate, timeout, and pack float voltage, the MAX77787 uses I2C. Both have a couple configuration pins, and LEDs for status monitoring. Both have the ability to also be turned into a boost converter - you can't use both charging and boosting at the same time, but since you can use the SYS voltage when connected to USB, you'll have at least 5V either way. The booster is fixed to 5.1V output. On the '89 the boost is enabled by GPIO, the '87 enables it over I2C. Both chips are available in 0.4mm pitch BGA - which means pad-in-via and multi-layer boards in order to pass the inner configuration traces out. Many of the traces are tripled-or-quadrupled to provide the current carrying capability of 3A charge and 6A peak discharge. An eval board is also available (https://www.digikey.com/short/4dc80hwz) which makes quick verification easy. For the I2C configuration version there's also desktop software to try out various settings - the standalone version has jumpers so you can attach any resistor value. Both the ADI/Maxim MAX77789 (https://www.digikey.com/short/j7zhtj4h) and MAX77787 (https://www.digikey.com/short/wzv7095b) Standalone/I2C 3.15A Chargers are in stock right now at DigiKey for immediate shipment. It's great to see forward momentum in chip design releases now that the shortages have abated: only a year ago we were scrambling for diodes and op-amps and now we have a wealth of great new products to choose from! Order one of these powerful Lithium battery management chips today and you'll have it shipped immediately so that you can start integrating it into your new design by tomorrow afternoon.

This week on the podcast we go over our reviews of the Mountain DisplayPad and MacroPad, Cooler Master MasterLiquid 360 Atmos Liquid CPU Cooler, and HyperX Cloud III Gaming Headset.  We also discuss Newegg's new GPU trade-in program, MSI's new limited edition "Drops", the new 12V-2x6 GPU connector and more!

This week's EYE ON NPI is switching it up, with a look at some high-voltage-capable analog switches - Texas Instruments' TMUX821x Flat RON SPST 4-Channel Switches (https://www.digikey.com/en/product-highlight/t/texas-instruments/tmux821x-flat-ron-spst-4-channel-switches). A simple and effective way to switch and control up to 4 x 100V connections with up to 200mA each from any microcontroller or microcomputer. We carry dozens of different switches (https://www.adafruit.com/category/759), and DigiKey stocks easily 50K different switch configurations (https://www.digikey.com/en/products/result?s=N4IgTCBcDaIM4HcCWAXAxgCxAXQL5A0) from push-buttons (https://www.digikey.com/en/products/filter/pushbutton-switches/199) to toggles (https://www.digikey.com/en/products/filter/toggle-switches/201) but all of these require a person to push the button mechanically, whereas the TMUX series will connect and disconnect based on a separate digital signal, as low as 1.8V and as high as 48V. These are often used for switch audio or video, but are also often used in sensor measurement or test equipment. They're not good for power supply switching, and for digital signals there's often other ways of moving signals around, although they are sometimes used for the data lines of bidirectional digital signaling systems like USB. Like mechanical switches, the TI TMUX family of analog switches are 'bidirectional' (https://www.youtube.com/watch?v=z9GRiYPq7LM) - that means you can pass signal from A to B or from B to A. However, unlike mechanical switches there is no, well, mechanical connection. Instead, the switches are created by putting an N-FET and P-FET back-to-back. This means that there is no switch-bounce (https://en.wikipedia.org/wiki/Switch#Contact_bounce) or contact oxidation (https://en.wikipedia.org/wiki/Electrical_contact). Analog switches are pretty magical, and solve design problems that involve moving an analog signal around without having to hand-build a switch on board, but there are a few things to watch out for when 'modeling' how an analog switch varies from a mechanical one! First up, analog switches have fairly low 'Ron' resistance when the analog switch connection is made - on the order of a few ohms - and that is much higher than a mechanical switch. There is also 'very very high resistance, but not an open-circuit' when the analog switch connection is broken - on the order of a few hundred mega-ohms. (https://www.youtube.com/watch?v=n9EklrCrgH8) And don't forget you will need to have positive and negative power supplies beyond the voltages switched. So, if you are trying to switch 24Vpp signal, that ranges from -12V to +12V, you will need to supply them on the VDD and VSS lines. Also these are not electrically isolated, so add a separate opto/digital isolation (https://www.ti.com/isolation/digital-isolators/overview.html) circuitry if you want to keep your microcontroller fully disconnected from any high voltages. But compared to classic jellybean analog switches like the CD4066 ,(https://www.digikey.com/short/jw44n87t) the TI TMUX series of analog switches have improved circuit protections that will keep you from popping your chips (https://www.youtube.com/watch?v=RTPHjhjUl0E) by accident - especially since this series can be used with up to 100V. Check the datasheet for all details, but highlights include: built in pull-down resistors, protection against over/undervoltage as well as out-of-order voltage application, and latch-up immunity. If you're looking to switch up some analog signals on your next design, check out the Texas Instruments' TMUX821x 4-Channel Analog Switch (https://www.digikey.com/short/r3rhn270) family with 3 different configurations of NO/NC. And all are in stock for immediate shipment from DigiKey! Order tonight and by tomorrow morning you will be switchin' and swatchin' with these low Ron SPST analog switches.

We wrote a driver this week for the HUSB238 USB PD sink chip https://blog.adafruit.com/2022/05/04/plug-n-play-usb-type-c-dummy-pd/ - this IC is neat in that you can either use jumpers (really, resistor selection) to set the desired PD voltage and current ooooor you can use I2C for dynamic querying and setting. we have a wall adapter that can provide almost-all-PD voltages: 5/9/12/15/20 only 18 is skipped. The HUSB plugs into the USB C cable and, over the CC lines, will negotiate the PD request and commands. For example, we can ask what voltages are available and then iterate over the options here: a multimeter displays the output voltage to prove it works! This can be a handy chip for projects where you need a lot more than 5V @ 2A power: this adapter can give up to 20V at 5A - yes 100W over USB C - and you could buck that down to get a toooon of current at 5V or 12V if that's needed. Arduino library and example code is here https://github.com/adafruit/Adafruit_HUSB238 . This is also one of the first shipping boards using an OpenAI ChatGPT assisted library https://chat.openai.com/share/d05c963d-b610-4eef-ad98-05656a33e118 https://chat.openai.com/share/a276ce74-f810-4dba-a324-e9fd1545085f Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ ----------------------------------------- #adafruit #arduino #HUSB238 #opensource #opensourcehardware #USBPD #usbc #powerdelivery #techinnovation #smartchip #electronics #projectpower #voltagecontrol #driverupdate #usbchip #hardwaredevelopment #openai #chatgpt

This week we're working on reviving our old floppy hacking projects by making a dev board that will let us connect to various old-school disk drives to either control or emulate them (https://github.com/adafruit/Adafruit_Floppy). These devices used lots of motors and solenoids to spin and eject the discs, so we will need to be able to provide them with a good amount of current. For 3 1/2" floppy drives, 5 Volts at 1 Amp or so is not unusual, and we expect larger disk drives may need even more power. For the other motors, we'll want to have a 12 V power supply input, so we need to convert 12V to 5V, and at these currents, an LDO like the 1117-series (https://www.digikey.com/short/z8vtf00m) will have to dissipate way more heat than we'd be able to get rid of - that's when a buck converter is a great alternative. Let's find a powerful and affordable converter that can provide 2A or more.

Chris and the kids are remote in Colorado for this episode. While not the usual camping trip, a cabin in Breckenridge this time, the kids have been having a blast playing in the Rockie Mountains. Chris also provides an update on the 12V fridge/freezer that he purchased back in the Spring. Chris also discusses the 4-person Rooftop Tent that he has ordered and is already experiencing the fun of shipping delays.

For our new Metro RP2040 design, we're making sure that the board can be powered by either USB Type C 5V, or DC wall adapters. While it's common to have 5V USB power almost everywhere, DC power is still useful for when you want 12V to also drive a motor or LED strip. In such cases, we'll use a 5.5 / 2.1mm DC jack to allow the most-common-sized plugs to work. These jacks come in a few common configurations, and have different power ratings and usage cases - even though they all look the same! We'll find a few good options and chat about what to look out for. See the chosen part on DigiKey https://www.digikey.com/short/bwwn4pvt Visit the Adafruit shop online - http://www.adafruit.com

Foundations of Amateur Radio The other weekend there was an amateur radio contest on. Not surprising if you realise that's true for most weekends. For a change, I knew about this contest before it started, because I missed out a year ago, so I did the smart thing to add it to my diary with an alert a month out. In this particular contest there's points to be made by being a so-called roving station, that is, one that moves around during the contest and in the past that's how I've participated and had lots of fun. So the die was cast and a plan was concocted. Being a rover meant that I would be outfitting my car with my radio. It's been out of the car for several years, taken out when we had the transmission replaced, and never actually returned. I started making lists of everything I'd need, including learning that you can use a bench top power supply to charge a 12V battery if your trusty charger has let the smoke out. I went hunting for the cable that connects the front of the radio to the back and realised that it was still in the car, so I could cross that off my checklist. I decided for the first time that realistically I could log using paper and save myself the heartache of finding a computer with a suitable battery and matching software, especially since I'd be operating with low power so making a gazillion contacts wasn't going to be a problem. I went to the shops to get some road food, in my case I like to bring water and oatmeal bars which keep me going through the night. One change was that the contest only ran for 24 hours, leaving less time for sleep. I found my portable antenna tuner, plugged everything in, configured the radio for remote tuning, and tested it all on the bench in my shack. In further preparation I packed my food, got a headlamp out, spare batteries, a pen and a spare, a ring binder for logging and my wristwatch to keep track of logging times. The day before the contest I parked the car in the sun, extracted all the cables from behind the backseat, installed the radio, the battery, the head, the suction mount, the microphone, the speaker, the antenna tuner and antenna mount, and got everything where I wanted it. In between rain showers I located the ropes I use to keep the antenna from breaking off the car when I'm driving, set it all up to length after hunting through the garage to find my multi-tap antenna to suit. Strapped that all together to the handhold in the cabin with a Velcro strap and called it a day. The next morning I drove to my first activation location, installed the antenna on the 40m band, turned on the radio, tuned it, and called CQ Contest. Made my first contact about six minutes after I started. I was excited. Drove to the next location, made the next contact six minutes later. On a roll I drove to my third spot, where things came unstuck. I spent the next two hours getting nothing. I changed both location and band, setting the antenna to 15m and after initially tuning once I couldn't get it to tune again. I spent an hour trying. Given that I wasn't far from home, I went back for a break and to pick up one piece of equipment that I should have packed when I started, my antenna analyser. I tested the antenna and for reasons I still don't understand, it was only resonant on 19 MHz, not much good if you're trying to tune somewhere on 21 MHz. I moved back to my first spot and changed to the 10m band. Three hours to the minute after my second contact, I made another one, this one outside the state. By this time it had been raining steadily for four hours, despite a forecast of little or no rain. The car was stuffy, no way to open the window and stay dry, no contacts, no fun. I asked myself why I was doing this and decided that I'd learnt a valuable lesson and packed up and went home. I did go out later in the afternoon to provide some moral support to a friend who had made double the three contacts I'd made, but by dusk we had both had enough. My lesson for this week? Test the antenna before you go out and bring your analyser. I must add that I've been contesting for years and I've always packed the analyser but never ever needed it. This time I didn't and Murphy let me know that anything that can happen, will. It might sound like a dejected wet cat story, but I learnt a valuable lesson and now I've got another challenge, to discover just why my trusty antenna stopped working. If I do find out I'll let you know. What unexpected lessons have you learnt of late? I'm Onno VK6FLAB

This weekend we whipped up a quick FUSB302 (https://www.digikey.com/en/products/detail/onsemi/FUSB302MPX/5844455) breakout that will allow USB Type C sink power negotiation. Basically, we can plug into a USB hub or wall wart that can provide up to 20V and request that much voltage. This could be really handy for audio or robotics projects that need 9V, 12V, 15V or 20V without the fuss of finding a matching DC adapter. Now that we've got the chip, the datasheet lets us know that we need a separate, external 3.3V-ish regulator to supply power to the chip. Let's go looking for an LDO that can handle 5V-20V in, and provide 3.3V and at least 100mA, along the way we'll also check that we have voltage-rated components and also chat about LDO versus buck converters for this use case. See the chosen chip on Digi-Key at https://www.digikey.com/short/j3jtz4zm

This week we list the content our listeners use to show off their systems whether it be for music listening or movie watching. Also, Sony announced five new receivers that we discuss. And as usual, we read your emails and go over the week's news. News: Super Bowl LVII will screen in 4K and Dolby Vision, but there's a catch Google Plans To Punch Up ‘NFL Sunday Ticket' With New Features Klipsch Expands High-Resolution Powered Speaker Series QD-OLED TV Prices Could Get Cheaper As Samsung Puts Production In Overdrive Sonos' next speakers will be called the Era 300 and Era 100 Listener Recommended Music and Movie Demo Material Music JR - provided the following Spotify Playlist for Music Demos Dan - Marcus Miller: Blast (from the album Marcus) Blast Stan - Daddy's Gonna Pay For Your Crashed Car (U2) & the first three minutes, and Dear Prudence (Beatles) Brian Donald Fagen – The Nightfly – I.G.Y.

Fleetwood Mac - Tusk (Bass) Rush - YYZ This instrumental track will put any speaker to the test. This is a very fast paced song with a lot of stereo testing as instruments move from one speaker to another (helps in speaker placing) and its fast. Chris Issak - Baby Did a very bad thing - he has an amazing voice and he can go from deep to very high Mark - Chuck Mangione - Feels So Good Poco - Heart of the Night Poco - Crazy Love From the Tommy Bolin album Private Eyes, Bustin' Out For Rosey, Sweet Burgundy, Post Toastee Bill - here's a track I use to show off my subs. It was recorded by the Yellowjackets (Galileo for Jaco) as a tribute to Jack Pastorius in the 80s so it has that digitally produced sound. I've had grown men giggle like a kid at about a minute in. Enrique -  Hans Zimmer: Live in Prague Movies DJ - District 9 start at 12:15 and at 12:24 the engine shuts off and you can feel it. JR - Ride of the Rohiorrim scene in The Return of the King (Youtube Clip in 4K with Atmos of this scene) Brian Blade Runner 2049 – Intro Scene Gemini Man – Intro Scene (Dolby Vision 4K60) Mad Max: Fury Road – Intro Scene Ready Player One – Race Scene Midway – Pearl Harbor Attack Scene Top Gun: Maverick – Mach 10 Scene Top Gun: Maverick – 2 Minutes 15 seconds Trial Run Scene Curt - The race scene from “Ready Player One” (Atmos!), train wreck scene from “Super 8” (not Atmos or DTSX, but awesome surround cacophony) John - the end of John Wick when they are in the rain and talking. Also Aquaman the fight sequence about a third of the way in the Italian village.  Mark - Ready Player One, the race scene early in the movie, Dune, around 2 hours into the movie they place the devices to lure the worms, the bass is insane with that, The Dark Knight, when Batman is in the batcave and he's test firing a big gun, crazy bass there too Enrique - Maverick (of course), Mad Max, Blade Runner 2049 Sony Electronics Launches new ES 8K AV Receiver Lineup Sony Electronics Inc. announced its newest addition to the brand's AV receiver line. These receivers are the first from Sony to feature 8K and 4K/120 support as well as Sony's 360 Spatial Sound Mapping technology. These receivers were tuned by Sony engineers to provide the most immersive home theater experience yet. The new ES line features four new models built mainly for custom installation.  Additionally, the STR-AN1000 receiver is created for consumers looking to upgrade their current home theater system. Full Press Release Here… STR-AN1000 - 7.2 Channel 8K A/V Receiver (Pre-Order for $899.99) 7.2-channel A/V Receiver (165 W 6 ohms, 1 kHz, 1ch, THD 0.9%) 8K & 4K/120Hz HDMI Connectivity with HDMI 2.1 support (6-in/2-out) Supports Dolby Atmos® & DTS:X® object-based sound decoding Immersive audio with Digital Cinema Auto Calibration IX and 360 Spatial Sound Mapping  What is 360 Spatial Sound Mapping By utilizing the positional information measured by Sony's Digital Cinema Auto Calibration IX (D.C.A.C. IX), multiple phantom speakers are generated all around the room so cinema lovers can experience every breath, step, and word as if inside the film. D.C.A.C. IX, the latest auto-calibration technology developed by Sony, can correct the distance, angle, sound pressure and frequency response of each speaker by measuring the speaker placement in 3D using the supplied calibration microphone. This works alongside Auto Phase Matching which aligns the phase of different speakers. This means users can compensate for challenging speaker placement, delay or phase shift and feel fully immersed in a movie. Additionally, enjoy music the way the artists truly intended with High-Resolution Audio for crystal clear precision. The ES series and STR-AN1000 also supports DSD (Direct Stream Digital) native playback, with no conversion involved so DSD content can be fully enjoyed without losing any of the original quality. When connected to a BRAVIA XR TV with Acoustic Center Sync, the ES series and STR-AN1000 combine audio from the TV with the audio from the center speaker to create an incredible sound-from-screen experience. Dialogue will appear to come directly from the characters on the screen creating a much more immersive experience. The ES Series models are available for presale at Sony Electronics.
