This week's EYE ON NPI is on the right traq, ready to attaq, and gets no flaq: it's the Digilent USB-2001-TC Single Channel Thermocouple Measurement Device, otherwise known as a single-channel DAQ! (https://www.digikey.com/en/product-highlight/d/digilent/usb-2001-tc-single-channel-thermocouple-measurement-device) These rhymes may get me some flaq, but we can't help it, our lips smaq when we see a good DAQ. And this one is deliciously small and single-purpose. We wish we had one of these a few weeks ago when we wanted to check our reflow oven to calibrate the temperature curve! While we are featuring this particular DAQ board that is good for high temperature measurements via a thermocouple, there's a whole family of boards from Digilent/NI (https://www.digikey.com/en/products/filter/data-acquisition-daq/1017?s=N4IgTCBcDaICIEsDmCA2BTAdgFwAS4FcBnAIxAF0BfIA) All manufactured and supported by MCC (https://www.mccdaq.com/) - the OEM for this series. The others are a mix of Ethernet, Raspberry Pi or USB controlled ADCs & DACs (https://www.mccdaq.com/data-acquisition/low-cost-daq) with 12 to 24 bit resolution, and up to 500 kS/s. The USB DAQ board does not come with a thermocouple itself, you'll need to get a standard K, J, etc. type (https://www.digikey.com/en/products/filter/temperature-sensors-thermocouples-temperature-probes/513) and also have it with a mini thermocouple plug which is available on Digi-Key if you are getting bare thermocouple wires (https://www.digikey.com/short/9hbfrwht). The thermocouple wire can come on huge spools if desired: spot weld one end that will be attached to the hot thing being measured, and then screw the other ends into the mini plug. Inside is Silabs C8051F343 (https://www.digikey.com/en/products/detail/silicon-labs/C8051F343-GQ/990818), Analog Devices ADUM5401 (https://www.digikey.com/en/products/detail/analog-devices-inc/ADUM5401ARWZ-RL/1873647) isolator, and an AD7785 (https://www.digikey.com/en/products/detail/analog-devices-inc/AD7785BRUZ-REEL/1644783) 20-bit ADC. Data can be captured using the DAQami software available for download on Windows (https://www.mccdaq.com/daq-software/DAQami.aspx) although it seems like you can also interface through the hardware using an API or Python (https://www.mccdaq.com/MCC-Software.aspx). Of course, since its a Digilent / National Instruments product, it's also fully supported within LabVIEW. (https://www.mccdaq.com/daq-software/universal-library-extensions-lv.aspx) While normally we're happy to talk about individual interface chips for DAC/ADC/Thermocouple interfacing (https://blog.adafruit.com/?s=%23eyeonnpi+temperature), and there's tons of Adafruit guides on how to DIY this kind of data acquisition (https://learn.adafruit.com/search?q=thermocouple), it's pretty nice to have a ready-to-go USB device that streams data without having to open up an IDE or write any code at all. Particularly for automations where the data has to go into a computer anyways, it can save a lot of time to now cobble together your own setup. The Digilent USB-2001-TC Single Channel Thermocouple Measurement Device (https://www.digikey.com/short/23v0hp90) and other Digilent/MCC DAQs (https://www.digikey.com/en/products/filter/data-acquisition-daq/1017?s=N4IgTCBcDaICIEsDmCA2BTAdgFwAS4FcBnAIxAF0BfIA) are stocked by Digi-Key! They sold out while writing this EYE ON NPI, but they'll have more soon, so sign up to be notified by email when they come back in stock.

This week's EYE ON NPI is ready to be tested - it's a super powerful piece of test equipment from Digilent - we are happy to feature the Digilent Analog Discovery Pro 3000 Series (https://www.digikey.com/en/product-highlight/d/digilent/analog-discovery-pro-3000-series). The Analog Discovery Pro 3000 (which we will shorten to ADP3000) is a huge upgrade from the EYE ON NPI we had last year with Digilent's Digital Discovery pod (https://blog.adafruit.com/2020/09/03/eye-on-npi-digilent-digital-discovery-eyeonnpi-digikey-digikey-digilentinc-adafruit/). That product was a small digital logic analyzer, great for doing firmware debugging with up to 32 channels of 200 MS/s data capture and lots of built-in bus decoding. To match with the Digital Discovery, Digilent also came out with the Analog Discovery 2 (https://www.adafruit.com/product/4652) with two analog input channels of 14-bit, 100MS/s, 30MHz ADC and 16-channel logic analyzer. The Analog Discovery 2 is a great student/maker/beginner mixed-signal tool, and compact enough that you can fit it into your laptop bag for analysis anywhere. But if you want something that is comparable to a 'real' scope, you'll find that you'll want something that can take real scope probes and BNC output for those high speed signal generations. That's why there's now the ADP3000 (https://www.digikey.com/en/product-highlight/d/digilent/analog-discovery-pro-3000-series) - the 3000 means its 1500x 'more extra' than the Analog Discovery 2? Which gives benchtop-ruggedness to a digital USB scope. The ADP3000 series is a 'little bit of everything': Two or four analog inputs with 100MS/s sample rate, 50 MHz bandwidth, 14-bit, +-25V input 16-channel logic analyzer and waveform pattern generator, 1.8 to 5V input, 125 MS/s sample rate Two analog waveform outputs, +-5V, 14-bit, 15MHz bandwidth Now, to be completely fair - this isn't going to replace a benchtop scope. Even my trusty old Tek TDS2014 (https://www.tek.com/oscilloscope/tds2000-digital-storage-oscilloscope), bought 15 years ago, has 1 GS/s and 100 MHz sample rate. And, personally, I still really like twiddling physical knobs when debugging a circuit. So we think that while it could be used as a benchtop toolkit, the ADP3000 isn't designed for that. Instead where we think this tool would really shine is automation or test engineering, where components or setups need to be analyzed or as part of a integration test. That's because Digilent is a wholly-owned subsidiary of National Instruments (https://www.ni.com) who make LabVIEW (https://www.ni.com/en-us/shop/labview.html) an extremely-popular lab/data capture/analysis program. So you know that there's going to be excellent integration, with the Digilent tools getting "First Class" support in LabVIEW. Having seen physicists/biologists/mech e's struggle with how to automate their experiments, this tool would work very nicely in a graduate or company lab. One feature that really stands out for the ADP3000 is that, yes, you can plug it into a computer via USB like you'd expect to capture data on a host PCB, but you can also log in directly into the scope in "Linux Mode". (https://reference.digilentinc.com/test-and-measurement/analog-discovery-pro-3x50/linux-mode) Not surprisingly, this scope runs embedded Linux, that's how it can do stuff like have USB host and Ethernet. But even with Ethernet, there's always the risk of bandwidth or dropped packets. What if you want to get some large data capture going, where you don't want to be restricted by USB? Or if you wanted to connect some additional hardware? We like that Digilent opened up this capability - most test equipment companies would not be excited to let the user log into the device itself and mess around! For scientists and automation and test engineers, this is a very promising tool - and you can pick up one from Digi-Key for immediate shipment right now! There are four 'versions' of this product (https://www.digikey.com/en/products/result?s=N4IgjCBcoLQCxVAYygMwIYBsDOBTANCAG4B2aWehA9lANogCcYADAMwDsIAuoQA4AuUECAC%2BYoA): you can get 2 or 4 analog input and with or without probes. For many uses, ADP3250 2-input version without probes will do a fine job (https://www.digikey.com/short/vmvw4mv3) but check out the other options before checking out. Order today and you can be automating your data acquisition by tomorrow. See on Digi-Key at https://www.digikey.com/short/vmvw4mv3 See Digilent's video at https://www.youtube.com/watch?v=-lMlnb6_Kdw

They've come a LONG way since I started the protocol spec doc a year or so ago.  Provided a couple minor updates in a pull-request, mostly around Crypto protocols.  I have a couple MD380s that I intend to use for M17 hacking. Haven't done anything yet though. Another Field Day, another single episode working on my Contest Station Audio Interface Thingamajig. Debating between two designs: Single unified device, one board with all cables going in and out, all mixer controls in a single place. Distributed devices, with an RJ-45 bus connecting them. Puts controls nearer to the operators/radios, but is more complex.  Allows for further expansion. Playing a bit with my shiny new toy: Flex6400. Book recommendation: The Cuckoo's Egg, Cliff Stoll, K7TA. Not ham radio related, but I suspect will be of interest to hams.

Final score: 2172 points! (but it's totally not a contest.) Had a great turn out! About 12 people total, 7 active hams who played with the radios at least a bit. Ran entirely on solar power, only spun up the generator for a couple minutes to make sure it worked, and show another person how (it's mod'd for Propane.)  2 stations, 100W both, using nothing but solar. I'm really proud of that. SSB station: FT-920, on an EFHW, cut for 40m (so resonates on 40/20/15/10m), but added a loading coil and stub to add 80m. It worked really well, but required more tuning at the radio than I anticipated. The loading coil was 13 turns of antenna wire around an FT140-43 (which should have been about 110uH, except that it totally isn't, it's 150uH, I should have done 11 turns… Oops…)  All the designs I've seen show a linear coil of antenna wire around a form, not a toroid. I'm wondering if the capacitive coupling of the toroid was different enough from the linear coil to affect tuning on 40m and above.  (The wrong inductance should have only negatively affected 80m, which definitely was tuned too low.) Used the feedline as a counterpoise, put a current choke 1:1 balun about 12 feet from the feedpoint: 13 turns of RG-8X around an FT240-43. You think wrapping magnet wire around toroids is a pain? CW/Digital station: Club member brought his Packtenna clipped dipole. Used it with his Flex6600 and Maestro. Worked a charm. 20m SSB was CHEEK BY JOWEL... Rod VA3ON  Teamed up with my friend (and Elmer) Peter West VE3HG to create a small scale field day for us and our two Padawans, Iuliya VE3UHA  and Dante VA3DNF. (4 total) Both teenagers licenced as Basic with Honours during the pandemic shutdown, but had yet to operate HF. Used the Oakville club call VE3HB. At the scenic “West Estate” we got a few antennas up (Dipoles, horizontal Endfed and verticals) 5 Watts on two Elecraft KX2 Stations (Commonality of rigs, preserved learning): Station A: CW  Station B: Phone and FT8 on the other New HRWB Logger appliance (with N1MM) - Avita Magus II [WT9M10C44] 10 Inches Intel Celeron 4GB RAM 64GB Storage Touch 2-in-1 Windows 10 Tablet PC Black     - rocked Conditions Phone was horrific on Saturday FT- not much better - could hear lots but nothing worked well CW great (as usual) To make CW workable we used a CW reader and keyer with preloaded exchanges and a keyboard. An approach I've not used before with rookies to shortened the learning curve. Emphasis on learning and getting the tempo. We may be seeing a lot more of these two as CW contesters - they were aggressive! Segment 3 - EmComm Software Project by Gaston KT1RUN What is the purpose? API and web app for field expedient digital communications platform that runs on RPi Offgid, mobile-first and 1-click digital operations Headless: eliminate need for VNC and/or external display/keyboard/mouse Lightweight: small footprint memory, CPU and disk => conserve power What does it do? Allows headless operation of various ham radio tools (Pat, YAAC,direwolf, etc.) on a RPi (everything runs on the Pi; the web browser is the interface) Streamlines mode switching: Winlink ARDOP, Winlink packet and APRS Streamines messaging for both Winlink and APRS through templating engine Offline callsign lookup - includes approx. distance calc based on GPS Status information: time (local/UTC, hostname, IP, CPU temp, GPS, grid square) Remote shutdown What did you use to develop it?  App and API decoupled Backend: (API) Java JDK 11 Spring Boot: DI, uber jar, systemd, oh my Lucene: IR library (search background) Custom YAAC plugin: Light-weight HTTP API (REST-like)   Frontend: (not my area) Prototype: Bootstrap and jQuery Prod: React.js: What is the project status?  Do you want people to try it out?

This week's EYE on NPI is all about discovering new things - the Digilent Digital Discovery with High-speed adapter bundle (https://www.digikey.com/en/product-highlight/d/digilent/digital-discovery-with-high-speed-adapter-bundle). The Digilent Digital Discovery™ is a combined logic analyzer and pattern generator instrument that was created to be the ultimate embedded development companion. Digital Discovery was designed to optimize channels, speed, and portability. A small form factor facilitates easy storage and provides a whole suite of advanced features to allow you to debug, visualize, and simulate digital signals for most embedded projects. Digital inputs and outputs can be connected to a circuit using simple wire probes or breadboard wires; alternatively, the Digital Discovery High Speed Adapter and impedance-matched probes can be used to connect and utilize the inputs and outputs for more advanced projects. We're big fans of the affordable and powerful Digilent Analog Discovery (https://www.adafruit.com/product/4652) so when this logic-analyzer version popped up on https://digikey.com/new we snapped it up to check out. The specifications of what you get, for the price, are pretty amazing: 32-channel digital logic analyzer (1.2…3.3V CMOS, 8 channels at 800MS/s*, 16 channels at 400MS/s*, and 32 channels at 200MS/s) Digital Bus Analyzers (SPI, I²C, UART, CAN, Parallel) 16-channel pattern generator (1.2…3.3V CMOS, 100MS/s) 16-channel virtual digital I/O including buttons, switches, and LEDs – perfect for logic training applications A programmable power supply of 1.2…3.3V/100mA. The same voltage supplies the Logic Analyzer input buffers and the Pattern Generator input/output buffers, for keeping the logic level compatibility with the circuit under test. In particular, 32 channels of 200 MS/s logic analyzer input is rare to see in a sub-$1000 logic analyzer. 8 channels of 800 MS/s is also incredible, if you need that kind of speed, it's very hard to find an affordable analyzer. The wide/fast rates means this analyzer would be great for analyzing wide 8/16/24/32 address/data busses that normally you wouldn't have enough pins for. You could also check on fast protocols that normally aren't logic-analyzer friendly like RGB matrix and parallel TFT displays. Inside is a Xilinx SPARTAN FPGA and some memory for buffering signals. Like many logic analyzers, the Digital Discovery connects over USB and uses free desktop software for communication. The software in this case is called Waveforms, and is available for Mac, Windows, and Linux including Raspberry Pi (https://store.digilentinc.com/waveforms-download-only/). The same software is used for the Analog Discovery, so if you've got one of those, it'll be familiar. The software is powerful and has a lot of options and capabilities, so we definitely recommend going through some of the tutorials available on Digilent's site, like this nice walk-through on analyzing an old-school NES controller - here's a hint, it uses a serial latch! (https://blog.digilentinc.com/nes-controller-digital-discovery-waveforms/). What I use logic analyzers for is usually decoding I2C and SPI transfers while writing drivers. So I was happy to see a range of built in analyzers such as I2C, UART, CAN, even HDMI! To test it out, I connected the analyzer up to a BNO080 sensor I'm working on. I enabled I2C datalogging on the two initial pins. You can see the data stream with decoded hex values and read/write flags on initial addresses. You can also open up the events tab to see the data as a list with timestamps. The event data (or even the raw pulses) can then be exported to a spreadsheet. There's also a powerful scripting system. You can perform analysis, read data and decode protocols. (https://blog.digilentinc.com/decoding-vga-on-the-digital-discovery/) There's also a logic waveform generator you can script as a simulator for devices. (https://reference.digilentinc.com/learn/instrumentation/tutorials/hd44780_digital_discoverystart) We're pretty confident saying that for the price, this is the fastest, most powerful, capable and customizable logic analyzer you can get. And for students, it's super affordable and easy to store. Pair this up with an Analog Discovery for a full EE lab without giving up tons of desk space. Pick up a Digital Discovery from Digi-Key today at https://www.digikey.com/short/zfhz4r . You can pick up the version with high speed probe kit, or, if you aren't planning on using over 200 MS/s, the affordable basic version is at https://www.digikey.com/short/zfh997

Test tools can be expensive; in some case, very expensive. But if your needs don’t extend to the leading edge, you may find that there are some much lower cost tools available. That’s an area that Digilent specializes in. And according to Steve Johnson, Digilent’s President and General Manager in this week’s Embedded Executives podcast, you may be surprised that most of your needs will be covered.

George, Brittany, and Jeremy just returned from Hamvention 2019 in Xenia, OH.  We had a record year this year - there was no shortage of folks who stopped by to say hello and to pick up our build projects!  In fact, we were so busy that we didn’t get our usual level of coverage this year. A big THANK YOU to everyone who stopped by to say hello and support us.  A special big thanks to the guy who bought my go box! We interview Eric from Elecraft on the new K4 Direct Sampling SDR HF Transceiver, Mike from Flex Radio on the new multiFlex feature, and Kaitlyn from Digilent on the new Analog Discovery Studio.  We also include Hans Summer’s presentation from FDIM.

Die Kurzschluss Junkies sind unterwegs und reden mit Raphael und Dominik über Ihre Erfahrungen als Berufseinsteiger, persönliche Interessen, Projekte und Weiterbildung. Dominik empfiehlt für kapazitive Touch-Anwendungen einen PSoC von Cypress. Für eine 1-Button Lösung hat er den AT42QT1012 ausgewählt. Dieser benötigt keine Software um einen Touch Button zu realisieren. Außerdem weist er darauf hin , dass eine Ground-Plane auf dem Board besser gehatched wird, also die Kupfermasse der Plane zu reduzieren. So erhält man eine gute Schirmwirkung, ohne die Signalstärke zu sehr zu bedämpfen. Raphael empfiehlt für FPGA-Entwicklung Evaluation Boards von Digilent (bei Amazon) und Terasic. Weiterhin erzählt er von den verschiedenen Toolchains und die Eigenheiten von Verilog und VHDL. Bei opencores.org gibt's viele Beispiele von denen man lernen kann. Dominik und Raphael erzählen von den Erfahrungen als Berufseinsteiger und wie sie gelernt haben nach dem Studium Elektronik zu entwickeln. Sie geben Tipps, wie man mit dem Gefühl umgeht, keine Ahnung zu haben und wann man aufstehen und sagen soll: "Keine Ahnung, kann ich nicht." Zur Weiterentwicklung nutzen wir alle das Internet, Bücher und auch Schulungen. Aber im Endeffekt ist alles Learning by Doing. Das Entwickeln von Hardware ist eine Mischung aus Wissen, Erfahrung, Interesse und Black Magic. Natürlich haben wir auch über private Projekte gesprochen. Raphael entwickelt gerade eine Löt-Station für Weller RT Lötspitzen. Der Grund dafür ist ein Elektor Artikel, der ihm negativ aufgefallen ist. Seine Station bekommt den STM32F103 als Mikrocontroller, hat mehrere Varianten für die Strommessungen, ein Display und eine Schnittstelle für Erweiterungen. Die Dokumentation wird dann HIER zu finden sein, wenn er damit mal angefangen hat. (Wenn da noch kein Link ist, hat er noch nicht angefangen) Dominik beschäftigt sich mit Word-Clocks. Er hat da schon einige gebaut, jetzt gerade baut er eine Armbanduhr-Variante mit Alu Gehäuse und super kleinen Bauteilen. Zum Schluss erzählt Raphael von seiner Zeit als Werksstudent in der ASIC-Entwicklung.

When working with circuits diagnosis and design become nearly impossible if you can’t see what’s going on.  Digilent has created a super portable and affordable instrument that when combined with its Waveform software suite, it delivers to its users a bench worth of test and measurement instruments in a USB device slightly larger than a deck of playing cards.  George has been a huge fan of this device for a while and suggests that it’s a great option for those who need a lot of capability on a budget or those who need a lot of instruments in a portable package.  Join Kaitlyn Franz, Instrumentation Product Manager for Digilent, as she introduces us to the many functions of the Digilent Analog Discovery 2.
