[Перевод] Hardware is hard: разработка визитки с микроконтроллером, светодиодами и питанием по NFC

У моей визитки, как и у большинства, собственной батареи нет. Но достаточно поднести её к телефону, как микроконтроллер запускает анимацию по 21 светодиоду, получая питание исключительно через NFC. Этот проект я начал около трёх месяцев назад, чтобы без лишних усложнений набраться опыта в проектировании печатных плат. Вот только «без лишних усложнений» продолжалось недолго. В процессе разработки этой визитки я получил гораздо больше опыта, чем планировал, да и сам конечный результат мои ожидания тоже превзошёл. Все детали проекта можно найти в репозитории .

Been trying to get the Tri-color ePaper display to work with this "bonnet" on my #RaspberryPi 4 for the past hour but nothing is showing up despite there being no errors on the software side. Even the demo program doesn't cause anything to be displayed. Not sure what to do other than bit-bang the SPI interface, and I don't want to resort to that if I don't have to. :/

My latest blog post: Extending CircuitPython with Native Modules - Part 2

https://mikecoats.com/extending-circuitpython-native-module-2/

For CircuitPython Day 2026, I wanted to get close to the metal and write a module in C that I could call from CircuitPython. This time, we're looking at adding a module-level method.

Today is a good day! Building my very own controller setup with 16 #arduino encoders from #adafruit, tightly coupled with #emacs, #supercollider, #openframeworks and #commonlisp

Quick Post #8: Update to Multi-Function Display Using PyPortal
About 7 years ago, I got a PyPortal and used it to cycle through and display 3-5 types of information. Over time, I sometimes varied the information (it had a COVID display during the worst of COVID, now replaced with pollen counts). And as API's for the information came and went, I made other changes. But it still used the original, now a

Ordered myself a bunch of #adafruit quad encoders... About time to start building myself an improvisation instrument for #commonlisp and #supercollider, centered around #emacs. This should be fun :-D

Damn. The shipping for the #pimoroni Badgeware Tufty from #adafruit is between a third and just over half of the price of the Tufty itself as UPS is the only shipping option (afaics). Probably because of the battery. Pity they don't have a pickup window as their factory is less than a mile and a half from me

Behold the $350 Raspberry Pi 5 with 16GB RAM, because apparently, the world needed a DIY computer that costs as much as a discount laptop 💸🤦‍♂️. #Adafruit wants you to believe it’s "unique" and "fun," but we all know it's just a glorified excuse to hoard more useless cables and kits that you'll never use 🔌📦.

I just received, assembled, and configured the Anavi 12-key Macro Keyboard. There is a python file that shows up on a USB filesystem that appears when the keyboard is plugged in, which is easy to configure to produce any macro keys. I'm using it to control OBS hotkey scripts for live streaming. I highly recommend this keyboard.

Some company cease-and-desisting Adafruit over review of "AI tools" (I suspect negative reviews).

I'd say no to downloading ANY app that does this, but I think this is just one of many reasons to NOT download the new White House App.

#Adafruit did everyone a great service with this research:
The official White House Android app has a cookie/paywall bypass injector, tracks your GPS every 4.5 minutes, and loads JavaScript from some guy's GitHub Pages.

I wrote up a bit about the two (!) alt controllers I made for this game jam: one looks like a keyboard but is actually a tilt controlled WASD pad; the other one looks like 5 toggle switches but actually is a keyboard. Sort of.

I'm sorry, but I can't believe for a single second that either Phillip or Limor are so batshit bonkers that they seriously think the pushback to #Adafruit embracing #AI is down to sexism.

They know fully that the opposition is widespread, founded on broad ethical and technical objections, and they are falsly, shamefully, and cynically invoking misogyny as the cause.

Even a cursory glance at the replies to their recent posts reveals an incredibly diverse crowd expressing their disappointment.

My current setup for digital community archiving projects:

open hardware (#raspberrypi) as interfaces. small screens to avoid sitting *behind* laptop screens (pi 400, #adafruit cyberdeck hat, #clockworkpi #devterm).

portable #scanography for creative tracing and mapping.

graph writing in #obsidian, with self-hosted livesync and other plugins (dataview, graph link types, juggl). can be combined with social media webarchiving.

this all is building on prototyping and experimentation in the cooarchi.net art-doc-archive.net #urbandermatology and #opferschicht projects, and recently in the @MuseumfZK

Uh-oh. The Adafruit fairy paid me a visit. I'm now in the "two free dev boards and a coaster" customer tier.

Almost done with assembly of the #PiDP-11 (PDP-11/70 replica) kit. Still waiting for some connectors to arrive from #Adafruit for the back panel that bridge to those on the Pi inside.

Booted up into RSX-11M-PLUS, an OS I haven't touched since high school. As the Pi on the inside is connected to my wifi, I'm able to SSH into the console and login as SYSTEM (lol).

"Last interactive login on Tuesday, March 30, 1982" -- pretty close!
