Step 3: In which I actually look through the example source bundle and refactor 29 minutes ago
Goal : Get more code working. I've been working on two different approaches to this problem, in parallel. On one side, there's the Feather M4 running CircuitPython. On the other, there's a ATmega328 running Arduino C++. In both cases, I've got buttons and the driver for an APA102 "DotStar" strand…

Wiring up Wilf Rigter's SIMD1 V3 7 hours ago
tl;dr: A FQP30N06L will work as the MOSFET in a SIMD1 V3 circuit, although it's not a very bright solar engine with the parts I've used. In the 1990's, Mark Tilden cooked up the idea of BEAM robotics. Instead of using complicated digital electronics, he'd wire up simple biologically-inspired analog…

Step 6: Where I reach the limits of the breadboard 1 day ago
Goal : Make sure the board won't asplode when I plug it in. I managed to not break the board after not working with it since last August. I did a careful check, made sure the wires weren't plugged wrong, etc. After doing a bunch of checks, I plug it in, connect to the serial port, and it says…

The first eight weeks of shelter-in-place stress baking with Jill 1 week ago
I'm already the sort of person who cooks and bakes and I figured that it's a lot easier for me to have the makings for foodstuffs than it is to have bread going bad in a shelter-in-place situation. But apparently everybody decided that they were going to stress-bake through the crisis. Joepastry…

ESPHome is pretty neat 1 week ago
ESP8266 and ESP32 modules are pretty neat. They are a nice combination of cheap, featurefull, and usable and, ever since a Hackaday post in 2014 , somehow gained a hacker community that enables a lot of really fun things. Also, apparently if you peel apart your WiFi-enabled IoT devices, you…
