Technological Crafting:

I intentionally refer to this as "Technological crafting" not being a "Maker" because all which I am doing descends from the emotional state of crafting.

Soldering your own recreational electronics has more in common with sewing your own clothes or other such crafts than it does being a professional electronics engineer.

Thus, this is my rambly set of screwing around, because I like woodworking and plastic fabrication and welding and electronics and sculpture. And the times I've sewn things, it's been pretty damn fun. So I guess technological crafting is all about that eccentric mis-mash of bizarre interests.

I'm doing AdaFruit's light painting tutorial... but I haven't a CLUE.
AdaFruit has done a series of light painting tutorials. First, they did a tutorial with the NeoPixel strips and an Arduino . Then they upgraded it to the DotStar LEDs and used a Raspberry Pi . Then they downgraded the LEDs to the NeoPixels and switched to CircuitPython . And most recently…

6502 Hack Day Build
I always wanted to build a 6502 based computer. The 6502 is the chip used in all sorts of computers throughout history, ranging from the Apple II, the NES, and the Commodore 64... all of the way through to the Terminator and Bender. I've drawn a bunch of attempted schematics, never really bothered…

6502 Stuff
The famous CPU series for the Apple II series, the Commodore 64, Atari 8-bit series, NES, Bender, and the Terminator My project stuff The 6502 Hack Day build A 6502 SBC built in a day-ish. Other eccentric and interesting stuff Dirk Grappendorf's really quite nice 6502 build Daryl's SBC2 - A fairly…

TLC5940, TLC59116, and IS31FL3218 LED drivers
tl;dr: The TLC59116 is a pretty neat part Following up to the previous entry on the CAT4019/CAV4019 LED driver , I got three more intelligent controllers to play with. All three of these are external intelligent LED drivers, two from TI, one from Lumissil. I soldered the three of them to surface…

Three and a half new ways to deep sleep in ESPHome
I've been wanting to do some stuff with solar power and low energy and ESPHome. Thing is, either of those devices eats up quite a bit of current. Less than a Pi, but still enough power to matter if you are using solar power. Furthermore, I think that ESPHome's over-the-air software update system…

Wiring up Wilf Rigter's SIMD1 V3
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…

ESPHome is pretty neat
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…

CAT4019/CAV4109 LED drivers
tl;dr: This is a constant-current driver for 3 strands of LEDS, up to 175 mA per LED, 200 mA total, with the LEDs powered by up to 25 V, with each strand having individual control lines. Available in a SOIC-16 package. I'm always looking for LED drivers and other such circuitry. This part (one is…
