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…

Trying out Ponoko and the FreeCAD Laser Cut Interlocking workbench
tl;dr: The Laser Cut Interlocking workbench is the first tool I've found that feels like it might make the process of designing three dimensional structures to be laser cut easier. And Ponoko is kinda neat once you get past the $14 per-order charge Why is laser cutting cool? I should probably…

Gate driver test: PWM switching a half-amp at 80 kHz PWM with a MOSFET
tl;dr: At 80 kHz where the MOSFET switches 0.5A at 5V, a gate driver makes a small but measurable difference in switching speed. It makes a clear difference in heat generated as you switch increasing amounts of power. It's better to do PWM at a high frequency. Ideally, you want the frequency to be…

A vaguely finished ESPHome node for my geekroom
Some five months ago , I wrote about how I got started with ESPHome with an ESP8266 and a temperature/humidity sensor on a breadboard. I figured that I'd build it over time. I'd realize that there would be something that would be really nice to add, and so I'd find some parts to do it, or try out…

Making an ATMega32U4 Arduino clone board from scratch
So far, the Ardunio environment seems to be the easiest way for me to get real and practical things done with hardware, most of which has to do with there being a decent open-source library for most of the things that I could write but don't want to. I've never actually purchased a real Arduino…
