This is why there are PCB fab services
So the kid decided to teach a soldering workshop at geek camp. Of course that means a custom PCB (and custom firmware, but that’s not my department). Which meant that I finally got to test all those tutorials about etching … Continue reading
The Pin Dance
Don’t get me wrong, I love Circuit Python. Sure, I could get stuff done in the ugly stepchild language that is Arduino, but the niggling details, the mediocre IDE, none of it was my friend. And truth to tell, it’s … Continue reading

Pedal Assist: Not What I Thought It Was
It’s been a few years since I started wanting an e-bike, but for a long time I was put off by physics. We live at the top of a steep hill, and I’m fat and out of shape. So all … Continue reading
Thank you, Electronics Goldmine
I admit it, I have an addiction to things that call themselves bargains. Down in the basement are multiple cubic feet of random electronic and mechanical components that looked like a good idea or might be useful someday or just … Continue reading

Something actually useful
Our dishwasher is getting to be a certain age. And the plastic parts are showing it. Especially after one of the youth tripped over a cat and onto the bottom rack. When the wheels fall off they have a really … Continue reading
Lasercar Lives!
I know it’s not much, but the new version is ready for coding. It knows how far it is from obstacles (in front), it steers, it goes forward and backward. And it does it all in python. Code and current … Continue reading
In praise of useless information
About a year ago, back when we were still doing laser night at Local64, C did a nice backlit laser-cut sign for me to put in the door downstairs, using a font that wasn’t properly speaking a stencil but still … Continue reading
Let There Be Light
I remixed an old openscad christmas tree design to include space for a coin cell and an LED. Coincidentally I have a bunch of green LEDs lying around — their light gets through the plastic a lot better than the … Continue reading
Maker Faire day 2
Huzzah! Today we were inside and had decent wifi. Bill started right up and connected with no problem, and we spent the day cutting and engraving for curious onlookers. The exhaust went out one of the Coach Barn’s venerable windows, … Continue reading
