CircuitPython for early hardware exploration
I’d expected the software side of using CircuitPython chips to go more easily than coding in Arduino, but what I hadn’t really expected was for the hardware side to go more smoothly as well. It’s early yet, and most of … Continue reading
Cooperative Editing whether you want it or not
The last time I tried teaching some kids how to program arduinos, the room we were in had no wifi to speak of. Getting working copies of the desktop IDE onto half a dozen ancient underpowered windows laptops was a … Continue reading
Glowforge!
My laser cutter arrived a few weeks ago. It’s pretty cool. Partly because I’ve been anticipating it for the better (worse?) part of two years, but mostly because it’s just there. I’ve used a laser cutter before, and this was … Continue reading
Buy extension cords, not wire
When you’re in the sticks, your supply options are limited. That’s why the other day I bought a couple of extension cords instead of the bulk wire that was right on the other side of the aisle at the hardware … Continue reading
Solder first, Trim Headers Later
I had a bunch of Adafruit Metro Minis to solder up for a workshop I’m teaching, and –as usual — almost all the header strips were longer than they needed to be. I guess it’s much quicker to pack a … Continue reading
Lubricate your fans
(tl;dr: if you have a fan that cools your hot end or heat break, lubricate it. It may solve some problems.) It’s a good thing I splurged on the dual extruder for my printrbot way back when. Not that I … Continue reading
Everything is parallel
Or at least multithreaded. I was prototyping some vaguely image-related ideas in Processing, and decided that I wanted to pick which image file I was going to mess with on the fly rather than hard-coding the filename and path into … Continue reading
