This is why there are PCB fab services

Posted on July 24, 2022 by paulwallich

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 →

Let There Be Light

Posted on December 4, 2019 by paulwallich

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 →

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 →

CircuitPython for early hardware exploration

Posted on April 3, 2019 by paulwallich

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 →

How small can a makerspace be and still be useful? That’s what we’re going to find out. My friend Lars has decided to devote the spare office at Local64, the downtown co-working space, to making. First in, my Glowforge, on … Continue reading →

Vindicated

Posted on June 12, 2018 by paulwallich

About two years ago, for no really good reason, I designed a 3D-printable setup for coupling those standard gearmotors to Lego bricks and axles, and posted it at Youmagine. Hardly anyone liked it or downloaded it. Then, last week, Adafruit, … Continue reading →

Burning down the house by remote control

Posted on March 9, 2018 by paulwallich

A few weeks ago I blew up my Octoprint installation by adding and deleting too many extensions at the same time. Before reinstalling, I thought it might be a good time to upgrade a bit.  So now there’s a cute … Continue reading →

The finicky details are the easy part

Posted on August 7, 2017 by paulwallich

Glowforge!

Posted on July 12, 2017 by paulwallich

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 →
