A story about a raspberry pi laptop Once upon a time I was excited about typewriters. Wait a minute, I am still excited about typewriters. Once I was excited about typewriters, but also computers. I knew I liked the immediate typing experience and the “nothing can interrupt me now” flow of having one and only… Read More


I previously built a Roubo phone stand that gets used all the time. But phonestands are so useful that I have more. A lot more. I designed this one in OpenSCAD, a free text-based CAD program, and it is fully parametric. You can adjust the size and the angles to ridiculous degrees. But this is… Read More


We’ve all seen (and heard) the battery bluetooth speakers. I wanted to make one that was still portable, but a bit more serious. Here’s my drill-battery powered speaker. It all started with the drill battery. It’s just sitting there, high-powered and easy to recharge. I found a thingiverse file that fit my ryobi battery. I… Read More


I built a one handed keyboard last year and it got me hooked. This week I finished my third keyboard build: I’ve been using may handmade split planck for a while now, and I love it. It is fast and efficient and a joy to use. However, it is not awesome for games. The lack… Read More


In my last post I talked about upgrading my 3d printer to use a better hotend with interchangeable nozzles. Since then I have broken and fixed my printer again. First the break. The new hotend has one of those pipe fitting clamp things that grabs on to the bowden tube (the tube the filament runs… Read More


Let’s get this out of the way: 3D printers are awesome. I have had mine for about a year and a half and it has let me build fun and crazy things like my homemade keyboard. But 3d printers are obnoxiously slow. It makes sense; it’s the world’s tiniest glue gun putting down layer after… Read More


I like the potential of electrical conduit for construction. I’ve seen people sell expensive connectors that turn these into a construction set, but why do that when I have a 3d printer? I modeled some tabletop connectors in OpenSCAD and then some tenons that go in the end of a piece of conduit and then… Read More
