Things I would like to 3D print
Last year I started collecting ideas of things I would like to 3D print one day, on Twitter. Twitter is fundamentally ephemeral, so I'll collect it here instead. I got up to 14 items on Twitter, and now I'm up to 25.

An ode to the 10,000 RPM Western Digital (Veloci)Raptor
Back in 2004, I visited a now bankrupt Dutch computer store called MyCom 1 , located at the Kinkerstraat in Amsterdam. I was there to buy a Western Digital Raptor model WD740, with 74 GB of capacity, running at 10,000 RPM.

Pentium on a 386 Motherboard
I was wondering what would be the ultimate upgrade for my 386 motherboard. It has a soldered-in 386 CPU, an unpopulated 386 PGA socket, and a socket for either a 387 FPU or a 486 PGA. It might even be compatible with a Weitek processor, though I’m not entirely certain. There’s also a possibility that it has a…

Mezzano on Librebooted ThinkPads
I decided to try running Mezzano on real hardware. I figured my Librebooted ThinkPads would be good targets, since, thanks to Coreboot and the Linux kernel, I have reference source code for all the hardware.

A partially-automated medium-throughput homemade cider press with lasers
Most people who know me well know I really like apples. I'm a big fan for a lot of reasons- taste, texture, the fact that they're a symbol of my favorite season, the sheer quantity of accessible food that can grow on a single tree, et cetera. Last year, I decided I wanted to make some homemade apple cider. I bought a…

The Insane Innovation of TI Calculator Hobbyists
In the mid-to-late 2000s, you either knew, or were, that kid in grade school. You know. The one who could put games on your graphing calculator. You may be surprised to learn that some of these people didn’t exist totally in a vaccuum. There was in fact a thriving scene of hackers who had bent these calculators to…

A USB Fan Controller that now works under Linux
Relying on the built-in motherboard headers on server grade motherboards to reliably control fans with Linux has been a crapshoot since forever. I'm pleased to report that last summer the Corsair Commander Pro received native Linux kernel driver support in the 5.9 release.

Solar Shed Summary: My Off Grid Office
A few months ago I moved to a few acres in the country, and needed somewhere to work - so I built myself a solar powered off grid office out of a Tuff-Shed Pro Studio! On one side, I’ve built a great desk corner with plenty of power and more than enough AC to keep me cool when it’s over 100F out.

Gentle introduction to GPUs inner workings
This article summarizes some lower level aspect of how GPU executes. Although GPU programming is not that complicated when compared to CPU, it also doesn’t match to what hardware is doing exactly. The reason is that we can’t just program GPU without some API, which is an abstraction over its inner workings. Since few…
