This site is mostly a collection of projects I’ve worked on in my spare time over the years. Some of my recent and active projects include:
A window manager for X11 written in C. This is perhaps the oldest project I still maintain (started in 2003).
Constructive solid geometry in Scala for creating 3D models to be printed.
Maze generator implementations in lots of programming languages.
Some other things I’ve worked on in the past that may be of interest:
The Q1 Computer
A computer built almost entirely out of about 3000 discrete bipolar transistors.
Altair 680 on an FPGA
A complete implementation of the Altair 680 computer system in Verilog capable of running a version of BASIC from 1978.
My GitHub has some more projects.
