minimu9-ahrs. Program for reading data from the Pololu MinIMU-9 over I²C. Works on the Raspberry Pi and other embedded ARM Linux boards.

nixcrpkgs. Nice nix expressions for cross-compiling.

ruby_ecdsa. This gem implements the Elliptic Curve Digital Signature Algorithm (ECDSA) almost entirely in pure Ruby.

ahrs-visualizer. Draws a 3D representation of an IMU's orientation. Developed for Raspberry Pi and OpenGL ES. Works with minimu9-ahrs.

docker-monit. Daemon that helps you monitor docker containers with tools like monit by maintaining PID files for the containers. I use this for replylater.com and it's not very polished yet but maybe some people will find it useful.

wix-example-harvest-directory. Shell

zumo-red. Code I used for the 2015 LVBots sumo contest. Runs on the Zumo 32U4 robot from Pololu.

secp256k1-rb. A Ruby gem wrapper for libsecp256k1. NOTE: I have not released this as a gem yet; the secp256k1 gem from RubyGems.org is created by http://github.com/GemHQ/secp256k1-rb and it does not support the latest version of libsecp256k1.

websocket-chat. A minimal online chatroom implemented using HTML5's Websockets with a Ruby back end. It's pretty basic right now, and probably won't be useful to many people.
