An electronic strategy board game about mining an asteroid and barter. It is also fully compatible with Settlers of Catan. All design files and firmware is available -- you can manufacture a copy yourself!

uBiblio is a small and fast web application for managing your personal library (and share it with friends, or a book club). It provides a unified interface for physical books and ebooks. It is free, open-source, designed for self-hosting, and will never contain ads or spy on you.

An electronic and mechanical music box I built as a gift. It plays traditional Vietnamese music. It took way longer than expected to complete!

This is a small robot I made as a kit for schools to teach autonomous navigation. It is cheap, easy to manufacture, and flexible.

Tiny magnetic indicator lights, for elderly people who need help finding their way at night. Lasts for years off a single CR2032 cell.

These are a short series of minor projects, all of them fun... but not really complex enough to write a lot about.

A particle detector for muons, alpha particles & freinds. Which I needed for... reasons. And also science (but mostly reasons).

This is a spicy little quantum true random number generator I designed for fun. How can something like that be spicy? Well, brace yourself for some strange design decisions.

A small, fully self-contained server monitor. Apply power via USB, and it monitors the status of up to 8 servers, displaying the results on RGB LEDs

It's been a busy month, so this is just a simple duty-cycle controller for a dimmable lamp. It uses an attiny10 to handle high-frequency, flicker-free, and relatively efficient operation.

Most of my colleagues just take photos of business cards now instead of exchanging them. So why not do something more fun than a plain piece of paper?

My first attempt at making electronic business cards was fun, but not as fun as a game of Pong would be! Plus, I've always wanted to write a game for the attiny10.
