I enjoy tackling interesting projects and here are a few that I've made some limited attempt to document. As many of these were carried out purely for fun, code quality and documentation may vary enormously. You have been warned.

N3: No-Nonsense Navigation Hand-Held GPS Receiver

N3 (No-Nonsense Navigation) is a handheld GPS receiver, but without all the nonsense. A toggle switch turns the device on (and off) and as soon as it has a fix, the current position is displayed on the screen. While switched on, N3 also automatically logs your journey to an SD card so you can look at it later. It can run for about 10-12 hours on a pair of AA batteries which can be changed in the middle of nowhere if neccessary.
