I’ve been doing some work for the Perth Linux user group – PLUG for their AV project. I’ve added a Tally Light page to document the process of how I designed them – please take a look and let me know what you think. The article is here: Tally Light.

The whole project is going to be run as an open source effort, so I’ll be publishing the circuit design, all the AVR source code, and any supporting scripts we need.
