The Digg button is a very simple beginner electronics that teaches how to solder and program microcontroller. Once made, this basic electronic project mimics the popular Digg.com website: each time you push the button, the button flashes "Dug" and increments the counter up to 999 "diggs". The project is completely open source, and documented here including parts list, schematics and code. For those who don't want to try to chase down the electronic components, we have a full kit ready to go in the Adafruit webshop.
For every sale of the Digg button kit we're giving $1 to the EFF (Electronic Frontier Foundation). The kit is currently in its first release; new colors and other projects will be available. We even have a plan for making it interface directly to digg.com! (Stay tuned...)
Coolness. You get a digg button, some innovative people get rich, and the EFF gets paid. That's right, everyone wins.
