Social bookmarking integration is all-the-web2.0-rage. But looking at the costs, can you really afford to run your own? Server upgrades, bandwidth allocation, spam management…What a headache! Here’s a simple way for you to add a social-networking system to anything you own, for a minimal investment: The Digg Button Kit!

The Digg button is a very simple beginner electronics that teaches how to solder and program microcontrollers. 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, 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.

We already have a couple simple projects to get people started: how to power it from USB or batteries, how to make it scroll a simple message, etc. We’ll be updating the mods as more people get their hands on the kits.

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…)
