The Chaos Communication Congress recently highlighted some of the projects you can build at their upcoming (12/27 – 12/30) event:

Even if you’ve never touched a soldering iron, you can drop by the Hardware Hacking Area and get into doing cool things with microcontrollers! Build something that relaxes your brain, turns off annoying tvs with the click of a button, or just have fun making cool blinky leds!

If you’re a coder who wants to get into microcontroller hardware, check out the Game Kit Workshop and build your own MIGNON. This open source device is perfect for beginning hardware hackers and is a great platform to write cool games for!

For those of you who have a few speed soldering championships under your belt, why not go for something really big? You’ll not only get to see the quadrocopter in action at the 25C3, you’ll have a chance to build your own at the Build a Quadrocopter Workshop. A real UAV you can fly outside the bcc only takes five hours to build! Complete kits for for the Microkopters will be available at the workshop.

Here’s the list of speakers, and here’s video of the Formica swarm robots that’ll be in attendance engaged in some type of robot war:
