The 25C3 team has a post highlighting some of the hardware workshops that will be happening at Chaos Communication Congress this year. Our own [Jimmie Rodgers] will be in the microcontroller workshop area building kits with many others. The folks from mignon will be bringing several of their game kits for another workshop. We saw quite a few quadcopters at CCCamp and the team from Mikrokopter will be back to help you construct your own drone. They say it only takes five hours for the full build, but space is limited.

You’ve probably seen musical Tesla coils already. People have wired them up to computers and keyboards to make them serve as dangerous and awesome speakers. This video popped up of someone playing his guitar through one. It is rough, and not very good at polyphony, but still cool. We would like to see several coils, split by different filters to be able to hear more of the guitar chords. If only someone had rigged these up for Queen when Flash Gordan was made.

PS2 Controller Thermometer

Finding themselves in need of a thermometer that could communicate with the computer, The Cheap Vegetable Gardener resorted to a bit of hacking. They created this PS2 controller thermometer by attaching some thermistors to the analog stick inputs. Each PS2 controller could collect data from up to four thermistors. There is an auto shutoff feature built into the controller that shuts off the analog signal after a period of non use. To overcome this, they simply taped the L2 button down.
