[Jeff] and his team completed this iPhone controlled rocket launcher as part of their final project at Georgia Tech. Two servos provide the rotation referenced by an onboard electronic compass, and elevation control for launch. These are interfaced with an eBox 2300 using a few Phidgets boards.
Check out the launch video below. It’s too bad that they went with a commercial solution for servo control rather than building it themselves (especially considering it is an embedded systems class). But it is a nice build none the less. Now they need to add some imaging equipment to the rockets and they’ll be in business.

[Josef Jahn] has posted a detailed guide on building a microcontroller-based launch box. Constructed from an Atmel ATMega168 and powered by a 12V rechargable lead gel battery, the launch box is fully portable and includes a number of safety features. Going the extra mile on what could essentially be a simple push button launcher, he added three safety switches, a sixty second after-launch timer and a beautiful (not to mention rare) PLED display complete with dramatic status messages. Check out a video of the launcher in action after the break.
