AR.Drone - Quadrotor helicopter with wifi and 2 cameras - AR.Drone games for iPhone and iPod touch. Remote GPS tracker + Accelerometer. This summer there are a few projects I have planned.
One of the first is a model rocket tracking / data-logging system for some launches I am planning on performing this summer. I recently came across a good supplier of F and G series rocket engines for a very reasonable price. FSR Sensor tutorial. Build your own paper rocket!
