Hi,
I wanna share my project with you;
it took some time to get my BrickPI repaired, make the video and documentation … really, this took more time than to “make” the project 
My Project:
Lego 9398 4x4 Offroader with original PF L-Motor,
PF Servo Motor, RaspberryPI, BrickPI, Wifi AP, RPI Cam, Ultrasonic Sensors for collision detection.
Controlled by Smartphone’s motion (accerlerometer sensor) and video stream with about 0.5 sec delay.

(short) documentation here:
