Most of silver looking brackets are from Tetrix which the holes are bigger than parts from Lynxmotion.

Put a Arduino and there’s still planty of room for battery and other sensors.

However, I guess this servo shield doesn’t like MEGA,1~9 pin doesn’t react at all. so the arduino duemilanove is used instead and It seems working. All 16 pins shows the correct pulse from oscilloscope.

There was a little incidence with the servos, he connected the power and ground in the wrong order! And they were smoking! Looks like it killed the servos :-(
