Well I have had to do an errata on my power supply, Sorry if this has caused any problems to anyone. The final P/S has 9v for driver board,6v for brain, 3v and 6v for my 35mw green and 200mw red laser's. Also 4.5v and 5v for later add ons. The P/S has now been installed on my robotic base and connected to RSV2 and is working great with no over heating. Next I will be utilizing RSV2's foot and tilt sensors intergrating them into the bumper system on my robotic base.I am also looking at using the two spare geared foot motors in conjunction with the tilt and foot sensors. Watch this space.
