Hi Brad....

I know there has been a fair bit of trouble on te PSH group getting the solar
part of the PS head circuit to work. Solution (even though my head still isn't
working properly) is to use a small NiMh battery and a solar charge pump. That
way when the head is locked on and not drawing much power it can charge the
battery. When it needs to move it can draw its power from the battery, which
it sounds like you would have no problem with, but as a bonus it can move
around for longer periods without having to stop and charge a cap.

I am using a 5V 500mA hours NiMh battery from a radio phone. Very small and
could power the head for 8 hours of continous movement if need be.
