Note: apparently lucky with the parallel 7805's. It seems but for the little bit of resistance in the solderless breadboard this probably wouldn't have worked.
It's on to the next step... what is the next step?
Oh yes, the upper gripper servo is kaput and I don't have another of the same size... will use smaller size replacement. <optimism> Maybe it'll work better </optimism>.
On second thought I'll use the standard servo... Futaba 3003.
