Talking Re: Camera freezes

I have read a number of messages on Chief Delphi
and have concluded the following about the camera
system. - power supply issues need resolution.

1) Add charger to 12V battery powering green
lights to ensure that the battery is fully charged
and enough power available to light green lights strongly
(not mentioned but I think a good idea).

2) Intermittment connections between moving pwm
cables and robot controller can cause camera resets.
Recommend solution 1) solder pwm cables to
camera board possible solution (legal?)
2) superglue pwm cable connectors
and add mechanical support (black electrical tape?)

3) 7.2 volt Ni-Cad battery cannot discharge below
7.0 volts without camera operation becoming flaky.
Solutions 1) Purchase extra 7.2 volt Ni-Cad for
competitions to insure fully charged battery available
More difficult 2) Build FIRST IFI charging circuit to charge
7.2 volt Ni-Cad circuit pack during competitions
Debug solution 3) Use regulated 8.0 volt power supply to camera during camera debugging to elimate this potential
issue.
