Re: Strange Camera Problems

Here's the one thing I can think of:

When you turn on the Fisher Prices, unless you use some ramp code, the motor brushes arc. Now, somewhere, I heard some tech nonsense about collapsing magnetic fields when arcing occurs(or rather, the arcing is caused by the collapse of the field), and back EMF, and lots of junk like that. Perhaps this could be causing it. I'm sure someone brighter than I can elaborate.

Because it only occurs when you run the collection mechanism, which only contains FP's, I wouldn't think it's a current drop issue, though that is possible. The only thing I don't get is why it occurs only when *both* motors are run. Maybe you've got your FP power lines near your camera wires, and are inducting a power or signal current. Interesting...
