I'm almost positive there was a spike in current caused by our motors when the robot turned (we really need a better drive train and the motors literally fight each other). My only worry is how to protect the camera. I'm thinking a resistor or a DC regulator. Also I'm considering using a capacitor to provide power to the camera when the motors cause a power dip, and I'm wondering if this fits under the "no other power source rule". Any help or advice would be great meanwhile ill shop for another camera.  |
Well, if you really had your camera connected to a Spike, then that's your problem. Spikes will output the battery voltage, which should be around 12 V, and the camera was supposed to be connected to a PWM header, which should output about 7 V. It's actually quite impressive that a sensitive device like the camera lasted such a long time running at a voltage
70% bigger than its rated voltage.
