Not entirely true; the gyros were powered off the 5v out, and so was our camera.

<R57> The use of additional electronics is intended to allow teams to construct custom circuits for their robots.
The custom circuits may be used to indirectly affect the robot outputs by providing enhanced sensor feedback
to the Robot Controller to allow it to more effectively decide how to control the robot. In addition to the
required branch power circuit breaker, smaller value fuses may be incorporated in the custom circuits for
additional protection. All outputs from the custom circuits must be connected to the analog inputs, digital
I/O, TTL Serial Port, or Program Port on the Robot Controller.
It only says that a custom circuit must be connected to analog inputs, digital i/o, or serial ports. It doesn't say that you must draw the power from the circuit breaker. Of course, if you do need 12v, then yes, you do need to go through a circuit breaker/fuse according to other rules, but if the 5v is enough, then go for it.

And I've had a change of heart and might buy a Chicken-AID when they come out. Making my own would require a ridiculous amount of work that I really don't feel like doing...
