the rules state you cant pull any power out of the operator interface, and I think there must be some reasons behind that.

last year we used 4 superbright LEDs on a heads up display, so the operator could see status signals on certain functions on the Bot (arm all the way up, all the way down, that type of thing)

they were connected only to the LED outputs on one of the joystick ports, and we had problems with our link kicking off during the matches, and with the OI reseting itself.

We disconnected the 4 LEDs and the problems stopped.

Might have been a coincidence - we never got to the bottom of it.
Could the LEDs have been drawing too much current? The LED output pins on ports 1 and 3 of the OI are only rated to source 10mA. I just did a quick google search, and some of the superbright LEDs I saw are supposed to draw 20mA+.

Ian: If I were going to do something requiring it, I'd probably get a 9V battery enclosure, and just make sure to have a few on hand.
