Re: LED Lights for the Robot (what do you use??!?!)
We've been custom-making our ring lights for the past several years. In 2011, it seemed as if we were one of the only teams, and then in 2012 everyone had them. We just wire up 12 LED's on a circular cutout of perfboard. There are 3 series sets of 4 parallel ~3.5V LED's with appropriate resistors. We use white LED's, but you can use any color. The only restrictions are that it doesn't interfere with communications, other robots' vision, and other commonsense bad things.
