As stated above you can infact run your OI off of batteries, its quiet simple, you dont have to butcher a power supply if you dont want, you should be able to buy the connector as its a standard size, although that size espaces me right now, and just connect a batter to it.

As stated that is only half your battle as FIRST forbids the use of radio communication during competition. If your talking about just doing this for a demonstration or a parade, then your fine, but this wouldn't be possible at competition due to the radio restrictions.

Hope this helps.
