There could be quite the market if someone were to sell those...
I know I'd buy one.

Re: pic: Vex power from FRC battery
LM7808 is a very old part design, it's just a higher voltage version of the extremely common LM7805 voltage regulator that is used in half of all electronic devices ever made! I got a pair on ebay for a couple bucks (including shipping), you should be able to get one from any electronics parts distributor such as digi-key.
The heat sink doesn't need to be anything more than a piece of flat aluminum about an inch square...if that.... (edit: digikey has a couple thousand of the LM7808 devices in stock) Last edited by MrForbes : 20-09-2007 at 01:10.

Re: pic: Vex power from FRC battery
Haven't noticed any, but it might be a good idea to add a big capacitor after the voltage regulator, eh?

Re: pic: Vex power from FRC battery
If i were you i would keep it on the DL and get a patent before you all of a sudden start seeing them with a Radio Shack logo on them.
