The scorpion bug was operated from the car battery, but it is double-heatsinked. I did, however, manage to burn it out, but that was because I was running hot with a flat 3300mAH battery. Torture test, and it didn't make it. I think I'll double the 7805's for a 12V analog reg next time. Hey, my heatsink has two screw-holes, they can share it, and that will place them both at about the same temperature, reducing the chance of thermal runaway.
