Steve, if the heat is a problem on your setup, there are drop-in replacement switching mode regulators for the 7805 that can significantly reduce the oamount of heat dissipation. I used to have a super-Q-board that became so hot I ran into problems in summer - dropped in such a regulator and

There is that. Our future designs will either use a high efficiency, low heat device or they will have an ultra-high-efficiency buck regulator on them (96% efficient) in cases where the device is more complex and justifies the small extra cost. We're learned a lot, and there's much better voltage
