If you want a cheap switching regulator I've used these and they work well, price is hard to beat. http://www.suntekstore.com/20-x-mp2307-3a-dc-to-dc-step__down-power-module-kis__3r33s.html They're larger than a 7805 but still pretty small and good for up to 3A. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
