Use two CR123A batteries. They are made for cameras, but have 1.4 amp-hours at 3.0V which is quite flat up to 1/2 amp load. Digikey sells them cheaper than retail: P151-ND for $4 each and they sell holders with quick-disconnect terminals: BH2/3A-T-ND. >Thanks for the info! > >PS: Do you know your sked yet? We will head up from Orange County on Monday morning to the museums in Exposition Park, then swing on by your place in the afternoon. I don't know just when, but figure sometime around 5. I'll call when we get there. --David Forbes, Tucson, AZ http://www.cathodecorner.com/
