Start searching electronic surplus. Typically 24VDC to 5VDC converters come up for quite reasonable prices. I have bought a few over time. Never paid more than $20 for one. Note you may need to add a heat sink to one for it to handle it's full load. On your battery choice. I sugest looking at large capacity NiCD batteries. 10-20AH NiCD batteries are available. They generally are E or Extended E sized. Note each one will set up back $20-30, and you will need atleast 5 as they are 1.2V nominal. 10 equils 12V, 20 = 24V. The advantage is they have a much higher energy density than lead acid. Another option is to look at the battery packs for video cameras and lights. http://www.bhphoto.com/ sels them as well as many other places. This gives you a standard battery pack that you can replace in a pinch buy just buying one off the shelf. Typically video cameras work off of 12VDC or 14.4VDC. You can always run them in series. -- | Bryan Andersen || http://www.nerdvest.com | | Buzzwords are like annoying little flies that deserve to be swatted. | | -Bryan Andersen | -- Subscription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" to
