Ok I've come up with a new hairbrained project- I want to put a Wireless AP in my car attached to the Empeg. The Empeg will be running GPSD which will allow my Pocket PC to connect wirelessly to the Empeg and use the GPSD daemon which in turn allows me to use the new Pocket PC version of Roadmap in the car with no GPS cables. My big stumbling block right now is where am I going to get the 5VDC @ 2.5 Amps that my Wireless AP needs?
A 7805 regulator would seem a little too out-of-spec for this application, any other cheap ideas for this project?
