DTH : I havn't priced out the parts yet cause I didn't want to waste my time if no one was interested. I'd ship to anyone that wanted one, provided the customer pays the handling.
subcon959 : from what I've heard, people are buying adapters from radioshack casue they cant find the offical ones. And the ones you get there are cheap POS units. Where is this source for the offical adapters at that you know of?
Brad : I know that some of the adapters are crap and I want to imporve on this. That is why i wanted to know if there was interest. I plan on using some linear 3.3 volt 1.5 amp voltage regulators i have and testing that. It would be nice if you could power it from a 12 volt source like a car moron lighter, or, as you said, a seperate lead acid battery.
Maybe two different input plugs, one to plug into the wall, and another to plug into a 12 volt source. They would go to differnt parts of the circut of course. The 12 volt line to the regulator, and the 120 line to a transformer, then a rectifier, and some filtering. It would be a stable, reliable unit that looked not much different than a laptop power supply.
