Good! I need something different, I'm tired of my m3 not starting with the car, or not putting out enough on the +12 line. I tried to run my wifi router from it, and it would trip up and reset the computer occasionally. Now I've got the router running battery V, which is fine except it can't take the dip from starting and resets, so I've got a 20 sec delay across the networked things in the car. Ideally I'd like everything running from a single power supply, including the Apple TV 2... That one has a sparkfun dc-dc converter running at 3.4 volts right now, draws less than .25 amps from a 12v supply at full power. I wonder if it would run right off the 3.3 rail.
