here's a tough one... 6v car
Yes, a car with a 6v eletrical system (old Porsche. VWs, Studebakers, Model Ts and many others over the years were 6v also).
So... I have an old Laptop (Dell Lattitude 166mmx) and I'd like to use it as a MP3 stereo in my car. I don't need/want fantastic sound, or a massive amplifier or anything like that.
As far as power (which is why I'm posting), I have a few options. One would be to convert the car to 12v - way to expensive though. So I'm stuck with either using a 6v-12v inverter, or a second 12v battery (deep cycle I'm guessing) that either I'll have to charge every so often or rig some other charging system for it.
The inverter I'm considering is at JC Whitney: http://www.jcwhitney.com/item.jhtml?ITEMID=793&BQ=jcw2
I'm an electrical id10t, so any and all advice is appreciated.
