Hey, guys!
I'm off on another project (again). I'm going on a vacation this week, and I was hoping someone could help me find a homemade (if possible) circuit for a 12vdc to 120vac converter, so that I can use my laptop on the road (the battery is dead and I need to plug it in). I'm not sure of the wattage that I would need (for 120v, 1.5A, would you just use ohm's law and multiply them together?), so I'm a little stuck. I can't really afford an actual inverter at this point, so I was hoping I could make one of my own. Does anybody have a circuit that can provide 120vac, 1.5 amps from 12 volts dc from a car cigarette lighter?
Thanks for the help!
