i need to get my carputer set up, but dont want to keep running in and out of the house to my car to do it. my system is using the opus 90w board with the 12v hot, ground, and acc connections, but i want to work on it in my house. can i buy a standard 120v AC converter to 12v and splice the wires to the opus pcb wires? do i need to worry about mA ratings?
No announcement yet.
dumb-*** question-120v to 12v..????
