Hey, is it possible to hook up cold cathodes with out plugging them into a computer power supply? The power supply give 12Volts DC. Can't i just use a DC plug that converts 120 V AC to 12V DC from a wall socket, splice the wires and hook them up to the cold cathode inverter? I want to get two 12" blue cathodes and put them behing my desk so they illuminate the wall. Whats the best way to do this without a computer power supply.
