Thursday, October 30, 2008 PC Power Supply

The great companion to the wiper motor - an old PC power supply. This one provides three output voltages rated at 10 amp each - 12v (yellow wires), 5v (red wires), and 3.3v (orange wires). The great thing is that the three output voltages and the wiper motor 's dual windings in combination produce quite a range of RPMs. For instance, the 5 volt output connected to the low RPM motor wire produced the perfect speed for the Flying Crank Ghost.

I mounted a nylon terminal strip to the case of the power supply and terminated the output wires there to make it easier to use in a variety of props.
