The Switch for the mute module is mounted on the pole next to the Kidney Sound Table, and is labeled for easy use.
Specs
A stereo relay and associated circuitry (NPN transistor and resistor) pulled from the boneyard is powered by 5v from a USB power adapter on board, and triggers when the pins are tied together. Pins are connected through a cable to the mute switch mounted on the pole. the stereo relay is connected to two female 3.5mm audio jacks, connected to the Raspberry Pi and the Amplifier.
This device is designed specifically so that it could be used to mute any project with the use of any type of switch. the item includes provisions to be modified to drive the WOPR's indicator LEDs so that they can show when the WOPR is muted.
