Switcher and mute button between headset and 2 computers.

Version 2 changes: Switched to using Analog Devices audio switch https://www.analog.com/media/en/technical-documentation/data-sheets/ADG733_734.pdf halved the board size de-popping the mic when mute is activated added reverse-current protection diode

BOM: https://www.digikey.com/BOM/Create/CreateSharedBom?bomId=8390108 +100k resistors +controller button/switch (just put 5v to U to mute, 5v to 2 to switch to the second audio source)

Notes: PWR USB can be connected to a computer safely to provide 5v power to the board. CTRL USB should NOT be connected to a computer, but rather to a custom button/switch. I use a USB port because it’s cheap, 4-wire, and easily available. If the 5v logic lines from the custom button/switch are applied to a computer’s USB port, it could fry the port.

16 pin DIP adapter to FuzzButton motherboard for legacy sample holders. Includes bottom Finish.

Meant to act as the male side with pogo pins to transfer connections for 2 buttons, as well as the positive, ground and data line for a neopixel LED strip in a lightsaber. These are great for making removable chassis.

Can download PCB cover here. Cover uses these pins (TCSS).

PCB for the PadSwitcher64 interface.

This interface allows the use of Super Nintendo compatible control pads with the Commodore 64 and 128.

DMX Demonstrator Control-Pro Faceplate (DMX-CPF 1.1)

The control-pro is built to work with either transmitter or transmitter-pro. When used with an Arduino, an additional board, the DMX-TX2, is required to connect the control-pro to the Arduino. The transmitter software detects whether DMX-TX1, the standard transmitter, or DMX-=TX2, the control-pro adapter, is connected.

DMX Demonstrator Receiver (DMX-RX1 1.0)

The receiver is an Arduino Shield board designed to accept the 3-wire data/clock signal from the transmitter and decode the data stream to control the brightness of 4 LEDs. It also has additional output for use with external LED drivers.
