Tongue-controlled Game-Boy

The Tongue-Boy SP is a tongue-based controller for use with the GameBoy targetted at people with quadroplegia.

The NewAbilities Systems TTK or Tongue Touch Wireless Keyboard Transmitter looks like an orthodontic retainer with nine membrane buttons

We add a new jack for the Tongue Boy SP TTK receiver input. We also add a second micro-controller computer chip inside the case to decode the TTK signals from the receiver and activate the Game Boy SP buttons.
