the headset has resistors in it for sense of what key is pressed. Can this be expanded on? like for-
- resistance measurement (if fully ranged I could almost turn it into a typewriter - which I wouldn't mind)
- data transmission (with audio being used for transmit - you can connect an infrared LED for an) infrared transciever, or could bit bang the I2C protocol (record or be master)
