JMN-EFP-786 James Newton Says
The head mouse: From the back of the eyeglasses, a line runs between the two ends of the frame (just like the the straps designed to allow glasses to hang down from the neck, but thinner) and a pully and line from that one is pulled down the back by a weak spring. Left / right motion of the head will not pull on this line, because the line between the frames will simply pull through the pully. Front / back motion of the head will pull the line.
Another line goes down the back from only one of the two ends of the frame. This line will be affected more by the left right motion than the up down motion.
Both lines are passed around the shaft of the encoders on a mechanical mouse before being terminated in a long, weak spring or a "take up" reel.

YASP: A simple and open protocol for building networks with small microcontrollers.
Protocol features:
* Adresses length: 1 to n bytes
* Medium access: CDMA/CS/NDA (Carrier Sense Multiple Access / Collision Detection / Non-Destructive Arbitration)
* Addressing modes: unicast, broadcast and multicast
* Smallest frame: 6 bytes
* Error detection: CRC16
* Physical layer: 1-wire "open collector" or 2-wire diferential (CAN transceiver)
* Current PIC implementation: about 480 words of code and 25 bytes of RAM (interrupt driven)
* License: LGPL
