In addition to the normal modding materials, this project requires three thumb-wheel pots and a three-axis USB joystick (a stick with a throttle or a stick with a twisty rudder). For these, I used:
- a Saitek Cyborg Graphite stick which includes a throttle providing the three axes: X, Y, Z
- Three 500k ohm Thumbwheel Pots (part number GN500TW-0EL) from www.guitarnucleus.com which cost me $3.95 each.
The project also requires epoxy putty (I use 3M QuikPlastik), some Velcro, and a nylon strap of some sort.
The PiggyBackTrim consists of four basic components:
The wheel pot housing which provides a mounting for the three wheel pots.
Circuit-board box which mounts to the bottom of the wheel pot housing and holds the joystick circuit board.
Wheel pot cover which is a small piece of plastic with slots cut in it that mounts over the thumb wheels.
Circuit-board cover which provides access to the circuit board and wiring for access.
In the next chapter, I will show you the how to prepare for building the PiggyBackTrim
