Some dimensions of the joystick shaft, not drawn to scale. Measurements
were done with my eyes and a measuring tape, so they are not
perfect. (Click on the any of the pictures on this page for a larger view.) |

Top view of the joystick, looking down. The joystick handle consists
of a metal rod with a ball on top of it. Along the metal rod are 2 white balls
with a black rubber cylinder between them. Also, there is a little roller on
the end (see next pic). The joystick will only move around in a circle - the
circumference, if you will. |
 |
This roller is the bridge between the joystick handle and the
spinner axle. |
 |
The roller is placed into the rectangular uhh... spinner restrictor?
This rectangle is the only thing preventing the joystick from moving to the
center position. |
 |
Roller-hole to the left, spinner axle to the left. |
 |
The spinner axle on the other side. |

First, the bike-chain contraption is hooked up. This privedes a
little bit of friction, so that the joystick doesn't 'fall' into the down
position due to gravity when the control panel is at a slant. |
 |
Here is the first encoder wheel, consisiting of 72 notches. |
 |
Here is the second encoder wheel, consisting of to notches. This is
used to calibrate the joystick each time it has spun. |
 |
This is just more casing/protection. |
