Following on from the use of the 8-tooth timing wheel in the 8479 bar code
truck, which varied the rev sound, I used a 4-lobe Technic Knob Wheel
http://www.bricklink.com/catalogItem.asp?P=32072 with a touch sensor connected
to a bar code unit to produce a 'chuff' sound for a large scale steam engine
(approximately 1:8.4 scale of a narrow-gauge engine), with four chuffs per wheel
revolution. A second bar code unit detected the buffer touch sensors touching
the end stop in order to stop, pause and reverse the drive motor.
At first I thought the 8-tooth timing wheel might not move a touch sensor by
enough to be useful, so I kept it for the bar code unit's light sensor, but I
might give it a try with a touch sensor in another application.
8-tooth timing wheels are also very useful for holding eight 3.2mm-thick round
parts. I've tried them with flex tubing and also the 8 optic fibres of the unit
from the space shuttle.
