[chbot] Cheap opto components

[Richard Jones]

I'm using optical sensors on my micromouse for wall detectors and rotation
sensors, hence my interest in these. The cheapest infra red LEDs and photo
diodes come from scrap mice. However if your supply of dead mice is running
out there are some components on Trademe that may be of interest:

L14H2 Photo transistors  840nm $10 for qty 200
F5E1  IR Emitting diodes 880nm $10 for qty  20
