Re: Rigging sensors
Try a search on optical switches. Perhaps that will turn up some other alternatives other than garage door switches. They may require some additional circuitry in order to make them work. 30 cm is a long distance for IR switches. The cone of transmission will be pretty wide at that wavelength. Expect some false positives with the ball construction. Look for those that operate in the 5-12V DC range.
