“Most of the time Kelso is a great cat….However, he still seems to squeeze in some mischief despite a rigorous schedule that includes sleeping 18 hours a day. We need a solution and it needs to be high tech. A quick search of the spare parts bin in ‘the lab’ yields a PICAXE 28X1 custom programable microcontroller, a piezo speaker, a Sharp InfraRed Rangefinder and a AA battery holder.”

“About one month ago I had a request to write about break-beam sensors. So, here it is! Well, basically break beam sensor consists of two parts: transmitter and receiver. Transmitter emits light and that light goes to receiver. If that light beam between transmitter and receiver is broken by some obstacle, and receiver detects no incoming light even for a brief moment – it triggers an alarm.”
