"The induction receiver shown below is very sensitive and can serve a variety of purposes. It is excellent for tracing wiring behind walls, receiving audio from an induction transmitter, hearing lightning and other electric discharges, and monitoring a telephone or other device that produces an audio magnetic field."

"What does one do when designing a power supply? Well, build a power supply tester, of course. One of the simplest things to build is a constant current load. This will allow for testing of the endurance of the power supply, as most of the designs out there are using slow components."

"Dan suggested building a robot that would flush the toilet at timed intervals throughout the day. In my mind, calling something a ‘robot’ sounds like a sophisticated, possibly sentient being that can do your bidding. But simply put, a robot is a machine that can be programmed to do tasks, like flushing a toilet. An automatic kitty toilet flusher sounded perfect!"
