[Thomas Clauser] had his basement flood last year when a hurricane swept over New England. The problem with flooding or leaking water is that chances are you won't notice until it's too late. He decided to protect against this in the future by building his own leaking water detector. It's a simple device that sits on the floor of his basement and triggers an audio alarm if water begins to cover … [Read more...]

Radar detector tester

F5CIV2QG1ZGO8OS.MEDIUM (Custom)

[Blacklight99] made this cool tool. It is a tester for those radar detectors that people keep in their cars. Though this seems like it would rarely be a tool we would need, it's an interesting project. Some speed guns that the police use have a "stealth" mode that makes them invisible to some detectors. This tool can tell you if your detector is vulnerable to this. While this really is just a … [Read more...]

Arduino muon detector

[Sebastian Tomczak] was borrowing a homeade muon detector from his friend, and managed to hook it up to his computer through an Arduino. The detector itself uses 3 fluorescent tubes to detect radiation. Three separate tubes are used in order to filter out terrestrial radiation; cosmic radiation will fall in-line with the tubes and pass through at least two of them, whereas terrestrial radiation … [Read more...]
