These useless boxes are everywhere online… so I built one from a KiwiCo crate. A useless box might look simple, but there’s a clever mechanism inside. When you flip the switch, a motor moves a lever forward that pushes the switch back down. On the return, the mechanism hits a hidden reset switch so the box is ready to repeat the process. It’s a tiny robot designed to do exactly one thing: turn itself off. If you want to learn more, check out ‪@KiwiCo at kiwico.com/YTShorts. #kiwico #uselessbox #science #engineering
