We were always a little wary of bringing our Legos into the bathroom, but if you've got no such baseless fears, BattleBricks has published a handy how to on building one of those fancy auto-flushers you see in some of the finest washrooms worldwide. Using only parts from a standard NXT Mindstorms kit, Will Gorman rigged up a contraption that employs the ultrasonic sensor module to detect the presence and then absence of a bathroom-goer, and also features a dedicated button to perform a Rube Goldberg-esque manual flush.

DIYer crafts robotic flusher to save time, impress guests

Apparently, an artful fellow decided to do just that, and the resulting robotic flusher requires but one momentary press in order to successful flush any rigged toilet. And yes, the video (crank the volume!) is awaiting you after the break.[Via MAKE]
