The Automatic Toilet Flusher

This Project was submitted to Parallax by Joe Grand.

This project was started as a fun weekend task to solve a nagging problem with the toilet in our home - the need to hold the flush handle down while the toilet goes through its entire flush cycle. Apparently, this common issue could have been fixed by just replacing some components in the toilet, but I'm an electrical engineer, not a plumber, and I wanted to create a solution on my own terms.
