Pool Pump Controller – in Action!

Summer is finally here, and the hard work on the pool pump controller is starting to pay off. It looks like most of the bugs I ran into last year have been ironed out and it is working like a charm. Except when it doesn’t – but it quickly recovers.

In the video below, you can see the setup and a demonstration of its operation. Unfortunately, there is one more bug – when exiting high speed mode, the controller resets, but in 30 seconds it recovers and picks up where it left off. I think it is an EMP burst affecting the controller as it is in the same metal box as the relay.

A second gremlin sometimes affects the display on speed change, but the display refresh code eventually cleans that up.

For those needing a refresher, here is the initial writeup, and here is an update providing more info on the build, including code and schematic.
