Almost exactly a year ago, the prototype for the solar powered pump controller was installed and working. It was a hand wired and soldered on a perf board but it worked fairly well. But it is usually good to switch to printed circuit boards (PCBs) once the design has stabilized.

We actually printed these a while back, but as is usually the case around me, we had so many other things going on, this was simply waiting in the queue. We had a controller failure and rather than fix it, we finally upgraded to the permanent setup:

The two blue boards are the motor driver boards for the left and right pump motors and the red board in the BG on the lower right is the controller. The controller is the same board that drives the DC lights in the houses as well as the outdoor “smart light posts”. The black pieces of aluminum on the driver boards are used as heat sinks.

It is a bit cleaner, more modular (and hopefully more reliable) than the old layout:
