After getting a roaring start to getting my system up and running for the season, the first time in three years, I decided that getting my elderly parents settled with health issues, my father going in to long term care, and my mother having major surgery I just couldn't muster the time to finish getting ready in time for the season.

I decided instead to work on the next version of my home made sap releaser and the controller that runs my system. To that end I designed a new bottom board for the PLC and sent it to PCBway. It should be here in a few days.

I added a pair of level shifters and a Schmitt trigger along with a DS3231MZ+ real time clock.

I'll post pictures as it comes together.
