And all that I just found this: https://www.atlas-scientific.com/kits/wi-fi-hydroponics-kit/

Not cheap but probably cheaper than what I've spent so far.  Oh well, need some hobby I guess

Well, now I've bought a EC probe.  But, didn't do the fully isolated daughter board.  And I think I'll go with that for both in the future.  Saves a lot of room.

An unexpected side effect of this is that a lot of churches have gone online allowing people out if the area to join in.

A couple of our church members attended a service at one of the Minneapolis congregations this weekend.

The nice thing about those EZO boards is that you can put a bunch of different probes and control boards on them and they are still the same interface.  Also learning how much hydroponics is a engineers dream. So much you can measure and account for if you want.

So for future expansion I'd add another of those.  I've already got additional 1-wire connections.

Priced it out and a 2 layer board is insanely cheap.  So may just get this one printed and work on V2 later.

so with everything that is going on the gardening project had to be scaled back. I wanted to build 4 raised beds, but only had time to build two - used cedar, and they came out quite nice, and it is a nice upgrade to what we had before. These are 8 by 2 feet. I filled it with a bunch of organic matter, compost and finally about 10 inches of top soil - lots of material. Found out that neighboring town has free compost, so filled my trailer with it. and then 40 bags of top soil

We planted a few days ago. The tomatoes, pickles, and sugar snap peas we grew from seed. Others we purchased. Also planted some zuchinni in the space I made a couple years ago. I will build the other raised beds in the fall so that they are ready for next year.

Getting a lot of water loss from my tomato box now.  The water is being sprayed on the lid and traveling along it to drip out.  Getting an air pump and air stone and going to replace the pump with that.

One the PCB front I'm debating whether to get the current board printed or go to version 2.



Looking to put another EZO port on there so I can either hook up a second pH probe or a different type of probe.  And going surface mount for some things.

So, going through a heat wave right now.  And every time I add water it raises the pH (while water is neutral pH I have a feeling my water might be a bit basic [/snap]) so it has been a struggle to keep the pH where I want it.  But, it also reduces the water temperature which is good.

Well, then maybe I'll send you the PCBs for soldering once I get them printed
