I dissolved in as much as the water would hold, I can't remember exactly what ratio it worked out to. Pretty sure I was still drinking back then, so there's that.....😛........ probably accounts for the broken tap too.... 🙄

So far it takes about 30 minutes for that tiny reservoir to empty. It may well be worth gluing a tall tube in order to get the pressure up.
Or a tall tube with a flange that can be clamped to the aluminum part so that then an air valve at the top can use compressed air to push the liquid through.
Possibly even a two step process where a tiny bit of lye is allowed to dribble through a number of times. Granted that would likely damage the threads a tad but more likely dissolve the bits of aluminum that have jammed the tap.
Between lye and the alum it might loosen it enough to be able to be screwed back out.

Status update. An hour or so later and there is no longer fluid dripping through. Time to take it out and blow some air through it and maybe poke some really fine steel wire through to dislodge chips.
Or just give up and replace the 3D printed J2_ARM with this metal one and continue with wiring.
You haven't cnc'd it ? Sheesh.

Well... more like what shall I use for the timer. I have an extra relay output to run a pump on HERBUS for the seed tray. With Home Assistant it's trivial to tell it to run the pump for 0.5 seconds every 1/2 an hour. But then I have to pull it from the wall open the back, run some wires. way too much work.
I can use the AR4 software for the Aruino Leonardo and program the ROBOT sofware to run a loop that runs forever with a 30 minute delay and then relay on delay 0.5 seconds then off and back to step 1. But that ties up a PC etc.
I could program an Arduino to drive a relay and do the time loop.
Or use one of these and add the timing loop. About as much work as the Arduino. But it has 12V relay drivers that could run the motor directly. So less wiring.
See Don, I told you.
What IS one of these John?
One of the products I make for a customer.
The small white one in the back is called an Expandable Management Unit (xMU) that started life as an RMU or Rings Management Unit. Two of them talked via USB to a PC which ran the show software to control these:
Automation Artisans Inc.
Finally the black box there is a PCM or Power Control Unit. It's a DC-DC converter power supply that takes 24V lithium battery input and creates 24V plus 12V (total 250W). Monitor AC and DC charge voltages and is responsible for turning the system off when battery SOC drops to the cutoff point doing a clean shut down.
They talk via CAN bus to each other and also external modules like motors, inclinometers, battery chargers, Battery Management Systems.

Yes this is random- is the 42 in reference to the book?
That's what I said
Something about a hitchhikers guide book, and the number 42
Made no sense to me either
Ah! I thought everyone knew this... At the end of the book "Hitchhiker's guide to the Galaxy" the main character discovers that "the answer to life, the universe and everything is the number 42". Now the author of the book denies it but I don't believe him. Best way to keep the mystery alive and sell more books perhaps.
Anyway. A=1, B=2, C=3 ... Z=26. Now add up the numbers assigned to the letters "MATH" and you get 42. So in fact "the answer to life, the universe and everything is MATH".
There are conflicting opinions on this if you want to google it all.
But the number of items on my list of things to do is 42. Anytime I finish a project I take it off the list and then add up how many are left. For some strange reason the total is still 42. So maybe the number 42 actually means MAGIC.
Ah!
No, that's one author I've skipped, for whatever reason. I'll probably finish off Bryce Courtenay then go look for Nelson Mandela or a Canadian confederacy book, then Douglas Adams.
The librarian said I'm too stupid for some books so I'm trying to pace myself 🙄
For those who want to know more about 42, the answer to everything, here is a cool article written for Scientific American about it.

Like @jcdammeyer, my project list has 42 main items that never seem to go away, but I also have sub projects like 42-b-IV-229-F. So its a discrete number of 42 projects with an infinite number of elements.
For Math Fans: A Hitchhiker's Guide to the Number 42
Here is how a perfectly ordinary number captured the interest of sci-fi enthusiasts, geeks and mathematicians

No one is too stupid IMHO. Some of us just take longer. I'm rereading (skimming more this time) "Fantasyland" by "Kurt Anderson" published in 2017 and to not get into politics, (much) even more relevant now. It's non-fiction.
A good fiction, yet somehow appropriate for the times, given the heat dome we had here a few years ago, is "The Ministry for the Future" a novel by "Kim Stanley Robinson" from 2020. He also wrote the Red Mars, Green Mars, Blue Mars series. Real Sci Fi.
I'll look for your Anderson book. JD Vance wrote a book, Hillbilly Elegy, that I read long before I knew he was in politics.

Was she your third grade teacher at some point? 🙄

Did you read it on the couch?
No, but I've got a good one about my grade 10 English teacher 😀
