Not really a cnc project but wanted to share.
24 volt cabinet (ali) magnets.
EDIT 1: Ok, just ran my first workpiece. Good news it stayed where it needed to be, but the part got hot really quickly (no coolant) and that made the epoxy melt a little bit. Gonna try with coolant next.
Just thought I would share this and sorry beforehand it’s an AI story.
So this is my second year with the pool and last year ran it with with an automatic chem dispenser feeling happy as a clam that the water was clear, blue and no one died (as far as I know). The opening of the pool this year was a mix of Shrek and Grinch green but heck I did this last year so this should not be a problem, vacuum, shock, vacuum, etc etc. Then came the cloud.
So I work in IT and decided let’s see what we can do if we use whats available to us. Purchased a PoolLab 2.0 photometer (taylor kits are very expensive in europe and hard to get) started measuring and opened Claude AI (pro version). Created a prompt to tell it that it was an expert in pools, needed to check all it’s findings and chem advise against two different references and go talk to the cloud API of labcom to get all the readings.
Then the fun started. The advise was solid (double checked all the calculation myself) and the amounts that it was asking me to add to the pool was kinda off (2kg of chloor stabilizer for example, pool is 22,000 liters) and every time I asked it to check it would adjust some more.
I then started to think about the prompt and adjusted it with the following:
We then got somewhere and over the course of a week we started to get to the right values. But we (yes we, me and claude (I know this sounds stupid)) just could not get the wild swings of chlorine fixed, then out of the blue it asked me if I ever adjusted the automatic chem dispenser, Oepsie, fixed that.
It now works, pool is stable and looking good. A word of advise for anyone going this route,
- make the calculations yourself
- if you do not trust what the AI is telling you then triple check the calculations
- give it more information then you think is really needed, all of the stuff you are doing, Water temp, hardness (for LSI), shape of your pool, everything.
Looking back I think my journey was harder and longer then expected because the PoolLab broke (got it replaced), the redox meter of the chem dispenser was old and unreliable (bought a new one) and the worst problem ME and me thinking “Hey let the AI fix it”.
Just finished a small plate (stainless) for a hobby project, but i screwed up most of the holes about 2 mm (m5 thread) out of center. Would it be doable to weld fill the holes and redrill and tap them, or just scrap the part?
