Hello,
After more than a year without brewing because of a newborn child and a job change i managed to build my electric all-in-one system from a 50 liter pot.
I used a bottom mounted 3 kw heating element i bought from AliExpress. Also the ball valve was mounted on the bottom of the kettle so that i won't need a dip tube (i don't like dip tubes because you need to keep a syphon going after the liquid level get's lower than the ball valve). With a bottom drain you can start draining even when you have as little as 1 qt of liquid in the lettle. I chose a round bottom element because i wanted to have as much volume as possible for the bag. Because i couldn't find one with very low watt density i made a false bottom to keep the bag for touching the element. Luckly i found a scrap piece of perforated stainless steel that had perforation only on half, so i made some slits on the other half with an angle grinder.
For the controlling part i used an Arduino Uno clone with the ArdBir code and i made an enclosure for it. The power line enters the controller box and splits in two: pump and heating element. For both the pump and heating element i used SSRs driven by the arduino.
This is the pot, very cheap ~40$ on a sale, it have a simple bottom, no aluminium insert or other thing the expensive pots have.
This is the heating element, next to a 2.5 kw one that i didn't use in this build.
The pot with the holes for the heating element.
And this is the highly anticipated hot water test!
