I'm so infatuated with these machines that I've been working on designing my own version (using parts available at Mouser/Digikey) for close to a decade.
Unfortunately I've been unable to maintain a decent work/life balance due to the high cost of living. As a result, I honestly die a little inside each time I see an article posted about them.
The last update was in 2013, where I completed the EHT "popstart" circuit (to replace the expensive retractable electrode, and allow the use of a standard TIG head): https://www.youtube.com/watch?v=Y4c5Le2kT6w

Some day I'll complete it!
