I see the "T12" stations are quite popular now, and what I found fascinating was this thread here: https://www.eevblog.com/forum/review...p)-conversion/ - which includes an analogue control circuit for the T12 cartridges.
Since I'm not really a fan of devices powered by undocumented microcontrollers, I'd rather have an analogue version - so much easier to fix (and cheaper).
Has anyone used this circuit? One user in that thread says it works well and many people have built one - but so far as I can see, most people just seem to go for the OLED etc versions with more flashing lights.
I'm quite tempted to build this controller and get a nice aluminium "Quicko" T12 handpiece for $20. Seems like a great deal - if it works.
