So the application is reflux distillation. The column is open to the environment for safety purposes. At steady state operation any heat fluctuations produce excess vapor which is vented off as waste. This is because there isn't a reasonable way to modulate the cooling performed by the reflux...

That's a fair point. When I was using an arduino for this I had to keep it pretty well isolated from ...everything lol. 1-2s period is too long. I've tried it before when I was just testing with a mechanical relay, it caused noticeable fluctuations and prevented anything close to steady state...

My first time seeing the name SSVR, but from few minutes of googling it looks like that's what I have (just built from discreet components). That's a good idea about using a digital pot, that hadn't occurred to me before. It would definitely simplify things for me. Seems like you're in...

Does anyone know of a plugin for using a TRIAC (phase control)? Essentially I need to use one pin as an input from an optoisolator (this tells the Pi when the AC sinusoid is above or below a threshold voltage (so for me in the US it sends pulses at 120Hz). After seeing a pulse the Pi outputs...
