I'm a Computer Engineer and I'm planning out an electric system on the cheap. At least, an Electric HLT and Kettle. (20 Gallon for the kettle and MLT. 15 Gallon for the HLT).
Anyway, I'm thinking the following: Put all the 220 wiring into its own enclosure and then put the control system (Raspberry PI or Arduino) into its own separate enclosure.
Two 1-wire buses would leave the control panel. One would be the measurement bus running out to the pots. The other would be the control bus which would run into the 220 V enclosure and would use a PIO chips and some support circuitry to control the SSRs.
I guess my goal is to isolate the "kill you dead" stuff from the control system as much as possible. I might even opto-isolate the 220V enclosure from the control bus if 1-wire supports it.
Anyway, just thinking out loud here. Anybody do something like this?
