Hey everyone,
I just finished my brew stand and now want to add a little bit of automation to it. I've been looking for a simple and effective deaign and have had some trouble finding it.
My idea is to use single stage controllers(Johnson ranco love type) to only control a gas vaulve. The ignition source would be a continous sparker similar to ones used in this http://www.homedepot.com/Dyna-Glo-Pro/h_d1/N-25ecodZ5yc1vZ5fy/R-202223041/h_d2/ProductDisplay?catalogId=10053&langId=-1&keyword=Heater&storeId=10051. The sparker and pump will be on toggle instead of the controller.
Anyone see any issue I'm missing also a good sorce/recommendation on solenoid valves?
