I see a lot of people going after control systems each in their own unique way. It's very homebrew-like but I'm thinking there may be an opportunity for a few of us to get together and develop an Arduino or similar self-contained controller that anyone could build for a relatively low cost.
I have to admit, I considered developing and selling such a solution but UL listing and potential liability scared me away from the idea. Instead I'm thinking we could develop the code and provide a walkthrough for anyone to attempt at their own risk.
I think a device could be built for close to $125 including:
Arduino Pro Mini 5V $20
USB Cable $15
20x4 Serial LCD $35
(2) SSRs $25
(2) Temp Sensors LM34 $10
Project box, LEDs, switches: $20
Some sketches of screens I'm invisioning:
