Here is my Dual Voltage BIAB Control

[ReddyK]

I have been lurking on here for several years and ordered a starter brew kit a couple of weeks ago. While waiting for it to ship I looked around the garage and thought I would scrounge up some stuff to control the element in the keggle. I found a temp control and a SSVR so, this is what I built. It will mash at 120V controlled by the temp controller and boil at 220V with the potentiometer. There are latching push button switches for the power, pump and element that illuminate when on. I added a timer and Volt/Amp meter just for fun. I chose the layout so I could easily add another PID and element in the future.
Thank for looking,
Steve

Great job! Looks like a nice panel, post up your whole system sometime.

Great! I'm utilising the same idea. 110v to the element for mashing to keep it from scorching, switch to 220v for boil. Thanks for the diagram.

Nice use of the heat sink

I thought this heat sink was larger and more attractive than the DIN rail ones and is still under $10.
