I like to think I’m fairly handy. I’m an electrical engineer, and I built the electric kettle and controller myself with a large pot, a few parts, and an electric hot water tank element. I plan to add a second control box to control the voltage and change the temperature in a more analog way.
That being said… there are many times and applications where I just don’t know where to begin. If I know how something works, what requirements and stipulations I must adhere to, I can usually figure out a way to build it. But here, I have no clue where to begin. I could easily do a second chiller placed in an ice bath, or a pump sitting in ice water, those are both good ideas that I wouldn’t have come up with on my own. I guess when it comes to home brewing equipment, I just don’t know where I should jump in.
