I know you folks like to see practical projects. This is a DIY proofing box made out of a styrofoam cooler my sister sent me a ham in, a lizard heating mat, and a temperature controller I had laying around from when I was first trying out Sous vide before I got my Anova. Wanted to mount the controller on the side of the cooler but didn’t have any long screws that had the right head size. So I made a mounting plate from Draftboard:
Here’s the controller mounted:
On the inside, the screws I had were too long so I made Draftboard washers (3 stacked 1/8” pieces) that screwed onto the ends of the screws so I wouldn’t rake my arm on them.
The box is maintaining a nice 82 degree temp.
