Sous Vide 3D PID Controller - UPDATED

Description

Update December 2022 After going to the carnivore diet, I am using my Sous Vide so much now, I sometimes need two slow cookers going at the same time. So I made another controller. During my second build, I made a couple of changes and took a few more pictures of the wiring to help others. Cost to use: I have measured my hourly cost with a Kill-A-Watt meter for both of my slow cookers. A 270 watt 7-quart cooker and a 450 watt 10-quart cooker. It costs one US penny per hour to run either cooker at 135F. I will sous vide a 3 lbs chuck roast for up to 36 hours @ 135F. It turns out super tender. I modified the top part of the case to eliminate the center hole for the outlet. The hole exists for a wall plate and serves no other function. Plus, the cost of wall plate screws is just stupid. The two other holes secure the outlet very well. The PID bracket requires an M3 x 20mm screw or longer in order to secure the PID to the bottom section. I noticed the hex nut holes in the mounting bracket for the PID were too large, allowing the nut to fall out while securing the PID to the bottom section. Now, the nuts are held securely by friction while tightening the screws against the bottom section. Except for a couple of short pieces of wire, cut your wire lengths 15cm to 17cm in length if you are not sure about how long to cut them. This allows you to make the connections without excess straining. Previous Text July 2019 I have been exploring how to make the perfect steak, every time…
