I MOVED TO PRUSAPRINTERS.ORG, PLEASE VISIT MY PROFILE THERE AND DOWNLOAD THERE! THANKS!

https://www.prusaprinters.org/social/229741-wizeus/about This is a case for a PID-enabled reflow oven controller based around an Arduino Pro Micro. Here is the Project's GitHub (for code and the PCB design): https://github.com/0xPIT/reflowOvenController Inside there is room for an 1.8" LCD display, one rotary encoder with built-in button, a separate button (I use it to reset the MCU) and a 3mm LED (I use it to show when the SSR is getting turned on by the MCU). The main case has a mounting surface on the bottom, which should allow for making custom mounting solutions, depending on what you need. I used the flexible arm of an old lamp to make the controller freely movable. USE AT YOUR OWN RISK! BE CAREFUL WITH HIGH / LETHAL VOLTAGES! All of the high power / high voltage electronics should be mounted inside the original case of the oven. Be 100% sure to use an isolated power supply for the Arduino etc. and make sure to connect any exposed metal to protective earth! I decided to route a signals to the LCD and the Buttons etc. through the arm an leave the Arduino on the PCB. If you build this project and want to give me something back in return, I'd be extremely happy to see a post under "Makes"! :) Here is an example for the display: https://www.aliexpress.com/item/32263827143.html
