ESP8266 BrewPi Display Box - US Plug

thingiverse

Nov 4 update - I made some further adjustments after constructing my box. I added some reinforcements to strengthen the box walls to accommodate the screws for setting in the power out plugs and additional support for the area between the plugs. I also enlarged the size of the opening for the screen as it was initially a bit too snug. I will be adding more BOM items to the list tomorrow. I decided to try building my own case for Fermentrack BrewPi Project. I aimed to keep the box compact while allowing enough space for components and wiring. I also wanted it to be able to screw together via bolts and nuts. This is a preview as I will be printing this out tomorrow but I wanted to share this with those who are interested that might want to follow along. I desired a large display on the front and clean cables coming from outside the back of the box. Fortunately, with some rotation of the main PCB board and the relay board, everything worked out. I've also been thinking about incorporating blue and red LEDs on the front of the unit so it's easy to see from far away whether or not things are heating or cooling. Yes, the display tells you what it's doing, but I can be clear on the other side of the room and not have to read anything if the blue light is on! If you like the idea of the LED add - let me know in the comments.
