ESP8266 BrewPi Display Box - US Plug

thingiverse

Nov 4 update - I made some other adjustments after I built my box. I added some supports to beef up the box walls to accept the screws to set in the box for the power out plugs and some support for area between the plugs. I also increased the size of the opening for the screen as mine was a bit too snug. I will be adding more BOM items to the list tomorrow. I decided to try building out my own case for Fermentrack BrewPi Project. I tried to keep the box as tight as possible, yet allow enough room for components and wiring. I also wanted it to be able to screw it together via bolt and nuts. This is a bit of a preview as I will be printing this out tomorrow but I wanted to get this out for those that are interested that might want to follow along. I wanted the nice large display for the front and I wanted the cables to be clean and all coming from outside the back of the box. Fortunately, with some rotation of the main PCB board and the relay board, It all worked out. I've also been thinking about incorporating a blue and red LED on the front of the unit so it is easy to see from far away whether or not things are heating or cooling. Yes, the display tells you what it is 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.
