ESP8266 Matrix Display Case Remix

I wanted to use this great thingy from wabbitguy to make a display case for a WiFi scrolling message display. I modified this to incorporate a buzzer to announce a new message or just to be annoying. A passive buzzer fits into the base of the horn and connects to the nodemcu module.

I modified the back cover to pop into the case without screws. I removed the back screw bulges on the case, as well, as I was having problems sliding the mount into the case with all the components installed on the mount. I also added a 12.7mm hole to put in a latch button for an on and off switch.

I also changed the mount a little as I ruined my MAX7219 module trying to screw it into the original mount (totally my fault). This modification allows you to just set the module into the slot at the front without any screws. As in the original, a screw on the bottom secures the mount to the case. I also had to mirror the mount to install the nodemcu on the other side which was more convenient for me. Easy
