This is a case I made for the https://deauther.com/ 

This case is designed for nodemcu version of esp8266 and 0.96 oled screen there is also plalce for charging module for lipo 3.7v which boosts the voltage to 5v for esp. Esp is powered by this module via the vin pin. I recommend that your 3.7 battery be as small as possible because it's very tight inside mine comes from old drone. Button on side is connected to charging module with this button you can turn on and off your deauther. Below is the list for all parts required in this project 

I also recommend gluing the buttons with super glue and the screen and charging&boost module with hot glue because its tight inside its nice to desolder pins from screen and solder cables directly to screen soldering pads
