The only components needed for the actual project is the esp8266, LED, current limiting resistor and a 3.3v voltage source. To get the 3.3v I ended u sing a AM1117 3 terminal regulator feed from a 18650 LIPO battery. I also added an option lipo charger to the board and a header to allow me to program the esp8266 board from a USB FTDI ttl cable.

Wiring can be a simple proto board or wire on a bread board like I did. I used a mix of wire wrap wire and some proto cable I had handy.

Here is the sloppy wiring.

Here is the front side of the board.

I was able to shoehorn the whole project into a large pill bottle.
