1Step 1
I have built several of these development boards. The contstruction technique and enclosure is up to you. there are no critical parts or tolerances. Most of my electronic parts came from various ebay suppliers.
I used wirewrap wire but any small guage hookup wire will work.
The case was one of many I purchased when Radio Shack was closing stores. You can build these on a bare board or put it in some enclosure.
The switches I have had for years and were pulls from various projects.

I used a USB FTDI serial port board. Plugs into a stadard USB port and provides recevie and transmit data pins along with power and ground. This specific model also provided 3.3v but didnt have the current capacity to power the esp8266, so I used the 5v line and an external regulator to get the 3.3v.
You can get similar units with mini or micro usb ports. Use the configuration that meets your needs.

Here is my chicken scratch schematics I started my work from.
Here is a bit cleaner version of the schamatics. The ftdi headers users the 5v line (red), RXD line in orange, TXD line through the voltage diver in yellow, and Ground.
The two switches are used for power and setup program mode with the LED connected to the GPIO pins.
