Introduction: The Cheapest ESP8266 Programmer!
Hi folks, now I'll teach you how to make your programmer to the ESP-01 and ESP-201, (perhaps serve with other models) using an Arduino UNO, a few cables and optionally a button and a slide switch, in my case I use them because I had available, with this programmer able to upload the Arduino sketches and any other firmware (AT, LUA, Espruino, etc).
Step 1: Okay, Let's Start, First Do the Following Circuit.
Optionally if necessary can place a 100n capacitor between Vcc and GND and if you're a fan of security, you can put a divider or Logic Level Converter voltage between RX and TX.

only one minor err I spot, on the fritzing drawing.. note you have a wire going from vcc (the 3.3V power rail) to the CH_PD pin, and the reset switch, and the other side of the switch to GND (causing a dead short when pressed, to the 3.3V supply.) I think you meant to create a red wire from the CH_PD to VCC, and only a single wire from the open end of the switch, to RST. Otherwise, that's going to be brutal on the 3.3V regulator

i'm using this dev board that i made myself for esp-12. dont need arduino but still you can program it with arduino software via an ftdi.

This would have been cheapest if someone has Arduino board already.

Thanks dude and the best, the Arduino and ESP-01 are independant!
