How to Flash an 20A Hobby King ESC with simonk Firmware
In this video, I go through the steps I used to flash a cheap Hobby King 20 amp ESC with the simonk firmware. The simonk firmware is a must to get the most out of your multirotor! I like them as they are cheap (but don't come with any bullet connectors) and have awesome performance after they are flashed.
The video goes through the whole process from what firmware to use and how to make the pins/cable to connect to the computer.
Search for "USBasp Programmer" on google or ebay for the usb programmer/cable required to do the flashing.
This is the command line I used for the flashing:
avrdude -c usbasp -p m8 -U flash:w:bs_nfet.hex
Below are the links I mention in the video:

The programming pads on the ESC
See the video for how to make the wire to interface with the programming pads.

The homemade programming pins, made from some Cat5 Networking wire, you can use any wire but it should be wire that is stiff. You can see I used a blob of hot glue to hold it together.
