Cheap USBASP Sticks for V-USB Development

A while ago I ordered a couple of cheap USBASP sticks. They are to be had on Ebay for as little as 2,50 € including world wide shipping and meant to be used for programming AVR microcontrollers. The programmer itself is based on an ATMega 8 controller so one of the sticks can actually be used to update the USBASP firmware on the other one. All it needs is shortening JP2 on the board to be flashed.

But that is not even best part: the USBASP firmware is based on the open source V-USB driver, meaning these sticks can easily flashed with any other firmware using the same driver. So, they make for a cheap, complete, and easy to handle development platform for USB projects like the IR receiver introduced in an earlier post.
