Re: [avr-chat] cheap DIY programming cables: anything on USB ?

[swm]

The USBasp is a USB programmer supported in AVRDUDE since version 5.2.  The 
firmware is open source (runs on an AVR) as is the schematic.  Maybe people 
provide gerber files so that you can more easily make you own, and a few even 
sell their own designs based on the USBasp.

You may easily build your own or buy one already made.
