There are lots of proto boards for the AVR microcontroller, and lots of programmers. This post presents my approach, which features easy assembly, off-the-shelf PCB, extremely low parts cost and a built-in USB-based programmer. Circuit, PCB and firmware are all completely Open Source. Read on after the jump for details.

This post isn’t about the usual kind of dragon (if there even is a “usual” kind). The AVR Dragon is a gizmo made by Atmel, useful for programming their AVR line of microcontrollers. It’s relatively cheap (around US$50 at the time of this writing) and does many useful things. The specific application I’m going to talk about here is using it to “fix” parts when you’ve set the fuses in such a way that said parts won’t talk to simpler programmers. Details after the jump.
