The Atmel AVR Dragon is a new programmer for Atmel AVR 8-bit Microcontrollers. I obtained this little beast because my old AVRISP serial programmer was useless due to lack of serial hardware on my PC. The Dragon was quite inexpensive and readily available at DigiKey. It promised to not only provide ISP (In-circuit Serial Programming), but also JTAG, debugWire and high voltage programming for AVR device. It arrived in a very stylish red little box, but no cables, enclosure or anything else for that matter. After some searching I came across the Serpac H-65 enclosure. It proved to be a perfect fit for “my” Dragon.

Here it is, the first cut of my servo tester.
