Atmel AVR programmers
A pair of AVR JTAG programmers for hobbyist.
There is a lot of AVR programmers around the web. Let me show some of them:
The first one (I'm actually using) is the, created by Kosta (in Czech). His construction fits into the CANON9-CANON9 plastic adapter. All you need for construction (PCB drawings, firmware) is available directly from . You can buy it as kit or as finished device too for costs about 30-35 EUR. is compatible with AVRstudio and is suitable for all AVRs with JTAG interface (ATmega16 and higher).
The second one I found a short time ago is theby Andrew Leech. It combines JTAG and ISP interface, so it can programs not only JTAG-positive AVRs, but the ATtinys, smaller ATMegas and AT90s too. His construction utilizes the FTDI FT232R chip, so you can connect to the computer by USB interface. Author provides all necessary things you need to construct on his pages too. If you want, you can buy finished product for 55 USD + postage.
The third one is USB friendly too, but it hasn't the JTAG, just the ISP. It is compatible with the STK500 and its name is. This construction is "open-source" and is provided by Tuxgraphics.org. It is possible to buy the kit (need to be soldered) for 22 EUR (29.50 USD) in the .
