If you are having any problem with AVR microcontroller burner ....
Not able to get one....
If your PC have a parallel port...
then..
NO need to buy any STK500 or similar....
just....
make your own programmer.....

using BSD programmer.....
Just connect pin no..
Parallel Port --- AVR
7 --- RESET
8 --- SCK

10 --- MISO
18-25 ---- GND
Software Used :: AVR dude windows based programmer
b) Use a buffer / driver for the programmer (STK 200 dongle)
http://www.lancos.com/prog.html
(click on above link for the larger image of circuit)
only one IC 74HC244 required
the circuit can be made on a bread board... or on normal PCB
Software used :: PONYPROG on the same website www.lancos.com
* circuit of AVR STK200 dongle is also available on www.electronicsforu.com
or use google search for old Kanda or ISP circuit or STK200 dongle
