No it is not a high voltage programmer Try AVR Doper. A simple easy to build high voltage parallel avr programmer. MicroKid

I had build the following programmer. http://www.tuxgraphic.org/electronics/200510/article05101.shtmlRecently I saw that there is a new version. http://www.tuxgraphic.org/electronics/200705/article07052.shtmlSo I started to build it... Later I discovered that I had no FTDI chips left... I was bored sitting without doing something so I fused the following projects... http://www.tuxgraphic.org/electronics/200705/article07052.shtmland http://www.recursion.jp/avrcdc/The result was this circuit The combination above wont work unless we make some changes to the code running inside the Atmega8 / 88 . The code can be found here. After decompressing the file we are locating the file uart.c. We open it and locating the part bellow // baud=7=115.2K with an external 14.7456MHz crystal // baud=9=115.2K with an external 18.4320MHz crystal unsigned int baud=9; We are chancing the unsigned int baud=9; to unsigned int baud=119;. This change is necessary in order to change the uart of Atmega8 / 88 to 9600 bps witch is the maximum for the Attiny2313 part of the circuit. With the command make we are creating the main.hex which we are going to load at Atmega8 / 88. If we don't have any other programmer we can use avrdude and a very simple programmer to load the codes to the chips. The code for Attiny2313 can be found here. The existing cdc2313.hex file can be used as is for programming ATtiny2313. The programmer works fine under Linux and Windows with avrdude and Atmel AvrStudio 4 under Windows. For those that can't handle smd chips like FTxxx and doesn't want to order the pcb it is a good solution. The programmer is a bit slow because of the 9600 bps. All tests were made using ArchLinux with gcc-avr 4.1.2; avr-libc 1.4.5; binutils-avr 2.17; uisp 20050207 and avrdude 5.5. For the testing in Windows; I used Windows Xp Sp 2.

thanks wellnerson1... I had searched over the net for programmer but could only find one where we had to have 89C2051 or atmega8 chip programmed with the provided firmware somehow before burning into 89S52. I cant get that done so i'm searching for the simpler alternative.Any suggestion?
