    hello everyone
    Today, this is my first time post here, rather than replies. I am very happy to come to this forum to learn more knowledge of electronics.
    I share a project I've ever done, an AVR/51 ISP programmer, Maybe it is simple, I think there must be someone who need it. PCB and schematic is easy to understand, people who use it can also do some improvements needed. A few years ago, I made some when I learned AVR.
    Recently, a project need it, I have to make some.
    sch.jpg PCB picture below, it is actually more like a single layer board, bottom layer only has one line.

    I just sent my gerber files to Smart-prototyping who is in China to produce my PCB. and I will buy ATmega and the other components from Digikey. I will solder them by myself.
    After assembling the board, download the firmware program to AVR ISP programmer. You need an additional downloader to download to the programmer. I buy it from sparkfun(https://www.sparkfun.com/products/11801). In addition, the computer needs to install the driver.

    Thanks

    You could have bought USBASP for less than 5$ which would do the same job as that 20$ programmer.SparkFun is really over priced on some stuff...

    Yeah,many products in sparkfun,seeed studio or other Market Will be a little expensive.Some enthusiasts often make it by themselves.But I hope this project may help more people in need.

    Its nice project,but it really sucks that you need to have a programmer to make another programmer.Would been nice if AVR and PIC made MCU's with firmware already on the chip but then nobody would buy their programmers...

    Yep. I saw another programmer that uses ATmega8. But you need a programmer to program the ATmega8. So you need programmer to build a programmer. Nuts!

    When you need a certain mass-produced products, a download is not enough. Use a download can produce more downloader. Also, when you want to download integrated on your PCB, You can refer to this project.
