The Modification of this JDM-Programmer:
The Schematic of the PIC-Programmer:
The Print Layout:
I developed the print layout with the help of Eagle. Because I am not a professional lay outer I used the auto router. After some tries and errors I came to a practical solution for homebrewed stuff. My intention was not to build something for the industrial mass production.
The component side of the pic-programmer. The small holes have a diameter of 0,8 mm, the 6 big ones 3,5 mm. It is recommended to make the print of the layout with Eagle and the Eagle-BRD-file (Download here the jdm-layout.brd and the folienausdruck.brd, which is prepared for the print).
Feel free to modify and improve my Eagle files provided you don´t use them for commercial purposes. By the way here is the print-layout as a picture (layout-as-picture.gif). (http://www.janson-soft.de/pic/layout-as-picture.gif)The quality is not as good as a print with the Eagle-file. Don´t forget to resize the dimensions of this picture.Otherwise the components will not fit. I recommend the picture-viewer-software IrfanView.

The Software IC-Prog:
I use this pic-programmer in combination with the free windows-software IC-Prog. (http://www.ic-prog.com/index1.htm) This software supports also this modified JDM-Programmer.
My personal Experience:
pic-programmer.zip: This zip-file contains the entire web-page (www.janson-soft.de/pic/pic.htm) including all files and Eagle-files.
