Hello friends, I have the photo of my product! If someone want to see, please, e-mail me! (The schematic was done with Protel 98, and the PCB was routed with SPECCTRA 7.1). I can reduce the price, if i send the board with only the PIC17C4X plugged, the schematic, the .bin file, and the D.O.S file! :) Miguel.
