    req: schematic for flash-based PICStart Plus programmer

    picstart plus programmer rar Hi X, I will have to trace the board. I don't have a high resolution digital camera, but the photo will not really help now, because the back is mostly filled with copper pour, and a lot of detail is hidden from view. I.e. under the dip socket and the processor...

    req: schematic for flash-based PICStart Plus programmer

    picstar schematic I'm working on tracing the schematic off the PUM. It is not easy, it's a doublesided board, with tracks hidden under processor, and 40pin dip socket. When I am finished, I will post it. Regards, Whacko.

    Laser printer for PCB question

    Hi FoxyRick, When you try the acetone or other solvent, don't put too much solvent on and don't press down too hard. Make sure the copper is clean and oilfree. Let me know after your first try. If you have some hassles let me know, I will assist you, but I'm sure you'll get the knack of it...

    Laser printer for PCB question

    Coated paper is for higher resolution printing, I use the HP premium paper. You can get it at most stationary stores, and is actually meant for inkjet printers. But Yes, you can use it in lazer printers. It is relatively inexpensive and can really improve the time from artwork to PCB. It is...

    req: schematic for flash-based PICStart Plus programmer

    picstart plus schematic download I don't have the schematic. I was hoping someone do have it, but if nobody has it, I can buy the upgrade (PUM) module and do a schematic of the hardware. Then I can post it here. Whacko.

    req: schematic for flash-based PICStart Plus programmer

    18f6720 config bits picstart Hi stroma, I don't have the upgrade module, was thinking to make one up myself, I have the facility to do the TSOP on the required size PCB. I am from South Africa, the exhange rate to US$ and our currency is not good for me. The going price is US$29.99 which I can...

    req: schematic for flash-based PICStart Plus programmer

    schematics of picstart plus Hi PICUser, The upgrade module is almost like the "Basic Stamp" module and uses a PIC18F672 TSOP device which is on a board that matches the 40pin size of the 17C44 and just plugs into the IC base socket as you would plug in the 17C44. Can you get your hands on...
