    Question Uir?

    I have been trying to build this uir ( http://people.a2000.nl/rwvgesse/FixF...?downloads.htm ) mainly because it uses the pic16f84 which I have here at home to use but have had no luck with those plans. Does anyone have any sites witch show how to build a uir with the pic16f84 (preferably also using the same parts on the sites so i dont have to buy more things).

    Thanks,
    Greg

    The only thing I can think of is to remove hight frequency harmonics from the crystal. I don't think I've ever seen them used with a crystal timer before. I recon you should be able to do away with them.
    And you say people actually pay money for M$ Windows?

    Total re-design underway: on the whole progress is very slow as the car is taking up too much time :)
