    Binary clock :)! Any one familiar with binary counters?

    if this is something that is going to be for sale wouldn't be easyier(and cheaper) to use the output from the 7 segment driver on a $5 clock?

    what should i do about computer rf emissions?

    i was thinking of building a linear power supply but i have to wonder about if just grounding a shield will be enough. if you are in a sealed box and throw a tennis ball against one of the walls what happens outside of the box, thinking along those lines  ??? lol

    Need RF transceivers in PDIP or DIP

    well what your looking for will be two chips, one that does all of the processing (thats now likely to be in plcc unless you can pull something out of older equipment), and the power rf stage can be bought as a module or smt flatpack device, you still might have to build a separate receiver...

    parts-express sells 3 conductor mic wire that might work.
