    I want to build a binary counter that uses relays but I can't find a schematic does anybody have one?

    You can't find a schematic because they stopped doing such things around 1930. The schematics fortunately crumbled to dust before anyone could scan them.

    Why on earth would you want to do such a thing anyway? Electric bill too low?

    audio fanatics sometimes build fancy potentiometers out of a bunch of relays that are switched in binary.. I built one for my friend, but it was all done on a microcontroller.

    I want to build a really big and noisy binary clock.

    Are you making the clock out of 100% relays? Is using digital logic to control the relays out of the question?

    The clock can be made out of anything. I want to use the relays instead of a binary counter IC. I just want to show how comupters worked 70 years ago.

    Are transistor drivers allowed or we stuck with 12SN7's ?

    Not at all - I have a load of 717A's if you want to get the frequentlys up.
