how hard or simple whould it be to build a binary clock,,,is there any schematics available?
binary clocks have caught my interest...<p>also seen a clock once...it had digital display...with 60 leds in a circle...one by one they lit up..then after 60 sec,, they went out one by one...anyoe seen such a clock? i think i seen this one in a subway in either austria or germany.....whould love to have one too...any ideas,,,

A binary clock would have to have a lot of digits to tell the time. I would go the other way and make a 1 digit clock. 24 hours and 60 minutes per hour give you 1440 clicks on your clock. That is, your clock could have 1440 minutes around it. In binary that is a lot of digits.<p>On second thought, don't do this.

I just searched google. There seemed to be alot. This looks like a good one.

Dacflyer de jetflyer:<p>Keeping with the binary readout ,the technique to use on the readout format is to tier them in decades. This ends in a quick readout capability, as compared to a long linear laid out display.
For a very simple schematic using common easy to get parts ,see:

For the digital clock with binary readout……that should look good with some of your heavy industrial strength LED’s….but also don’t forget to see other clocks at the main home page :

thanks for the link ed...lots of neet stuff there
the binary clock looks simple enough..whould be great if i could find a foil pattern or a premade circuit board,,,just add my own parts,,found a kit,, but they want over 50,00 for it.. BAH !

To do the perimeter light (600 LEDs, I would just use a buncha shift registers arranged in a long "bucket-brigade"; all clocked at 1 cycle of course, and a divide-by-60 flip-flop providing the everyotherminute effect (odd minutes get a "1", even a "0")...
