bobleny Posted October 18, 2006 Report Share Posted October 18, 2006 Im doing a project, and it's really sorta small, ... its a 4" cube..... I'm trying to build a binary clock for it.current time - for me anyways O o O o o O o o O owhere "O" is on and "o" is off. Does anyone have any ideas for this? It is running off of a small voltage probably 5 volts...I know I could build a 60hrz counter useing some 555 timers (yeah me and thoes 555s...) but i'd like something much more accurate.Do you know of a good way to do this? Maybe an integrated curcuit of some sort? Quote Link to comment Share on other sites More sharing options...
bobleny Posted October 20, 2006 Author Report Share Posted October 20, 2006 If, you don't know about ASCII binary, don't worrie about, it's really not needed at this point. All I need is a clock...Thanks :) Quote Link to comment Share on other sites More sharing options...

Maybe an integrated curcuit of some sort?A very simple and accurate way is through a 32768 kHz crystal oscillator followed by a clock divider.dt26_dt38.pdf Quote Link to comment Share on other sites More sharing options...
Ughadoo Posted October 20, 2006 Report Share Posted October 20, 2006 A 4060 is even better than the 4020 because you can use its internal ports to create the 32768 kHz, as in the circuit and datasheet below:CD4020BC.pdf Quote Link to comment Share on other sites More sharing options...
