I am looking for a circuit that will indicate with leds, moon phases.
There are 7 actual moon phases (Each of the 4 lunar phases is roughly 7 days (~7.4 days) each but varies slightly due to lunar apogee and perigee).
I would like to do this with 6 leds, and the 7th represented by no leds illuminated.
Now I know that this can be done quickly and easily with a microcontroller, but I would like to give this a try the old-fashioned way...NO not with tubes, but with 555's and 4017's...and something along that line. It can be plugged in, so its not limited to a battery supply.
So whatcha say.....any help would be GREATLY appreciated.
Thanks
in advance
