Master Clock Mk2

-

i have been building new arduino dcf77 master clock time now. clock uses 1" (25mm) green 7 segment displays, yellow lcd display, leds , bluetooth monitor time, decoding , clock pulses. clock drive various slaves , clock chimes.

mock of approx design


the clock has auto display dimming , pir detection turn 7 segment display , lcd back-light on , off when triggered entering room.




i have fitted blue tooth board can program/update clock remotely windows pc.  blue tooth module means can read clock stats , test pir detection android mobile.




the dcf77 signal decoded using fantastic new dcf77 library written udo klein. see site here http://blog.blinkenlight.net/experiments/dcf77/dcf77-library/

more details on clocks progress including test videos  here http://home.btconnect.com/brettoliver1/master_clock_mk2/master_clock_mk2.htm

completed master clock
