Since most of those cheapo movements are a simple single-coil motor, energized with alternating polarity short pulses, it would seem that there is no need for a "24 hour" movement. You can just have your micro pulse it twice the normal period, but with the same as normal pulse width(s). Check out the movement teardown in "lunchtime clock" at Instructables.com - http://www.instructables.com/id/Lunchtime-Clock/
The difference is that a 24 hr clock has a 24:1 gear ratio between minute and hour hands, and a 12 hr clock has 12:1.
If you're doing hour hand only, yep, any movement will do. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
