Use a high-res Arduino web cam facing the wall of clocks and write OHR (Optical clock-Hand Recognition) code. That way its a single robust solution for setting it the first time, restarting it on power failure, resyncing after replacing a failed clock, or self-correcting after any mechanical glitch. You can also use the same video feed to show off the project live on the JPL web site. /tvb _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
