I was 13. I also build one of the seismograph designs just for fun. I did not build the quartz reference clock design in the book but used the idea to motivate me to add a quartz reference to the 60Hz inverter I built from the ARRL handbook, using a bunch of DTL flip-flop dividers, to drive a mechanical clock with a synchronous motor. This was in 1969. So I guess that delimits the beginning of my time-nuttery. -- Brian Lloyd Lloyd Aviation 706 Flightline Drive Spring Branch, TX 78070 [email protected] +1.916.877.5067 _______________________________________________ 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.
