Lovely! My first exposure to TTL logic circuits was through building a Nixie Clock. It looked nice, and certainly impressed my college dorm-mates, but didn't keep very good time. Very sensitive to power-line noise and dropouts, and I never got the seconds and minutes counters to reset to zero reliably on the count of 60. Now I know better, but I'm not sure that I want to go back to using 1970s technology.
Except, of course, if I could find a nice set of nixie tubes at a reasonable price, and a set of sockets and a transformer for the high-voltage supply ... ! The controller chip looks interesting, and certainly has a lot of desirable features. It may be easily adaptable to different display types. I agree on the lack of a 1 PPM input, and I would prefer a 10 MHz TCXO timebase over the standard 32.768 kHz oscillator. -- Flemming Larsen ________________________________ Fra: W2HX <[email protected]> Til: 'Discussion of precise time and frequency measurement' <[email protected]> Sendt: 19:13 onsdag den 8. juni 2011 Emne: Re: [time-nuts] locate 6 digit digital clock [snip] regards 73 Eugene W2HX _______________________________________________ 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.
