I picked up this chip to create a nixie clock: http://www.allspectrum.com/store/6-digit-nixie-tube-clock-controller-chip-p- 501.html
it has tons of features which you can read about here (condensed feature list): http://www.allspectrum.com/semiconductors/ics/Neonixie/6DIGIT-NIXIE-CLOCK-CH IP/Neonixie-6-digit-nixie-clock-controller-options-v1.0.pdf I picked up an old nixie time code reader display (systron donner) from a surplus place (in seattle): http://www.w2hx.com/x/nixie/IMG_2113.jpg it was great because it had the nixies, controller chips, power supply and everything. I just had to wire in the chip (prototype here): http://www.w2hx.com/x/nixie/IMG_2511.JPG final soldered version here: http://www.w2hx.com/x/nixie/IMG_2721.JPG and the final product here: http://www.w2hx.com/x/nixie/IMG_2516.JPG only problem is, it doesn't (yet) take a 1PPS input. I've contacted the folks who made the chip to see if they would consider creating a version with 1PPS. But it does have a super cap that will let it keep time for something like 8 hours. regards 73 Eugene W2HX - _______________________________________________ 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.
