A rundown on a neat digital clock boasting vintage parts in design. Designed and built or provided as a kit in the USA, this gem is a show piece. Visuals include an animated frequency scaling section for the time base, binary counting and of course the Nixie tubes. The tubes are the IN-12A Soviet Nixies with the upside down "2" used as a "5". As I played more with this it turns out that when using the setting buttons, they are intended to be held and the settings then change at 1 Hz increments. So the user should not pulse the buttons but actually hold them for desired changes.

Very bealtiful , clock and pcb, congratulations ...what transistor you use to drive a níxie tube?

Thank you. Very happy to have obtained it. The transistors used are MPS-A42 NPN transistors to drive the Nixies.

Nice find, it's definitely an eye catching clock! What's the power consumption? It looks like some ICs are 74LS parts, and others are 74S or 74F

Thanks, it is a nice piece. I did not check out the power draw.

The label on the bottom right makes it slightly less appealing for an international audience, but I suppose we can just appreciate the overall design and forget about that detail

I would image there was a time where that would be looked upon as greatness but in our current political climate, it could maybe considered embarrassing. Our ship may be sinking. The confused are the ones that are heard in the spotlight and are at the helm and the captain is not the one in control. The ones in control drag everyone in the way, thru the mud and feed us incomplete truths.

@@JIMO415 What a beautiful timepiece. As someone who is part of the international audience, I don't think it's my place to speak on behalf of everyone outside of the US. But I for one am heartened to see the label on the bottom right. Thanks for sharing!

Nice see through case, Do you by any chance work on these type clocks. I have one that is based on the MM5314 chip that seems to gain 10 minutes per day.

Hi Greg, I do like the "see the works" look too, thanks. Yes, I do collect and work on them especially the MM5314 based ones. Do you know what your clock uses for a time base? Is it line sync'd or does it have a crystal oscillator? If you want, you can leave me you junk email here or a way I can contact you to move forward or we can do it here. Jim
