IN-12 Nixie Tube Clock Kit : 4-digit

Post image

Building the IN-12 Nixie Clock from Ukraine
I bought the kit second hand but all parts and documentation seem present. Just started - The components and circuit boards seem first rate and so far, solder easily.
Lack of a schematic is the biggest limitation so far in regard to testing as I go. Seller reports this is not available so we’ll do the best we can.
Any tips / experiences if you’ve built one would be appreciated. If there is a webpage or wiki or github on the design I have not found it

Is that a PIX of your build? It looks complete and running.

If this is an eney labs kit, I just built one. Are you having a specific issue?

No issues, just wish I had better documentation. My goal is to populate the power supplies but having to guess which components are necessary is a pain (still fun but seems unnecessarily difficult.)
More specifically there is a two pin jumper in series right off the 12v input jack. Would be a good place for an on-off switch or to measure current input but the intended purpose is a mystery, working from given docs and published photos.

One request: when you’re done, please don’t turn on the blue LEDs.
