Yes - to Michail's point and also to those who've emailed me asking the 
same question, there are a handful of Dekachron kits available now. Several 
different options from a full kit including tubes and the enclosure in the 
video down to PCB and components only. If anyone is interested or has 
questions, send me a private message so we don't clutter the group chat 
with that stuff.

Re: [neonixie-l] Dekachron - new dekatron clock

2021-05-16 Thread Jon 
The design needs the tubes to run at 4kpps to get all of the persistence of 
vision effects to work smoothly. In the video you're looking at ETL GC10B 
and GC12/4B - the clock auto-configures itself to work fine with any mix of 
those and equivalents (GC10/4B, CV2271, Z303C) and Sylvania 6802. Although 
I've described it as a H:M:S display, actually you can assign any function 
(including cool visual effects) to any tube in software, so it's very 
flexible.

The common Russian neon dekatrons (A101, OG4, OG9) won't work however, at 
least per datasheet, as their max speeds are not high enough. And the octal 
base tubes have a different pin-out (but that's a trivial change, 
obviously).

Jon.

What speed are you running the dekatrons ?
