Dekachron - new dekatron clock
Jon
The discussion in a recent thread about different glow patterns on a dekatron reminds me that it’s high time I shared with you my latest clock… This is Dekachron, a 3 tube dekatron clock.

Just to explain what’s going on here - Dekachron uses a rather different way of displaying time than the approach used by most dekatron clocks (eg those by Ronald Dekker and Andreas Reinert). Typically one would have tubes arranged in pairs like a nixie clock, indicating the hours (tens and units), minutes (tens and units) and maybe seconds too. The position of the glowing dot on the dekatron display denotes the digit value. So we’d display 08:25 like this:
However, Dekachron uses its dekatrons as a series of analogue clock faces, one for hours, one for minutes and one for seconds. On each one it lights up a sector of the circular display that corresponds to the position of the relevant hand on a traditional analogue clock. So Dekachron displays 08:25 like this:
It's surprisingly easy to read with a little practice, because it taps into how you learned to tell the time as a child. Displaying the time in this way allows us to get a H:M:S display with only three tubes and also opens the door to all kinds of funky visual effects, some of which are shown in this short video (https://youtu.be/5LtvPJZnqM8).
If anyone is interested to build a Dekachron, a few kits are available – PM me.
