New dekatron clock

[Grahame Marsh]

Here's my new dekatron clock. It counts mains (50 or 60Hz) down to 1 second and then down to the usual HHMMSS display.

No microcontroller! No AI used! The dekatrons do the counting and I've used transistors for the interstage coupling.  I Kept It Stupid and Simple...

Details are here

I hope to have a limited run of kits available later this year. 

Enjoy!

Looks great Grahame - the style of your Trigger Tube Clock III which I use as a heater from time to time :)

Best,
