Thanks! I've added one movie showing the clock running 24 hours in just about 100 seconds, clocked from an oscillator with approximately 1 kilohertz or so, with all glue logic for a 24 hour clock in place: https://www.youtube.com/watch?v=rnNHhLAY64U /Martin On Monday, 17 August 2015 18:47:54

Yes, direct drive, nothing in between. The design is just like the schematic I published here on the forum some time back. The only addition is a few diodes to make it possible to count forwards/backwards plus some pull-up resistors, but the main design is identical. To connect each stage to

Neat ! I assume those polyatrons are directly driving those nixies. On Saturday, August 15, 2015 at 3:30:54 PM UTC-7, Dekatron42 wrote: Hi all, I've just published three new videos on my Polyatron clock prototype, just the driving stages and some carry/set logic plus forward/reverse running
