I hadn't noticed that. I'll have to view the video again. Morris will probably tell us what's going on. It is uC driven, and can count upto 30KHz. Its quite possible, that Morris is pulsing quickly (faster than we can see) from 0 to 1 to 2. Then more slowly from 2 thru 9. Reset to 0, followed by a slow 1 and 2. The cycle then repeats. The count following, 9 will be the 11th "carry" position, were the carry signal is generated. In older circuits for this tube, that carry usually also generates a reset pulse. To get better control, that signal could be routed to a uC input, and a separate uC output goes to the tube's reset input. Level shifting circuitry implied. Of course, only Morris knows for sure. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To post to this group, send an email to [email protected].
