I made a 5*7 and a 6*8 prototype design like this some years back but decided not to go ahead and make more of it as it became so large and heavy even with the Dekatrons stacked side by side, I wouldn't have anywhere to hang it in my apartment. I used both A-101 and GS10C in separate designs with complete control of all cathodes so I could light up any cathode I wanted on any of the Dekatrons by being able to pulse them with a negative voltage.
My idea was to use 4 or 6 of these displays to make up a clock but also a 4/6 character display with rolling text. One other factor which made me scrap this project was the power it would draw, nearly 30mA at Anode-voltage of some 450V for each digit plus the power for the logic and cathode setting control, at least some 20-30W for each digit. However, using the smaller A-107/8/9 Dekatrons might make a more beautiful design in my opinion, the only thing that might hamper the looks is the sideways protruding evacuation pip which makes it a little but harder to put them tightly packed side by side even if you turn them some 45 degrees and place the pip between them. I never bought enough of these small Dekatrons to be able to test it though. /Martin -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
