Hmmm... I was aware of Groove Tubes and Aspen Pittman, but there is a lot of bad feeling out there: http://la-economy.blogspot.com/2011/11/aspen-pittman-groove-tubes-legacy.html etc. It seems that Groove Tube tubes were never made in the USA - they were Chinese, then selected and matched in the

[neonixie-l] Nixie clock with vacuum tubes

2012-02-06 Thread Cobra007
I was wondering if anyone ever attempted to design a nixie clock that is completely made up with tubes? I did a rough estimation and I came to about 30 ECC83 tubes to make a (24) hour and minutes display. That sounds like a realistic number, so perhaps someone has designed that already. Michel

WOW that is totally cool! It looks even better than what I would have expected! He said he's not running the clock all the time because of electricity bills :-) It looks like it consumes over 0.5kW!! Fantastic project, thanks for the link! Michel On Feb 7, 10:21 am, Adam Jacobs

Scroll down to the third group of links, titled All Tube Nixie Clocks: http://threeneurons.wordpress.com/about/ Are you including power supply and timebase in your calculations ? Actually, the ECC83 (aka 12AX7) is not the best choice for logic. The ECC82 (12AU7) or ECC81 (12AT7) would be better

Quite a bit of interesting technology there, especially the clock that is only made with neon bulbs, who would have thought that? Certainly not me :-) I came up with this question as I have an old batch counter that uses discrete transistors for it's BCD counters and decoders.

I am interested in this seller too. There are two Russian sites that look extremely similar and one of them has a weirdo CRT that I would like. I held off ordering because they would only accept direct cash via a service I have not used or know about OR via Western Union. I feel much happier

The BCD boards look to have 8 transistors arranged as four flip-flops.  This makes the decoders easy, as the flipflops have Q and not-Q outputs for each stage, so a simple wire-and lashup with some diodes will do the trick.  Cute construction with the long narrow board perpendicular to the
