Re: [neonixie-l] Re: B-5972
It's possible, they did stamp some NL-5991s as "National Elecscronics", though I think it might be something like a different gas mixture, I had to use 250v to get multiple segments to light (I was using cathode resistors, so dunno what's up with that) -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

[neonixie-l] Re: An Introduction,
I'm not a fan of multiplexing nixies because of the additional current that can lead to shorter lifespan. Multiplexing was common when components for driving tubes were expensive and tubes were plentiful; today it's the opposite. As long as the tubes dont run 24/7, you will probably get a lot of enjoyment from your display. A lot of us use passive IR (PIR) sensors to activate our displays only when someone is there to look at it. I would use 12mA for 1msec as your starting point, and if it's bright enough, try reducing the current.

[neonixie-l] An Introduction,
Hi, I'm Craig from the north of England. A friend of mine has had a liking for nixies for a while and we've spoke about building clock kits before. However, he bought 12 x Z570m tubes and after a (probably drunken) conversation that I wasn't involved in, it was decided to build a device that displays the distance from Earth of the two Voyager spacecraft and display it on the nixies. So the question was asked, "do you think you could build it?" to which the obvious answer was "I don't know but I'll have a go" A couple of months later we have a working prototype displaying the distances of both craft in miles and km on multiplexed 12x7 segment leds. Next step it to get it working on the nixies, I know from the datasheets (google translated from German) that typical anode current is 2mA and I think that the max multiplexed current is 12mA for no more than 2mS although I've seen elsewhere that it could be 2mA averaged over the duty cycle which would be 24mA My output routine can do all 12 tubes in 1mS but I can insert microsecond delays to slow it to whatever works best. I'm sure that I'll be back with questions soon. Nice to meet you all, Craig -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
