... 3k3 is way low for a direct-driven nixie, I strongly suspect that your clock is multiplexed. Can you tell if all the tube cathodes are wired in parallel? ...
... I wonder if this was ever re-verified... I remember reading about early ICs having similar problems, also initially attributed to cosmic rays, but later...
... <snip> ... Nice tube and nice photos, Peter! This type has been in my file for a long time but I don't think I'd even seen a picture of one before now....
Alan, I can confirm that bit about early IC's... "Alpha particle induced soft errors in dynamic RAM"... read lots of documents/reports and the like way back...
For anyone interested... In the 'Nixies in Film + TV & Other Media' folder, 6 captures from the Australian movie 'The Dish'. Private e-mail to me if you want...
... Sure enough, unpassivated MOSFETs make excellent radiation detectors: Charged particles travelling through the gate oxide cause a transient threshold...
I promised a couple of links for anyone wishing to build their own GPS antenna on a budget. Worth noting most of all is that they are not difficult to make,...
I'll show you nixie testing! http://snipurl.com/3m3n I want to know who took that photo.. I will top that off with my new miniature solid state tesla coil I...
Nevermind, one of the diodes failed and the whole circiut saw ac, so much for that, time to order more samples! microchip.com here I come!@ Jim Mitchell ... ...
This is probably wrong but hey, what the hell! Mux'd nixies someitmes have a problem called 'ghosting' where the capacitance of the cathodes keeps the glow on...
I've been running one of mine for about 12 months now, 24x7, another for about 7 months 24x7, and have not noticed any darkening; I think it's 170V at ~2 ma (I...
No no no, IN-18's aren't hard to find, they are cheaper than ZM1040's which I think have uglier digits, and are smaller then the IN-18. Jim Mitchell ... From:...
Just wondering if anyone is gaining anything from this subject ? If not I'll quit with the posts on this subject, considering it off topic thereafter. If...
... know who took that photo.. I will top that off with my new miniature solid state tesla coil I just built (a week ago), lights up a nixie from a foot away...
It's capacitive coupling, the plasma lamp has a really tiny pathetic flyback transformer, and its just lighting up the nixie. If my SSTC worked, I could get...
Take a Nixie, preferably wire ended, hold either the wires or the bulb, move the end opposite to which you're holding over the OUTSIDE of a TV set. If there's...
Ha! EHT my foot. I got popped by a flyback out of a 30" TV yesterday, just made my hand numb for a while, Note to self, do not hold HV wire when touching...

FYI I have never ruined a nixie. I have plenty of old style flybacks AC output, but they are large and would be big and pose a hazard to the electronics of a...

Thanks Peter for the information. I already knew the reasons for Mux'ing a display, I just didn't know what the construction differences were for a Nixie that...
