Interesting read, I'm surprised these tubes are so fast considering my one remaining filament bulb always takes a few seconds to warm up after being switched on. Do these use a different filament type?
- somat 4y agoI think the filament stays on and you switch what cathode is being used. edit, I just read the wikipedia page on nixie tubes, there is no filament, despite looking like one it is not a thermionic vacuum tube. it is a cold cathode gas discharge lamp. so one anode with many switched cathodes.
- ilyt 4y agoNixies don't emit light by heating, it's closer to neon tube
- WorldPeas 4y agoThat clears things up, although I'm curious now why a VFD wouldn't be better
- ilyt 4y agoI think the answer is that they are making Nixie tubes: https://www.daliborfarny.com/project/custom-nixie-tube-for-keysight-technologies/ https://www.daliborfarny.com/project/custom-nixie-tube-for-k... https://www.youtube.com/watch?v=1nHkhJ52iA4 https://www.youtube.com/watch?v=1nHkhJ52iA4 Obvious choice would not be VFDs or nixies but plain LEDs I'd imagine.
