@David: I love the rotation effect in the video, it looks too smooth to be discrete leds - how many LEDs are there?

There were 13 LEDs in this case, because I was using the Adafruit NeoPixel strip with 60 LEDs per meter -- but I'm also going to try the 144 LEDs/Meter strip from Adafruit, which should give me about 30 LEDs around the base of the big tube!!!

Watch this space!!!

@bert22306: Or is it as I expected, that the cathode just isn't boiling off any electrons? Quel dommage!

What a pity indeed -- but we are still at the beginning of the experiments -- someone suggested that the yellow hue to one of the tubes might signify that it would fluoresce if exposed to a UV LED (I didn't even know they made UV LEDs). For tubes with cathodes I expect to make them glow -- someone else suggested that one of the tubes might be some sort of rectifier that could be made to act a bit like a fluorescent tube ... lots to think about here...

LED Effects

I like the effect more with the light bulb than with the tube Max.  Maybe because the tube structures are mostly in the same plane that the LEDs are shining, hence don't get much direct illumination?   I'm also sure that the pics/videos dont do them justice, I know these things are VERY difficult to photograph.

Characteristic curves?

Wait. I thought you had replaced the rather staid and boring heaters with colorful LEDs, and were going to show us some fantastic impact of this on the characteristic curves of antique tubes. No? Or is it as I expected, that the cathode just isn't boiling off any electrons? Quel dommage!
