InstantArcade@North What are the chances of actually being able to make one of these with the colors?
I remember with the VFD stuff at least, you can get a few different colors using fancy filters in front.
@instantarcade I think it's possible? Some of the colors might be difficult, especially all together. It might require individual grids over each color to get them at the same relative brightness. I don't know enough of the phosphor chemistry.
rrmutt@North @instantarcade Can definitely do most colors with phosphors, like these "aerolux" neon bulbs. I think these are vintage and phosphors have improved a lot!
@rrmutt @instantarcade Yeah, these phosphors are super interesting because, at least as far as I understand, they're not fluorescing from cathodoluminescence (as in a VFD) but from the UV generated by the glow discharge. I think a rainbow flag aerolux would be relatively easy!
@North Yes, wonder if they boost the argon in the Penning mixture to get more UV?
