I was thinking of a PCB with various green neon bulbs (there are other colors as well), and a driver that will get us AC on the bulbs (such as an HV507). On top of the PC board would be a 3D-printed gizmo (black, so it's opaque) that fit over the bulbs to create isolated light patterns for the various segments, and a plastic or glass top-cover. The cover would need to be tinted or colored so you wouldn't see the underlying bulbs.
I'm not sure if you would want to coat the interior of the 3D printed block with a shiny/reflective surface, to maximize emitted light. 3D objects as-printed are not polished, though I've heard you can give them a vapor-bath in acetone to do that. ---------------------------------- I already have a 7x9 neon-bulb matrix display on the drawing-board; obviously that would be much easier to build. But it lacks the artistry of a nixie and E-L display pictured earlier. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
