llewelly@North this is the future Alan Turing fought for
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.
@North I remember the early 90s HiFi components with a single display but a filter over the top cut into segments, and being able to do white, blue, orange, and red at least.
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?
PaulNickson 🕊️🎛️🎼@North @instantarcade All it is is colour bars but in landscape ..?
@PaulNickson @instantarcade Right. You mean like on CRTs? Those do operate on phosphorescence, for sure, but they have two advantages: 1)They only need 3 colors and 2)They have access to different phosphor chemistries because they work at very high potentials and, by extension,. higher activation energies.
@North @instantarcade Agreed but it was (is?) the PAL standard test card to check phase.
@PaulNickson @instantarcade Yeah, for sure. I just don't understand what it has to do with Vacuum Fluorescent Displays
@North @instantarcade Sorry. Now I get it; you’re referring to vacuum tubes specifically. D’oh!
@PaulNickson @instantarcade Hah, it's all good, no worries!
@North @PaulNickson Okay, now I'm thinking about gay micro CRTs :)
Shae Erisson@North Is this a real thing I can buy? I want to put this on my desk!
@shapr I wish it was! Maybe I'll be able to build them one day?
@North Closest thing I've seen is the RGB IGG-64 tubes like https://hackaday.io/project/46302-1-64x64m-adventure but they're a pain to drive at 360 volts.
(they come in monochrome orange, two color, and three color)

These display panels were lying around for quite some time now, waiting for an hypothetical interest. I decided to gave them a bit more focus after the interest shown on the dittohead's page : https://hackaday.io/page/3002-giant-nixie-panel-from-ussr [https://hackaday.io/page/3002-giant-nixie-panel-from-ussr] The challenge here is in several parts. - Finding documentations and translate them. - Driving the elements with >360 volts. - Find a solution to drive the 128 inputs from few microcontroller GPIO - Ultimately make it controllable with I2C/SPI/serial
Sander van Kasteel@North shut up and take my money!!!
(And please, give me a datasheet 👉👈🥺)
Martin Frost@North ok, but how do I get this into a guitar amp?
🏳️⚧️NotPike🍀@North nice :3

@North 🌎🧑🚀🔫🧑🚀 Always were
Simon ZerafaWere they pulled from an HS2 Gaydar set perhaps? 😉🤷♂️

They've always been gay, especially back in the 50's and 60's. They were afraid to come out until now.
