Here's an interesting video, exploring the possibility of a substitute for EM34 style tuning indicator valves.

Interesting idea but I think I prefer the all electronic version (rather like the EMI system over Baird)!

That's really clever but I would have thought it would be simpler to have a series of segment type LEDs arranged in a circle, covered by some kind of diffuser. Totally electronic, like EMI!

interesting idea, looks rather complicated to me though! When it said about electro-mechanical magic eye tubes I thought maybe it would have something like a little meter movement with a pointer made to cast a shadow in front of an led, something I might try myself! I’ve got an R1155 radio here that could do with a new magic eye, maybe time for some experimentation, when I’ve cleared a few other projects out of the way.
