Mechanical Magic Eye
Split from this thread: https://www.vintage-radio.net/forum/...d.php?t=113812
I know it's not directly related to the thread title, but after doing an internet search for references to magic eye suppressors I came across a novelty item, which I just had to share! http://www.hpfriedrichs.com/radioroo...r-magiceye.htm Carry on.

Re: Mechanical Magic Eye
David,
Many thanks for finding this and posting a link. I don't think I'll be building one this year but maybe when I'm a bit older. Frank C. |

Re: Mechanical Magic Eye
There are loads of similar things available - search online for "USB message fan" - they're surprisingly cheap [some around £5] too.

Re: Mechanical Magic Eye
Hi,
This is really interesting, what an ingenious idea, would this work on all valve radios though if the original magic eye was not obtainable? Paul. |

Re: Mechanical Magic Eye
As long as the voltage available from the AGC line matched the gizmo's control requirements, yes.
I wonder whether a modified meter movement with a suitable thin card disk and some green fluorescent paint illuminated by a UV LED wouldn't be simpler.
