Updated Master Legend

Post by rodrigo » Tue Feb 26, 2019 3:44 am

This document is several years old, and some of the symbols are known these days (thanks to some final touches from @mlogger), so I've updated the document.

I had originally posted it to the Yahoo group, but that seems dead these days, so I'll post it here.

If there are even newer symbols and/or more info, let me know and I can edit the doc with it.

I saw this over on the C-L facebook group, and now here too! Easier to find here!

Thanks for this super resource! I was reading through the paper circuits osmond files and ???? at some of the symbols.

This is brilliant, thanks for doing this.

I've been looking into the symbols myself and I agree with all but one of the symbols. I might be wrong of course! :)

I think the circle with a smaller circle and three terminals could be a 4.5 to 65pF variable capacitor (trimming capacitor). I've seen a picture of the deerhorns assembled in a workshop in Berlin (I can't find the picture now, of course!) and that is what it looks like to me.

I'm prepared to be wrong and I don't have Facebook so this might have been thrashed out already over there.

Edit: here's the picture:

I've looked in the Osmond PCB file for the Deerhorn Berlin, and that part is called "rrrcaptrim", so I think I am right and it is a variable / trimming capacitor. :)

I'll probably have a go at making the Deerhorn Berlin paper circuit (but on perfboard) when I've completed a couple of other projects.
