Here is the schematic, with explanation.
I also build 2 new bulbs and show how to modify the switches.

Thanks man! It was a fun project to dissect and share.

That was Excellent! I really enjoyed that... So wonder if it is possible to raise the bar? I realize the limitation with the AC the maximum number of switches and lights are 2... but I wondered, knowing what we know, if it is possible to do 3 (maybe 4) lamps with 3 (or 4) switches? Obviously the circuit here does not scale; there would need to be a different circuit and solution... I have no idea if it can be done... the problem doesn't have to use the same type of components, same trick with named switches and colored lamps... perhaps using LED's and low voltage DC (or AC) this time... As before, no microprocessor trickery, but I'm sure there will be some electronic shenanigans... but is that possible?

Thank you!! And that is a good thinking exercise. I bet it could be done with some compromises. Possible this coaxial cable to hide multiple current paths. The beauty of this circuit is that even with a multimeter, it mostly appears to be un-gimmicked. the resistance of the filament will hide/alter the existence of the diodes. All the wiring can be traced out completely legitimately. But still, it would be neat to hide some logic gates in and around the circuit to make it seem impossible.

First it was Fermat's Last Theorem and now this. Pretty soon there won't be any mysteries in the world left to solve. What's next...Bigfoot? Loch Ness Monster? Fun channel.

Now that it's revealed it is hilarious to watch the original video. I was looking for "tells". When you show the bulbs right in front of the camera lens it cracks me up! 😆 🤣

Thank you! I've ridden the Loch Ness Monster, ne mystery there... grin. Bigfoot? well.... no comment 😛

@@NelsonClick I know, right! That's the side effect of using painted glass. I think the ceramic frosted bulbs are a lot more forgiving with the heating process.... And here I was afraid the original video was giving away too much! LOL

I really gotta know. Did you draw the lamps and switches on one side of the glass; then draw your "current paths" on the other side of the glass? Inquiring minds want to know! Cool way to demonstrate your circuit! With red and blue lamps, you could really mess with someone who was color-blind! Good job, Eric. I'm never disappointed when you show me something, talk about how it "should work", then build it and amaze us all! TYFBMF!

First off, T(Y)FBMF! And yes. the circuit (everything you see before I fade in) is all drawn on the camera side of the glass. Anything that I wanted to change, like current paths, switch positions, colors were all drawn on the opposite side. It was a fun way to do it since the white board is at Club 809. You'll shake your head when you see how I rigged it all. LOL Oh! and I know you'll appreciate this. The camera was a Logitech Brio with the audio seperately recorded on a Tascam DR-07X with a lapel mic clipped under my beard.

@@intocoasters You know well, my friend. Your video and audio are great! I hope to bring my XA-40 camera down someday and record one of your neat projects, then edit it for you. And we'll use my ECM-50 lapel mic... under your beard! Even though we've been good friends for a few years now, you still never cease to amaze me with your creativity and ingenuity. Be well, my friend.

Nice explanation, although perhaps it would have been easier to follow through the diodes with conventional current flow. My 2 minute guess and scribble had a (redundant) diode in series with each filament.

@intocoasters 2 жыл бұрын

Thank you! I wanted to try to use conventional flow - but it hurt. LOL. Having been taught electron flow for years, it felt wrong to try to draw the current in the direction of the arrows on the diodes. And I can see having a resistor in series with the filament... it would make it behave more like an LED and it would really reduce the current that leaks through the filament. It might make the other opposite bulb a little brighter maybe.

@@intocoasters Ah! I remember why I added the extra diodes in my version. You don't need them in yours due to the high voltage of the supply and lamps. If you scaled yours down to use (say) 3V lamps and a 3V AC supply, the lamps may have enough voltage (0.7V due to the diode) across them to light dimly during their "off cycle".

@@daShare Makes total sense. It would be interesting to see at what current the filament would start to visibly glow. Something I never considered until we all started talking about this in the comments.
