Tesla Experimenters

[JasonD]

I have a personal passion for the work of Nikola Tesla and am looking to chat with others that are trying to replicate his work. In particular, hairpin circuit, pancake coils, wireless transmission, and traditional Tesla coils. I'm new to the forum and don't really know exactly what everyone has devoted themselves to.

I am really interested in discussing experimental observations to give insight explanation to how these devices work. I'd love to say that I built things exactly as Tesla did but I didn't. But, when I made apparatuses incorrectly and observed why they weren't working as expected I discovered some interesting things.

Anyone replicating Tesla transformers and trying to figure them out? Any interesting observations?

Pay attention to Eric Dollard. He is your answer. Study his works and you will get far.

He has done all of the experiments and has developed algebra to describe most everything he has ever witnessed.

The Joulethief SEC exciter and variants thread, by Jonnydavro is an excellent source of inspiration and provides fun, invaluable build ideas by the bucket loads. It's the thread I found when watching YouTube vids one day and followed a link to here. Been here since
From Tesla towers to wireless range tests to plasma speakers to lots more related, it's a cool thread.
If you have a couple of dead PC monitors and the odd other junk circuit or two, you'll be hooked for sure..at zero cost.

watch the youtube movies linked to in the above thread, i'm sure you'll be able to see parallels with Tesla's magnifying transmitter.

JiffyCoil came up with a nice pancake construction technique and I made a thread about bifilar pancake coils a while back.

Bifilar coils are used for some specific purposes, but plain spiral pancakes were actually more often used by Tesla.

Tesla revealed later in his life that the pancake coils shown in the patent were a two dimensional representation of a conical coil:

Hi guys, I like to experiment, but my experiments can look a little rough.
I do learn stuff though. I am currently experimenting with a heavily radiating ( wastefull ) setup now so I can experiment with different ways of collecting and utilizing the radiated energy.

Tesla Exciter/Plate "P" Collector.

The red plate behind the tower coil is an aluminium plate painted with insulation. It is connected to one side of a FWBR on a cap and the other side of the FWBR goes to ground with the return wire from the CFL.

It can charge a 400v 470uf cap to over 40 volts in a couple of minute's.

I can light that same CFL directly from the ignition coil with only 114 Ma but this setup uses about 315Ma to get the same brightness. So I have 200Ma to try to collect back which is a challenge. I'm trying different stuff, I'm driving the HV through the TC primary and into the conical coil spark gap but with no spark. This causes all kinds of fun. If it is connected the wrong way the controll circuit is HV live but it still works, which is amazing the buzz is on the negative, I think that is why it doesn't destroy the circuit.

When I can get the video camera to work propely with the setup running I'll get some footage. the camer will work when the setup is in exciter mode but if I spark the gap the sound go's nut's on the video.


Cheers.

I'm sorry to tangent, but, do you mean it sounds like radio tuner noise on playback ? That's an effect simply of the camera being too close to the experiment. If it's a sharp crack sound then it's the spark doing the same thing, If you get a car battery and short the wires next to a radio you'll hear it...it is indeed odd though how a camera picks it up.
Has happened to a few of us who dabble and record for YouTube vids.

@7imix haha but of course...makes so much more sense of the Russell/Bashar coils and my own experiments when fitting a conical pancake inside a Tesla tower as the primary! Thoroughly recommended.
