Coil Resonance Tutorial 4

[IsItTrue99]

Could you have just used the second wire on the speaker wire coil as the secondary (pickup coil)?

Cheers and thanks for posting this series

@IsItTrue99

Yes you could but it may not be the most efficient way to extract the energy. One would be best to experiment to find the ideal tuned receiver.

hi there..this video was amazing. i am working on a wireless power transfer project..just several question though.  if i am using a normal copper wire instead of using the audio cable would it work?another question is what type of capacitor that you used in this test??can u give in detail of the capacitor that you used...it would really be helpfull

[gotoluc]

@healtybiotic

It will work with normal wire also. Capacitor used are non polarized since the input is AC. It was a ceramic capacitor in the Pico Farad range.

All the best in your experiments.

after fiddling about with this setup I realised i ddnt have a large enough inductor to light a neon ,, i could get it to strike sometimes but that was only by flicking through the ranges on the frequency generator ... I also realised a good easy way to fine tune it though ,, I just put a multimeter across the neon to find peak voltage :) I was only getting up to 58 volts with my coil ..

You are a star ,, this series of videos is the best explained I've seen ,, I've got lots of electronics stuff but i struggle with theorys ,, this helped clear it up loads .. 5/5 !

Hi ZED74,

glad it can help. Thanks for posting your appreciation.

The only thing I see here is you showing how resonance bypasses certain parts of the cicuit. The bulb is not an effective way to show anything but the action of resonance bypassing it. In order for you to show anything real you need to measure the input from the source and the output from the endpoint. Everything in between is acually becomming a perfect conductor and not showing anything being used. The energy is still comming from the source signal gen but only showing at the end.

wow man you mean the energy is from atmosphere? i have heard of people putting devices under power lines and tapping huge amounts from them. just cause the coil is receiving a tiny input it actually amplifies the input at resonance? is this radiant energy? i have never seen an active example of overunity. thanks

Hi tubemp777,

as I replied to MRH2O2 above this video is not to make a claim of over unity. It is only to teach others how to use simple instuments and observe the effect of resonance. In time I will be doing real maesurments. Not ready to do this yet since the effect could be improved. I think MRH2O2 calcalations below would be closer to the energy output. You are correct though as to why I use a bulb instead of an ammeter at these frequencies.

Excellent work! This knowledge can be usefull in replicate Stanley Meyers water fuel cell

Hi Luc,

just try to use the whole

Loudspeaker coil with the 2nd paralel wire.

Just wire this as your pickup coil, so it is

a bifilar pickup coil

or use the real Tesla flat coil principle

(wiring inverted bifilar for not canceling but enhancing the magnetic field of the coil)

to get more stray capacitance for the loudspeaker coil.

Many thanks.

Regards, Stefan.

Hi Stefan,

thanks for looking. Your idea sounds interesting and was wondering if you could take the time to post an illustration of this at the topic this would help me understand it better. Thanks for your suggestion.

@tubemp777 - 8W??

0.283v/10=2.83E-2^2*10=8.0mW milliwatt

0.570v/10=5.70E-2^2*10=32.49mW

0.828v/10=8.28E-2^2*10=68.56mW

0.865v/10=8.65E-2^2*10=74.82mW

This is even off because I doubt the capacitor and the single phase diode is even close to a clean DC, therefor all powers would need reduction.

Could you indulge an old fart for a moment? Because you are for the most part using a step down transformer, could you please install a 1ohm resistor in series with the circuit to sig gen ground and measure with your scope across the 1 ohm. I so much want to be objective here, yet my calculations so far indicate that that bulb is useless as an indicator of input energy??

Thanks and keep up the work.

Hi MRH2O2,

this video is not to make a claim of over unity. It is only to teach others how to use simple instuments and observe the effect of resonance. In time I will be doing the maesurments as you suggest. Thank you for posting.

Was the variable cap in parallel or series the other cap when you added it?

[gotoluc]

Hi bartley440,

if you add capacitance to the existing capacitor you would add it in parallel.
