RESONANCE EFFECTS FOR EVERYONE TO SHARE

[scotty1]

Hi all.
I made a small clip to show some of the things i notice with resonance.

I used a square wave around 10khz.
The circuit is just a 555 as you can see, though it has triangle wave as well (not used in clip).

I have just a few ideas I'd like to share with you, but I don't expect you to do it for me.It's just for your consideration.


What is going on if you connect led or diode to the ground wire ? Doe it matter in what direction is it connected ? Does it produce light ? Is it measurable current from ground with ammeter ?  Did you tried with various coils ? What are the results compared to self-induction of coil ? I suspect that a coil with much longer winding should give a much better results, faster charge maybe.

Thank you for wonderful experiments ! Please don't give up !

Hi forest, thanks for looking at this topic and asking these questions.

Here are the answers to your questions.

Q: What is going on if you connect led or diode to the ground wire ? 
A: Placing an LED between (in series) Earth and the connection point on the diode to further raise the cap charge voltage, the LED light to about 1/4 light level no matter the direction but max voltage to cap will drop by about 100 vdc. By placing a diode between mostly stops the cap voltage gain using Earth.

Q: Doe it matter in what direction is it connected ?
A: No it does not matter, it can be connected on positive side or negative side and assists to charge the cap to the same voltage.

Q: Does it produce light ?
A: The circuit will not light a filament bulb but if you use a Gas bulb (neon or fluorescent) it will light it to a good visible level if connected to the DC output diodes (AV plug) but it is a better light when connected before the diodes (AC side) to one wire of the gas bulb and other wire of the bulb is connected to Earth or body.

Q: Is it measurable current from ground with ammeter ?
A: Yes, with amp meter connected between Earth and the DC side of diodes there is 645 micro amps AC when cap is shorted, and climbs to 900 micro amps when charging cap reaches 500vdc and slowly drops as the cap charge voltage raises and once it reaches 800vdc (maximum charge with volt meter attached) it stays at 730 micro amps but if I remove the voltmeter the cap will charge up to 1,200vdc and as it climbs the draw will slowly work its way down to 250 micro amps at maximum voltage.

Q: Did you tried with various coils ?
A : Yes, I have now tried about 5 now and the best score is the result above.

Q: What are the results compared to self-induction of coil ?
A: I took the cap out of the LC and did a frequency sweep from 0hz to 2Mhz square wave and none of the effects can be found that happen at resonance. The maximum voltage charge to the cap at any point was 23vdc

Q: I suspect that a coil with much longer winding should give a much better results, faster charge maybe
A: I am still testing and cannot conclude that at this time.

Stay tuned for updates.

Hi Scotty,

most excellent video demonstration

You are showing many more details of the effects of resonance and I thank you for posting your great video.

Did you use a capacitor in series or parallel in to get the coil to resonate?

Will you try and see how high you can charge a capacitor?

I would recommend a microwave oven cap if you do try it since they can handle the high voltage charge potential available.

Thanks for sharing.

You made a 2nd video in which you replaced the transformer with a single inductor.
but you didn't show us a schematic of the new setup.
Could you please draw us a quick diagram of the new setup?

@wings
The Milan Manchich info is very interesting.  I wonder were he got the roll of insulated FLAT metal from.
I guess it would only need to be insulated on one side so a roll of peel and stick foil would work.

Hi AbbaRue,

Yes okay, here are the details:

It is a series LC circuit like the image below. The inductor is 78 ohm DC resistance, 25mH measured air core and 112mH with the piece of am radio loopstick antenna ferrite core inserted and centered. The capacitor is .6nf and the resonating frequency used is square wave 17.6khz. The capacitor and AV diode plugs are on one side of the inductor which is the ground side of the signal generator and with the Earth ground to the DC side of the diodes just like the first circuit and the generator feed is alone on the other side of the inductor.
