RESONANCE EFFECTS FOR EVERYONE TO SHARE

@everyone,

I just uploaded a new video "test 10"

Hi gotoluc,

Interesting video thanks for sharing.  I think I can explain why you still get power through when you connect the opposite lead of your bi-filer coil. It is because you're getting your coil to act like a capacitor and a coil at the same time. I doubt that too many other folks have come across this in quite the way you have here because of your lamp cord coil, you have a very uniform distance between each wire of the bi-filer creating a nice capacitor in addition to a coil. Before you recoil your coil I think it would be interesting to try some different capacitors with your setup to see if you can find some higher frequency resonance spots. Maybe even no capacitor, using only the capacitance in your coil. It seems like higher frequency gets more output.

When you do decide to recoil the coil, I think you should focus on ways of winding it to maximize the capacitance. That is on thing Tesla was trying to do with his unique windings. It is one key to reducing resistance in the coil. To maximize the capacitance you want the highest voltage wire to be near the lowest voltage wire of the coil, creating the largest difference in voltage though out the coil for neighboring wire. So, considering that the voltage is spread out uniformly from the beginning to the end of the coil, you can imagine some winding possibilities to maximize the voltage difference against all neighbors though out the wind.

Thanks,

Shinz.

@najman100,

Attached is the new PCB layout you asked for. I have made the PCB so that it can be produced
in three different ways. First as a normal double sided plated through holes PCB. This version needs
no soldering of jumpers or through holes. The next version is a double sided not plated through holes
version. This PCB needs soldering through holes in all the jumper connections, but no jumper wires.
The last version is a single sided (under side only) version. This version needs a jumper wire at each
jumper location shown in the design.

(Edit) I forgot to ground one unused port in the IC.
Have done that now, please download this new version.

Groundloop.

@BEP

         I am probably trying to oversimplify but wasnt Tesla saying that there is a current between nodes and antinodes of a wave that is independent of the input current?  These currents then induce voltage which then again terminates at the nodes and a standing wave is produced in the secondary. 

mod.   This standing wave is usually avoided in radio transmission as the oscillator becomes part of it and the voltage rises beyond what the osc can withstand and pop goes the base station.  I would imagine a Tesla coil would max out a swr meter to the point that the needle would snap right off.  This is avoided by the loose inductive coupling to the transformer secondary by the primary.

mod again: (coffee kicking in)   If there is a way to now manipulate this standing wave to expand and contract along the length of the secondary could a vlf wave then be imposed between a top load and Earth?

@Groundloop

Thanks groundloop i will try too make the pcb now the holiday are finished i will try to squeeze some time .

@najman100

Not so fast, please. Just wait until the circuit is given a true green light.

@groundloop

Thanks for the real circuit photo. Now I know exactly what it should look like as I was having trouble figuring which components like caps and resistors to order.

Now you know why I said take a few steps back and re-check. No matter. Guys should keep a cool head and not jump too fast. We should check and re-check this new circuit before any other attempt is made.

Like, on the new circuit, on the 4009N pin 15 is also not used but not indicated in the diagram. I am also happy to see the external jumpers are physically located on the outer perimeter of the circuit board. On the previous board the output terminal was very close to some resistors and a potential for shorting.

Also, I see you are again using the same four npns - MJH11022. I looked at the pdf and there is a model MJH11021 that is a pnp and am wondering if it is not better to use two of each instead, given that the body of the transistor is also the collector. So the heat sinks should not touch each other or they may short.

Just in case, if anyone can make the circuit (when it is ready) and sell it to me, this would save me a whole s*&t load of (time x 10) given my obvious lack of experience in building circuits and I don't mind paying for the parts and the time and whatever else is required. I just sort of fell flat when I started looking to order the parts, mainly the resistors and capacitors. There are so many types that I was just lost. Hmmmmm.

Seriously, there must be enough circuits on the forum that if a guy was really into it, he could review the many circuits and put a price on them for sale. I know some here will buy like me and I am sure there are many that come to the forum just to read and would still like to order some circuits. This would give me more time to work on coils and experiments and not risk blowing a circuit while trying to build it. If anyone or two guys were serious about it and had some spare time, I am sure Stefan would not mind giving you access to a special locked thread with permission to update available circuits and guys could place orders and pay via PayPal. Man that would be a dream come true. Our own dedicated circuit board shop would increase our potential experimentation time and I am sure it would be profitable for the guys doing it.

@armagdn03

Thanks for the link. As usual when they start talking with formulas, I will get lost but there is enough information there for me to understand at least the basics. Thanks.

@gotoluc

Great videos. Thanks. I have been doing some other resonance tests using the @armagdn03 basic but putting the FG first through different coil types, then to the LC circuit and am seeing some very interesting things.
