Reviewing Pulse Motor Circuit Ideas and Theory

[darediamond]

Hello Everyone,

I'm quoting myself here from the beginning of this thread and would like to pick up here.

After going back through my notes.
1. How would Tesla ever have achieved the frequencies (megahertz to nanohertz ranges) he mentioned with the equipment in the late 1800's to early 1900's. Amazing. More importantly, there are frequency generators on the market in the tens of thousands of dollars and upwards USD, that can actually generate these signals in the extremely high frequency range in  which Tesla mentioned.

2. At least on one of the points I had written down in dealing with Tesla says in paraphrase,  So actually getting or making a frequency generator of this type may be difficult or expensive, and maybe not even completely necessary, considering that my initial query dealt with being able to trigger a coil without a rotating mechanism.
And this last point,
3. Many low cost frequency generators abound on Ebay, and TinselKoala was considerate enough to provide several circuits and his Youtube videos, including the discussion we had concerning PLL and Tesla coils. I believe the 555 timers can get frequencies over 1 MHz with the right capacitors and resistors. My question in this area actually deals with creating a high frequency (megahertz range) coil and what parameters are involved to create that device. Specifically does it have to do with wire size,length, wire wraps, length of coil, and diameter? And if any of this is true, what algorithm can be used to consistently do this?

Thanks for everyone's involvement,

Yes High frequency matters in harvesting Radiant Energy. But his well WOUND YOUR HARVESTER ACTUALLY DETERMINES THE AMOUNT OF ELLECTRONS YOU WILL BE A ABLE TONHARVEST AT ANYBLEVEL OF FREQUENCY.

**1Mhz switch will do you no good if your coil CAPACITANCE IS LOW**

To Maximize the harvesting of Air-Electicity at any frequency level, YOU MUST UTILISE SERIALLYNCONNECTED MULTIFILLAR WIRE to make your coil. Use Thin gauge like AWG#40 or if that is too thin to handle, use AWG#31 to make your litz wire.

When winding, separate each layer with Plastic tape over and over to make the coil an High Capacitance coil.

The best way to wind your coil is in SPIRAL FORM as this allows for EXTREMELY HIGH CAPACITANCES BECAUSE YOUR WINDING BE IT CLOCKWISE OR COUNTERCLOCKWISE WILL BE IN ONE DIRECTION THROUGTH. NO zig zag as it is in Helical winding which necessitate winding from left to rigth. Rigth to left.

The high capacitance of your coil will generate Concentrated Magnetic Field and as this field is being rapidly switched over your Lensless Partnered Output Coils, You will be able to harvest high amount of Electrons.

earthbound,

If you are really interested in electronics then you need to get a copy of the ARRL Radio Handbook.  It is the book amateur radio operators study when they want to move up to a higher level of license.  They also study it when they just want to learn how electronic things work.  It has all kinds of formulas and examples of electronic circuits.  You can find them on Ebay for about $25 in good condition.  I have seen some that look slightly worn for as low as $10.  You don't need to get the latest version.  Even editions from the 1960s will have all the formulas and tables you will need.  The later versions will of course have more information on solid state devices instead of vacuum tube technology.  An edition from the late 1990s will have most common solid state devices in it like the 555 timer and mosfets.

Carroll,

TY-just bought the 2016 softcover from Ebay.
Will begin the trip when it arrives. I appreciate the direction. You may have mentioned this before too. Some things are worth repeating though.

so darediamond,

Mentioning the spiral multifilar series wound coil, are you talking a about the Tesla type pancake coil design?
It would seem that getting enough wire in a coil of that type would be difficult as the diameter of the coil would be huge and impractical, but if kept to around 2-3' in diameter,
then maybe that could be done, especially as a multifilar type. Making the multifilar winds would be a bitch though, as I'm seeing literally 100's to maybe over a thousand feet
per each filar portion and using a 30 gg magnet wire. I have 3 miles of this wire, but the measuring would be very inconvenient and then making the multifilar portion, too, after that, if made in a twisted fashion like the Bedini wound coil.
I remember making my 8 filar Bedini coil at only 125' long each strand. Still no fun. The pain would be compounded here. Based on the diameter of the 30 gg wire, an 8 filar arrangement would be about 1/16 - 3/32" in diameter.
And this coil being flat would be even more difficult to wind I imagine. Using the formula for circumference yields C=2πr

Anyway, any suggestions for making this? Always good to have others' insights, especially those who have actually wound a coil of this type. The other thing is, how does one keep the
multifilar circular strands laying flat and immobile as they are being wound? Also, should one start at the center and wind outwards, or vice-versa?
I was thinking that a motorized lazy-susan type wheel could be useful in this arrangement.

Thanks,

Good Morning All,

I have been studying 555 timer circuits, the 4046 PLL chips and circuits, op-amp chips and circuits, and watching lots of Youtube vids, etc., trying to get a handle on the use of this data for my Project related to high frequency pulsing of an air coil, or one that has a core that can withstand high frequency pulses such as carbonyl iron and ferrite ceramics. I also breadboarded and tested some of these circuits.

Anyway, this website:
http://www.electronicecircuits.com/electronic-circuits/555-variable-frequency-square-wave-generator
shows a simple 555 timer circuit with the opportunity to have some variability of frequency in a square wave output (and I don't know if a square wave would be appropriate in the circuit mentioned below for cap discharging, maybe saw-tooth is better). The variability is based on either changing the C1 capacitor to suit one's goals and/or a combination with a variable resistor in series. The Timing pulse outputs through Pin 3 with almost equal voltage as the input voltage on Pin 8 per the data specs. From what I have read concerning Tesla theory extremely fast discharge times are very important (at least in his spark gap machines).

Another area of interest along these lines relates to the capacitor discharge in a Bedini-type circuit going to the Charging battery. I have looked at some sophisticated Comparator circuits, including the MH op-amp circuit, which automatically do the discharge at preset times, but I also looked at the 555 timer circuit above for something to get started with since it outputs a known voltage at intervals as well. By using the output from Pin 3 and sending it to a solid state relay, the cap can be directly discharged into the Charge battery at intervals thus fulfilling one goal, that being the automaticity of discharging the cap at periodic intervals. If you all, who are more experienced in practicality and theory, read this and disagree, please enlighten the ignorant. There is no sense reinventing the wheel. I did read through the part in the Bedini Advanced book and didn't actually see a true clear circuit for this.

This video is from Chris Barber on Youtube and shows a comparator circuit as well using an SSR for the discharge path and an LM741 chip as the op amp.

Because I'm not very experienced in reading the flow very well and the exact logic extended in the video, I need help. On the left hand side of his circuit, after the the bridge rectifier portion there is a high value cap, 15K uF at 75 volts, which I suspect is the collecting cap off the mains coils. I can't tell here how the comparator is working. Is is actually measuring the charge coming off that cap and comparing it to some other value to make its determination of when to switch? Or is something else going on? The reason I ask that specifically is because in the comment section of the video posting, another member mentioned that by changing the cap value of the circuit coming into Pin 2 to a larger value from 2.2uF, Mr. Barber would be able to discharge his cap down more, as that was a problem he said he was having. Not being able to maximize the energy removal from his cap.

Either way, would the simpler 555 timer be just as good for early experimentation, or should I just go ahead and build the LM741 comparator circuit? I have almost all the parts for that.

Also too, why dump the cap from the Neg side and not the positive side as seen in Mr. Barber's circuit? Any particular value in that?

Thank you everyone for all your insights and directions.
