HI Team

I arrived at this forum with the goal of learning how to make a Eternal Flashlight, but found a wealth of knowledge far beyond expectation. After much reading, watching, coils and experimenting quietly, its is now time to see if I can offer something to this effort. 

I decided to start with a "Lariman" build due to its circuit simplicity but still with the necessary components to understand the coils and what is required to tune them to the circuit. I have ordered circuit boards based on the above design and have a number of spare which I am happy to post to any one willing to commit to building and posting their progress.

Lariman Circuit Boards

So I will build one up and wind some coils and post progress soon.

Ok - so I built up the circuit based on the standard design, but took some liberty with the coil winding based on what I have come to understand. Please tell me if I am on the right track re the coil design. The circuit shows a 28 turn primary and 66 turn secondary. However it seems that there needs to be a bucking arrangement in the secondary. 

I used a C core and wound the primary with 31 turns (CW 2.1 meter / 3.67 mH). My understanding is that this should be about 1/4 the total length of the Bucking Coils (L2 and L3) which worked out to be 90 turns CW (27.2mH) and 63 turns CCW (12.94 mH)  or L3 = 0.707 x L2  as we have seen demonstrated in the Mr Preva experiment as well as other devices. 

First question is am I over complicating this coil design or am I on the right track?

If so next I need to work on resonance for the primary. But as it is I note some interesting effects.

With the coils together when I power the circuit with 9V I get very little light on the LEDs. But if I slightly separate the C Cores and reconnect the circuit springs to life and the halves of the C Cores attract each other. Current consumption is about 150mA and the IC gets hot. Playing with the separation drops the current drawn and the LED intensity. If I rotate the primary C Core so it is essentially CCW instead of CW the attraction of the cores is less, consumption drops and the LED brightness drops. There is a fair degree of instability noted also. 

It has been noted the L2 should be assisting L1(the primary) I am not sure from what I have found so far if the relationship should be L1 CW L2 CW L3 CCW or L1 CW L2 CCW L3 CW (where L3 is 0.707 x L2)

Next I will try tuning the primary to see if I can find resonance and lower the current draw.

Hi Brian,

I hope you dont mind, I moved your excellent work to its own Thread, its too valuable to be lost in a discussion thread!

I see your circuit is quite different from what I had poosted here.

I sometimes get the feeling the Circuits are not right. I also replicated the same sort of Circuit: Chris's Replication of Lari Man's Объект 013Б

I was not successfull in this replication even though I felt it would work...

I will post more soon.

Best Wishes and Thank You for Sharing!

Brian posted this 17 October 2021

Thanks Chris

Are you able to confirm if the secondary coil should be a partnered coil arrangement? I note that the exact working configuration does take some tuning. I don't understand how excess energy could be created without such a bucking arrangement.

Also of interest is how the 2 C Cores attract each other when the circuit comes to life. Is this confirmation that the secondary is assisting the primary? or is it normal for a transformer wound on C Cores?

Regards

Brian

Hi Brian and all Readers;

Please read my Pages: Builders Guide to Aboveunity Machines

All the answers you seek are in those pages! If you dont read the pages, youre wasting your time.

Thanks Chris

I have read that thread, but it seems I have missed a concept. I will re read.

On a positive note, I have the current draw down to 11mA with good brightness on the LEDs

I have tried several core types, C-Core, Pot Core and Toroid. To date the toroid is performing the best. All have a primary coil of around 7mH, with the secondary wound as a partnered coil with a 0.707 relationship between the 2 coil windings on the secondary.

 

Brian posted this 18 October 2021

A quick update.

I revisited various coils with the focus to get resonance on the primary. I managed to fry 4 x 34063 ICs in the process. Good thing they are cheap and I ordered 20 at the time as I had in the back of my mind this might happen on that circuit.

Need to give a bit more thought for the coils. laughing

 

Brian posted this 18 October 2021

Ahhh - it seems I might have been over thinking it. As Chris noted in the thread attached some time 2 coils can do the job of 3

Time to wind some more coils

experiments / partnered-output-coils

Twenty years later, we are a lot more advanced and know that we must Break Symmetry, and move to Asymmetry. In other words, the use of Three Actions:

  1. An Input Pulse.
  2. An Output Induction Phase.
  3. A Secondary Induction Phase.

 

Three Phases all up, making an Asymmetrical System!

We can make this happen with Two Coils, or Three Coils, each Coil having its own phase, or one Input Coil becoming an Output Coil also, making up the three Phases.

Using two Coils and three Phases is what Aukla commonly used in his lantern's:, we covered this in Self Powering Above Unity Machines

 

When the Mosfet is On:

 

When the Mosfet is Off:

 

Don't forget, Amplifying or magnifying both Voltage and Current is easy, we have covered this many times! We only need combine the two methods, and find Magnetic Resonance, and this bursts into life!

Brian posted this 21 October 2021

Hey Team,

Well I can report that I have found at least 2 dozen ways NOT to wind a coil to make this circuit worklaughing

I have tried the following configurations

Primary 28 Turns CW, BC1 42 Turns CW, BC2 28 Turns CCW on Toroid, C Core, E Core and Pot Core

Primary 28 Turns CW, Secondary 66 Turns CCW on Toroid, C Core, E Core and Pot Core

I have also reversed the legs on all combinations to see the effect and tuned with a variable air cap 430pF

I also wound the primary with more and less turns and doubled the turns on the secondary on some to get the voltage up.

My greatest success was with the Toroid and the E Core both wound Primary 28 Turns CW, BC1 42 Turns CW, BC2 28 Turns CCW. Seems this winding in general performed better. The current draw on both were 11mA.

I ask your thought on which wave form is the better of these

Or

The first is E Core with 14Vp-p and the second is Toroid with 20Vp-p

Hi Brian,

I believe the waveform was shown, should it not follow this shape:

 

At least for this circuit? Oh, yes, I see there are a few Circuit Variants, I saw this one:

 

and this one, which I used:

@Brian, is yours different again? Can you post please, so we have an idea on your direction.

@Other Readers, please correct me if I am wrong or have my Wires Crossed, bad acronym sorry!

Brian posted this 21 October 2021

Thanks Chris

This is the circuit wizard file I built which is similar to the second. But looking at the 2 above the seem to be the same just different layouts. I must be missing seeing some point of difference.

I did have some tests similar to above waveform around the 280Khz but they failed to produce enough voltage to light the LEDs.

Thanks I will go back and revisit them.

One further question - for D1 I am using a 1N4004 - do you think it is suitable or would you suggest something different?

 

Chris posted this 21 October 2021

Hey Brian,

Yes, that is the same circuit I posted here, its the same Circuit as the original Объект 013Б, I posted a copy of the original files here.

I posted my failure on this circuit here. I was not able to make the Circuit, that I replicated, work as was shown!

I believe the basic layout works, I believe the machine did run as was shown, but believe the Circuit to be fake. Not real or not accurate!

In the future, I will show this circuit running by itself.

This basic circuit is based on Andrey Melnichenko's GLED.

What would I do to the current circuit to make this work?

This:

 

Of course, Q1's tunning would be critical!

Hello Chris and Brian
I think the key to this circuit is to make it work in  selfrunning mode and with an asynmetric transformer.
I will post here this circuit here with an oscillator which adjusts his frequency to the coils and to the spread capacitance of the coils.
I am building such a coil with E core. Oscillator is ready and functionnal.
Jagau

Chris posted this 22 October 2021

Hey Jagau,

Yes, I agree! Magnetic Resonance is key, and the Input must be just enough to bring the Interactions of the coils into Magnetic Resonance. At peak Voltage is where we will have Magnetic Resonance.

A great deal of tuning is required for these Circuits, and if one has good SMPS knowledge, then I think that would make this all the much easier for a full circuit design, I posted a thread Here on this very topic.

I wish I did a University Degree on SMPS's and then maybe I would not have so much trouble making these small circuits work!

The Coils are the easy part!

Using various methods they are easy to make do what's required!

Best Wishes,

   Chris

Brian posted this 22 October 2021

Hey Thanks Jagau and Chris

This was a really circuit was a really good exercise. Even though I was way off track I did learn a good lesson in tuning the different coils. One turn can be the difference between the circuit coming to life and DOA. It has bought home that the solution could be that next thing or next thought or maybe adding that other value cap. Persistence seems to be key. The more I persistence the better I get the feel and knowledge and better decisions are made.

I am going to put this to one side for a little and move on where I was heading with this which was Andrey Melnichenko's GLED

I have spare boards so if there are members that would like to commit to the build I am happy to send.

This circuit design is from chris-s-replication-of-andrey-melnichenkos-gled post

Thanks Chris

Jagau posted this 22 October 2021

So I redid the proposed circuit with my autonomous oscillator at very low consumption and the circuit operates at about 620Khz as the author suggests and substantially the same waveforms, but as in Akula's circuits the problem of recharging of the primary capacitor does not occur with this type of circuit.

Jagau

Brian posted this 23 October 2021

Thanks Jagau that is good information.

Are you using the 28Turn / 66Turn coil winding design or  do you have the secondary with partnered coils of 42Turn and 28Turn as it appears to be when he unwinds his coil?

Kind regards

Brian

Jagau posted this 23 October 2021

Hi Brian

I used 28T / 66T

the 66 is a POC of 33 CW and 33 CCW

Team 

In regards to the GLED Build what is the recommendation for the FET and Diode?

It looks like Chris used a KT805 in one design yet I see 2N3055A stenciled on the board. I was thinking of using a IRF3205. 

For the diode will a 1N5817 be ok? I see a lot of these circuits make use of Schottky diodes or should I just stay with a fast diode like a UF4007?

Thanks Again for your help.

Brian

 

Brian posted this 23 October 2021

Just looking at the coil winding now - from reviewing the videos it looks to me that L1 is about 26 arm lengths on the unwind, so lets say 26 meters and L2 is 23 meters with the inner and outer copper strip connected either side of the L1 winding.

I would think this will not produce the impendence recorded on the schematics.

Any thoughts? Else I think I will start with what is observed rather than written.

Regards

Brian

Vidura posted this 23 October 2021

Hi Brian, the kt805 and 2n3055 are bipolar transistor, not MOSFETs. There is a substantial difference in switching characteristics and a certain feedback from the coils seems to be easier to achieve with bipolar transistors ( double pulse). Schottky diodes are superior for higher frequencies in general. Vidura

Chris posted this 23 October 2021

Hmmm, Brian, I see your PCB's are missing the names on My PCB Design:

 

 

I wonder whats going on here?

Brian posted this 24 October 2021

Hey Chris - I used your supplied files unedited - it seems only the white font came out on the screen print.

I also just noticed yesterday the circuit diagram is wrong (around the LEDs) but the circuit boards seems to come out correctly.

I am new to circuit wizard and the gerber files. It took me a couple of goes to get the naming correct with JLC, but I don't think that has caused the missing text.

It is not my intention to remove credit as I respect the enormous effort you have made and still do make with this site and your work.

I do apologize for this error. And will correct the writing (change to white) and reorder with next order I place on JLC as it will be only $4 to get a new batch with this correction which I will send to any members interested.

Kind Regards

Thanks Vidura

The circuit shows a MOSFET but it is very good to know the better performance with the use of a bipolar transistor.

I will run with the Schottky diode also.

Hi Team

I have finished the circuit and wound the Pot core with copper strip.

I did a short test wind and assembled and measured to get a rough idea of the lengths required. From this i noted a couple of points.

Watching the coil unwinding video it shoes he did about 26 arm lengths on the primary and 23 arm lengths on the secondary, which is a long way away from the 22mH and 57Mh shown on the schematic. So I decided to go the path as shown in the Chris's replication of Andrey Melnichenko's GLED group.

My first completed winding with copper strips across the primary resulted in 34.7mH Primary / 72.8mH Secondary resulting in a 88Hz  waveform on the gate tunable to about 167Hz. Calculations show that if I lower the Inductance of the secondary this frequency should drop which is not the 269Hz shown in the successful replication. 

You will note also that I have no resonance waveforms on the primary. I used a 560nF timing cap here instead of a 510nF as that was all I could get my hands on. This will result in a lower frequency I believe so I will need to change that.

Next steps

  • Change the timing cap
  • Take off some windings to get closer to the design

Questions

  • Is it confirmed that 22mH/54mH is the working design?
  • Do we have to tune the capacitance also by trimming the copper strip?
  • Will it work with a IRF3205 or do i need to wait for the KT805 to turn up?

Kind Regards

Hi Brian,

This video is a start to further understanding:

 

Best Wishes,

   Chris

Brian posted this 28 October 2021

Thanks Chris

What I am not understanding is that it is clear that he has the 2 copper strips across the primary. He unwinds 23 arm lengths of the secondary and then 26 arm lengths of the primary (which would not create the inductance ratios he shows on the schematic). Additionally there is another layer of tape he does not take off and at the very end of the video when he puts the unwound coil down (which has the inner copper still on it) there appears to be another layer of tape and a further inner winding.

This inner winding could be the partnered coil of the secondary (but I don't see where he disconnects this)

The length of wire he has would also result in far more turns required to the recorded 26 or 54 mH

Am I on the right track??

Hi Brian,

Electrical Energy must be Generated. That is, Voltage is Sepperated from the Copper Atom, and the flow of Current Supported, This is opposing Magnetic Fields. Bucking Magnetic Fields.

Faradays Law, if used Symmetrically, will always be Below Unity! If used Asymmetrically, then Above Unity results can be achieved.

The Circuits we have been given by other researchers are often confusing and hard to replicate! We know this already!

Thanks Chris

I hear what you are teaching regarding Asymmetry in bucking magnetic fields, and the need to achieve resonance for efficiencies in the machine. What is confusing is this understanding, yet watching the video of unwinding the coil appears to show 23 arms length on the 54mH coil and 26 arms length on the 22mH (which is later labeled 26mH).

Are you able to clarify how this meets need for asymmetry (as it does work), but windings appear very close to symmetrical.

I do apologize, I feel I am missing something very basic here.

I will wind a couple of different versions, focus on finding resonance and see what reveals itself.

Hi Brian,

Electromagnetic Induction as it stands in Science today is entirely Symmetrical!

 

Conventional Transformer

Primary Turns M.M.F is Equal and opposite to the Secondary M.M.F. This means Ampere Turns are equal and opposite, we see Symmetry as each Force Cancels itsself:1 + -1 = 0.

 

Conventional Generator

Shaft Torque is proportional to the Magnetic Field Reluctance on the Shaft due to the Stator Coils. Again M.M.F is the force and Ampere Turns are equal and opposite, we see Symmetry as each Force Cancels itsself:1 + -1 = 0.

Shaft Torque: τ

τ = r F sin θ

Where:

  • τ = torque
  • r = radius
  • F = force
  • θ = angle between F and the lever arm

 

If the best Generator in the world is 95% efficient, then Shaft torque, Windage Loss and other losses make 100% then we get 95% Electrical Energy, a Symmetrical System can never go above unity!

 

Asymmetry or Broken Symmetry

Symmetry of M.M.F + -M.M.F = 0, Asymmetry of M.M.F + -M.M.F + M.M.F = 1, we now see an open door, where all of Science has lapsed entirely this other half of Natural Science of Electromagnetism. 

Applying this to the Conventional Transformer is simply using all of the -M.M.F and canceling this entirely so it does not create a negative effect on the Input... Sounds simple, it is once one understands this!

Andrey Melnichenko gave us this analogy:

 

It is easy to confuse simple things! It is easy to over complicate this! Its important one thinks simple about this and applies the right steps, if one can use this following analogy:

and then apply the Balance and Imbalance of Force, then this becomes very easy very quickly!

The Secondary of any Conventional Transformer has an M.M.F that is entirely Wasted and always has been!

Using smart Switching techniques and different Inductances we can achieve the same Asymmetry, or M.M.F Imbalance!

Best Wishes,

   Chris

Hi Brian
Don't worry, researching isn't easy. We are all there. When you watch the inventors' videos, everything looks easy, but these inventors have found something that they will not say in all the details. It is up to us to do the rest.


What Chris teaches is a proven and working method.
The parthened output coil, P.O.C,, are part of the secret which seems to be common to several inventors.
The way in which they are used will be your little secret to discover.

Good research.

Jagau Thank You My Friend!

All here should know, I still have a bit of trouble making a machine work! I can not Predict a Machine, there is some guess work! I have to feel my way forward. This is why I cant say do X, Y and Z and you will have a working machine!

We have a: Working and Proven Technology, yes we do! Many here have achieved the Goal! I am sure all that have achieved this goal will also admit that there was some work to getting a machine to work properly!

I can guide all wanting to learn to the end goal, but can not do it for the inquisitive experimenter! All answers I have, are in the pages here on this forum! Many have succeeded as a result of this easy path I have laid out for others!

CaptainLoz is one of many:

 

Tinman used the very same concepts:

 

Others here also have achieved great success! To achieve success, one must follow the path with passion and dedication! Stick to the basics as directed! Do not deviate!

Remember: Many roads lead to Rome!

The same outcome can be reached by many methods or ideas. This phrase refers to the road system of the Roman Empire, in which Rome was positioned in the center, with every road attached to it. All roads lead to Rome, so you can approach the puzzle any way you like, as long as you solve it.

 

Once one has done this once, it becomes very easy, but still some work is required, its not a 5 minute job to get a machine working.

Starting with an open mind and the will to learn is half the battle! Here, at aboveunity.com you have a support team that will guide you the best we can! Else where, this does not exist!

Thankyou Jagau for your encouragement and Chris for you information motivation from other successes.

My thinking there should be a POC coil on the secondary for this to work, but the video of the coil unwinding does not agree and shows what appears to be a symmetrical coil of about 23 arms length each (it is 26 and 23 or if I approximate it in meters it could be around 20 meters each - but again no way to verify other than a estimate of how long each pull is) This symmetrical arrangement does not agree with the schematic or Chris's proven teachings. The other point causing me some concerns is that it appears to me no apparent capacitor is in a resonant circuit with either of the coils. The 510nF is a timing cap for the MC34063 and the 100uF could have a effect between the two coils, but I am unsure how to calculate this. So is the resonance achieved by the capacitance strip and internal capacitance of the coils.

Another point of note in all of my configurations Q1 does not seem to have any effect if I remove it from the socket, even though it is switching.

For the record which may be of use to others these are the configurations and thoughts I have progressed.

My base here is to accept the core unwinding video as accurate and attempt the replication. All are wound on a 45mm pot core. Yellow trace is on CN1. Blue trace is on CN3.

Test 1 - 20m / 20m with copper strips connected either side of the primary.

On a positive here the frequency is in the ball park and CN3 waveform looks like video, but the voltage need to be increased.

 

 

Test 2. 20m / 28.26m (20 /.707) with copper strips connected either side of the primary.

To increase the voltage

Voltage up a little, frequency still ok, but still no resonance.

 

 

Test 3. 14.14m/28.28m (in attempt to increase voltage further, had to reduce primary as could not fit any more wire on core) with copper strips connected either side of the primary.

Not much of a change here - expected more voltage

 

 

Test 4. 7.07m/28.28m ( a further attempt to increase voltage while trialing to see what effect 1/4 length produce) with copper strips connected either side of the primary.

This is probably the least successful as all other tests were run with 4 volts as the supply, needed to increase to 6 volts. A very slow waveform of 22.4Hz - not the direction required.

At this stage not really sure what to try next??

I feel I am a long way from where I need to be. I will continue with this project as others have succeeded with this circuit, so there is a way.

Kind regards

Brian

Hello everyone.

First of all apologize for not being active
for a long time, work issues because
these are difficult times.

Chris the capacitor value is wrong, it is not 510nF is 510pF
since it determines the maximum time for Ton.
Ton=(C/0.00004).
The MC34063 is a hysterical DC/DC converter,
this means that you can vary the two times Ton/Toff and by
consequently their frequency of work.
The maximum duty it is capable of generating is approximately
85%, ton duration is controlled by the control loop and current
that senses between the pins 6/7 through the series resistor.
This current is determined by the voltage drop between these terminals and
is about 0.33V.

That is why their waveforms have nothing to do with the replications made.
Brian, it is the capacitor of 100uF that when it is at its maximum negative if
it is placed in parallel to the input capacitor this recharges it.
It is more complex than what I expose here, but it is a good approximation.

Thank you.

YoElMiCrO.

Big thankyou YoElMiCrO for finding my mistake. I note alternate circuits use a 330pF cap for timing the MC34063.

I have replaced with what I have available atm which is a 560pF. This has made a significant difference as you would expect

Because of my fiddling as per above the closest coil I have to the 22mH/54mH spec measure currently 20.2mH/55.3mH with inner and outer copper strip connected across L1. I note also that the  Following is its result. Yellow trace is CN1. Blue trace is CN3.

I now have some resonance appearing L1 and only required the drive voltage to be 2.5 Volts which is down form 4V.

Now heading in the right direction at least.

Hello Brian,

Great Work Thank You for Sharing!

The key is: Don't give Up!

Get the right Amplitude and the right Frequency, and the Resonance Required, and the rest will fall into place! With little steps, make progress until this becomes an: Eternal Flashlight

This is, of course, part of Research. Replicating takes some work and sometimes solving possible errors made on the part of others is also required, unfortunately!

Thank You also to YoElMiCrO!

It is somewhat disappointing that it has taken nearly 2 years to pickup on this Error I made! I am sorry to everyone for this mistake!

Your Coils, try not to rewind, just add / remove turns as required. Its much easier that way! Try complete Coil swap between each Coil Terminal Blocks, and single Coil polarity changes to find the best performance. Changing values of components a little bit at a time makes for Steps in the right Direction.

Best Wishes and, after our chat, welcome back onboard!

P.S: I believe your Inductance is currently to low, small increases in Inductance will give you better waveform, in my opinion.

 

Brian posted this 06 November 2021

Hi Team

With the recent correction I have been working on small increases in inductance as per Chris's suggestion.

Thanks Chris for posting on your thread and example of the waveform to work towards.

The following is L1 26.8mH / L2 58.7mH on a 45mm OD PotCore. Copper strip either side of L1

There is additional noise on Blue trace when I connect the probe to CN1, so frequency shown is not correct, if you calculate via period it is actually 172Hz as per the second shot below

Yellow trace is CN1. Blue trace is CN3.

Same Core as above but Yellow trace is CN2. Blue trace is CN3.

The timing and amplitude of CN2 and CN3 is not too dissimilar to Chris's results, but still yet to achieve good resonance.

Further increases does improve CN3 waveform.

L1 29.9mH / L2 59.4mH. Yellow trace is CN1. Blue trace is CN3.

Looks like I need to add more to L1.

During the process I have also tried cores without the copper strips which seemed to have little effect on the waveform, but may be important once I get to the sweet spot.

Hi Brian,

 

Thanks Chris for posting on your thread and example of the waveform to work towards.

 

No, please, if you read, I said:

Little more work:

 

I did not say anything else, no claims or example made here, so please do not jump to conclusions. All I did was show my Waveform.

I am happy to try and help, but I do not wish to be taken out of context every time I post something. I get that you most probably meant nothing of it, but want to be clear, I am not making any claim or example here.

Best Wishes,

   Chris

 

P.S: Thanks for sharing! Excellent Progress I see!

Hey Brian,

I am going to speculate, I can not prove this, yet I have seen results, most of the time.

1/4 is 0.25, now the MC34063 IC has a timing inside the chip. again all this is speculation, but I believe, the chip switches at Time t, so Coil L1 must match the 1/4 Wavelength, and L2 is a Harmonic of the Fundamental. We have covered Antenna Theory already here.

Lets look at Akula's figures:

 

So, lets ask, what's the Output Impedance? We can only guess on statistics, lets use this chart:

 

 

Back to back, we have 30 Ohms approximately right?

Lets use the Aboveunity.com Member Calculator to see the Coil characteristics:

So, turns ratio, are 1 : 1.414, so we could say, 1 / 1.414 = 0.707 and 1 - 0.707 = 0.29278, so not quite our 1/4 wavelength... Which is 0.25. Confused?

I really wish someone would chime in with more experience than me to help and correct me when I am wrong!

There is some guess work involved, that's all there is to it! I am no expert, that's why I said what I did, I am no expert, I have to guess on things. I cannot set any example if I do not have all the answers, I can only try to help. cry

I am sorry, my lack of Electronic Skills, and lack of answers gives me, and all of us, a disadvantage, but I am fairly confident that's part of the answer.

Can anyone point out the issues I have with my Waveform?

Best Wishes,

   Chris

Hey Chris

Amazing that you bring that up. After re reading some of you material, re winding with 1/4 wavelength in mind was my next step.

I arrived at this a little more simply, but I do like your considered approach better

My conclusion came from your information on how to think about magnetic resonance with reference to wire length.

Many thanks for your help

Kind Regards

Brian

Hello Chris
What does it mean by


the MC34063 IC has timing inside the chip


It is the capacitor on pin 3 that determines the timing of the MC34063 it seems to me?

Hi Chris

For your waveform of an LED where your red arrow is located we are in the linear region of the curve when we know that an LED is not linear it is only a linear region that interests us in fact that which one can foresee a certain linearity.


For the impedance we must not forget that 'we only speak with sinusoidal shapes and different frequencies to calculate the impedance I am sure you know that. For the calculation of the LED it is a resistor (R) and not an impedance) Z).


I'm sure you knew that, maybe I misunderstood your question please explain?

Hey Jagau and all,

Yes, technically I am not correct, I have misspoken, so I need to put that bit better!

Pointed out the timing here and various other places, the MC34063 is a PWM Converter Chip, on the IC Schematic, you can see:

 

We can see that Pin 3 is the Timing Capacitor.

So, my statement:

now the MC34063 IC has a timing inside the chip.

 

Perhaps should have been: "Pin 3 has a Timing Capacitor that controls the IC Timing or PWM in combination with other features"

I hope this is better and more precise?

It is the case that Readers will need to read between the lines a little, to understand some of the comments I make! I am not always entirely fluent with 100% of the statements I make, although I do make effort to be. If I am tired, then sometimes some things are not always 100% correct, so please read between the lines somewhat!

Best Wishes,

   Chris

Yes, Jagau, I did not mean that Waveform, that's from Manufacturer website, not my waveform. cool

I meant the waveform from the oscilloscope screen shot I posted, none of the others. That's why I said: "Can anyone point out the issues I have with my Waveform?"

I meant this one:

 

That's mine.

Thank for the clarification

Brian posted this 08 November 2021

Hey Chris, I am not sure of the relevance, but the frequency at around 95Hz is a fair way short of the 269Hz shown in Akula's video.

Could this be corrected by reducing the timing cap?

Kind Regards

Brian

Chris posted this 08 November 2021

Hey Brian,

Experiment is always the best practice to learn, so I suggest do what you feel is best!

If it was me, I would reduce Inductance first, changing the the Cap will effect the rest of the Circuit. I think the Circuit is pretty close to complete. You have all the right Values of Components?

There is a relationship between the coils as pointed out. Focus on that when winding or modifying  the Coils.

The Answer:

An _ _ _ _ _ _ _ must be tuned for optimum Frequency Response!

 

An Antenna must be tuned for optimum Frequency Response!

@All Readers:

The answers are clear if one follows the correct path! This is a matter of Free Will, do you choose to learn from those before us?

Best Wishes,

What is a Scalar:

In physics, scalars are physical quantities that are unaffected by changes to a vector space basis. Scalars are often accompanied by units of measurement, as in "10 cm". Examples of scalar quantities are mass, distance, charge, volume, time, speed, and the magnitude of physical vectors in general.

You need to forget the Non-Sense that some spout with out knowing the actual Definition of the word Scalar! Some people talk absolute Bull Sh*t!

The pressure P in the formula P = pgh, pgh is a scalar that tells you the amount of this squashing force per unit area in a fluid.

A Scalar, having both direction and magnitude, can be anything! The Magnetic Field, a Charge moving, yet some Numb Nuts think it means Magic Science!

The great Nikola Tesla:

Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago by instinct or reason. It has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antheus, who drives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians, and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic? If static, our hopes are in vain; if kinetic - and this we know it is for certain - then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
