Bedini Tesla Switch DvD Questions.

[AdAn]

HI!
where can downloads video EFTV part 38 ?

[James McDonald]

James, small quantities of SB570 can be ordered from Mouser. However they are currently out of stock.

I ordered some SB550 from my local (Australian) online store. They'll be here today. The only difference is they are rated at 50V, whereas the SB570 are rated at 70V.

Hi John --

Yes, I know that you can order small quantities from Mouser but you will still wait 13 weeks before you
get any from them or from any one else for that matter. I had them quote me prices for 500 pieces before I
bought 1200 pieces from Arrow Electronics. I will have 1200 of SB570 diodes available for resale to who ever
wants them. They will be in my hands on 4-15-2015. If Tom C. wants to buy from me for his Tesla Switch kits
he will get a very special price. Buying 1 from Mouser Electronics costs 0.89 cents for 1 to 10 pieces plus the
shipping costs. Buying 500 pieces from Mouser Electronics costs 0.43 cents per piece plus shipping costs. The
1200 piece cost is 0.33 cents per piece. I will be at the 2015 Conference and will bring SB570 diodes with me.
I believe that John Bedini picked out the SB570 diode for the RMS voltage it is rated for. The SB570 is only sold
through Diodes Incorporated in Texas but they buy them already made in Taiwan under a different part number
(SR507) and have them marked with the Diodes Incorporated part number of SB570.

Hello all --

"John Bedini keeps saying on the DVD "Don't change anything". So that could mean use the SB570's.
The minimum order is 1200, so maybe someone could buy 1200 and we can all purchase from them.
With a lead time of 3 months."

I will have 1200 SB570 diodes on 4-15-2015. Anyone who wants to get some from me can after
that date. These diodes are only made in Tawain under another part number of SR507. I believe that
Diodes Incorperated buys them from Tawain and has them marked with their part number SB570.

when I whas searching info on the retroreflection I came across another document of Tom Bearden:

I gave several ways of possibly extracting (diverging into the circuit and using) more of that Heaviside energy flow. The simplest and proven way (COP = 18) is the Bohren experiment which simply places the intercepting "unit point charge" into resonance. Thus the Bohren resonating charge sweeps out a greater geometrical reaction cross section area in the impinging energy flow, and collects more of the otherwise "missing a static charge" energy flow adjacent to a static collecting charge.

If -- after it has passed the circuit -- you retroreflect the Heaviside energy flow component back across the same circuit, you will get an additional Poynting collection by the surface charges, and get more energy. If you iterate this retroreflection, you get an overunity process, IF you do not use the common closed current loop circuit which uses half of the collected energy to destroy the dipole faster that one can power the load. Instead, one might adapt Tesla's "one wire circuit" between two widely separated capacitors connected by a long conductor. The best way, of course, is Letokhov's "negative absorption of the medium" which is excess emission from optically active, highly scattering media.

(comming from http://jnaudin.free.fr/meg/tbinfos.htm )

Am I correct that the resonance inside the tesla switch or the one wire transmission is ment with the resonant point charge so the frequency can be influenced by the tesla coil or battery and not some frequency that is related to a charge itself and is always the same?

[bruno]

I forgot to mention that I'm not leaving out the existence of the negative resistors, because the use off iron dopped aluminium can extend the life time, maybe this is also for the materials used inside battery. But for now my first priority is understanding more off retroreflection. Why didn't I have such intresting lessons 20 years ago on school

Hello John K.,
Because I was not happy with the deviations of the 50/50 cycle and couldn't get it like I would, I took the 8051 to puls. Now I have just 1 micro sec switching on time and practically no deadzone (even looking on 1micro sec scale)on the front and the back of puls stage 2. When I get the circuit to work I can see what the influence is in working with the greater deadzone (in front and back of puls2) of the SG3524. My batteries stay much better charged now, but still no charging above started voltage. But it did happened to go higher when the puls changed from sine to block.
My batteries in the test setup used for this are 4 x (8x1.2V).

@Tom,
The only thing I can see is that through the oscilloscope mass current is drawn, altough I have seperate 1:1 transformer before the scope (measuring the TS output) and for the pulses to optos a Velleman usb pc scope (normally no influence from there).
It keeps me puzzling, because it not always happend and only with the old now defective 8051.
I now orderd a function generator because I want to study also resonance for the retroflective part, because I think it's more important then the negative resistors talked about. Because when you look in the book of Tom Bearden he states that one has to go in the nano second switching range to work with those, so a dead zone of 5 micro sec is like a snail who wants to cross the road in comparison. So therefore I'm now going in learning more about the retroreflection. Offcourse I can be totally wrong, 99 precent change even but I really noticed improvent with the better 50/50 duty.

I really would like to go to only use the SG but I need to understand what is important for the switch to work like it supossed to do. The 50/50 duty cycle as stated here previous on the forum is for me at the moment a proven fact, but I'm still learning and thank you all for the comments and help.

I also understand what you mean John. K with "not having a go at you" and I don't see it that way, for me this is serious matter and I want to think through on the why and how.

[John_Koorn]

bruno, why are you using an 8051? Don't want to detract you but didn't JB say not to change anything until you get it working?

Also, what type of batteries are you using? If they are 12v batteries and you are running them at 10.x volts you aren't going to succeed. Not having a go at you, just want you to succeed.

John K.

[Tom C]

the output side of 8051 is isolated from the hi side the opto. unless you are injecting more current on the output side of the opto some how (the current from the opto flows thru the base to collector to ground, that is where something may be added) you may be seeing more current to the base that is my only thought. I am not familiar with the 8051.
unless there is a floating ground somewhere.

Tom,

Strange thing happened today when I whas working around that point where the sine wave did go to block wave and the led's brightness was at it most brightest I've seen. The 8051 ic stopped working and after replacement I couldn't get that change from sine to block at certain frequency. While it was working with the old ic, I watched the puls signals on 2 scopes, one on the pulses to the optos and one on the output of the TS.
There whas no change to the wave to the optos, frequency 477hz, 50/50 duty with the old and the new 8051. The only thing I can think of is that there where harmonics but I looked with the spectrum analyzer and also didn't see any difference.
My point is that there is a way to control the optos to have an output signal almost double in power then with normal puls of SG. But I have no clue what did it. It's not that there is a problem with my optos because the new ic is again running for an hour, also the previous had no problems only that switching point.
To bad the ic stopped working because the batterie voltage made great jumps also when the led's where that bright. My batterie 4 went from 10.35V to 10.45V in half hour, the other (3) whas depleting but with the load changed, the other (3) batterie went to 10.45V and 4 whas depleting.

Now with the new ic 2 led's are connected to the output and battery voltage stays the same for over an hour. I took the frequency where the peaks of the sine wave start to get smaller (this was approx the point where the wave went from sine to block with old 8051)
Whatever the reason whas, I'm conviced that output can be doubled.

[Tom C]

Bruno,

sorry should have been more clear. with the potentiometer set to zero resistance(which puts the resistance at 4.7K) that in my mind is the T/S/ running as fast (wide open) as possible, the cap did not seem to charge as fast as when it was running slower, to the point where I can see the LED's flash a bit. that's all I mean.

I think there will be a place where the battery in the dump to location is charged the best.

I have not done much scope work yet, other than to look at the SG output to the opto's and a look across the LED's still not happy with how it is running. I am sure the battery you are charging plays a huge part in the circuit.

[bruno]

Hello Tom C,
What do you mean with wide open spot?

there definitely is a rate at which the cap charges faster and its not the wide open spot

Never tried to measure the output with capacitor, but when using led's I see some points in the frequency range where they suddenly light very bright. When looking on the scope I see the output signal changing from sine wave to block wave (what offcourse is the reason for the sudden change in brightness), don't now if this are resonance points because normally the frequencies should be the harmonic, or there are different frequencies for the different batteries? At the moment I'm looking into this phenomenon to be sure I don't have a problem with the switching.
Do you have this sudden changes when you change the frequency over a wide range?

[Tom C]

latest update,

after 2 runs on the units swapping batteries back and forth, all of the batteries are maintaining their voltages, nothing is increasing any more. I did a few experiments with loads. I ran a small bulb for a while, long enough that I would expect a drop in battery voltage, but they did not drop. charged and discharged a capacitor a few times. the capacitor would charge up to 4 tenths of a volt below the highest battery voltage. there definitely is a rate at which the cap charges faster and its not the wide open spot.

The best charging of the cap was around one 100th of a volt every second, so it took quite a while to get the cap up, with my digital meter across the cap. I was using a 330 uF 35 volt cap.

Hi Aaron,

Did you happen to purchase any of the Ronald Brandt estate? If not do you know who did?

Thanks,

Hello Paul,
No problem, so long as we all know my intention is to find the reason why mine TS is not working like it supposed to be, not saying that the TS does not work in general. It's my problem to get it tuned

@Tom C:
Very nice build, all succes with the charging.
Your's and others advise on the 50/50 cycle is very crucial I think because today I did some experiments with my 8051 controllerboard for the pulses and I have improvements.
My intention is to experiment with the 8051 and when working changing the sg output to do the same so that I end to the original circuit.
Today I changed the frequency in a range from 12 to 800Hz and saw different stages in the output signal with scope.
Going from puls to sinus and triangle on the output only by changing the frequency on the input (waveform was always 50/50 duty block).
Because there whas spoken of resonance, I thought to find that point by looking at the output wave form while changing frequency.
Problem is that I now have different reactions (going from block puls to sine wave and suddenly back to block...) so I don't know what change is the best for loading.
I think there's need to be a very critical balance between all.
When the components off another puls generator have arrived, I will do another check and when the same results occur I will make another movie with the changes off the output waveform in relatance to the input frequency.

It's not so easy until you know what to be looking for, so you get more and more respect to John,Tom,Peter,Aaron,.... for all the work they have done and even want to inform us on how they get it to work.
Today I could even pull the charge from one side to the other side and back when using 1 led with no other componets on the output (so only half wave is loaded), so I'm the last to say that it's not working but the first to say I need more to learn to get it to work .

Does anyone of you have the same occurence that when you higher the frequency the output signals goes from block to sine wave and then back to block with sudden increase on the output (brightness off the led)? For my TS it's about 500HZ and 800Hz.
