@BediniBattery,
below is a quote from PesWiki about a South African company invention which uses the Tesla Switch
http://pesn.com/2012/03/28/9602066_S_Africa_Company_Discovers_Problems_in_Alpha_Testing_their_Fuel_Free_Generator/
Does your improvement resolve the problem mentioned in this quote?

Hello BediniBattery,

thank you for the very nice circuit work you have done.

A video demo of your functioning circuit with test data would be required to get replicators interested.

Sorry!... that's just how it is

@Qwert,
 
I am not associated with BediniBattery and he can write anything
he wants in reply to your question, but here is my take on it;
 
From pictures the SA company seemed to use a physically small
Gel-cell battery with *multiple batteries in the same plastic pack*.
This allowed for them to have a physically compact final unit
and a neat design to handle redundancy of the batteries.
 
Except – if you know anything about acid/lead storage batteries,
you know that this is not the right way to go for a unit designed
to generate continuous electrical power. As the batteries will
have to have continuous operations at a high power densities.
Power as watts per cubic inch of given battery volume.
Also Gel-cell technology especially is not the right way to go
for this use.
 
In acid lead batteries physical robustness and large size are
hallmarks of large power handling capacity. So problems with
the SA design should be expected…And the expected solution
would be much more robust battery and therefore less likely
to fit in a diminutive physical arrangement. But this would
most likely not have fit into what the SA company wanted
to see in terms of system size.
 
If one wants this capability most likely one could solve
the energy problems by using deep-cycle discharge batteries
often used in marine trolling or lift truck operations.
 
---
 
After having said this;
 
I take exception to part of your question in that it is not likely from
the description in the SA post that their unit is actually a simple tesla
switch.
   
--- 
I was going to write a detailed post about what I think is missing from BediniBattery’s
system design for use as a long term power generation system (if it works?).
 
(1)That is one microcontrol processor for long term system configuration
of this unit. This could also easily indicate the overunity energy state of the
system too.
 
(2)Using multiple CMOS NE555 and 75L05 low power positive 5volt regulators to
do a voltage to frequency converter circuit for each battery with an AC multiplexer
to allow the microcontroller to have instant isolated access to the approximate voltage
of all batteries. This Tesla Switch does not use HV pulses, which is a boon to this
form of voltage readout.
 
(3) Motor powered high current relay switches to allow the microcontroller to
be able to reconfigure the six batteries to swap positions between the driver
and recharge positions to control battery wear.  These could be purpose
constructed.
 
(4) A microcontroller controlled load resistor to allow for the breakthrough
of the float-voltage on batteries that have just been charged and to allow
the controlled discharge for energy for determining overunity status.
 
 ---
 
So I think that you would agree that with the above two items this should answer
your question positively.

Circuit Design On A Small Budget
« Reply #4 on: June 11, 2012, 04:48:03 AM »

I would like to point out to everybody that nobody is funding or supporting me to build this overunity experiment.

I am on a tight budget & have to keep things as simple as possible.

I am building the circuit to prove one way or another, whether this circuit does actually provide free energy, for constant use.

As far as the choice of batteries to test is concerned, there are many different lead acid batteries, Gel Cells, Car Batteries, 2 volt batteries, 6 volt, 12 volt also NiMH or other types of home made battery.

You would have to set the maximum charge voltage by changing one of the zener diodes, slowing the switching speed when they get fully charged.

The load current does not need to be excessive for overunity to be achieved, but rather tailered to the size of batteries you are using.
I will be testing small batteries as well as large batteries to see what happens with different loads.


The 4N25 works best around 270 hz, but after that it begins to introduce dead time, where non of the mosfets are turned on.
If a faster switching speed is required, look for a faster opto isolator having a similar specification.
1Khz is achieveable but there is a small amount of dead time, which may or may not make any difference.

Some of you want to check the voltage of one of the 6 batteries while the circuit is running.

3 of the batteries are wired in series, for between 1 to 10 milliseconds, so you could measure the series voltage by storing it in a capacitor.

Most likely you would get an average of the 6 batteries doing it this way.

3 of the batteries are wired in parallel, so you can measure the parallel voltage, but again you can only measure the average voltage of all 6 batteries.

If you wanted to measure each battery seperately, you would have to turn off all of the mosfets & stop the circuit operating.
You can measure the batteries seperately after you have run the circuit for a few hours, if they are still charged, the circuit works.

The circuit has been constructed using analogue components, since these are cheap & easy to get hold of.
I don't understand why you would want to use a microcontroller & use relays to switch the batteries, this doesn't make sense.


If you are unsure about whether you are getting overunity, think about this,

If the batteries stay charged while you are discharging 30 amps through the load, & each of the 6 batteries only receives 10 amps charging current, where does the 20 amps free energy come from.

Each of the 6 batteries has to discharge 3 times as much current as they receive during the charging process.

The 6 battery tesla switch has to work much harder than the 4 battery tesla switch to achieve overunity.
This particular circuit wasn't patented & it was never constructed using modern components as far as I can tell.

I have nothing to do with the South African company who are doing their own free energy thing.
I cannot comment on how they use or abuse their batteries.
Batteries do not last forever, a few years if you are lucky.

Thank you BediniBattery for informing us of your position concerning your proposed circuit.

I wish you the best and look forward to your success. Please let us know one way or the other how it works out.

...


 
First...when you build this circuit please come back here and tell us unambiguously whether
it seems to work or not...that will be a tremendous service to us and I understand where you
are coming from. The Tesla Switch which does not use HV pulses and therefore has some
things going for it, if it works. On the other hand if this configuration doesn't work well there
could be some things that would use your circuit that I think could be made to work.
 
The six battery case might be expected to work better then the four battery case
because charge voltages are higher.
 
A free energy demo versus powering a house 24/7 are two different things though.
Most of time a more robust battery will be called for to provide for the large
currents/powers involved. As I like to say; "batteries were not designed to be used
as reactors", but the more robust ones might not fair too badly in that use. The thing
I am trying to point out is; that there *are* specialized batteries built for this kind
of high power service.
 
The microprocessor is not really for the demo stage of this circuit but would be used to keep
track of each of the batteries individual characteristics if they are the larger more robust
type that you care about maximizing the life on for each one. I can not say that having a
battery in the driver or the recharge position will effect it's wear life or not, but one might
suspect that it would. In which case the microcontroller could be programmed to swap
things around on an arbitrarily long term basis. Also there may need to be a quick load
put on charge batteries to break through the float charge voltage to get to the real
underlying battery voltage.
 
A question is would it be better to have a very small inexpensive battery that you
don't have to be concerned about but have to replace every few months or a more
expensive one that you want to do things for to make it absolutely last as long as
possible.
 
These are some of the questions that one would be expected to be asked of an
experimenter, but once he determines the answers the design could be much more
direct. In reality relay switches are designed to be used in a high voltage pulse
mode case but I would not want to exclude that possiblity in a first design.
 
Yes, thank you for sharing and please come back and let us know what works!
That is the thing I think we have been missing to date.

4N25 Opto Isolator Preferred Component Values - 2857 Hz Switching Speed
« Reply #7 on: June 22, 2012, 09:27:24 PM »
Preferred component values for the 4N25 Opto Isolator
----------------------------------------------------------

The zip file download date is - 22 / 06 / 2012

- http://www.mediafire.com/?itj2dll96tzy2 -

-------------------------------------------------------------------------------------------------------------------------------------------------------------

To achieve a maximum switching speed of 2857 Hz, the opto isolator has to be driven harder to make sure that the gate turn off voltage falls below + 2 volts.

To test the 4N25 opto isolator performance, you need the following setup.
A power supply voltage fixed at 12 volts for both the diode & the photo transistor.
The diode requires a 270 ohm series resistor & the transistor collector requires a 1K6 Ohm series resistor 1/4 watt.
The diode is driven directly from the output of the 555 timer, similar to an LED.

With the resistor values selected, the maximum photo diode current will be 40mA & the maximum transistor collector current is 7.5mA.

The absolute maximum continuous forward diode current is 60mA with a forward drop of 1.13 volts, taken from the data sheet.
The photo diodes are on for 50% of the time, with a current of 40mA, which means an average current of 20 mA flows continuously.
The diodes are not driven at their maximum ratings.

There are a total of 12 opto isolator circuits used to construct the 6 battery tesla switch.
Only 6 of the opto isolator transistors are turned on at any one time, each one draws 7.5mA.
The 555 timer astable draws a maximum of 40mA with one LED.
The power consumption for the isolated power supply is (7.5mA * 6) + 40 mA = 85mA


The diagram shows 6 photo diodes in series & one series resistor

To calculate the series resistor :

12 volts - ( 6 * 1.13 volts ) = 5.22 Volts

5.22 Volts / 40mA =  130.5 Ohm 1/4 watt

Two series resistors 100R & 33R is sufficient, both are 1/4 watt 1% metal film.


There is a 470K variable resistor in the 555 astable circuit which can be used to adjust the frequency to some extent but its main purpose is to maintain a 50 % duty cycle.
Adjusting this resistor seems to affect the pulse width more than the frequency, so select the right capacitor to set the switching frequency instead.

The smallest capacitor that should be used for the astable circuit is 10nF & this gives a stable switching frequency of 2857 Hz.
The square wave cycle time is 350 micro seconds, the mosfet on time will be ( 175 micro seconds - a dead time of 40 micro seconds ) = 135 micro seconds of on time.
The dead time results in the mosfet not turning on instantly.
At a switching frequency of 2857 Hz, 1/4375 of the mosfet on time has been lost.

There is nothing you can do about the dead time.
If you want to eliminate the reduced power output issue, you have to increase the load current to take into consideration 1/4375 of the mosfet on time has been lost.
Reducing the load resistor by 1/4375 will fix the issue.

You can reduce the switching frequency if required, but a dead time of 40 micro seconds will still exist.

The output voltage from the tesla switch cannot be guaranteed due to the need to reduce the switching frequency considerably when the batteries become charged, thus the dead time will be removed periodically.
You will have to use some kind of switch mode power supply to regulate the output voltage.
Output capacitors & voltage regulators should be used to power sensitive loads.
The mosfets should ideally only be used to drive resistive loads to eliminate any heating effects caused by back EMF.


The 4N25 can be used within a switching frequency range of between, 2857 Hz or less.

Lowering the power consumption of the drive circuits means that smaller batteries can used to build portable free energy devices & there is less instability & stress on the toroid which is used to create the isolated 12 volt supplies. Thats the switching part of the circuit designed & tested, now the construction begins.

If anyone wants the pcb design or requires a pcb to be made, you can contact me via facebook,

- https://www.facebook.com/media/set/?set=a.234713343271460.55413.100001983889140&type=1 -

- All of the electonic parts are available via  http://www.rapidonline.com/.  or  http://www.ebay.co.uk/sch/i.html?_nkw=electronic+components

This is a big project & has turned out to be quite expensive as there are quite a large number of parts to buy & make, partly so that the pcbs can be produced properly.
The expensive parts are the high current switches, thick copper braid, lots of mosfets, heatsinks, transistors & batteries.

I am still short of a few items, so I won't have a working circuit until August 2012.
If anyone can donate that would help me build quicker.

Prebuilt PCBs can be purchased in August 2012 for UK customers, so if you are interested, let me know.
Smaller, more compact PCBs will be possible as soon as the practical tests have been completed, to see how much heat the voltage regulators make.

Tesla Switch - Update - 14 October 2012 - I Know My Galactic Family Is Here
« Reply #9 on: October 14, 2012, 06:19:33 PM »

http://universallyaware.ning.com/profile/Snail007500

I have managed to complete all of the solid state switching circuit design & the pcb layout but have not yet proceeded to build the free energy device.

The main issue is funding, however there is also now a time issue relating to the end of 2012 which cannot be ignored.

December 21st 2012 appears to be the end of time as we know it, its the 5th dimensional shift.
You can find out more about this on 2012Scenario.com website or blogtalkradio.com/inlight_radio

A disclosure video has been created on youtube  :

I Know My Galactic Family Is Here, Do You? (UFO Disclosure)

https://www.youtube.com/watch?v=ulWK-Ni-xiw

--------------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------------

This video has been produced and released by InLIght Radio for you to share with all your family, friends, neighbours, work colleagues - and the world - to let them know that our Galactic family is here. Keep sharing!

You can now enjoy and share this video with seventeen different language subtitles thanks to Luisa, Christoph and the Family of Light Translators (for English, use the "English" option, not the "English-transcribed" option). Turn on Captions using the symbol on the right-hand side of the bottom menu bar above left and select your language. For English subtitles, use the "English" option, not the "English-Transcribed" option which is computer generated and inaccurate.

For too long, our governments, military leaders, religious leaders and the mainstream media have hidden the truth of our galactic history and the real presence of our star brothers and sisters from us. Not any more! Our Galactic family is here - and has been since the beginning of time, and they come in peace, love and friendship to help us fix our planet and create the world we all deserve - a world of peace, pristine environments, equality on every level (racial, financial, sexual) and, importantly, love.

This video features the InLight Radio on-air team - Graham Dewyea, Steve Beckow, Geoffrey West, Linda Dillon, Dave Schmidt, Sierra Neblina and Stephen Cook - as they share their personal disclosure stories and ask you to share this video with everyone you know via your social media and online resources. We know our Galactic family is here - do you?

--------------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------------

To complete the Tesla Switch project I still require £400 in donations. (UK Cheques are preferred)
The project has been put on hold until I can save up. - Date - October 14th 2012

--------------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------------

The solid state circuit is difficult to construct & the lead acid batteries are heavy & take up a lot of space.
The mechanical switching design is recommended if you intend to experiment with this circuit, there as far fewer problems to deal with.

The mechanical switching design has the advantage of being able to use higher voltage batteries as opposed to the solid state circuit which is limited to about 12 volts per battery. You need suitable machining equipment to build the rotational mechanical switches properly.
The solid state circuit was able to switch the batteries at over 2Khz using opto isolators & mosfets.

If a mechanical switching device was used, the battery switching frequency would be based on the RPM & the number of complete switch contacts.
The mechanical rotational speed would be 6000 to 10,000 RPM = 100hz or 166Hz
The more contacts you add per revolution will mean the battery switching frequency can be increased.
The motor can be powered off the same batteries you are using to power the load.

If 4 contacts per revolution were used,  6000 to 10,000 RPM = (100Hz or 166Hz * 4)
                                                            =  400Hz or 664 Hz

A high speed brushless motor is definitely recommended as it can be speed controlled.

There will be a small percentage of dead time between the switching.
The dead time will be approx 20% of the on time.

You can make use of pulleys to step up the rotational speed & use a slower running motor with higher torque.
The mechanical switches replace the solid state mosfets.
Use the solid state circuit diagram to work out how many switch contacts you need.
