    Could those latest unusually bright/efficient flashlights,  that can be purchased online,  be used to make an    overunity-Self-Powered-Generator  ,   to power a few things,  a laptop, tv   (  don't know about powering a microwave oven )

   I assume that maybe their pulsing( frequency, resonance? ) circuits may have been a result of research on this site( and other sites )

   (  They say they require batteries,  is that just to pass  technology-suppression protocols ,   or do they actually need batteries,    or do they only need a modification to make them   self-powered   )

   If a cheap one was found online,  would it be possible to connect a number of them together to power a few things,  a laptop, tv   (  don't know about powering a microwave oven ),   could someone with very little circuit building experience do that

Is this what you are talking about?
https://www.amazon.com/Portable-Handheld-Flashlight-Adjustable-Resistant/dp/B00R5VM3FM


It’s not “self-powered”, it needs its batteries and won’t power much else.


Has ultrabright LEDs and a built-in joule thief.
Saw them the other day when someone in the JT thread asked
what the circuit is used for.


Turns out JT’s have many new commercial applications


If that’s not the right flashlight, can you link to the one you mention?

yes,  that's the type I'm referring to

I assume that all of these new-generation flashlights using JT's and LED's must be nearly identical  ,    I don't know if this is just pulsing,    or does it involve an  'LC circuit(resonant circuit ),   and / or,    also an overunity effect proved in some types of  LED's

   I notice on your channel on youtube,  you have at least one  self-powered  solid-state  device  .

(  I suspect that JT circuits,  was one of the  solid-state  designs that have achieved self-powering,  so I thought that maybe one of these models of flashlights :
       -  can be modified to be self-powered
        -  then connect a number of them together,  to power a laptop, phone recharger, power a tv (  I doubt powering a microwave could be achieved )
         - In my case,  it would allow me to rent/live-in a building where they are not allowed to connect the electricity( since they cannot pass the wiring inspection,  due to old wiring ),  so rent a different type of accommodation for my own reasons    )

However, I have almost no experience building circuits or anything like that( only 2 radio-shack circuit-kits on breadboard, no soldering,  long ago ),   so I'm looking for an option,
    -   to buy things that are already constructed, 
    -  so I could maybe achieve tiny modifications to make them   self-powered,   
    -  connect a few together,  and power some low power home devices

    actually,  the only things I would need to power would be a phone-recharger,  and a  small version of a laptop( netbook ),  since I can just connect a  tv-ariel  to a small-usb-converter,  and the software displays tv

None of the electronic devices on my YouTube are “self powered”


The closest would be the Earth Battery, but those deplete over time
and have to regenerate.


 
there are ways to ‘tune’ the frequency of a JT to achieve extremely long
run-times with a mostly-dead battery, but even those have to replace the
battery 2-3 times per year.


I have seen claims of the JT used to charge batteries, but I have yet to test this
method. (I remain skeptical of such claims)


They can be highly efficient, which is a step in the right direction.
There are “how-to” instructions available if you do a google search
I would suggest replacing the resistor with a variable one, for tuning.


You can recycle used batteries with the device, to drain the last bit of energy
Or greatly extend the life of new batteries.

As far as the “overunity” claims of these new ultrabrights


This is based on an old assumption of the power conversion
of Watts to Lumens.
Which has been broken by the leds


The “actual power” emitted as light is still less than what is consumed
We are just able to make more Lumens per Watt than previously assumed


JTs operate by pulsed DC current, so the LED flashes rapidly
Often it can turn back on before one of two things happen
1) the response time of the human eyes (>~60hz)
or
2) the cut-off time of the diode (time it takes for the led to turn off)
Both of these things make it appear to emit steady light.


But they are not providing constant power, it is pulsed.

Older and cheap LED flashlights used pulsed modulation but those tend to create a strobe effect when moving them or moving something in front of the light rapidly so they are not used much now unless the pulse frequency is very high.  Over the last 12 years LED's have become more efficient every year but are not overunity.   You can actually put an LED in sunlight though and get some power out of the LED but not a very useful amount. 


LED's are obviously way more efficient than tungsten filament bulbs and even more efficient than fluorescent bulbs.   Anyone who has not converted their house lighting to LED should really do so.  It can pay for itself fairly quickly.   60 watt equivalent bulbs in LED can be had for $1 or less at many places now including Walmart.   


postingsite,  also since you are mentioning powering something with a flashlight I assume you mean to shine a light at a solar cell to create power for a laptop etc.?   If so then the big problem with that idea is that solar cells are most often less than 20 percent efficient so no matter how efficient the LED light is you will lose a lot on the solar to electric conversion.

  no, I'm not interested in any solar-cell effect, in regard to these flashlights

  I thought that since these latest flashlights contain JT like circuits,  so they are high-performance  JT like circuits pre-built(  since I cannot build anything ),    that it may be possible to,  for example :
    - remove the LED's(  throw the LED's away ),  connect the wires from the flashlight that went to the  LED's,  to a Coil( A ) wrapped around an iron-core( cylinder or donut shaped iron-core),    then wrap another Coil( B ) on the other end of the iron-core, or even onto an opposing  iron-core,   and  use the  output current generated from Coil( B ),   to power the  JT like circuit in the flashlight,   by removing the batteries,  and attaching it to the terminals.

NOTE - Wikipedia still describes an electromagnet as having the following effect :       
    https://en.wikipedia.org/wiki/Electromagnet
       "A core can increase the magnetic field to thousands of times the strength of the field of the coil alone"

I only have ideas for the very basic principles,  to make a self-powered-generator,  not how to properly and safely power a phone-recharger,  and a very-small-laptop

Here is some more detail of what and why I wanted to make it -
______
(  I suspected that JT circuits,  was one of the  solid-state  designs that have achieved self-powering,  so I thought that maybe one of these models of flashlights :
       -  can be modified to be self-powered

You can rest assured that these flashlights require batteries to operate.

Ok I misunderstood your intention with the flashlights.   I've been a flashlight collector for many years and have a ton of LED lights.   Most have such miniaturized circuit boards I doubt you will want to tackle using them.  I can't say I've seen any sign they use JT type circuits either but I could be wrong.   I've had quite a few lights taken apart and most use simple circuits to regulate the voltage output to match the LED voltage rating and some can vary the current for different brightness levels but as smoky2 said they all need batteries and while a few people here made some super high efficiency JT circuits I don't believe any were OU with one possible exception I know of and that one was never able to be duplicated.   You'll probably do better to build your own JT circuit or even get one of the many JT kits available (at places like eBay).  Beware though 'Joule Thief' has become somewhat of a 'buzz' word often used to sell items like DC-DC converters which may not even have real JT circuits and those that say they don't have an inductor are most likely not a Joule Thief.

   Actually, I don't even know if a JT circuit would be required for my idea,  since you mentioned earlier :

Older and cheap LED flashlights used pulsed modulation but those tend to create a strobe effect when moving them or moving something in front of the light rapidly so they are not used much now unless the pulse frequency is very high.   

   maybe one of those very dated LED flashlights would do,  for pulsing coils on cores,  etc

   ( I once had one of those very common small keyring-flashlights, that only had one LED,  and a button-cell battery,  no other circuitry    )
_____

   just to add,     an alternative to using these circuits( if you want to try and use the ones from a flashlight ) to power coils on cores,  would be to use them to power :

   A TPU like device,  basically,  is based( from the little I know ) on the principle of winding a wire( Wire-A, which will conduct current ),   around another wire( Wire-B, which will also conduct current ),     so that both the coil( Wire-A ),  and the core( Wire-B ),  will both carry the current.

     This may work by the coil( Wire-A ),  forcing the core's( Wire-B ) field back into itself( back into the wire ),  and thereby inducing( or generating ) surplus current into the device.

    I don't know if there's both,  pulsed,  and  non-pulsed versions of  TPU devices

     There is an interesting wiring diagram on the web-link below, that link takes you straight to the exact post that the diagram is on,   but you would think it would be easier to just design your own circuit for such a simple idea
    http://overunity.com/712/the-master-of-magnetics-steven-mark/msg63797/#msg63797

     Another interesting wiring diagram for the TPU,  but I can now only access that diagram by using the following  command in  google-image-search ( Note,  by using the  "site:" command in the search,   to only search in the specified webpage )

the primary of the tpu is a multiple parallel path receiving antenna
tuned to a specific frequency
and with an intrinsically low resistance
the secondary coil is a capacitive inductor
and the 3rd is an inductively coupled output
the 3 act in resonance, to amplify the input signal


The input signal is from a capacitance larger than that of the tpu.
Your source must meet this requirement


TPU is not "self-powered"
Steven Mark tells us what his source is.
The capacitance was calculated for us by Tesla.


Winfred Schumann gives us the fundamental frequency


SM therefore gives us an (parallel) antenna length of 2x(1/f)
Where x is a whole number integer
And F is 7.83
