Is joule thief circuit gets overunity?

[SchubertReijiMaigo]

This is the second attempt to do the 2 stage JT.  To my surprise, the Input Vpp was higher than the Output Vpp.  The COP was -1.24.  It appears that the 2 stage JT circuit has a much more complex feedback mechanism than simple addition.

MORE RESEARCH NEEDED.

Comparing a peak power doesn't give you the total energy for a cycle (say one second for example).
You need to make integration (computing the area of the power of your signal in your graph).
If the area of the output power is superior then you have OU, I say that because you can have a huge peak power during a brief time and not having OU ! With a peak power you can't see OU.
I never understood why you concentrate so much on peak power but in reality energy is also linked to time: How many Joule I have consumed during a definite time and how many I have produced during that same period !
Although I'm not a specialist but why not try that:

What can you do with Board 71 (and Board 33, 38, 39 etc.)?

Apparently, Board 70 was an exception.  The Output Voltage, Current and Power were many times higher than all other boards from Shenzhen.  It will be sent back for detailed examination.

Since I already twisted out the LED on Board 71 so that all Output goes to the connected LOAD at B1 and B3, I decided to test its limites.
(1) It can light up the 12 LED strips that normally will require 12V DC to light.  That is not surprising as I had demonstrated that before.
(2) It can light up many such strips.  I used up all the strips available in my bedroom.  A phone call to a tester in Hong Kong also lighted up many thousands of LEDs in such arrangement.  The joke at the moment is that we may be able to light up the millions of 3V LEDs in the whole retail shops in Shenzhen.  We shall see.
(3) The Input is from the DC Power Supply at 2V and too small a current to be indicated.  The reason of keeping the voltage at 2V is not to burn out the 2n2222.  I shall be more daring with the 2n3055.

I shall double and triple check my oscilloscope analysis before posting it.  It is too unbelievable.....  Is it possible that such a simple board can light up millions of 3V LEDs?  Can it be compared to the match that light up (burn up) the entire forest???

@poynt99 and other testers:  the Board is going to be much more interesting than simple OU or showing negative average input power.  Have fun....

Now the oscilloscope analysis on Board 71 after double and triple checking.  There is little chance of experimental or equipment error.

(1) The New COP is -6.47.  The negative sign comes from INPUT.  This is a large increase in COP.

(2) There are sharp Negative Output Current peaks.  The more LEDs I put on, the sharper the peaks.  No such negative current peaks were observed with just 1 LED.  It looks like when the board needs more energy, it automatically goes out and gets more - showing that fact from the negative current peaks.

(3) The Average Input Power is still negative and the numerical value changed little.  We are NOT drawing more energy from the DC Power Supply to light many more LEDs.  Is the source of this extra energy - lead-out energy?

With the 2n2222, the LEDs did not reach the full brightness.  Will use the 2n3055 next.  Can the 2n3055 board be the more powerful match giving more brightness?  We are not restricted to the 2n3055 or transistors.  Other rapid pulsing mechanism may also be fine....

Another tester from Canada.

Dear XXX,


Two 2n2222 oscilloscope test ready boards are on their way to you.  Make sure you read the thread in overunity.com to know how to test them.  The two boards can be put into  a 2 stage fashion to clearly demonstrate OU and negative input power.  Get help if needed.  Email me your results or post them on the forums.


The result will convince any venture group or research organizations.  Follow the overunity.com thread.


May the Almighty guide us to benefit the World.
