That's really cool! I hope he makes some money. The 3d printing is really nice.

Those pot cores are tiny!


Meanwhile, in my loopstick variant I have found a  "new low" transistor. It starts at 0.425 V and stops at 0.100 volts (LEDS just out, but still oscillating.) Finally stops completely at about 0.089 V.

I don't know what the transistor is, though! It is a TO-92 plastic case, marked

1802
N711
EBC

and has a tiny M in a circle on the back (rounded) surface.

Nice of them to give the pinout anyway. Does anyone know what this transistor is? I've done the usual googling and can't identify it.

look at the small .pdf file   Small Signal   Germanium *PNP*   *min. ce = -0.5Volts*    Shows a metal TO-18 package
but that could change. They often left the "2N" just so they can mark the tiny package.

Extreme prototyping:

I kind of replicated Lasersaber's 3D-printed-torch (https://www.youtube.com/watch?v=pDH4ahCBCAs).

It is not 3D-printed, not portable, has a different coil and the three white LEDs give a fairly bright light for about 3 minutes for three turns of the hand crank.

I showed my SJRLooper circuit and the coil here:

http://www.overunity.com/14591/lasersaber-strikes-again-a-joule-thief-king/msg406424/#msg406424
(the resistor is 1 M instead of 20 M to make the three white LEDs shine brighter)

My hand cranked stepper motor charges the caps till the Voltage reaches about 15 Volt, then the red LED starts to light up and to syphon off the charge. The red LED indicates that one can stop cranking. Three turns of the crank are enough to charge 5700 µF to about 15 Volt. Then the three white LEDs shine nicely for about 3 to 4 minutes. It takes about 7 minutes till the three white LEDs are completely off.

My replication is just an experiment, not really useful.

Some time ago I made a video about my hand cranked stepper motor generator http://www.youtube.com/watch?v=qec_qsDseCY .

I can envision a nice addition where you have an auxiliary capacitor bank that you connect to the flashlight so you could hand crank up a much larger capacitor.  Then you could read for a 45-minute stretch before having to crank, as an example.

It's the concept of a "DC house" for poorer countries.  You make it a modular concept.  A deluxe very large capacitor bank and an some kind of foot crank generator that could be cheaply and mass produced would be very interesting.  Then you could be energy self-sufficient for your lighting, have a radio or small low-powered LCD TV, laptop, wireless Internet, recharge your cell phone yourself, etc.

Some numbers about a "foot crank generator":

http://spectrum.ieee.org/green-tech/conservation/these-exercise-machines-turn-your-sweat-into-electricity

An elite cyclist can produce more than 400 watts, more than half a horsepower, for an hour or more at a stretch. But the average person, even somebody in good shape, can generate only 50 to 150 watts during an hour of strenuous exercise. If you could capture that power to produce electricity, what would it be good for? Not much, really. It could power a television set for about an hour, which might keep you entertained while you pedaled away to produce the electricity in the first place.

My opinion:

With an "exercise bike type of generator" you can maybe generate 10 Watt hours before being pretty much exhausted. If you make a real effort for an hour, may be 40 Watt hours. This would give you a decent LED lamp which uses 2 Watt for 5 to 20 hours. Still, pretty useless and the bike would be bulky.

Two 100 Watt solar panels (which cost about EUR 125.-- each) would do much better even if you only have 4 hours of sun.

I think that EUR 1000.-- will buy a solar panel system including electronics and batteries which would cover real lighting and a laptop every day if you install it yourself in a straight forward manner. That means you will have two or three rooms with a 4 Watt LED lamp (at 12 Volt) and in one room the 220V / 300 Watt converter with a socket for the lap top. Alternatively to the laptop you could run a smaller TV set and whenever you want a radio or CD player.
The real problems are refrigerator, washing machine, dish washer and cooking, and you can forget heating or air conditioning.

What I want to do with my hand cranked stepper motor:

6 x 4700 µF 25V caps (which I bought some years ago very cheaply) can be filled to 15 Volt with about 10 turns of the crank, which would give 30 minutes light from the three white LEDs. This light allows to read when holding the book at 40 cm from the LEDs or it would be lighting enough not to fall over things in a room at night. The light is comparable to what Lasesaber shows with his 3d-printed blue flash light. I just tested it. I will use a Ferrite toroid instead of my nice big transformer core or will buy some of these little Ferrite pot cores if the toroid does not work well.

This is nothing fancy and the usefulness can be doubted. But I have the materials at hand, why not build it?

Greetings, Conrad

We should be asking Lasersaber, if he would kindly crank the setup for the three seconds,
then measure the voltage on the capacitor and tell us the capacitor's capacity.
Then show or tell how long it runs and the voltage across the LED's during the run.
( I trust him to just "tell" as he's been truthful with me, before when I asked a question )
Then we can see the efficiency of the device in operation.

I have a capacitor across my LED's so I can measure a stable voltage across them, which
is not that important if we know the stored energy and the run time, but it does help us
to know how bright they really are.

Reflective cones around the LED's should make for more efficient light output,
maybe he can design some reflective backings for his torch to improve it's light output,
if he hasn't already done that of course, he may have that covered already I could not tell.

..

Anyway, I hope Lasersaber does recoup some costs from his prototypes, he is an honest guy, I just wish he wouldn't allow so
many people to think his circuits are OU, I don't think he does enough to dispel that myth.

About the odd circuit behaviors, I've seen similar to some of the things you mention even with a two transistor feed back circuit at
low voltages and different on times ect. , one thing i noticed which I found curious was when it appeared that the base drive at low voltage
could not hold the transistor "on" for the normal pulse length of time as when at a slightly higher voltage, the effect was that the transistor
seemed to turn off momentarily then turn back on for the rest of the "normal" pulse length, there was no real discharge or spike
because the transistor came back on fairly quickly. I imagine that when the transistor prematurely turned off then the supply was
unloaded so the voltage of the supply rose enough to turn the transistor back on again before the "regular" pulse time ending.

This was noticed at almost "stop working voltage".

Hi!
I’m Shekhar from Calcutta, India.  I’ve recently been interested in the so called “Free-Energy” (or ZPE) devices, especially those which claim to provide substantially higher  power output than the input power, so that they can  operate in  self-running mode.  I am a member of a local  organisation that works among  poor slum-dwellers and one of our main activities is to develop cheap, clean and useful source of Alternative Energy and fuel. 
I visited many Net-forums, read quite a few good books (e.g., Patrick Kelly’s marvellous compilation), watched quite a few Youtube videos (a lot of them quite obviously fake – making fake films has become an art these days) .    I want to share my observations on this whole topic. Here I go: 
1.    Everybody takes the name of Nicola Tesla, talks about his devices and copies and pastes  his patents and schematics in every other article. It is all very well, but please tell me the name of any living inventor who has replicated even one of his devices successfully; ‘successfully’ means the device is providing ample power and gain to justify its practical utility ; charging cellphones and lighting a few LEDs are not something that Tesla himself would call ‘success’, I guess!

2.   Certain names are very familiar and quite justifiably respected in ZPE forums and articles – Mr. John Bedini being one of them.   Men like him are inspirations to many free-energy enthusiasts and replicators. Unlike fraudsters who are out there to make a few quick bucks by selling ‘Free-Energy’ dreams to the gullible millions, people like Mr. Bedini and others are true-blue scientist-inventors who share their secrets with the society.  But let me put just one question to all of you – is Mr. Bedini employing the output of  his inventions to provide even 20% of the power required in his own house ?  We all talk about ‘freeing ourselves from the clutches of  Big Energy and Big Oil’ by doing away completely with Grid electricity, but is it not the duty of the  leaders to show the way? (I myself use biogas from kitchen waste to cook my food so that I can recommend the same to the poor slum-dwellers).

3.    I am a middle-class Indian and like most Indians, I do not waste and cannot afford to  waste power in gizmos like Washing M/c, Vacuum cleaner, Air Conditioner / Room heater, Microwave Oven, Car Battery charging, Water heater etc.  My power requirement is very low compared to an average citizen of the ‘advanced’ (?) West!  Can someone tell me how to build just a 1 Kw. Output ZPE device that would run on a rechargeable dry-cell battery and recharge the battery from its own output? Please note that I want to hear only from someone who has himself constructed and is using himself such a device. In fact, a slum-dweller  typically has one ceiling fan, a few CFL lamps and a TV set  to supply  power to, so mere 250 W output will do just fine!

4.   There are many patented devices that simply don’t work (like Daniel Cook’s battery and Leal-Barbosa transformer). Yet nobody is telling the truth. Even when replication fails the poor replicator blames himself and certain other aspects of the materials!  Often he is too ashamed to admit failure, and so he provides spurious proof of his ‘success’ – who is going to verify his claims in cyberworld? There are many quite astounding devices like the Georges Mourier’s COP=10,000 Motor/Generator, patented in the US. I often ask myself a very simple question – why on earth no profit-hungry Capitalist ever tried to market such incredibly useful products? There are no dearth of such men and women in this wretched capitalist system, are there? Yes, Big Energy might persecute him, but that they would do only after he manages to sell at least a thousand such generators – my common sense tells me as much.

5.    Inventors typically seen in videos are quite well-to-do men of above-50 who have a lot of space (garages, backyards, basement) in their respective houses to do experiments with high-voltage equipment and heavy machinery.  Besides, they seem to have loads of money to spend on projects that may not ultimately yield anything.  They are just men of science trying to satisfy some very noble curiosity of theirs.  That’s all very fine – these are the kind of invaluable men who gave us most of our ‘modern’ technologies.  But when we try to replace the ‘grid’ system altogether, any claim to usefulness of a product must be backed by the economic viability of that product in comparison to existing utility costs.  Nobody seems to be doing that calculation.  If a ZPE machine needs Rs. 100,000 (Indian currency is Rs.) to build and if my monthly average power bill  is Rs. 500,  then why would I buy that m/c ?  It is equivalent to more than 16 years of electricity bill!  And as a Mechanical Engineer who builds things, I know that Rs. 100,000 is not a lot of money at all when you look at the machinery that Mr. Bedini and others build.  Steel structures, motors, permanent magnets, bearings, flywheel, coils, electrical gears, electronic items  etc  cost serious money! And the production of these components and  items itself needs huge factories  consuming hundreds of Megawatts of electricity (for example – steel plants, mines, mineral processing etc.)!
Please understand that I’m no sceptic – I desperately want ZPE to challenge the monopoly  of profiteering Oil & Energy Corporations.   But we must begin the fight in our own backyard, and then we must empower the majority of this world first – the poor and underprivileged.

Very valuable comments and questions. I can only note one fact : if somebody could make Ou device generating just 250W then what is the reason not to do one producing 1kW, 10kW and more ? Obviously the only reason is the cost of material and work. We are living in very unpleasant world when there is something in production available to many people and something that you can do only yourself alone or with the help of friends OR if you have a lot of money - that makes researching new products a pain in... for poor people - yet we, the people need change the most. As you said , if somebody have enough money to pay for electricity whole life without even noticing it, he would not search in scrap yards to collect parts to build any Ou device.
Sorry, for my simple english.
There is other possibility, crazy from the first grasp...somebody is trying to hide the truth which is much bigger then just one or two OU devices...The truth that set us free...
