Lasersaber strikes again. A joule thief king ?

Very well done Lasersaber !

You are just using a 10.000 uF cap charged up to 12 Volt.

Be sure to comapre the run times also without the scope, cause I had seen
in my old scope some charging up of capacitors with special circuits... but you said,
you tried it also in your car during driving to work...

Well would be very good, if you could make another video and show us the waveforms
on the different connection points of this circuit.

Also you could try, if substituting the copper foils with just a capacitor between the coils
will also do the same function, or is the copper foils have really a better effect....

I have redrawn your diagram to a normal circuit diagram and it is very unconventional...
You are using the bridge rectifier really in a strange way and how you  drive the basis with it...
Did you find it by pure chance or while doing an error ??

I will post this tommorow, cause I am tired right now..if nobody else has already done it..

Great unique design..
I wonder how good this can be scaled up to get a 6 Watts LED lamp lighting fully bright
with bigger ferrite transformers.

It is an interesting circuit.  I am not quite clear on which leads are soldered to the two shields.  I will have to watch him take the coil apart again.  Some more detail in the schematic would be helpful such as what he is using for his FWB, and how he has the LEDs connected.

As LS has tuned it, the circuit manages to dole out very small energy pulses to the LEDs.  My hat is off to his skillful effort.

Here are Laserhackers drawings.

The rectifier brdige is really genuine connected to this circuit, pretty unlogical,
but wow, it seems to work so good...

New schematic, 3D .stl bobbin and parts links here: http://laserhacker.com/?p=401

A side question, if I may...

Do you use support rafting when 3d printing? It seems that the top of the bobbin may sag without it.
I am simply curious.

It's not possible, given the information and the layout in the video, to rule out "electrosmog", that is, the ambient EM environment, as the source of power for this delicate little oscillator circuit.

I agree, and I've pointed that out to him on YT. Still, even if it turns out to be an electrosmog harvester, it appears to be a very good one.
Most attempts I've seen at harvesting environmental electrosmog, usually require a long time to build up any significant stored charge and are quickly depleted under load.

Hi hoptoad,

sorry for off-topic but what happened to your site http://www.totallyamped.net/adams  where you showed the very useful Adams motor experiments?  That site has been down since last July or so and even the wayback machine cannot show the content of the pages...   Perhaps somebody can offer a free site to store all those pages if you have them saved?

Greetings

Hi Gyula, At some stage in the not too distant future (I hope I get the time) I will start up a free hosted site and re post it all there.
The reason the site disappeared is simply because my son chose to go with a whole new service provider for his business. The pages I had previously listed were on spare space on his business site.

I'm not going to rush it though, as there is some information which needs rewording for clarity.

Cheers
