Marsing,

I was a member of a Radio Control flying club when I first did choose my Internet name.
We did a lot of groundloops back then. :-) Also, I have seen a lot of groundloops when
designing audio amplifiers and such. :-)

Yes, if you cut the top of a TO-3 transistor (or diode) then you can use the die as a NP solar collector.

One thing I was wondering about is why the designers of solar panels do not combine those
panels to also heat water. And, the panels should have a Fresnel lens on top so that the orientation
of the panels does not matter that much. So, three layers, first the Fresnel lens layer, then the NP layer
and last the water layer. Or does that already exist?

GL.
There are integrated PV / solar heating systems available from a number of manufacturers.  It is not all that cost or area effective as you might think. It adds complexity and safety issues of bringing the coolant into close proximity of the PV electrical.

I tried to replicate Lasersaber's SJRLooper but had little success.

Then I saw the video from Igor Moroz https://www.youtube.com/watch?v=P0kVuhWJwCY and this worked for me.

My transformer has three layers (no copper foil), first layer 29 turns, the a layer with 5 x 29 turns and finally a top layer with 26 turns, wire YT 0,6 mm.

I see a little feed back, but I have to try with a different transformer and a few LEDs (instead of the 220 V LED-Lamp).

I think that the diode in the feed back loop is not necessary because the battery withh absorb the negative pulse and store the positive pulse.

Greetings, Conrad

Hi folks, Hi conrad, thanks for sharing the information.
Built a 3 coil, like the circuit you posted, still wiring it up for testing.
The ferrite e-core has
bottom coil, 1 layer of 24awg.- 52 turns
middle coil, 5 layers of 24awg.-260 turns
top coil, 1 layer of 24awg.-52 turns
2n3055 transistor.
Still working on it, we'll see how it goes.

peace love light
 :)

I started with implementing the Joule Ringer (the circuit is on the drawing in my last post, just two windings used) and then modified it by doing something with the third winding.

I am working on a coil similar to the coil of Igor Moroz, see the attached drawing.

The goal is to find out which diode (LED, Diode or none) is necessary and helps for feedback. Then the right resistor (R1, R2) values and the number of turns for the windings (w1, w2, w3) have to be determined. There should be at least one LED to have light.

So far I could not see any advantage in the use of a full bridge rectifier. And it has to be tested whether the copper foils on the coil are of any use.

the foils are important, and lasersaber still has them wrong... see 3v akula circuit... which is what it's based on, other than a joule thief to drive it.

Please see the attached drawing. Which one is the right connection of the copper strips? Version B and C are probably the same.

B and C are the same and B and C match this video


just flipped the coils so the dots were all on the same side in B  (made B last... C was a rough sketch)

Hi folks, here is the circuit of my looper variant,
similar to what conrad posted.
It lights the 6 watt led bulb more than adequate
 for a night light and using 3 AA nimh cells for 3.6 volts,
 it gives very usable light at 200 milliamps or 720 milliwatts.
This gp19 ecosmart led bulb is non-modified.
Will be testing next with capacitor on input and see what we can do.

peace love light

@SkyWatcher: nice replication!

If you have time, you could try the changes I have indicated in your drawing. The power consumption should go down considerably. But the LED lamp will be a bit dimmer. (It might not work with 2.4 V, but it worked for me nicely with 3.6 V power supply.)

The 100 Ohm resistor is not very elegant and could be replaced by a better way of driving the transistor (which I have not figured out yet).

The LED from transistor base to negative rail consumes the negative spikes at the base which are not very good for the transistor (but the 1 K resitor at the base of the transistor might be sufficient to prevent damage).

I wanted to go back to a basic Joule Thief but with a third winding for power feed back.

There was little success, it seems that one can not really feed back power. Use of the third winding changes the frequency of the circuit and can reduce power consumption (by up to 20%) because of a lower frequency (less pulses per second --> less power consumption).

See the attached circuit:

When using this low supply Voltage (0.3 to 1.5 Volt) LED2 is not necessary (to protect the transistor) and causes unclean switching. But its light seems to be free. Having the LED2 in place does not change the power consumption.

LED3 could be a diode, but in this circuit a LED reduces power consumption more than a diode (but both reduce the frequency, the LED more so).

Using a full bridge rectifier with winding 3 did not give any positive results, LED3 seems to be enough.

Connecting winding 3 somehow to the base of the transistor (instead of to the negative rail) did not give better results and LED3 will be dimmer.


If there is progress it is NOT a third winding for power feedback. May be copper strips on the coil will help? I will go back to a Joule Ringer type circuit (very many turns for winding 2 in order to have high Voltage e.g. for a 220 V or 110 V LED lamp) and copper strips.

The foils are connected to the 'third winding', not the driving side...

@d3x0r: please see the attached circuit. It is my way of "translating" copper strips to a Joule Ringer. The main argument is that the bigger winding (5.9 mH in the original) has no connection to copper strips. It is the smaller winding (2.6 mH in the original) which is connected to the copper strips.

In a Joule Ringer the smaller winding is driven by the collector of the transistor.

The original has only two windings. (A Joule Ringer also has only two windings.)

If you have a different opinion, I would be interested to hear your reasoning.

OKay well; the joule thief/ringer requires 2 for its own driving purposes... and while you can put a load on that to block enough current to get a higher voltage from the collapsing field; you can get much higher voltages using a (I'd call it) secondary separate from the driving...
The akula project has a single coil, because the driving function is part of the semiconductor part... So to use a joule theif sort of self trigging oscillator you do need an extra winding for the base pickup sensor (thing).


your plan of attack looks good; could work

I'd use another pickup; but then again that coil is the lower inductance side... I think you end up with the foils attached to the W1 ... even though it's isolated with the 100k resitor and... I dunno that might work


well I don't know how you'd loop the energy back that way...


---
but I don't really comprehend how the foils would play a role...
1) they're lowest inductance/highest current... maybe a way of leaking some current into higher voltage?
2) they should be close enough to have a capacitive effect also
3) trying to figure otu the induced current paths... one side or the other ends up opposing that ends 'natural' polarity at that point;  and that means the secondary will be somewhat directional.... like just reversing the leads doesn't reverse the polarity...
