Here are Laserhackers drawings.

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

Lasersaber is the Joule Thief King.....for now anyway.  He has done some excellent work and has shared information on how to replicate.  I am convinced that the old JT circuit is not done showing us everything that it can do.  I take my hat off to Lasersaber for all of the work he has done with this circuit, and its variations.

Hi,

This is my version of the Lasersaber SJR circuit.

Better use N-Channel mosfet to prevent bad polarity connection. Voltage drop would be insignificant, but the cost of such mosfet will probably be too much for simpler circuits.

If the goal is to get really low voltage operation then a JFET or depletion mode MOSFET will do.  For operation in the 1V range there are lots of logic level gate threshold enhancement MOSFETs and lots of BJTs that will do.

Hi Mark,

Yes, and my little 2SD669A is doing quite well in my circuit. I can run the circuit at voltages down to approx. 0,9 Volt
without any problems. But I need approx. 2,8 Volt input to get full light in the LED bulb. I do not need full LED
brightness when used as a "night light", so two very depleted AA batteries is OK in this circuit. My two series AA
batteries is now down to 1,021 Volt and there is enough light in my LED bulb (12 Volt 0,5 Watt type) to see in
the dark. And, the circuit uses so little current that my drained batteries only drop approx. 0,010 Volt each night.

I'm now working on a recharge system. I'm using 10 IR LEDs is series and 10 of them in parallel to get a small IR
solar charger. My panel will charge one 1,2 Volt 700mA NiCad battery from the SUN during the day, and that charge
is used during the night to get my "night light". Everybody knows that a Infra Red (IR) solar panel don't work, right? :-)

No, I was commenting on the video link. The best way to prevent reverse polarity connection at the input stage of circuit is to use low Rds N-Mosfet. That way it will shut-off in case of wrong connection and pass current in good connection without much voltage drop.Something like mOhm range mosfet with Vds above 25V is good.

You are absolutely right, Infra Red (IR) solar panel don't work,
and it  will not work also when you try something weird, right ?

Hi folks, Hi groundloop, thanks for sharing.
Could you share what kind of current and voltage output you're getting with your infrared led panel in the sun and indoor light, when charging your AA cell, thanks.
Also, what do those infrared leds cost.
peace love light

Hi Marsing,

Any PN material that are exposed to light will generate a voltage (and current).
This is also true for IR LEDs that have a clear plastic case. I have tested the
LED panel in total darkness. No output voltage. Then switch on a 940nM IR
light, and voila, the panel has output voltage. It is not weird at all.

I did design 10 of those IR LED panels back in 2007. Was planning to use
them as IR light for a CCD camera. But now you can buy IR flood lights
for that usage that are water proof.

You can probably buy 1000 of those 3mm IR LEDs today, at around US 60$ on the net.

SkyWatcher,

The output voltage in indoor light is approx. 2,8 Volt. The current is very low, typical some few uA.
You can probably find somewhere to buy those LEDs on the net. See above post.

Thanks, Chet.  Good work, Slider.  I like the test where you put the device inside a u-wave oven and it still runs, while a radio won't run inside.  But would like to know how LONG it runs inside versus outside.  IOW, does putting in the cage make any difference?  wasn't clear to me...

Hi groundloop, actually i think about your name. LoL
 
Yes Transistor 2N3055 will do too,  this  from youtube ( i am  not sure about output).

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?
