Jesus:

A little while back, I purchased 50 1N34 germanium diodes for $.19 ea from American Microsemiconductor.  These are listed as germanium diodes and, according to them, not a substitution.

www.americanmicrosemi.com

This suppliers only problem in my mind was the minimum order of like $40.00 which is why I bought about 50 pieces of a bunch of stuff including 2n222s, 3904's, 1N4001s, 1N4007s, and 2N3055s.

I got them for that "energy from the air" concept that I know you said you replicated.  (from that video on youtube)  I have not gotten around to attempting that yet.  Once I get my taxes done, maybe I will have some time to do so.

I hope this helps.

Bill

Thank you @pirate!
Did you checked the number on the diode and it says 1N34? Or just you trusted what they said?
Everytime that I send for 1N34 diodes they send a 1N60 instead. But they put on the invoice 1N34.

Ok, so I checked the evaporating liquid again today and there are hundreds of flat square crystals growing in it along with a green muck and some vaguely iridescent films.  Here's a picture!  ..the square crystals reflect light pretty well...

There is a way to reproduce the crystals you created. I thing they called growing a crystal. There was a member here that used to grow crystals with the shape of a piramid. I forgot where exactly I saw that topic. But I think that making a search for the words "growing crystal" and "crystal piramid" will give you interesting results.

I say that because to use a crystal, I think that it must be big enough. Growing it will accomplish that.

@ Jesus:

No, I did not check the actual numbers on the diodes because......there are NOT any!!!  I just now looked with my reading glasses and there is no number on any of them at all.  So, what you are saying may very well be true....how could I tell?  Yes, it had the correct numbers on the invoice (of course) but.....I did not realize these had no markings on them....heck they could be anything really.  Well, I lean something new every day.  Thanks.  So let me rephrase my earlier post.....I may have bought some germanium diodes.

I dont know but there are some diodes that does not have any numbers printed on them and are belived to be germanium. They are some kind of green and yellow I think.

As a continution of my electronics study, here are the other transistor application circuits that I finish drawing on paint.

I thought that by studying an electronics course, I would find the answer to the feedback problem and now I have more questions than answers.  I am a lot more confused.

@Jesus,

I've done some isolation.

I mixed equal parts of white vinegar and hydrogen peroxide to form peracetic acid, which I've allowed copper to rest in, occasionally stirring.

After a few days this solution turned a deep blue with time, it is increasing to a deeper blue color, at rest, it contains some green tones as well.

I took a bit out and let it evaporate, it has formed these crystals in the bottle cap.  I look forward to testing it's electrical properties.  Per process it should form copper acetate with some intermittent copper carbonate.

It seems that you are getting something new. At least this photo looks a lot better than the other one. Lets see what happens.

I have been trying to understand the @mk1 toroid construction in order to test if it can be used as a feedback to the source somehow.

I finished the graphic with my idea of how to construct or build an @mk1 toroid. I will post it here for reference and I will post it also at @pirate's thread (Jule Thief)

I did the double post double through switch circuit and test it.
The batteries get discharged too quickly.

Although it charges the one that is uncharged, when the switch is flipped to put the other to charge, the one already charged just last a few minutes if not seconds.

Then the one that was the running battery is discharged also.

*****

What I need is the knowledge to build a solid state Double Post Double Through (DPDT) relay, to use it in place of the switch.
Does anybody has a circuit to do that DPDT solid state relay?

Thanks for the PM, I can only send the DPDT transistor setup by posting it here.

I assume you want to switch a Positave and a Negative

Now just before anyone says it's not right, (you may be right) I will do a search on the net about switching the negative rail using discrete transistors, however here is what the circuit should look like.

Ps, the only way to make it work is to use 2 seperate switches, or take a Positave feed via 2 NPNs (further up the line)  to feed either of the necessary transistors.
If using for light current under 1 amp, use BC 548s over this use BD range or the 2N3055's or try MOSFETS, or pick on the Darlingtons.

Welcome @electricme !
Thank you for your prompt response to my question.
The difference is that only the positive is going to be switched.

I made a circuit from my study of logic circuits.  Maybe my logic is not the right one but it is a starting point.

This may or may not be helpful here but, thanks to a suggestion from Wilbyinebriated I made a device that pulses my AA battery that does not use up any power.

http://www.youtube.com/watch?v=XYhNw6SuTfA

I call this the Wilby's Bird experiment.  A joule thief, supercaps and leds being pulsed by Wilby's Bird.  This idea may come in handy for you at some point.

Thank you @pirate !

If that bird were faster you would not need anything else to get that light going.
Very good experiment!

I finished my experiments with the battery switcher. Now I have the resources free to start experimenting on other thing. Now I will start with the resources that are left. I mean that did not get damaged experimenting, to build the transistor battery switcher.

It is expected to use and keep both batteries charged while working without stop.

I will explain the principle behind the logic circuit I presented here.
According to my readings, the joule thief transistor produces two different sparks of energy.
One when it turns on the LED and the other, when it turns off the LED.

With that said.
There are two diodes on the circuit.
 1. After the collector
 2. Before the emitter

The one after the collector is the charging diode. It is activated by the wire before it going to the base of two transistors.
The one before the emitter uses the bemf spark to hopefully activate the second group of transistors that will provide the alternated battery positive to the joule thief coil.

That is it! Hope for the best!
