looks like the green is staying put.

Maybe you discovered a new kind of diode making process.
The thing is that if you let the material aside for a few days and it corrodes, it is no good for an electronic application, but if it does not corrode further, then you got a good homemade diode to use on an electronic circuit.
A crystal radio on this case.
Good luck!

@all

I am on a feedback to the source quest and feel just like a lion on a cold weather and a harsh environment with the problem that every step taken is hard and difficult.

Hi everyone,
I found an interesting video and image variable capacitor.

Thank you @tbest !

That was great! Those two links are fantastic!
Do you know how it is that it can be translated?

Edit:
I made a search for Gollum's Crystal Receiver and found this other good link to share:

I poured the solution I used out into a flat plastic container and let it dry, this thin films continues to form on top of the solution, ..it's blueish green, has different domains of color and ..the corrosion on the copper plates is persistent.

The film seems to be preventing any evaporation from occurring so I assume it's reacting with the air...it's forming whatever formed on the copper after I pulled it out.

I think that if the copper is corroding continually, then that diode cannot be used as a crystal radio diode. Because the corrosion will be passed to the other circuit wires.
But the blueish green color can be used as a color on a painting. The canvas does not corrode as the metal does.

Perhaps the painting could be connected to a wire fence or something and result in a Feedback To Source.

Thank you @tropes !
You are right, maybe it can be used like that.
There is a paint already that does just that.
Maybe @jadaro2600 has invented a new continuity paint.
You never know!

The corrosion is persistent, as in, it's not evaoprating in the air, it's just ..there, and not going anywhere, it's not spreading and it's not leaving.

That liquid must be evaporating and regenerating from the air.  Now that situation makes me remember a movie called the blob. It was some kind of silly putty that was alive and came from space.
There is a new problem then, if that paint like liquid does not dry, it is not possible to use it as paint on a canvas.

You have a very strange liquid there. I recommend that instead of trying to build a diode with expensive acids, you better get the diodes that are already available and use them. The most difficult to get is the germanium (1N34A) but the substitute used (1N60) is available almost everywhere for less than a dollar.

It does not produce much voltage and I have not been able to get sound from my crystal radio with it, but maybe you have better luck with it than I. I only got 0.04v from the environment and no sound whatsoever till now.

I think that the automatic battery switcher even though it is not a feedback to the source, is the best choice at the moment, that is in the meantime we can get a true feedback to the source.

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

I suppose that my tests are on topic after all, I've wanted to make this diode so that I can use it at such low voltages...  I think that I have some diodes which are resulting in diode test of a 0.21v forward voltage.

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...

Jadaro:

Looks like an aerial shot I remember seeing of Chernobyl.

That is fascinating.
