Feedback To Source

@all

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.

Thank you @jadaro !

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.
