Electron Reversing Device

Here is how I modeled an LED.

It worked quite well. It is a switch that changes between 20 Ohms and 1M Ohm based on the voltage across it. It changes through the resistance gradually between the two limits you set, in this case 2-3V as shown.

The circuit is a variation of a JT.

Poynt:

I found a diode with a real part number thanks to your help.  I guess that I was using a "blank" diode.

I adjusted the clock to 10 KHz.

I had to do a new schematic, a quick and dirty Beta Tinman:

And now a Beta Tinman timing diagram.  I focused on looking at currents in this timing diagram.  I added annotations to the timing diagram where current is either flowing "left" or "right" or "up" or "down" relative to the schematic.

Even though the component values are not correct, you still see somewhat of a resemblance to TinMan's clip.  I won't go any further than that!  In my analysis, I got the direction of the current going through the coil backwards.  So my earlier analysis is wrong.  Also the path changes for the inductor current flow, and if any keeners study the timing diagram they should be able to figure it out.  At least I was right in that the current always is flowing in one direction through the coil.

Not surprisingly, I got a lot of surprises when I looked at the results of the simulation.  It just goes to show how hard it is to look at even a simple circuit and figure out what is going on by eyeballing it.  KCL and KVL to the rescue!

tinman,

Can you confirm MH's schematic? Is the coil connected to the resistor-LED junction as shown, or to the "input"?

The schematic is correct other than the two diode's-which need to be LED's.
Although LED's are a diode,they have a completely different effect on a circuit.
A normal diode will not burn off or remove energy as such that an LED dose.

This brings me to some questions i must ask about your sim tests.
If the simulator dosnt have an LED,and you have to make something that simulates an LED-how accurate will it be?
Dose your simulator have a BPC or is it just plain inductors you use?
Dose the simulator take into account the magnetic field that surrounds the earth,and the effect that this may have on the BPC?

Simulators may be great for every day electronic setup testing,but as we are trying to gather extra energy from our surrounding's-like the earths magnetic field,energy from the vacume-all that jazz,then i think the sim should take all this into account if it were to be accurate.

For me to go any further on this setup,i will need to get myself a two channel scope-so as i can see both scope traces on both output resistors at the same time.

I have charted the scope shots as MileHigh said to do,and the outcome is the same.
I also fail to see how the voltage across r1 leveling out very slightly across the second division on the scope,can be equal to the voltage across r3 to go up to the 3rd division on the scope.

But i will say this-i am still learning,and all your information and explination's i do take very seriously.
This is how we learn.But until i understand as to what is actualy happening-i keep on serching.

Cheers
