Electron Reversing Device

Here is the schematic for the latest mod.As you can see now,the circuit is very simple.
I have included my latest test results on the schematic.
Now as simple as it may be,i cant see why meters 3&4 read higher than meter's 1&2.

My only thought is that part of the circuit (marked in green box)is a current trap?
I do have a theroy as to what is happening here,but i will await your thoughts first,as there may be a simple explination im just no seeing.

I would also like to know how to lift the frequency up on the SG.Is it a simple matter of reducing the .01 cap?
The reason is that the current in starts to drop rapidly toward the high end of the frequency,and the current at the led's go's up.But i have reached the limit of frequency,so i need to get it higher.

Yes, by lowering the value of the 0.01 uF cap (10 nF nominal, mine was 11 nF) you will raise the frequency. By going from about 11 nF down to 7 nF I've raised up to about 35 kHz (this is at the lowest resistance setting of the Freq pot). But your low end will rise too. The good news (?) is that the waveform is more symmetrical in voltage and duty cycle at the higher frequencies.
I'm now using a 50k, 10 turn pot instead of the 500k.  With 50k and 7 nF my low end is about 1400 Hz and my high end is about 35 kHz.

Also, there's no need to upload an image file to a filesite if you have it locally on your computer, you can just include it as an attachment to your post and it will appear inline. Like this:

While we're at it, here is the FG schematic.

tinman,

So you're back to the meters, ok.

Why did you move the coil connection? Does it not produce similar results with it connected to the high side above m4?

ETA: I'd be curious also if you could replace the two LEDs with diodes and achieve the same effect. In addition, will any other "standard" air-core coil produce a similar result?

Hi Poynt99

I tried all three location's.
Keeping one leg of the coil on ground,and placing one leg on the common rail of m3 and m4-i gain about 6ma on both meter's.
If i place the leg between m3 and the LED,it kills all output and the input meters go high(a short)
But when i place the coil between m4 and the LED i gain about 15ma on each meter?
As the meter shunts are only 1.5 ohm's on the ma setting,i am at a loss as to why i get such a big difference.
I also cant work out why m3 and m4 dont read the same as m1 and m2?

As you would have seen in my last video,there is a carry over of current on the high side into the low side pulse(the probe and ground were the wrong way around when i did the test)

Now i did concider that i have m3 and m4 hooked in series,and we are seeing a double of the current we actualy have.
But three things tell me this cant be.
1-the diode's-being the LED's
2-both positive lead's of the DMM's are hooked together,but one show's a negative current and one a positive current.
So one must be reading the high side and one the low side.
3-if they were in series,then we would see 0 current flow,as they would be reading both the high side and low side-as we seen on  the input side when we first started testing.

So i have just plain run out of answer's

Oh and thanks for the tip on the pic's TK
