4 Mhz Solid State Radiant Battery Charger

@callanan
Does the running battery receive any charge back with this coils?

PS
Also I made the circuit as the second circuit post and when I tried to connect a small motor in place of the charging battery it did not work. When I removed the 10uh to ground, then the motor began to spin.

@calanan
instead of neon you can use also an Voltmeter in the testcircuits.
i done 50 years ago an diode to the input plug that bo in te meter
(2 or 20volt range).
So i i tested only co comes in bear from ansmall transitter, i can
see the rectified DC on meter. if i tuch with ONE cable on Oszillator
stage  i ca see any small workink of it.

But all this will not help you - to becomes more out - as the suply deliver.

(I done this with analog meters, (an Germaniumdiode 1N34 1N60 OA90 enz)

Cants say , if Digitalmeters will workk in same configation fine)

ALL,

Please take note of the coils position in Ossie's pix, this will provide some coupling and will impact the operation of the circuit.

Ossie, can you edit the pix and indicate which coil is which relative to the schematic? I feel this will assist those in replicating your design and to get the same results. Just trying to be supportive.

Yes, and probably the winding sense of the coils normally also counts for an oscillator, so it would help also to place a dot for each coil starting wire connection.  Or is it not important in this case I wonder?

Thanks,  Gyula

Ossie my friend ,

very happy to see you ... it's been a while

I can see this is a HOT topic and I thank you for the bottom of my heart for the effort to start it and mostly to continue it with your new proposed circuit.

I'm away from home till Nov. 27th so I can't do a replication now but I will once I return.

Thanks for sharing mate
