TROS - "bemf"

Have changed schematic of "TROS amplifier"; so now both coils are oscillating to capacitor from their bemfs.
Trying to scale it up to make a proper measurements...

why don't you show power input in both system?

@alocinitrebla

cuz it's not OU....

cheers

I'm learning from this circiut, but I cannot see the capacitor's value.

Can you post here the value? Than you so much.

[Mopozco]

thks, MrMagAmp

it's not important, just try any

Please measure and post the current at the input battery when powering your TROS (with and without the 3 bulbs connected to output)

What is the rating of the bulbs, 2 volt and how many mA / watt?

Thanks

@TheGuru2You

I wiil; now I'm trying to scale it up, unsuccessful so far...

cheers

Try to charge 3 AA battery from the capacitor through the diode bridge.

Hi,

great results,

but what is the input current in both modes ?

Can you please show scope shots on a 1 or 10 Ohm shunt resistor ?

Many thanks.

Regards, Stefan.

thks, harpbloke

yes, trying to simplify tests as possible; even eliminated diodes in order to figure out "why"...

[harpbloke]

great results. very clear, and such an easy circuit.

thanks for showing this.
