Feedback To Source

[spinner]

@all

My goal here is to run a motor with a 1.5v or 9v battery and charge the battery while running the motor.

The question is:
If I have a circuit, like the camera circuit, that increase the source voltage from 1.5v to 12v, How I can feedback to the source battery without conflict between the two different voltages?

Check out the standard power/energy and U/I concepts...

I will not make you suffer. The circuit is very simple. It runs a newman motor. but the 1.5 battery only last 4 minutes.
Lets see all the brilliant minds that are on this forum at work. I will do my best too.

Thank you jesus

That was the very first time I ever said those words.

I'm 'spiritual'...and a recovering cathoholic.

Seriously though..have you tried attaching your 'jule thief' to the circuit ?

I tried but I burnt the transistor in the process. Did not have a good guide schematic to do it. I know a little about electronics, not much.

That is interesting in itself jesus...I would have thought that the 'j/t' would just simply not have the power.

I'm not sure what it means..I'm sure someone else will know if there is anything significant to that.

Is there a way to do manually what the transistor does electronically...just to see if the 'j/t' will pull the load ?
