you can then adjust the main base resistor for different sized batteries. If you get real clever with the chip you could switch different resistors in and out.

To monitor the battery voltage you will need to learn how to use the ADC inputs on the PIC.

Hi John K.,

I have examined the patent and looked at the Fig 4 schematic. What are the component values? Where is the coil that was show in a video Bedini posted in the SG Oscillator thread?

I want to use the SG oscillator to charge the Lead Alum batteries.

Sincerely,
