As I understand the process the ampage is the critical factor that drives the plating process, hence the 100 mAmps per square inch. The power box I borrowed allowed me to set ampage and the box adjusted the voltage, I often had nearly 0.5V showing so a measurement of the amp draw is essential.
Is it possible to rig up some kind of cheap and cheerful digital current controller if using a 12v battery charger as the power source?It would have to be simple for those of us with minimal elecrickery skills or knowledge. 🙂The simple filament wire controller included with the kit is very hit and miss.

Apologies for Hijacking your thread Ted.AshThe circuit appears to be a constant current control circuit irrespective of input voltage.If I want to make this a variable current controller is it simply a matter of installing a potentiometer in the output side of the circuit as a variable resistor?Cheers Ian
