12 v dc dynamo

Except that Uncle Joe Lucas , Prince of Darkness , made millions of the things , and modern , smaller solid state equivalents are also available . So perhaps not so much reinventing the wheel , as using one off the shelf .

I think I would start with the basic unregulated circuit first to see what is attainable.

I would connect terminals F and D together so full potential should be available between terminals F/D and the body of the dynamo. (see circuit post 18)

I think using a variable wire wound resistance might be much the same as controlling the engine speed manually.

I would also check out bulb availability and investigate the dynamo’s output at 6 Volts.

use a bike reg from john goff cant remember his website small solid state and reliable he does ones for dynamos and alternators inc dynamos with no battery
