Take one of these,

One of these:

Mount them to one of these:

Presto! DYI rectifier/regulator.
Or just buy one already made, but where's the fun in that?

Isn't this required for the dynamo version? In which case the rectifier and zener are no use.

Podtronics dynamo regulator is on the link below. If it doesn't work, paste it into your browser.

Yes,the rectification process is to be used for the AC (alternator)systems. The DC (dynamo) needs to have a cutout to keep the battery voltage from backfeeding into the dynamo when the dynamo is at rest,and a regulator,to keep the voltage feeding the curcuitry and into the battery at the proper level.
