AC Cap Dropper DC Power Supply

Anyone know of a clever way to regulate other than the typical
brute-force zener clamp?

Power level? Input range?

RL

0.8W, Input is 220VAC/50Hz full-wave-rectified.

I love to cook with wine. Sometimes I even put it in the food.

The capacitor must go between the AC line and input to the bridge. It uses
the reactance of the capacitor as a dropping resistor.
