is a transformerless power supply for low current applications. C1 is
the X rated AC capacitor that reduces high volt AC. D1-D4 rectifies AC
to DC and C2 removes ripples. R1 is the bleeder to remove stored current
in AC when power is off. R2 limits inrush current. A Zener can be used
in the output to get regulated DC.

Caution! Circuit is lethal since it carries high volt AC. Do not touch or test when connected to Mains.Enclose in a shock proof case.
