Hi Btaylor,
It is not actually a pure DC rather it is halfwave or fullwave rectification and no large caps to mentain it ripples or wave on its output so falling of waveform with the 60Hz freq will be available at the output...

Hi,
What voltage is the rectified wave form? If it is highish voltage it is easy to connect this straight into a pic, through large value resistors. This is how you detect the zero point of the waveform.
It is NOT a good idea to rectify mains, some sort of transformer must really be used, for safety.
Regards Bob...
