Hi There!
I've been trying to reverse-engineer a Kill-A-Watt meter latly and It seems like They have this great power supply made up by a simple capacitor and some other basic components:

This is really genious, because for alot of projects like home automation controls and such don't require alot of power, but needs to be compact so it can be embedded (almost) everywhere! This regulator Is really efficient too!
I would really like to make this myself, but I don't trust my Knowledge about analog circutry combind with High voltages...
And if you guys decide to make it, be sure to make one compatible of the 230v mains we have here in Europe
