Transformerless Power Supply Circuit

I have built my first transformerless power supply. It has a zener regulated output of 18 volts and provides around 0.035 amps at 11.5 volts ish.
Although these circuits are directly linked to the mains and are very dangerous they are popular in Christmas tree light sets. Ho Ho Ho!
