Make a deadly LED toadstool lamp.

A full guide to making your very own electrical deathtrap floral display with dangerously live interchangeable LEDs.
This project is completely unsafe, and should not be built by anyone with an ounce of common sense.
The circuitry is based on a simple capacitive voltage dropper (hence it's inherent shock hazard) which allows the power supply circuitry to be fitted into a very small area and gives very high efficiency of around just quarter of a watt power consumption.
The LEDs are in standard Molex style 0.1" (tenth-inch / 2.54mm) pitch sockets which have wire stems that are looped so that all the LEDs are in series like standard Christmas light strings (fairy lights).
The power supply and base of the stems are potted into a suitable lamp holder with resin and in this case I also added a few stems of plastic lotus leaves from an existing Chinese LED night light. I also used some of the night lights silicone mushroom shaped LED caps on some of the LEDs.
Once again, this decorative device operates at mains voltage and contact with the pins of the LEDs could give an electric shock. As such, if you build it, then you should turn the power off while changing LEDs and also make sure that the light is never put where a child or any "normal" person could handle it while lit.
