An idea for the festival season. This basic circuit can be easily modified for 120v operation and more LEDs can be added as well.



Please use extreme caution while handling this circuit since the mains is not isolated and so there is a risk of heavy electric shock.

      By reducing the R2 resistor value more LED's can be added.
