Fading Christmas Lights by Bart Trepak
--------------------------------------

EPE Online, December 1998

NOTE THAT THIS PROJECT IS ONLY INTENDED FOR USE WITH A 
220-240V 50HZ MAINS POWER SUPPLY.

This neat constructional project uses a PIC16C54 to provide
sophisticated 'fading' for your christmas-tree lights. It
could also be used for exhibition work, parties, discos -
anywhere that needs a gradually fading/ blending light show.

Mains operated, transformerless supply, with suppressed 
three-channel triac outputs.


A PCB carries most of the mains interwiring and helps ensure
safe assembly. However the constructional article contains
essential safety advice which must be adhered to.
