IC1 is a CMOS 555-type timer
IC2 is an LM324 or similar
IC3 is a TDA7052 audio amp
Q1 is an N-channel MOSFET, IRF510 or similar
Q2 is an NPN Darlington, TIP120 or similar

If you make any substitutions, it is assumed that you can understand schematics well enough to make them intelligently. Do not use a bipolar 555 to replace IC1. The 7.5 V Zener is used here as a noise source, and the 470 pF cap rolls off the response to make the white noise pink, and the value is somewhat dependant on personal taste. The 2 LEDs are surface mount devices, glued onto the front of a pair of sunglasses.
