Here's the value I originally had: R2 and R3 were 500k potentiometer, R1 was a 470k (I think), the capacitor was a 10 micro farad electrolyte capacitor and finally the 555 chip. As for the wiring, from what I remember, pin 1 to ground, pin 2 to capacitor to ground and to pin 6, pin 3 to R1 to LED to ground, pin 4 to power, pin 5 nothing, pin 6 to R2 to pin 7, pin 7 to R3 to power and pin 8 to power.

Cheers
