You may have the wrong mic then. Any specs on it? Some need power to work.
 
have the sch modded like attached. The condenser mic body goes to negative as you know.

Besides the microphone connection the trigger input pin of the timer IC should always "see" a potential.

If you use R1 and D1 as in the attached circuit schematic the circuit should work.

Also 470Ω for a current limiting resistor is a bit high of value making the LED very dim.

Using 220Ω the LED current is around 17mA. At 180Ω the LED will be drawing 20.7mA.

Specs means? It's written with 26S. Is that means specs?

hi,
'specs' is an abbreviation for Specification, the Specification is the performance data for the device, thats printed in the datasheet for the device.
