Emitter, Base, Collector, Dbl checked!
You have a PNP transistor?Done! I have a VERY DIM LED lit that doesn't do anything when the button is pressed. =(
2N3904You have a PNP transistor?
It looks like the black wire behind the PNP collector is going to ground.One side of the button should go to ground (missing). Besides, pin 6&7 of 555 shouldn't go to Vcc .

That is a npn. The 2N3906 is PNP2N3904
@#$%!!!!!That is a npn. The 2N3906 is PNP
Buy the 50 pack NPN/PNP variety pack if it us still available for about $3 or 5.If you'll all excuse me for 40 minutes... I have to go to Radio Shack.
The circuit works for me, I just set it up.Swapped the transistor, no dice.
