This is my first electronics project. I am trying to do the 555 / 556 Timer IC circuit for a halloween project I want to do, but my LED wont blink.
Here is the tutorial I am trying to follow:

(yes I realize this is a 555 tutorial and I am using a 556 chip...I have got a schematic of both to match the pins)
Here is what my breadboard looks like:
**broken link removed**
The cap is a 6.3v 100uF and the resistors are 12Ohm if I am reading the bands correctly.
Oddly enough if I pull the resistorfrom pin 14 and 1 the LED comes on, but no blink???

Any help is appreciated...
