I am working through this book Make:Electronics by Charles Platt and have come to a circuit that I am unable to duplicate the results of.
Here is a link to the circuit.

I have built the circuit as is but my LED doesn't blink it simply remains lit. My understanding is that the 2.2uF capacitor is supposed to cause the oscillation. However, I can remove the capacitor and the LED remains on.
I am beginning to wonder if there is an error in the book (however I am expecting that I am the one that is in error ) which is why I am posting this here to get all of your opinions.
Thanks
