Complete Astable Multivibrator Circuit Updated

01:00:20

Exp. 11 from Make Electronics 3rd ed. (Fig 11-16).    To start the circuit,  shake briefly to introduce noise. 

The values of the resistors under the 2 LEDs were lowered to 1/10th the value given in the book.  The 8 ohm resister at the bottom R is meant to represent a 8 ohm speaker.

Shake the phone to inject noise. You also need to lower led resistor values.
