Mr.Long Man,not made in China..

I finally finished another noise-maker,Mr.Long-Man(Not made in China).Although I was wondering if I should add a moustache and ponytail .I used a very simple circuit for this:
But instead of 9 Volt,I used a 3V coin cell,a 150K resistor instead of the 100K one,and a 1000 uF capacitor instead of the 100 uF one.
This circuit is from the book 200 transistor circuits by Colin Mitchell and can be found here.
