I wanted a super small amplifier circuit that would fit a 2450 coin cell. It was based on this circuit here: http://fritzing.org/projects/single-transistor-15-db-audio-amplifier

I have no idea whether this would work, this is my idea for an amp and i really hope someone would help me correct it / improve it.

Hi, Try to make the schematic view of your project. You will see that it does not correspond to the schematic of your link. The only thing it will do is to switch-on the LED.
