Introduction

This project results in a cool little battery powered amplifier you can use to show your friends what your project sounds like and you won't even need an outlet. Since it runs on one 9V battery it's perfect for the coffee shop, lunch room, picnics, company picnics (an entirely different affair), scenic outings, other outings, mountain climbing expeditions, sky-diving, quiet sound-ins, quiet rap battles, moon landings and many other situations that I can't think of right now but I hope you do.

I do not recommend the amplifier for: large public address systems, stadium concerts, loud rap battles, booming bass, protest marches, quiet mountain climbing expeditions, quiet picnics, quiet scenic outings. Do not use the amplifier in the confessional, at solemn religious observances, at the library, during church, at meetings concerning announcements about the findings of the LHC at CERN, or at sensitivity sessions where everyone is being quiet. If the sensitivity session gets out of hand you may need to somehow calm the group with the amp and your synth... but I have no ideas about how that might go.
