Amplifier in an altoids tin.
My friend Allen was the brains behind this. We used this schematic and he added in an LED and a rheostat to control gain.
Because it has a magnet in it, the speaker conveniently sticks to the altoids tin while still being detachable. The indicator LED is inside (the red dot on the right).
The volume and gain controls do not exactly work. In the case of the volume, it is probably because volume is logarithmic, and we should have used a special logarithmic potentiometer.
In other news, I started playing Mass Effect. If Asher lived any closer, or if I had my own Xbox, I would not do any work ever again. Though it isn't like I do any work anyways. Recently I spend my free time doing electronics projects and reading Watchmen. Additionally, I haven't done laundry in two weeks. As we speak, my plans to do it today before Dani visits have been replaced by plans to work on the Arduino board project with Asher. Oh well. College.
