Introducing Simple Amp!
This simple yet powerful audio amplifier is an ideal DIY electronics project. Using a minimum of four parts you can build an amplifier that will put commercial sound systems to shame. Not only is this amp powerful, but it is compact, able to fit in an Altoids tin with room to spare! Check out these instructions on how to build your own.
This is the same amplifier circuit that is used to power the large 8 ohm speaker in Salvius's head. It was very important for this project to have a speaker capable of being heard across a room with clarity. Salvius is designed to be able to interact with people and the quality of sound for the robot's speech plays an important role in the ability to do so.
