You’ll find no shortage of Altoid tin projects (and certainly no shortage of Altoid amps), but this compact design functions as both a well-designed speaker and guitar amp.

Dino Segovis, the guy behind Hack-A-Week TV, shares an awesome video on how to build an Arduino-based 1/2 watt amplifier that amplifies both your speakers and your guitar (with neat distortion effects). Check out the video above to see him explain the circuit, build one, and the demo it.
