Portable Speaker Sphere

A portable, battery powered audio speaker.


it's a sphere width a diameter of 120mm. Inside is a 1500mAh Li-ion battery and a 2x3W stereo PWM amplifier.


This was just a quick project for me, with existing parts, so I can't share a build guide. but if you have questions, feel free to ask.
