Bluetooth Speaker

A mobile speaker that connects wirelessly to your smartphone and provides music enjoyment on the go. An USB port lets you charge devices and a built-in lamp provides light in the dark.

The case used to be a cigar box and the back cover the lid of a jewelry box. Other parts came from defective equipment and were thus recycled:

  • Super bright LED: Flashlight
  • Active speaker and self-made passive radiator: PC speaker system
  • USB connector: USB-HUB
  • Lens for displaying charging status: Camcorder

The 2 x 3 watt speakers are driven by an appropriate amplifier and a bluetooth module provides wireless connectivity. An unused 15000mAh powerbank supplies the whole System with power for a sufficiently long time.
