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.
