This “small” box allows wired headphones to receive audio via Bluetooth. A clip lets you attach it to your clothes, so you don’t have to carry a smartphone on your body when you’re working out or deal with a tangled cable when walking down the street.
The following components are installed:
- 5.0 Bluetooth audio receiver module
- Boost converter “MT3608”
- Charge controller “TP4056” for lithium cells
- Switch
- Battery from a disposable e-cigarette (Elf Bar 600)
The 3D printed housing is made from 100% recycled PETG.
