Bluetooth speaker tube for Kebidu Radio/Bluetooth/MP3 module
thingiverse
This is a straightforward modification of the original Bluetooth speaker tube designed to fit the Kebidu Radio/Bluetooth/MP3 module. Since the module's output is not amplified, I created a simple stereo amplifier that fits inside the tube. The power supply comes from two 18650 Li-ion batteries connected in series (delivering approximately 8 V), which are required for powering the Kebidu module.
