Bluetooth Speaker 5

2021- Work in Progress
Personal project

A portable bluetooth speaker with random 3D geometric wooden face, concrete case, and brass analog knob.

Fifth work of my personal DIY bluetooth speaker series. The emphasis was on :

  1. Analog volume knob with on/off rotary switch.
  2. Bringing out the contrast of materials between concrete enclosure and perforated wooden front panel
  3. Random geometric 3D pattern front panel. 

Still working on the concrete enclosure.
