I’ve been gradually working on a bluetooth version of my 3D printed headphone design. This first iteration is pretty much just an experiment in integrating all the elements required for bluetooth (battery, battery charging system, wiring through the headband, bluetooth receiver etc) rather than a polished design. It still needs plenty of tweaking.
It uses the following components:
- 5W+5W amp with bluetooth – way too powerful, but was the easiest option to integrate
- Nokia BL-5C battery – seems to give tons of battery life
- Micro USB battery charge control board (a separate Micro USB socket was used so that the charge port could be located on the bottom)
The controls are on/off switch and volume up/down. I’m planning on putting next/prev track in future versions.
Here are some pics:
I’m currently working on a version that uses a CSR8645 module mounted onto a homemade breakout board…
