- If you use the mic, please let me know, I'd love to hear about it! :-)
Assembled OpenBinaural microphone:
The left and right ears, and the potentiometer knob can be 3D-printed in PLA or ABS. Flexible materials may create more realistic effects!
The support for the ears can be laser-cut out of 3mm plywood (DXF file) or 3D printed (STL file).

Where to buy
I currently have no plans to sell this microphone, it has an open license so anyone can build it or sell it (as long as they provide attribution and publish their modifications as open too).
Please refer to the following links if you just need a binaural microphone that works out of the box:
Great inspiration was taken from 3Dio. If you need professional quality & high-performance, check out their Free Space microphones!
The potentiometer knob model is derived from John Ridley's: https://www.youmagine.com/designs/knob-for-potentiometer-parametric
I want to thank Imperial College Advanced Hackspace and Imperial College Robotics Society for providing the infrastructure (tools, 3D printers, laser cutters & material resources) that made this project possible. The community that has grown upon them is just amazing.
Also thanks to Mr Rodrigo García Saura for sourcing the 1/4" to 3/8" convert screw for the tripod mount
