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 potentiometer knob model is derived from John Ridley's: If you need professional quality & high-performance, check out their Free Space microphones! Our suppliers have put together microphones listings with all the latest. The awesome ear model was designed by Jonathan March:įor this project, the STL was modified with FreeCAD and Blender Looking for the right wholesale binaural microphone has made it easy. Please refer to the following links if you just need a binaural microphone that works out of the box: 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). The Gerber files, B/W layout in PDF, and CNC gcode files can be found here. The KiCad sources for the electronics can be found in the Electronics folder.
The metal insert can be found in eBay as 1/4" to 3/8" convert screw Electronics The support for the ears can be laser-cut out of 3mm plywood ( DXF file) or 3D printed ( STL file). Flexible materials may create more realistic effects! The left and right ears, and the potentiometer knob can be 3D-printed in PLA or ABS. If you use the mic, please let me know, I'd love to hear about it! :-).
