Heya!~ I'm working on my own binaural tube. I saw how much the 3Dio cost($720 USD equivalent in Japan!) and I knew that I could build it for much cheaper. I have about $60 USD of parts for each microphone pair. I have spent much more than that due to having to buy duplicate parts to build with, but that is how it goes.
2x Primo EM272
2x Neutrik XLR Jacks
2x Human Ears
3D Printed Enclosure - The purple prints are the second revision. It has nearly everything correct except for PCB mounting holes. It is designed to print with minimal support and keep all the mating surfaces smooth.
A bunch of mounting hardware. I can't get 1/4" square nuts in Japan so I will have to fix the enclosure design to use hex nuts instead.
Circuit design credit: Grégoire Lauvin / Locus Sonus - I remade the PCB design with their open source circuit to support two capsules and have mounting holes. I will keep all the resistor and capacitor values the same for now. In the future I would like to update the circuit design with an equalizer circuit to make adjustments.
I just got the PCB and all the discrete components in yesterday and today. I will build it soon!~
