How to Make DIY Magnetic Wide Stereo Contact Microphones That are Basically Indestructible + Demos
I originally intended to sell these, but after testing that, I couldn't make the math work - never seemed worth it given the effort and the price point needed.
So I instead created this video to explain how to make them, for those who want this kind of thing.
Materials Needed:
3D printed parts:
