Here something different that I built for my studio. It's a stereo microphone inside a dummy head, inspired by Neumann's Binary Head mic, but built at a super-low cost. I put the electronics necessary to drive the microphones inside an external box after a schematic by Elliot Sound Products.
Below is a soundclip I recorded, some drumming on my crappy out of tune drumset with broken cymbals that I have standing at home. I will do a proper recording in the studio some time in the future.
