Summary

ParaMike, a functional and printable, parabolic microphone for kids and geeks.

Instructions

The given STL files contain a very small, 125mm diameter parabolic mirror.
It can be scaled (up) to any size.
The handle, however, should not be scaled (unless you you know what you are doing)

Except for the "overview file", all parts inside the STL files are
centered and directly printable.

Electronics can be found here: http://www.askrprojects.net/hardware/paramike/index.html
