Here's an mp3 of a short drum solo recorded with this mic. The mic is positioned about six feet high and two feet away from the drum set. |
Here's a parts list for the electronic parts you'll need for this mic with (excluding the circuit board and the DIN connectors) along with their digi-key part numbers. Digi-key is the only place I know of to order the mic capsules, so you might as well get the other stuff there too. |

You can get the circuit board and the connectors of your choice at Radio Shack. (The circuit boards are probably in the back room.) |
The circuit is constructed on a Radio Shack Multipurpose PC Board (Cat # 276-150) which has been modified by snapping off about 1/2" of its length to provide clearance for the two DIN sockets. I used 5 pin DIN connectors for both the mic head and output connections, but it might be a good idea to use a 6 pin connector for the output to prevent misconnection. Pieces of a plastic binder separator sheet are glued to the top and bottom of the Altoid box to prevent shorts. |

For details on modifying the capsules and constructing the mic mount, please see the modification and mounting page. |
A simple breakout box is used to interface the mic output to two XLR plugs. |
