Building microphones is fun and seems to be of interest to readers, so here’s a collection post for posts about that! These posts discuss building both microphones, and, when applicable, their matching microphone driver circuits and/or pre-amplifiers.

Building a Carbon Microphone:

• A Microphone of Constant Sorrow, Part I – I just wanna be able to sing into a can, just like them fellers down at the radio station (19 May 2016)
• A Waveform Sung Into a Can, Part II – test of a driver circuit: version 2 (v. 1 didn’t work – 20 May 2016)
• Building the “Can,” or the a carbon element mount, Part III – wherein I build a shielded containing structure for the carbon pickup element. (23 May 2016)
• Once Upon a Time in a Catalogue, or A Microphone of Constant Sorrow, Part IV – putting the driver circuit into a case, as well as additions to that circuit, and the interface design (25 May 2016)
• Not Just a Display Piece, Part V: a final photo and ideas for use (27 May 2016)
