Frank Piesik – pMic: 3D Printed Microphone #3DxMusic #3DThursday #3DPrinting

Today on our weekly live 3D Hangouts, we will be sharing a short “Field Guide” to celebrate the many ways that desktop 3D printing has entered into the area of music today. Here’s a quick roundup of a few other #3DxMusic projects that caught our interest to whet your appetite!

Frank Piesik – pMic: 3D Printed Microphone:

A printable A-B-Stereo Microphone. I wanted to have a mic which I cought use for general purpose recording in conjunction with my old iriver h120 (with rockbox installed). I didn’t found a suitable mic without a build in recorder:)

So after a little bit googleing I found this article about a low-cost homebrew solution and decided to get a bunch of these panasonic wm61-capsules described in the article to start experimenting with them – here is the result.

A special feature of this microphone is it’s variable stereo width (by time-of-arrival stereophony).

The button near the audio jack is the on/off-swiitch, the second one a gain boost. By swapping two resistors in the circuit, the gain boost could be easily converted to a gain damp. The preamp circuit isn’t necessary at all, if your recorders preamp has phantom power. But the 9v battery increases the headroom for louder signals and powers the 4 capsules more convenient. The distance between capsules and preamp shouldn’t boo to long.

I’m quite happy with the sound. You can download some audio examples here.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! We also offer the LulzBot TAZ – Open source 3D Printer and the Printrbot Simple Metal 3D Printer in our store. If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
