Audio Fun with Inductor Coils

As Ethan and I await the arrival of components necessary to embark on our spring reverberation tests, we pass the time by winding inductor coils and playing with magnetic fields. Read the rest of this entry »

Fun with the Wien Bridge Oscillator

diode_wien_1

Look ma, a (almost) sine tone!

To the fledgling electronics enthusiast who has just enough knowledge of electronic music theory to be dangerous, it makes sense that the simplest tone, the sine tone, should be the simplest/easiest to construct in the analog electronics domain.  Of course, this is not the case.  While geometrically simple to describe, the sine tone is not easily achieved using electronic components.  Most designs found online indicate that the most common method is to “filter” a square wave created by an op-amp through a given set of components placed between the output, the non-inverting input, and the ground.  This is the method employed by the Wien Bridge Oscillator.

DIY Workshop Madness

IMG_20140821_110212

I am really excited to be teaching a series of open source software and hardware workshops this year at Yale as part of a new initiative we started called the Open Music Initiative.  The aim of the initiative is to indoctrinat… er, expose faculty and students to the merits of FLOSS and open source hardware via workshops wherein attendees will get hands-on experience working with, and more importantly making music with open source technologies.  Additionally, it is my hope that the initiative will eventually become a self-sustaining endeavor largely operated and promulgated by members of the Yale community.

Modular Synth Components

Last night El MuCo (The Mutagenic Cooptoraptors) accomplished a feat heretofore unimaginable: three circuit projects were undertaken and three projects were completed successfully.  While you may be tempted to think that, with the assistance of a book (Ray Wilson’s Analog Synthesizers) and the vast power of the internet this is not a big deal, you could not be more mistaken. Not only because of our chronic electronic ineptitude, but because even getting all the parts together for this much electronic awesome is daunting.  Of course, we didn’t have all the right parts, but we did it anyway because SCOFFING AT CONVENTION IS OUR BREAD AND JAM™!

Experimental Musical Instrument Workshop @MakeHaven

Contact Mics hanging up to dry following workshop 1

Contact Mics hanging up to dry following workshop 1

Yesterday was the 2nd of what will now be three workshops I’m giving at MakeHaven hacker space in New Haven, CT. The first two focused on creating contact mics and designing and building acoustic instruments. The third workshop, TBA sometime in October, will center on basics of electronics and circuits, bending/hacking instruments, toys, household objects, etc, and then interfacing the analog with the digital via Arduino. If you are interested in coming to the third workshop, please leave a comment below, or go to http://www.makehaven.org to check out the event. (You do not need to have attended parts 1 and 2 to attend part 3.)

You can see some pictures and videos from the workshops at the following link:

Batch Normalize and add Fades to Audio Files

norm_fade

A new project I have just started has had me editing a lot of relatively long audio files.  I have to cut them up separating the noise from the spoken word, normalize each file, and add fades to the beginning and end.  Then, I have to export them.  I was using Audacity, which is a great (though ugly) audio editor.  However, there are some problems with batch work in Audacity that ended cost me a lot of time and ultimately making it unsuitable for my purposes.  Finding no app for mac to quickly batch normalize, add fades, and save as a 48k/24-bit file, I decided I would bite the bullet and try to *assemble a bash script to do the tedious work for me.

INI Workshop Prototype Instruments pt. 2

INI Prototype Instruments Pt. 2

INI Prototype Instruments Pt. 2

These are the last of the prototype instruments I designed for the INI instrument workshop which took place last Thursday at Artspace New Haven.  If you go to ininewhaven.com you can see some pictures and video from the event.  Turnout was great and everyone had a swell time making things to make noise.  We plan to give a series of instrument making workshops at MakeHaven (makehaven.org) in the new year so stay tuned.  We envision a 2-part workshop where we would make contact mics in part 1 and then make instruments in part 2.

How to: Make Contact Mics

OLYMPUS DIGITAL CAMERA

In preparation for our instrument making workshop at Artspace New Haven on December 13th, your intrepid guides Brian and Scott spent a foggy Sunday afternoon making contact mics from scratch.  The below is both a how-to and an advertisement for the workshop.  If you are around New Haven, please follow this link to the INI site and register now as seats are limited to 10 and they will go fast.  So without further ado, lets make some contact mics!

INI Workshop prototype instruments Pt. 1

LLW in Action 1

In preparation for our workshop at Artspace, Brian and I met to quickly put together a few prototype instruments out of wood, screws, springs, etc.  We basically wanted to see what we could do with next to no materials (and no preparation.)  The following prototypes are the results of this first meeting.

El MuCo at ArtSpace: Instructions not Included

Brian and I have five of our hand-made musical instruments in the gallery at ArtSpace New Haven as part of an exhibition titled “Instructions not Included.” The exhibition will run from November 9 2012 – January 26 2013. The opening is tomorrow from 5-8pm at ArtSpace. Please feel free to join us and explore the exhibition which has some really great work.

Here are some pictures of our contribution to the show.
