How to Build the CMoy Pocket Amplifier

Posted August 19, 2017 by Chris

"I think that the CMoy pocket amplifier is an ideal project to get started in audio DIY. This article is written for the beginner DIYer, though if you just want a guide to building this particular amp, you can skip to the parts or assembly sections.quot;

Developing an IR Remote and Software Controller

Posted May 11, 2016 by Chris

"This one is an interesting one, it’s something we’ve been looking at for a while and figuring out how to solve it. We have sets of speakers and projectors and the users keep losing the remotes, or misplaced/stolen. Usually this wouldn’t be a problem, we’ll just contact the supplier or manufacturer and order replacements. Except we can’t any more."

1WAMP Open Hardware Guitar Amplifier

Posted April 12, 2016 by Chris

"1Wamp is a one Watt small guitar amplifier based on a JFET guitar pre-amp, the Big Muff Pi tone control and the LM386 power amplifier. This portable amp is an open hardware project designed by ElectroSmash using only free and open-source tools."

Happy Days or Staging Beckett with 11 motors

Posted March 7, 2016 by Chris

"Happy Days is exploring narrative in the form of an installation. It is staged without human actors or conventional (verbal) dialogue in a non-theatrical space. We chose to stage Samuel Beckett’s Happy Days since, as performing a ritual in the play, overshadows the performer, the object of the ritual can survive on its own."

Polyphonic FM Synthesizer with STM32F031

Posted February 17, 2016 by Chris

"I’ve built a playable, MIDI capable, polyphonic FM synthesizer using an 32bit ARM Cortex M0 microcontroller and an audio codec. This was a learning experience for me. You can find the finished form of the system in following two images."

Capacitive Touch Piano

Posted February 15, 2016 by Chris

"Our project designs a touch piano with 3 octaves (37 keys) by connecting a handmade piano-like touch-sensitive keyboard with a PIC32 microcontroller. The sound is generated by using Karplus-Strong algorithm with debounce function and with a sensitive reaction time of several hundred microseconds."

OSC and MIDI Foot Controllers

Posted December 10, 2015 by Chris

"The goal of this project is to provide open hardware design of OSC (Open Sound Control) and MIDI foot controllers, primarily targeted for use with SooperLooper, distributed under the GNU General Public License."

FPGA Audio Peak Level and Correlation Meter

Posted November 23, 2015 by Chris

"I started this project more to gather some experience with FPGAs, rather than to design or own such a device, but it ultimately developed into a complete design, consisting of several boards."

Digitally Recordable User Modifiable Sound Emitting Tool

Posted November 19, 2015 by Chris

"A modular electronic drum kit that allows recorded samples to be used as drum sounds. We decided to build a modular electronic drum kit because we thought it would be an interesting project to be able to record ourselves and use our own voices or sounds as drum noises."

DIY Cinder Speakers

Posted November 11, 2015 by Chris

"Daniel Ballou and Dashdot are developing a system that transforms the humble cinder block into a high fidelity speaker. Concrete is a low resonance material that minimizes vibrations and reduces coloration of pure sound delivered by the drivers. A drawback of course is that it’s heavy to handle and ship, and labor intensive to mold."
