In the Darkness! Sun 26th April 2015

Have you ever heard the sound of fishing line? Probably not! That’s why we are here. Our purpose is to present to you materials like never before. You can hear the Fishing line as it stretches due to the weight of the hanging blade. The recording was made using our Frame Project. Below is a high fidelity recording of the miraculous phenomenon of elasticity.

The fishing line was directly knotted on the hooked Piezo discs. This knotting technique perhaps facilitated the stretching of the fishing line, allowing us to hear the speaking length of the string between the hooks and the hanging blade.

More Laser Sounds with OptoNoise

Following our last meetup’s indulgence with the sounds of lasers, in this meetup we continue to gaze in awe at the ceiling, as laser beams hits intricately patterned spinning discs, creating a beautiful display of sounding reflections.



Sounds from the OptoNoise project can be heard above in the Soundcloud Playlist.


Behold! A glorified button with a Screen!


More Photographs.

Slinkies: Sun 22nd Feb. 2015

This meetup, we experimented with the sound of Slinkies [ Thanks to Faraz ]. It is amazing such alien, other-worldly sounds can be obtained from such otherwise ordinary object. 


We recorded the sound of the slinkies using our frame construction, and the piezo setup we’ve designed last year. The sound at the meetup was absolutely enlightening. You can hear some excerpts what it sounded like from the Soundcloud player above.

Lucia on the other hand experiments with making high frequency musical Arcs, possible by use of high voltage driver and flyback transformer! Head over to Feathercurl’s channel ( feathercurls on Youtube ) to see more wacky sound projects, and be careful not to get electrocuted – High voltage can teleport from the screen into your brain. 

book_physics of musical instrumentsThe Physics of Musical Instruments by Neville H. Fletcher and Thomas Rossing may be something worth investing into. 

piezo‘Addressed to readers with a reasonable grasp of physics who are not put off by a little mathematics, this book discusses most of the traditional instruments currently in use in Western music.’ can be obtained from Amazon.






Finally, here are some more photographs of this evening.

Tute Chigamba: Sun 25th Jan. 2015

This meetup, we were joined by Frederic Roksam; a sound and an acoustic engineer who has experience of working in organisations such as IRCAM and Philips Consumer Electronics. 

One of the participants [ Adam ], playing an African made Mbira, specifically made by the craftsman in the video below. 

The simplicity of the tools being used to sculpt the instrument is astounding. The maker uses a piece of glass to sand the surface of the wood, shapes the steel by simply hammering it.

Our setup that evening included a row of solenoids, mixer, piezo pre-amp circuits, frame, saw blades, piezo discs, laptop, and recorder.
