SoundBoxes Workshop


nonlinearity I from macumbista on Vimeo.

Discover the hidden sonic qualities of objects from our everyday world in this hands-on workshop, combining the arts of electronics, noise, sculpture and collage.

SoundBoxes are small, primitive electro-acoustic instruments built from a wooden box, a speaker, a small audio amplifier and a contact microphone. They can create a variety of drone and reverb-type sounds through feedback between the speaker and microphone, as seen in this video. Or they can bring out the hidden sounds found within everyday objects as seen in this video. They also have small touchpoints which can be used to produce a variety of “circuit bending” sounds.

This workshop requires a cigar box or similar wooden box to create the instrument. The box should be a minimum of 16cm tall x 9cm wide x 4cm deep, and the lid must not be thicker than 5mm. Please contact the hosting organizers of the workshop to find out if this box is provided or you must bring it yourself.

Participants may also wish to bring their own found objects and images to create a unique audiovisual cabinet of curiosities. Some guitar effect pedals can also make the box more interesting. All other tools, materials and speakers will be provided.

MAX PARTICIPANTS: 12

LENGTH: approx 5 hours for simple building workshop, up to three days with additional hacking and improvisation possibilities

TECHNICAL NOTES

Simple, right? This SoundBox circuit has a high-gain microphone input leading to a 1/2 Watt audio amplifier which drives a 1-20 Watt speaker, as well as an audio-responsive LED. Additional hacks include a line out for recording purposes and “circuit-bending” style body contacts to transform this SoundBox into a Michel Waisvisz-inspired CrackleBox, all of which will be covered in the workshop.

You can build this yourself, without the printed circuit board, on stripboard using this layout as well. You’ll have to figure out the transistor which makes the LED audio-reactive, as well as the touchpoints, on your own however…

I have used a more complicated circuit with a built-in germanium distortion unit (such as that used in the Ghost Lockets series shown above). You can read more about that one here, but be aware that there is at least one mistake in the artwork which I have noted…

Please also have a look at my Neanderthal Electronics Workshop page for a slightly more technical workshop on noise electronics:
