Tribal Sin Wave

E textile summercamp 2017 experiments

Experimentations in making a DIY low tech laser that can give a visual feedback of the different frequencies that are being played.

A coil was made and used as a sort of vibration motor. It is controlled with low frequencies ranging from 30/40 hz. Trying to get it vibrate a maximum using a light and rigid surface. With Esteban and Judith we used a laser and put a mirror on the magnet and placed it in the middle of the coil.

With this technique we can actually visualize the sin wave of the sound frequency.

Using a UV sensitive ink, the laser marked a ephemeral print of the light on the fabric.

Another idea would be to continue by experimenting with the resonant frequencies of materials by attaching directly a very light speaker on the material.

This experimentation was part of the wicked future foucus group at the e-textile summercamp 2017 where we imagined a speculative scenario of what this e textile community leaves behind and how it could be interpreted in the futur by archaeologists or anthropologists. Tourists were invited in a “reserve” that recreated and re interpreted the e-textile artefacts leading to different spiritual, techno-chamanist references.
