In September 2016 I had the honour to spend a week as a resident at the Parisian etextile hackerspace DataPaulette.

I could use the facilities set up by expert Maurin Donneaud in order to prepare a set of optical fibers and custom LED boards.
Those parts were necessary for the design of a light-emitting prototype within the frame of the research project DAAN developed at the Design Research Lab, Berlin University of the Arts.
I followed a precise process in order to prepare the fibers to be sanded:
- wrap around a custom-made tool with an even tension the fibers
- screw the weights with additional rubber to make sure the fibers will be held in place and won´t break
- cut at one end, gather the fibers together and polish
- set up a clean workspace (preferably within a plastic box as the fine sand covers your all body, but this was not available then)
- get as much protection for your skin as possible
- switch the light off
- slowly and carefully start to sand, short pulses and the tool at least 30cm from the fibers to get an even diffusing surface
Last but not least, I soldered a few Lulu PCB, designed by Maurin for etextiles purposes.
The Lulu holds the fibers ends directly in front of the power LED and allows for its maximal luminosity.
