Cutting Wood LP Recordings on an Epilog Laser

By Amanda Ghassaei | Posted: 03/07/2014 1:26PM


I developed a more accessible way of fabricating wooden records with a laser cutter. These records were cut on an Epilog 120 Watt Legend EXT to a theoretical precision of 1200 dpi (though the kerf of the cut and some tricks I used to avoid crashing the laser cutter dropped the actual precision down by ~1/6).

The audio on the records has a bit depth between 4-5 bit and a sampling rate up to about 4.5kHz. So far I've successfully cut audio on wood, acrylic, and paper, and I'm sure there are many more materials that would work. I wrote the processing sketch that generates the record cutting paths so that it can be modified for any song, material, cutting machine, record size, and turntable speed, find that code and more detailed info about the project on Instructables.

I graduated from Pomona College in Claremont, CA with a BA in Physics and Minor in Chemistry in 2011. My research experience includes topics in nanotechnology, solar cells, and electrochemical and optical sensors. I'm interested in novel applications of digital fabrication, materials science, and developing physical interfaces for the manipulation of digital media. I'm currently working at in San Francisco, CA.
