Hobbyist creates laser cutter that can make playable music records out of wood

It seems like the creative world has a thing for music records of late. Just a few weeks ago, we covered a story on designers who created an interchangeable, color-wheel based music record, and a few days ago, a post went up about Third Man Records releasing their limited edition, precious metal-based Gatsby soundtrack LPs.

This week’s story comes from Instructables, where employee Amanda Ghassaei has reported her development of a laser cutter that carves grooves and tiny bumps into all sorts of materials, including paper, acrylic, and even wood, for the purpose of making music records.

Rather than try and re-word what she’s done, here’s how she described the project, verbatim from her site:

These records were cut on an Epilog 120 Watt Legend EXT to a theoretical precision of 1200dpi (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.

She goes on to explain that she wrote the system’s Processing sketch which cuts the record’s paths, and she made it so that it can be modified on a per- song, material, cutting machine, record size, and turntable speed basis.

Some pretty cool stuff. Check out Ghassaei’s laser record cutter video to learn more:
