Instructables user Amandaghassaei has posted a HOWTO for making a 3D printed record that plays on a regular turntable. Her method converts any digital audio file to grooves ready to print. It's a bit fuzzy, but still rather exciting! I'm waiting for the way when taking a snapshot of a vinyl disc can be the first step toward deriving its audio content, converting that back to a shapefile, and printing out a high-fidelity duplicate.
In this Instructable, I'll demonstrate how I developed a workflow that can convert any audio file, of virtually any format, into a 3D model of a record. This is far too complex a task to perform with traditional drafting-style CAD techniques, so I wrote an program to do this conversion automatically. It works by importing raw audio data, performing some calculations to generate the geometry of a record, and eventually exporting this geometry straight to the STL file format (used by all 3D printers). Most of the heavy lifting is done by Processing, an open source environment that's often used for coding interactive graphics applications. To get Processing to export to STL, I used the ModelBuilder Library written by Marius Watz (if you are into Arduino/Processing and 3D printing I highly recommend checking this out, it works great).
I've uploaded some of my complete record models to the 123D gallery as well as the Pirate Bay. Check Step 6 for a complete listing of what's there and what I plan on posting. Alternatively, you can go to Step 7 to download my code and learn how to make your own printable records from any audio file you like.

I want to thank Boing Boing for allowing me to introduce my music collection titled The Triumph of the Will Not.
Gollancz have announced a gorgeous set of new editions of William Gibson’s seminal Sprawl books, which began with 1984’s Hugo, Nebula and Philip K Dick award-winning novel Neuromancer, designed by Daniel Brown (previously), using software that created fractals based on 1970s apartment buildings.
All through 2016, Jessica Leigh Clark-Bojin (aka @ThePieous) has sent us a stream howtos for of amazing, artistic pies — an HR Giger pie, a James Bond pie, and a Predator pie. Now she’s kickstarting a set of pie templates to help you make perfect pop-culture pastry in your own kitchen.
TV antennas are making a comeback, and the Ghost Indoor HDTV antenna is a great example of why. Unlike the old bunny ear-style antennas, this compact antenna is barely noticeable and picks up channels easily. Plus with the addition of streaming services like Netflix, we find ourselves with plenty to watch without a pricey monthly cable bill. The Ghost […]
I’ve never really felt the need to purchase a smartwatch because a lot of them aren’t very functional, but at just shy of $30, the Martian Notifier Smartwatch was worth checking out. For that low of a price, it actually does feature an impressive amount of functionality, and comes in handy when you don’t want to be carrying around your […]
