Camera + Turntable + Laser = 360° Scanner

Camera + Turntable + Laser = 360° Scanner

Sebastian Korczak hacked together a 360° rotating 3D scanner using little more than a record turntable modified with Arduino, digital camera, and a laser pointer. Korczak’s laser was mated with a special lens to create a linear beam. The distortion of this beam as it scanned the room coupled with the video data is put into a Python script, which outputs a point cloud of whatever is scanned. In this manner he is able to get full real-time scans of entire rooms. Fortunately for us, he’s provided extensive documentation on his homepage.

Interesting milestone in open-source 3D printing over at Thingiverse: User crank has published a freely-downloadable magazine for the ubiquitous AR-15 rifle. As downloaded, crank’s magazine only holds five rounds, but a person with basic 3D modelling skills could modify it with little difficulty to produce a “high-capacity” magazine. I’m not sure what the current state of law on magazine size limits is, but prior to the sunset of the Federal Assault Weapons Ban (Wikipedia) in 2004, manufacture of an AR-15 magazine with a capacity of more than 10 rounds was an offense.

Sometimes, I get this feeling like I’ve seen it all – that nothing that comes along is ever going to inspire or delight me the same way that certain ideas, systems, inventions, and/or artworks did when I was younger. It always passes, sooner or later, but while I’m under that spell it can be…well, it can be a bit depressing, honestly. So I feel like I ought to thank International Man of Mystery Nirav Patel, somewhat more personally than usual, for making and sharing this wonderful thing. I am inspired.
