Dan Gelbart shows his home-built air bearing CNC lathe and grinder, which reaches about 1 micron accuracy. He demonstrates the machine and its parts.

Tech Ingredients shows how to build cheap, high-performance flat-panel speakers using audio exciters on sheet materials such as foam-core board. It explains how distributed-mode speakers work and walks through experiments to find good designs.

Ben Krasnow shows the first image from his home-built scanning electron microscope, after months of work, and walks through how the parts operate together.

Google engineer Dany Qumsiyeh presents a prototype automatic, non-destructive book scanner that turns pages and captures high-resolution images, built in Google's workshops. The talk includes a live demo and a short technical overview.

Naomi Wu documents her project helping Martha Lillard, one of the last polio survivors living in an iron lung, by fabricating replacement neck collars in Shenzhen. She reports the collars worked.

A Disney Research SIGGRAPH 2013 demo of an interactive system that lets non-experts design animated mechanical characters. The user sketches motion curves and the system generates optimized mechanisms and gear trains for 3D printing.

Simone Giertz presents Truckla, a homemade pickup truck conversion of a Tesla Model 3, shown in a short humorous promo.

Mark Rober spends eleven months building and testing a glitter bomb package with GPS and cameras to get back at porch pirates who steal parcels.

Peter Sripol shows his homemade Part 103 electric airplane flying, built from hobby brushless motors and batteries. The video covers the first flight out of ground effect.

Ben Krasnow of Applied Science builds a DIY microbalance from an analog panel meter with an optical servo loop. It reaches about 5 micrograms of precision and is used to weigh a single eyelash at around 35 micrograms.

A step-by-step guide to building a lifter, a small triangular ionocraft made from balsa wood, aluminum foil and thin wire, powered by a high-voltage supply. It also shows high-voltage safety practices.

Sean Hodgins shows the build of the Arduino-based glitter bomb package-theft trap he made with Mark Rober, covering the electronics and the problems that came up. The code and schematics are on GitHub.

Ben Heck modifies a keyboard with magnets, Hall effect sensors and an Xbox controller so the WASD keys give analog control. He walks through the hardware build.
