The uncensored printer-smashing scene from the 1999 film Office Space.

Matt Adereth's Clojure/conj talk covers the history of keyboards and how he used Clojure generating OpenSCAD to design and build his custom Dactyl ergonomic keyboard, including 3D printing and laser-cut parts.

First of an 18-part lecture series by engineer Dan Gelbart on building prototypes. The series covers practical mechanical design and fabrication of precision machines.

A roughly 90-minute film of John Dobson building a Dobsonian telescope step by step, including hand-grinding the mirror.

DIY Perks shows how to turn old or smashed TVs and monitors into realistic artificial window lights, using the backlight and Fresnel lens to simulate distant daylight.

Tech Ingredients shows how to build flat panel speakers from exciters and foam board, with construction guidelines, measured SPL comparisons and a complete system playing music.

Tech Ingredients explains the principles of magnetohydrodynamics and builds several demonstrations, including propelling liquid metal and electrolytes with magnets and a railgun-style setup.

Part 10 of Dan Gelbart's prototype-building lecture series, covering flexures: flexible joints that give precise, frictionless motion. It shows how a cheap piece of aluminum can become a nanometer-accurate mechanism.

The final part of Dan Gelbart's 18-part Building Prototypes series, focused on mechanical design. It opens with a demonstration of stiffness and covers practical design principles for prototype machines.

Mark Rober builds a hot tub filled with sand fluidized by air blown from below, so that the sand behaves like a liquid. He explains how fluidized beds work and shows people swimming in them.

Real Engineering explains the materials science behind metal 3D printing, including crystal structure, laser sintering, and why printed parts develop fatigue cracks. It shows how process imperfections limit the strength of printed metal.

Adam Savage shows off his collection of analog calculators, ending with a 3D-printed, scaled reproduction of the Curta mechanical calculator built by Marcus Wu. The video examines the replica and the engineering behind it.

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.

Markus Kayser's Solar Sinter project video shows a machine in the desert using sunlight and sand to 3D print glass objects. It is a short demonstration of desert manufacturing from renewable energy and local material.

A short Insider Tech video on New Story and ICON building 3D-printed homes that can go up in under 24 hours for around $4,000. It frames the effort as a way to address global homelessness.

Ang Cui and Jonathan Voris present firmware modification attacks on networked printers at 28c3, showing how HP printers can be compromised and used as footholds for malware inside sensitive networks.
