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.

A hobbyist builds a prototype full-frame CCD camera from scratch, with open-source design files and a custom PCB. The video shows the first, still rough prototype.

Joe Barnard of BPS.space shows his model rocket Scout F landing vertically like a SpaceX booster after seven years of attempts. The video documents the successful landing and the build-up to it.

Stuff Made Here designs and builds an "unpickable" lock, then calls in a locksmith to see if it can be defeated. It covers the mechanical design effort and the attempt to pick it.

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.

A hobbyist build-and-experiment video on rotating detonation engines (RDEs), where a continuous detonation wave spins around an annular chamber. The creator 3D prints parts and tests a small engine, while being candid about uncertainty over whether a true rotating wave was achieved.

Mark Rober builds a third-generation glitter bomb trap and films it catching package thieves, with phone trackers and fart spray included. It shows the engineering behind the build and the comic payoff.

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.

Adam Savage and engineer Kipp Bradford build a compact wearable refrigeration system to keep Adam cool under costumes, modeled on the cooling unit in a NASA spacesuit simulator. It is a long, hands-on build session.

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.
