DIY Perks builds a webcam mod using a two-way mirror in a box so the camera sits behind the screen image. This allows real eye contact on video calls.

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.

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.

The Plasticity creator explains what a geometry kernel is and compares commercial options C3D, ACIS, and Parasolid, describing his months of research and why he chose as he did.

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.

LightningOnDemand revives a pulsed Lorentz plasma cannon, using modern capacitors to extend its range and increase the delivered energy. It is a high-voltage, high-current hobby demonstration.

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.

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.

Quint BUILDs tests a rooftop water storage setup in which solar power pumps water up to the roof and a turbine generates power later. He works through the numbers to show how much energy it actually stores.

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.

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.

A Veritasium video touring Relativity Space and explaining why 3D printing whole rockets cuts tooling costs, allows rapid iteration, reduces part count and enables new designs. It includes an interview with Scott Manley on aerospace engineering.

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.

Mark Rober's holiday video features the near-final version of his glitter bomb package, built to deter thieves. It is part of his series of elaborate revenge traps against porch pirates and car thieves.
