A University of Michigan Medicine demonstration of building a cheap DIY air purifier from a box fan and a HEPA or high-MERV filter using hardware-store parts. It explains why this helps against dust, smoke and viruses and ties it to local air quality readings.

Applied Science builds a replica Apollo DSKY using an electroluminescent driver circuit and screen-printed conductive ink, with source and PCB files published.

Builders Matt Risinger and Jordan Smith visit a Swiss cross-laminated timber factory that makes thick all-wood walls with no traditional insulation and wooden nails instead of glue or chemicals. The video is sponsored by Siga.

Essential Craftsman follows up on his earlier video about a DIY approach to sleep apnea. It centers on forcing nose breathing during sleep with mouth taping and nasal strips, and says to seek medical guidance.

Linus Tech Tips replicates the Threadripper workstation Linus Torvalds built for himself, discussing the parts such as the CPU and cooler.

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.

DIY Perks shows how to modify devices that use older USB connectors so they charge and connect over USB Type-C. He solders in a USB-C connector board and works through cases such as dongle-dependent gadgets and a mouse receiver.

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.
