Technology Connections follows up on his analog TV video to clear up the debate over whether CRT phosphor dots are pixels. He explains the shadow mask, color triads and how they relate to the scanned picture.

Corning's 2011 concept video showing a future where specialty glass surfaces and touchscreens are woven into everyday life.

Balaji Srinivasan's Startup School 2013 talk on Silicon Valley's Ultimate Exit, arguing for building alternatives outside existing institutions. It is the primary source for a much-retold and much-distorted idea.

A video debunking popular primitive-building YouTube channels, arguing that their digging, concrete and construction are staged. It uses the Primitive Technology channel as a baseline for what is plausible in a natural setting.

A Technology Connections video on JVC's LCCS, a display hybrid that cycles a color LCD shutter over a monochrome CRT to produce field-sequential color without dots or stripes. It builds on his earlier videos about analog TV and compatible color.

A concept video from Nokia Research Center and Cambridge Nanoscience Center showing Morph, a flexible, self-cleaning, shape-changing phone imagined through nanotechnology.

Kurzgesagt's animated explainer on CRISPR gene editing, covering how the technology works and what it could mean for curing disease, designer babies and aging. It frames genetic engineering as an irreversible change coming to humanity.

Technology Connections explains why the superheterodyne radio has its name and how mixing frequencies lets it tune stations well. It walks through the underlying wave phenomena and algebra and why the design solved a hard tuning problem.

Technology Connections shows a cheap method for capturing analog video: a composite-to-HDMI upscaler feeding an HDMI capture dongle, aimed at digitizing home movies and VHS tapes.

Part one of Technology Connections' account of the VHS versus Betamax format war. It argues Sony was caught off guard by JVC's cheaper, more practical VHS system.

Technology Connections explains how analog television produced moving images without computers, covering scanning, CRTs and standards like NTSC and PAL. It is part of a series on analog TV.
