In this American Masters clip, Jacques Pepin shows two different techniques for making a perfect omelet, a dish he is famous for teaching America.

James Hoffmann demonstrates his technique for a clean, sludge-free cup from a French press: stir, break the crust, wait, and carefully pour. It is a four-minute guide.

Jacques Pepin makes a classic French omelette in a short uncut demonstration. The video contrasts it with the American style.

Dr. Mark Cucuzzella of the Natural Running Center gives a short instructional video on natural running form. It describes the principles of good technique, including barefoot-style mechanics.

A three-minute demonstration of professional hand-soldering techniques for multi-lead surface mount parts, to IPC class 3 criteria.

James Hoffmann demonstrates his recommended technique for brewing coffee with a Hario V60 or other cone-shaped dripper, with notes on water and filter papers.

Jacques Pepin demonstrates deboning a whole chicken, quickly and with complete control. It is a short, wordless-feeling technique demo that shows a skill most cooks never learn.

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.

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.

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.

Tech Ingredients builds a pair of large Voigt speakers and explains ported, transmission line and horn designs. It tests them in an anechoic chamber and uses constrained layer damping for the enclosure.
