Windell Oskay of Evil Mad Scientist was at Maker Faire Bay Area again this year and this time he and Lenore Edman made large models of integrated circuits to show how they worked. In this video Windell walks the viewer through the process of a dual 2-input NOR gate made by Fairchild Semiconductor in the late 1960s.

A quartz watch has a tiny quartz tuning fork that’s been calibrated to vibrate at 215 cycles per second. This signal is fed through a […]
