DIY class-D amplifier
Ben from West Lafayette, IN, wrote in to share his amp project. A Class-D amplifier operates the output transistors as switches instead of as variable resistors, as in more traditional amplifiers. In doing so, nearly all conduction losses in the output power devices are eliminated, leading to a very efficient amplifier.
Ternary kinetic sculpture
There’s something mesmerizing about a steel ball on a track. It’s the anticipation, I suppose. In Thinking Machine by Martin Riches and Masahiro Miwa the artists have cleverly implemented a ternary computer with levers and tracks that constantly cycle steel balls down internal structures towards three chimes that ring out a computed melody.
