Drake Anthony recreates a historical 17th-century experiment by vacuum-sealing mercury inside custom-blown glass flasks. By mechanically agitating the liquid metal within these evacuated containers, Drake explores the resulting triboelectric glow, experimenting with different noble gas backfills and alternative materials to enhance the light-emitting effect. See the video below:

One summer day in 1941, a British radio operator was monitoring German military frequencies and heard something unexpected in her headphones. A later report called it “strange new music.” Sounding unlike the familiar Morse dit-dit-dah of enciphered messages sent over the German Enigma network, the “new music” was a rhythmic warble of binary teletype code being transmitted at […]

Lee Hutchson went shopping for a clock and he and some specific, but straightforward, wants. He wanted it to just tell the time, accurately, he wanted red digits, and he never wants to set the time…ever. Basically a red seven-segment self-setting “atomic” clock. After some searching he couldn’t find that perfect trifecta so he realized […]

The Raspberry Pi is a wonderful little computer, but one thing it isn’t very good at is controlling DC Servo Motors – these motors need very specific and repetitive timing pulses to set the position. Instead of asking the Pi Linux kernel to send these signals, pop on our handy HAT or Bonnet. These boards […]
