Maker and classic know-how fanatic Daniel Ross has taken the cathode-ray tube (CRT) show from an outdated camcorder and turned it right into a persistence-of-vision (POV) “3D-ish” show for an audio oscilloscope: the Tachyscope CRT.
“Ever puzzled what occurs while you ‘spin’ a CRT to try to create a 360° picture? Nicely it really works… sort of,” Ross writes of his creation. “In actual life the 360° view works nice, the digital camera pics or video chops up the consequence each time I try to video or take photographs. What you find yourself with is an audio wave type throughout the circumference of the dinner plate.”
The Tachyscope CRT is an amalgamation of upcycled elements salvaged from different units — mounted on a literal dinner plate. The show is a compact CRT from a broken camcorder, initially used because the viewfinder. This tiny tube, measuring simply 1″, is then stripped down to only its vertical coil and linked to a child monitor for wi-fi audio reception — the output of which can be routed to a speaker, to offer each audible and visual suggestions.
As audio is performed, the whole meeting spins in a circle — the CRT drawing a reside oscilloscope-like graph of the audio because it whizzes round. The result’s reside audio visualization with what Ross calls a “3D-ish” “holographic” impact.

“Model 1.0, I had used 4× AAA batteries for powering the rig,” Ross notes of the Tachyscope’s evolution. “Model 2.0, I used an air core transformer (wi-fi energy) [and] added a small DC motor with pace management for rotation of the rig.”
