Build a Vector Graphics Display Clock with a Cathode-Ray Tube

Electrostatic CRT clocks use X and Y plates to steer the beam. The schematic details amplifiers (often operational amplifiers or vacuum tubes like the EF80) that convert low-voltage signals from a microcontroller into the precise high-voltage swings needed to draw digits, vectors, or circles on the screen.

Remember: In a world of instant-on digital devices, the CRT clock is beautifully, dangerously, analog. Handle with respect. Build a Vector Graphics Display Clock with a

A , often referred to as an "oscilloscope clock," repurposes a small vacuum tube display to show time as a vector graphic. Unlike modern screens that refresh lines of pixels, a CRT clock uses an electron beam to "draw" the clock face and hands directly onto a phosphorescent screen.
