Build a Vector Graphics Display Clock with a Cathode-Ray Tube
: Usually powered by 3.3V or 5V, this section uses a microcontroller like an ESP32 or a PIC MCU to track time and generate X (horizontal) and Y (vertical) signals.
: The tube itself, which includes the heater, cathode, control grid (G1) for brightness, and focusing anodes. 2. Power Supply Schematic Details
