Crt: Clock Schematic Repack

Z_OFF(); // Move to next digit with beam off

The CRT (Cathode Ray Tube) clock, particularly when built from scratch using vintage components, is a profound intersection of mid-century aesthetics, analog vacuum tube electronics, and modern digital logic. Unlike modern liquid crystal displays (LCDs) that offer a perfect, static image, a CRT clock schematic represents a dynamic, fragile, and artistic endeavor to make time visible through electron bombardment of phosphor.

Without proper linearity correction , your clock digits will appear pin-cushioned or barrel-distorted. Z_OFF(); // Move to next digit with beam

Use a high-voltage op-amp like the (expensive) or a discrete design using 2N5401/2N5551 transistors. Use a high-voltage op-amp like the (expensive) or

: Often paired with an external Dual DAC chip (like the MCP4822) to produce high-resolution vectors for drawing clock faces.
