From the project

Display made of six eight-segment EL display units

Scrolling display board that displays whatever string is published on a given MQTT channel over WiFi.

These displays were used in Russian tanks and missile launch consoles.

Specs - 220VAC @ 400Hz - 0.5-3mA per display four displays: 12mA (max) six displays: 18mA (max) Design alternatives - drive audio amp into (CT?) step-up transformer - DC boost converter into H-Bridge
