Test driving a Soviet (USSR) Russian IEL (El Wire/Panel).
Smart socket design in order to cascade from 1 display to the next making it easy to use many displays in a string.
Controller driving it is a WeMos (ESP8266).
Power supply is a standard el wire supply; however, the displays require a higher voltage and lower frequency. Can't change the frequency (target of 400Hz), so I upped the supply voltage from 12volt to 14+volt in order to get a higher output voltage on the power supply to make the display brighter now at nearly 180volt.
8 different display panels in the set.

Aliens don't have a period. The standard 7segment units have a period and one have a comma and some are clearly green a some blueish. This can be changed with various power settings.
Test is a boot sequence to make sure they are wired correctly/operate, then digits 0 through 9 and finally random numbers every half second.
