EiMOS : Electrical Impedance to Mahjong Output Scores

A Library for legacy scoring system of Japanese mahjong tables. Formerly known as mahjongAsst. Legacy mahjong scorers implement special score sticks containing electrical elements. My enquiries clarified that the elements are R / L / C passive components. This library measures parallel resistances/capacitances of stack-piled score sticks, and convert the values into actual scores of 4 mahjong players

EiMOS is in NO WAY RELATED to EIMOS, a military vehicle brand of Spanish defence company EXPAL. Library EiMOS isn't intended for military uses.

Features

-Realtime score tracking for all 4 people

-Outputs error message when the sticks are in wrong places

-Manage display mode(NORMAL, DIFF, PM) with push buttons for each player

-Manage honbas with a push button

Supported Models

Resistors

AMOS MONSTER, NINJA, etc

Capacitors

CENTURY TENPAL GOLD

CENTURY TENPAL SILVER

Custom

You make your own system, becuase everything is just a passive element value.
