Overview

This project is about making a working, robust but "cheap" arcade stick. The stick is to be plugged in USB to a computer in order to play Mame arcade emulator or other games.

This project is made of 3 parts:

• Input multiplexing modules : making it possible for a simple arduino or Atmega chip to hold 30+ almost simultaneous inputs from players
• USB HID Module : The device will create 2 gamepad HID and a keyboard HID on host computer
• Stick body : mainly wood/metalworking in order to get a sturdy case (the arcade stick has to be strong and durable)

Input Multiplexing

Status : In Progress The first module has been soldered and tested

• Module is working
• Modules are daisy chain-able

Toggling an input on is made by connecting +5v to an input pin.

The multiplexing part is designed to be modular.

• Each board is based on a 74hc165N PISO shift register.
• These chips can be daisy chained giving a good opportunity to think about scalability.
• A module handles 8 inputs and uses 4 wires of the arduino (+ power and ground).
