Pinball-controller

Repository structure

• controller-PCB - The kicad PCB design for the controller board.
• src - LUA source code to be run with NodeMcu on the ESP8266.

Todo

PCB-design

• Calculate more precise values for transistor resistors.
• New design for Stern pinball machines.
• Find better solution for I/O shortage on ESP12-E.
• Minified design for factory manufacturing.

Firmware

• Make decision on which OS to use on ESP8266. NodeMcu, FreeRTOS, IoTcore etc.
• Communication method/protocol with server.
• Menu traversing method.

Master server

• Decide on which language to use. NodeJS, Python, PHP etc.
• Master server locally on for example Raspberry PI or on the internet with a VPS.

Payment solution

• Evaluate Swish API.
• Look at other payment solutions such as Strip, Paypal, Braintree etc.
• Decide if we should have an account balance system or only direct payments.

Ideas

• RFID/NFC reader mounted at the coin machine. Swipe card/tag/phone to pay from balance.

Kicad dependencies

To view the design in Kicad you need kicad-ESP8266 and Walters kicad libraries
