Wallbox Interface Board

Introduction

This repository provides the KiCad project containing the complete circuit schematic, bill-of-materials, and PCB layout for the Wall-O-Matic Interface Board.

The interface board is a device designed to take a Seeburg Wall-O-Matic jukebox remote, a common sight on a sterotypical 1950's diner tabletop, and interface it to a Sonos system via Wi-Fi using an ESP8266 (ESP-12S).

The main repository for the schematics is: https://github.com/dkonigsberg/wallbox-board

The source code for the firmware that runs on this board is here: https://github.com/dkonigsberg/wallbox-code

A good overview of the project can be found in these blog posts:

• Part 1 - Introduction
• Part 2 - Procuring a Functional Wallbox
• Part 3 - Decoding the Pulses
• Part 4 - Inserting Coins
• Part 5 - Designing the Circuit
• Part 6 - Developing the Software

Notes

The component libraries used in this project are a bit of a hack job, pulling from many different sources. The KiCad cache file is included so that the project can actually be opened without having to duplicate this.
