Who needs expensive commercial EV chargers when you have Arduino, open-source software, and a willingness to learn? This talk chronicles my journey building a fully functional EV charger from scratch, covering everything from safety considerations and electrical engineering basics to the software stack that manages charging protocols.

A simple EVSE (electric vehicle supply equipment or “wall charger”) built using an Arduino and open source software.

Inspired by OpenEVSE and Arduino EV J1772 Charging Station.

During COVID-19, I built a platform using Java, AWS DynamoDB to play a popular board game called “Great Western Trail” online with friends.
