OpenEVSE started in February 2011 with a simple experiment to try to generate the SAE J1772 pilot signal on an Arduino Board. One experiment lead to another to another until a prototype J1772 compatible controller was born. With lots of feedback and interest from the great folks on the "My Nissan LEAF" Forum a few boards were offered to other hardware hackers. What I thought would be a few boards (I built 6 in the first batch and was worried few would want one) turned into more and more... Boards have been built all over the world and are reliably charging many EVs.
OpenEVSE was released as an Open Source hardware and software project in October 2011.
