It looks like a fun conference badge, and it is one, but it is also a real tool: plug it into your laptop and it becomes a CAN-to-USB adapter. With it, your laptop can listen and talk on a CAN bus, the network that connects the electronics in cars and in many machines.</p> <p>The badge was designed by <a href="https://woldhack.nl/">Philip Woldhek</a>. In this post we look at where the design comes from, what&rsquo;s on the board and how you can use it.</p>
