Hello! My name is Seon, but most people know me as Unexpected Maker.

I’m based in Australia, and I design and manufacture my own range of microcontroller development boards, add on shields and other electronics based products that are enjoyed by hobbyists, enthusiasts and professionals around the world.

I also run a YouTube channel, and do weekly livestreams around electronics projects.
