A robotics hackathon is taking place in Toronto late in November called: Get Your Bot On!
It's a weekend event where tinkerers get together to generate ideas for, and build robots.

The hackathon is particularly meant for Arduino users, as the Arduino will be at the core of the kits being provided. If you're in Toronto and you've managed to find this post, then your likely the perfect candidate to join. It is a chance to meet some other makers, and build a cool project together. More info will be forthcoming in the weeks ahead. Please sign up for the email list at the address above to keep up with the latest announcements.
