Charles Guan, recent MIT grad, is certainly a certifiable tinkerer. Where I see a skateboard and a snowblower engine he sees a portable off-road skateboard. Completely DIY, it got noticed at the World Maker Faire New York on Saturday.
Sadly, you cannot make lemonade from lemons by pulling the pin on these incendiary pieces of fruit to make them explode. They're inert, you see, and just a side project for tinkerer Chris Myles.
