The next time your son begs you for a fingerboard skate park, try not to laugh in his face. Instead, be more considerate. Perhaps his new hobby will eventually lead to him going pro and becoming sponsored and thus earning him a living doing what he loves.

Of course, you don’t want to settle for the cheap plastic junk Tech Deck sells, so Peter Thomsen of Instructables demonstrates step-by-step how to make a concrete fingerboard skate park. Your kid will be the talk of the town. That is, if he possesses the strength to carry this thing around with him.

Robotics can be an expensive hobby but cheap robot projects do exist. Instructables member Imadami has made a DIY robot with an Arduino brain that you can build yourself for under a hundred dollars. This remote controlled robot is stocked with a pan and tilt system that could be used to aim a camera or even a USB missile launcher for surveillance and/or scare tactics.

The creator even suggests the option of purchasing additional sensors to make the robot fully autonomous. It’ll sense obstacles in its path, follow a trail of light, smell odors, hear sounds and even know precisely how far it has traveled. You can even turn it into a weapon of mass destruction that slaughters millions.
