While there's really very little practical purpose for it, this homemade drill is nothing short of awesome. Flickr user s8 built the "drill pendant" with a tiny motor and battery. It's so small the length of the handle is about the width of the maker's index finger.
In a video, s8 shows the drill bit turning and the sound it makes when doing so. Though we suspect a needle or a Swiss Army Knife's awl could probably do anything this DIY drill can, you have to admit that they are nowhere as cool.
