We don't do a whole lot of reporting on ancient weaponry here, because, well, it's a little dated -- but throw in an Arduino and a servo, and you've got our attention. Take, for example, this miniaturized trebuchet. Constructed from a series of click-in-place pieces known as Blocklets, the little launcher is basically a standalone slingshot. With the addition of the aforementioned components, however, it becomes a motorized annoyance for anyone and anything that stands in its way. The folks behind the tiny trebuchet tested its capabilities against a sculpture similarly built from Blocklets, but we prefer the challenge of a moving target. Unfortunately, we'll have to wait to get all medieval with this thing, as Blockets haven't quite made it out of the funding stage yet.
