Da Vinci "knows" what to draw thanks to another great open source tool, Inkscape. "Inkscape is is a professional vector graphics editor for Windows, Mac OS X and Linux." The cable running up Da Vinci's right arm links him to the laptop, where we have created illustrations for him to use, like the Centennial Lady Maria made in Scratch.
The wire figure, Da Vinci, is a third version from the original which debuted at Bay Area Maker Faire in 2012. Alex designed and built DA Vinci 3.0 using pliers, a drill, and a reel of rebar tie wire. Alex has an uncanny gift for bringing images in his head to life, in drawings and in 3-D. Da Vinci's arms and stance are not only aesthetic, they are calculated to move appropriately and fit around the desk and motors. The hand was fitted with the Z motor and special plate that holds the magnets and calibrated Sharpie holder.
At the next event we plan to have BOoM and our URL printed on Da Vinci's drawings. And wouldn't it be great to have the resources to let more children use Inkscape to make their own pictures, too? Dreaming big. Dreaming BOoM!
