Wow. That’s one big card. I don’t have a use for something like this, but the picture turned up on a robotics forum, so it might have some use in that field. However, it might also find it’s way into the burgeoning CNC field.

The picture above shows the first reasonable homebrew CNC milling device, capable of producing products from ABS plastic. The website is not too clear as yet as to what it can do; however, they do mention a sugar nosel for extruding shapes in sugar.
