ShopBot SketchPad: a drawing interface
Overview...The SketchPad is a start at a more natural
drawing interface for a ShopBot that lets you draw with a digitizing tablet and
directly create a part file. The thought behind it's development is that it
could be used for things like creating textures or just carving hand-drawn
pictures or signatures, or maybe as a simple interface for kids.
Notes...Requires an open source control (vbtablet.dll) that interfaces with the digitizing tablet. The control, a .bat file that registers it, and the licensing information for the control is included in the download. More information on the control can be found on Sourceforge.

Additional equipment/software required...Requires a digitizing tablet. It's been tested with a small WACOM tablet that has a pressure sensitive tip so that cutting depth can be changed by changing the pressure on the tip. These tablets are available at places like BestBuy for around $100...not sure about other tablets. I wouldn't suggest buying a tablet just to play with the SketchPad, but if you have one you might want to give it a try.
Special instructions...This project requires modifying your Windows registry. The process is automated and painless, but if you're nervous about it this might not be the project for you to play with.
Known Issues...This in one project that works much better with a fast computer because it can sample the points quicker...the faster the better!
