Abstract

This paper describes our progress in creating a device called a rototack. In its design, the rototack is an example of a computationally-enhanced craft item: a small, robust, inexpensive, and versatile – but also programmable – physical object for use in a variety of educational and home crafting projects. In particular, the tack is a source of rotational motion, suitable for turning light objects or for powering (e.g.) cams, gears, and linkages in complex, userdefined patterns. We describe the engineering decisions and trade-offs involved in creating our current prototype of the tack; discuss the central issues in creating a programming language and environment for the device; and sketch a variety of potential uses to which the tack might be put.
