The recent development of low cost tangible construction kits has lowered the barriers to entry for amateur and youth hardware designers. In this paper, we discuss the outcomes of a pilot study in which middle school youths set up a game arcade by remixing Scratch games and crafting physical game controllers using the MaKey MaKey and Play-Doh. The analyses focused on the youths' designs and reflections on Scratch remixes, their game controllers, and the culminating arcade. Designing game controllers and setting up the arcade was a productive learning experience for the youths in which they were able to glean insights about how to improve their designs by watching younger students play their games. In the discussion we highlight the parts of the workshop that were most successful, address what we learned about the youths' experiences, develop suggestions for the design of future workshops, and discuss the significance of authentic audience designs.
