DIY Plush USB Game Controller: Hug and Play
We’ve seen all kinds of game controller plushies, but I think this is the first time I’ve seen one that can actually be used to play video games. Adafruit’s Becky Stern built the soft controller using their Flora Arduino-compatible platform and some conductive thread and fabric.
Even though Becky’s design looks like a squishy, oversize NES controller, your computer will recognize the plushie as a USB keyboard, so you can use it with any keyboard-based game. If you’re handy with stitching, perhaps you can modify Becky’s guide and make a plushie of your favorite controller. It would probably take a long time to build a full keyboard plushie though.
