[Rave Rover's Chris Williamson] made a portable DIY dancefloor, sharing instructions and schematics.
Like with many projects similar to this, an Arduino board controls pretty much everything. The floor is dominated by powerful LED lights, which respond to a Serial Peripheral Interface (SPI). A small computer is also inside (complete with Wi-fi), along with a car radio hooked up to speakers. Oh, and thanks to additional wheelchair motors, the floor can be wheeled away to wherever it’s needed.
Chris managed to build the dance floor in just one month, and documented how to do it on Instructables for anyone who wants to make their own. And now you’ve seen this, would you really want to throw a party without one?
