Sometimes, we find a project which uses an Arduino in a manner we'd never previously considered. Katsuomi Kobayashi's latest creation is exactly one of those times: an Arduino-powered virtual reality table-flipping simulator. It's something which makes a little more sense if you're familiar with the Japanese idiom of flipping the tea-table in anger: chabudai gaeshi. Immortalised as the emoticon string (ノ`Д)ノ彡┻━┻, chabudai gaeshi has already inspired an arcade game - Cho Chabudai Gaeshi - and now thanks to Katsuomi's work can be enjoyed in the comfort of one's own home. The project, documented on Katsuomi's Frame Synthesis site, takes the wooden surface of a table, adds a hinge in the middle and some padding to prevent accidents. When the table is flipped over, the action is detected by an MPU-9150 gyroscope and accelerometer connected to an Arduino Uno and translated into virtual reality using the Unity 3D engine and an Oculus Rift headset. The result: all the fun of chabudai gaeshi without any tidying up or broken crockery.
People who have actually done Overturning a Table in Anger are, I think, very few - and it's too dangerous to do normally, and is harder to clean up. That is why I cooked up the "VR Overturning a Table in Anger Simulator", which lets you Overturn a Table in Anger as often as you want, using the Oculus Rift and Arduino.
