Big Red Button
This is basically a USB keyboard put into a box with one of its keys replaced with a big red button. The function of the button can be changed via two hidden switches at the bottom. The 4 possible states of the switches can set the big red button to either Space, Pause, Scroll Lock or F11.
It can drive an RGB LED strip which can be up to 25 meters long, using music as input. This can come from any device with a line level output (basically all PCs, mobile phones or Hi-Fi systems). It uses a visual equalizer which separates the audio into 3 channels: low, middle and high frequency, and each of these correspond to a specific color. The device also supports passive modes, where no input is needed.
This is my graduation project which I worked on with my partner, Dániel Takács. The goal was to create a software which can map its surrounding into virtual space using a Microsoft Kinect sensor, and then use this map to search for a path where a robot can safely navigate.
