This tutorial works with both official Nintendo or 3rd party nunchucks. The nunchuck is a good multi-use input for a Raspberry Pi as they can be picked up cheaply and contain a joystick, a three-axis accelerometer and two buttons in a nice ergonomically friendly controller.
allows you to attach a Nintendo Wii Nunchuck to your Digispark and use the accelerometer, analog stick, and buttons for your project (robot control!) or send the data to the computer over USB. With the included example you can even use it as a USB joystick!
Floating — a new album by Danish electronic artist Rumpistol / Red Baron — design studio Futura Epsis 1 made something that was a bit of both.
Floating’s live show features a hypnotic 3-D display, controlled by an iPad app, that you can download for your home. The idea is that the show can be projected anywhere — from large arenas to living rooms. “We came up with the idea of a realtime 3-D sound-visualization as an installation for concerts and live-events as well as interactive installation for clubs,” says Andreas Rothaug, Head of Development Futura Epsis 1.
