Yet another example of how to enter the bigtime with your electrical ideas. Learn form example:
MIT Media Lab researchers Jay Silver and Eric Rosenbaum have designed an Arduino input device that lets you use any electricity-conducting material as a touchpad. Called ‘Makey Makey’, the device works by completing an electrical circuit with any conductive material such as vegitables, pencil lead or one's self to interact with the internet or programs on your computer. For example; you could play games Super Mario Bros by connecting the alligator clips to Play Doh buttons or play a piano program using bananas as the keys.
The research team designed Makey Makey around an Atmel ATMega32u4 8-bit AVR RISC-based microcontroller that runs Arduino Leonardo boot-loader and uses a USB 2.0 port to interface with a computer running an up to date OS (Windows XP, Vista, 7 and Mac OSX). The touchpad device requires no software to run as the PC recognizes it as a regular input device such as a keyboard or mouse and ,therefore, can run anything that uses those peripheral input devices. The team used Kickstarter to fund the Makey Makey project and was successful in reaching over $190,000 US with a target goal of $25,000. The device sells for $35 US (through Kickstarter) and comes with the board, USB cable, a set of alligator clips and your imagination.
