The "mini-computer" resp. RAINKIT (Raspberry Pi - www.raspberrypi.org) is a computer in credit card size, which includes everything to easily connect the Internet to the Printer and make it RAIN. Its tiny dimensions, its low price and its high computing power allow the device and its created web site to be shared with other projects, places, conflicts and their questions all around the world. Do you want to let it rain in your context? Get in touch with us, tell us about it and we'll send you the the RAINKIT - for free. You're only obliged to use this site for your project and send the KIT back after the RAIN.
