Arduino platform. Well now you can shrink your creations even smaller, thanks to a rejiggered form factor called the Arduino Nano. Capitalizing on the popularity of the previous Mini version, the Nano gets further downsized, reducing the components into a layout about the length and width of a stick of gum -- without sacrificing any of the functionality. Be honest, you're brainstorming some gum-pack-sized project right now, aren't you? Luckily you won't have to wait long -- the Nano will be available from Gravitech in June for an economical $49.99.
