The Espruino comes pre-installed with both a command line environment and a graphical interface. Just plug it into your computer via the built-in USB port or connect wirelessly through an optional Bluetooth module (which can be soldered to the underside) and start typing away in a normal terminal window or a custom-built Chrome web app, which has a graphical code editor for non-coders and kids. Coding feedback is instant: No flashing, resetting, or compiling is required for changes to take effect.
Gordon Williams, the Espruino’s creator, has already built working prototypes and lined up a manufacturer, but the Kickstarter will allow him to order the controllers in bulk and drive the price down (the reward-level price point is £19, or about $30) along with documentation, tutorials, and improvements to the Chrome app that will make the visual programming interface even easier to use. If funded, the Espruino code and chip designs will be made open source, which Williams hopes will help cultivate a widespread community of makers like the one that made the Arduino a hacker sensation.
