Meet the AirBoard: an Arduino compatible prototyping board that helps you learn about programmable electronics fast. The device is compact, open source, and wireless. It is compatible with Bluetooth, WiFi, and XBee shields. Just pick the shield that works for your application, connect it to the board, and you are set. The AirBoard offers the same type of solderless connector as the Arduino UNO, so it is beginner friendly.
With this board, you can learn to control your everyday things, interact with wearables from your smartphone, and connect your devices to the Internet. The battery lasts for 3 years. Yet another fun toy for hackers. You can find the project on Kickstarter.
