We've seen plenty of development boards, but this might be the first that comes with both Bluetooth LE and built-in USB. Tah is the creation of India's Revealing Hour and has been designed to both lower the cost of adding Bluetooth to Arduino projects, but also to connect your smartphone to other devices in the home. For instance, adding an IR shield will enable you to create a universal remote control for appliances and your TV. Even better, is that you can slot the hardware into your games console and use your smartphone as a controller -- in the video embedded after the break, the company uses a smartphone as a substitute PlayStation controller, and there's an Xbox variant that's currently being developed. Naturally, Tah is currently gathering funds over at CrowdSupply, and its makers need $25,000 to begin manufacturing. If you'd like to get your hands on one, then early-bird customers can snag one for $40, while the late-comers will pay 10 dollars more.
