Retrofitting an existing home with so-called "Internet of Things" gadgets isn’t exactly cheap. A Nest Learning Thermostat, for example, will run you $250 while connected appliances such as a refrigerator can set you back $3,000+. Amenities like being able to remotely adjust the temperature inside your home or receiving a text when the laundry is done certainly sound appealing, but are they really all they’re cracked up to be? Wouldn’t it be nice if you could just try these features out for a week or two before committing to shelling out hundreds or thousands on a standalone IoT-enabled device? With littleBits’ new Smart Home Kit, you can do just that. littleBits is an ever-growing open source library of small electronic modules that easily connect together. Created by Ayah Bdeir, it started as a tool to help designers incorporate electronics into the prototyping process. Today, it’s much more than that. Think of them as Lego bricks for the iPad generation. Read the complete review.
