We've all been there — stabbing violently with a broom stick at the annoying, chirping puck on our ceiling, trying to silence it — but a smoke alarm shouldn't be a nuisance, it should passively keep you safe without worrying about it. The Nest Protect ($130) won't drive you crazy, but it will still keep you safe. It features a glowing status ring (green means everything is okay, yellow gives you a warning about a potential problem, and red means there's an emergency), real voice alerts, and an interactive sensor that responds to the wave of a hand, letting you dismiss alerts if you burn your dinner. Set them up throughout your house and instantly access the status of various rooms from your smartphone or tablet, or use them to automatically light your way at night with the pathlight feature. Best of all, it interacts with other Nest devices, keeping you safer without you thinking about it.
Whether you're using it to digitally map your surroundings, scout the terrain for your next outdoor adventure, or realize your lifelong dream of becoming a pilot, the SenseFly eBee Drone ($25,000) is one versatile UAV. Small, light, and portable, the eBee features foam modular construction, letting it break down to fit in a carry-on size case, and launch from your hand — so it's easy to use and take anywhere. It features artificial intelligence and comes with flight planning software, allowing even the most inexperienced pilots to fly and land with ease. Professional-quality mapping software and an onboard 16 megapixel camera give you a view of the ground like you've never seen before, ideal for charting a run down an unfamiliar slope, plotting your course down a river, or just getting a bird's-eye-view of your city.
