Shaka turns smartphones into wind meters, gives surfers and kiteboarders the gnar they need (hands-on)

Ever missed an amazing set in spite of your sick surfboard because you packed it in not knowing that the wind was picking up and about to deliver the perfect wave? Or maybe you didn't realize just how hard the breeze was blowing and as a result, your tee shot wound up deep in the rough. Good news, sporting friends, because start-up company Shaka is here to make you more air-aware with a wind meter that plugs into the 3.5mm jack on your smartphone. It's a small, plastic fan, not much bigger than a box of matches, that pairs with the company's app to deliver wind speed and direction wherever you are -- and it works by simply holding the thing up in a stiff breeze. The app then keeps a record of all your measurements and allows you to share them via your favorite social networks. Not only that, it also overlays the results on a map so you can see where the wind is just right for all your favorite wind-reliant activities. It's currently iOS-only, but we're told Android and Windows Phone versions are in the works as well. The price for knowing when wind perfection is upon you? For now Shaka's seeking to sell them for around $59 bucks, but that could change if the powers that be (read: investors) decide otherwise.

Sassor wants to let users know just how much electricity their gadgets are wasting (hands-on)

Everyone knows that their game consoles, appliances and HDTVs are energy vampires, and while Energy Star-certified products tell us which gadgets are more green-friendly than others, we still don't know just how much juice they're actually sucking down in a given day. Enter Sassor, a start-up from Japan that's created a system to monitor the electrical consumption of anything plugged into a wall outlet -- from PCs to refrigerators. It tracks power consumption using current sensors clamped onto power cords, which communicate wirelessly via ZigBee with an module (based on an Arduino design) that uploads the info to the cloud.

Through the web portal, users can track energy consumption on a per-device basis in real-time, letting them figure out which gadgets are most responsible for their sky-high utility bill -- and take appropriate steps to correct the problem. Currently, it's aimed solely at businesses, but once Sassor's on its feet, funding-wise, the plan is to also put them in people's homes. The company told us it'll ditch ZigBee in favor of a WiFi solution in such future iterations, and it'll make an SDK and the system APIs available to all so that people can program for the platform and improve it in ways currently not contemplated. Alas, there's neither a timetable nor a price for the consumer version just yet, but you can see some pictures of the hardware's innards below.
