This Automated, Rotating Tripod Can Direct Action-Packed Smartphone Videos for You

Leave your selfie stick and stationary tripod behind. A new interactive mount for your smartphone swivels 360° while tracking your every move, letting you star in your own movie or take creative photos without having to recruit a cameraman.

The gadget, called Pivo, is one of the latest products aimed at making smartphone photography and videography more seamless. The device can be called into action by snapping your fingers, saying “cheese,” or tapping a button on the remote or companion app, and it offers a few nifty filming modes that will save you the trouble of editing video footage later.

Versus Mode lets you quickly pan between two subjects at pre-designated times, so it’s perfect for filming rap battles or debate-style videos, according to the makers of Pivo. You can also take timelapse videos in motion, which lets the camera rotate 120°, 180°, or 360° to capture more of your surroundings.

It’s not just for video, either. The panorama mode lets you capture a wide-angle image without worrying about messing up your photo with accidental motion. “No more unnatural photo stitching with duplicate heads or missing arms,” the company promises. Another feature, called ManyMe, helps you create an army of clones by snapping still shots of you in different parts of the frame, then stitching them together in one photograph.

Any smartphone can be attached to Pivo, and it works with both iOS and Android. As the ProVideo Coalition puts it, the device is “a true Swiss Army knife to take your smartphone photography to a new level.”

Pivo is currently available for pre-order on Indiegogo for $79, and orders are scheduled to ship in May.

The Reason Why Your Car’s Turn Signal Makes a Clicking Sound

The clicking of a turn signal ranks among the least-annoying sounds a car can make. Along with the flashing bulb behind the arrow in your car's dashboard, the gentle, rhythmic tick tick tick-ing tones are a sign that your blinker is working properly when you switch it on. Even as technology has progressed, this feature has remained a constant throughout generations of vehicles—or at least that's how it appears to drivers. According to Jalopnik, there's one thing that has changed, though: the actual source of that familiar sound.

The flashing turn signals began appearing in automobiles in the late 1930s when Buick made them standard in some models. Traditionally, the clicking sound is made via heat. Drivers would switch on their blinker, and the electricity would heat up a bimetallic spring in the car, causing it to bend until it made contact with a small strip of metal. When these two components connected, a current would pass through them and power the electric turn signal lights. The bimetallic spring quickly cooled down and returned to its original form, turning off the light, before the whole process started again to create a new flash. As the spring bent back and forth, it created a clicking sound.

The next evolution of turn signals used a similar trick, but instead of moving a spring due to heat, it sent the electronic pulse to an electromagnet via a chip. When activated, the electromagnet pulled up a metal armature and disconnected the current powering the light (or the opposite, depending on the relay setup). Without the pulse from the chip, the electromagnet turned off and the armature returned to old position and bridged the circuit providing power to the bulbs. As was the case with the thermal spring, the relay clicked every time it moved.

Up until recently, this was how most car turn signals functioned, but things have changed as cars have become more computerized. Many car manufactured today rely on computer commands to activate their turn signals, skipping processes that once produced the distinctive clicks. But the clicking sounds are something people grew up with, and drivers might be unsettled if they heard nothing after activating their blinkers. That's why the mechanical sound still exists in the computer era—even though in many modern cars, it's actually just being broadcast through the vehicle's audio system.

Sony Is Celebrating the Walkman’s 40th Birthday With a Retrospective Exhibition in Tokyo

Before the dawn of CD players, mp3 players, and iTunes, cassette tape players dominated the music scene. The Walkman was the most prolific among them, and as designboom reports, Sony is hosting a retrospective to celebrate the 40th anniversary of the gadget's debut.

The Walkman first appeared in stores in Japan on July 1, 1979—just a few months after Sony cofounder Masaru Ibuka (who had already retired at that point) asked Sony executives to create a lightweight cassette player that would allow him to listen to music on long flights. The product was an instant hit, helping make cassette tapes more popular than vinyl and introducing many consumers to portable, personal devices for the first time.

Four decades later, the Walkman is no longer the hottest music technology on the market, but its impact on the industry is undeniable. Sony's new exhibit, titled "#009 WALKMAN IN THE PARK 40 Years Since the Day the Music Walked," explores that legacy. At Ginza Sony Park in Tokyo's Ginza district, visitors can experience the exhibit in two parts. The first is "My Story, My Walkman," which features the stories of 40 celebrities whose lives were changed by the Walkman. The second section is a "Walkman Wall" where about 230 models of the Walkman, from the original cassette players to CD and MP3 players, are on display.

The exhibit opened on July 1, the Walkman's anniversary, and will continue through September 1. Anyone can explore the Tokyo retrospective for free from 10 a.m. to 8 p.m.
