The Goods: November 2013's Hottest Gadgets

The most efficient LED bulb and more

TiVo Roamio Pro

With the TiVo Roamio DVR, a user can watch recorded shows almost anywhere. Any iOS device can connect to the cable box, which has built-in Wi-Fi and can record six shows at a time. It stores up to 450 hours of media. $600Courtesy TiVo

Helios Bars

The Helios Bars have integrated Bluetooth 4.0 and GPS so they can give cyclists turn-by-turn directions. After a user enters a destination on a connected phone, the handlebars' rear-facing left or right LEDs will flash to indicate upcoming turns. $199 (available December)Courtesy Helios

Vaavud Wind Meter

The Vaavud turns a smartphone into a wind-speed gauge. The plastic rotor, which contains four magnets, plugs into a headphone jack. As it spins, the magnetic field around the phone fluctuates. An associated app translates the readings into wind speed, which are as accurate as those by a standalone meter. $50Courtesy Vaavud

Victorinox Bike Tool

The Victorinox Bike Tool is a Swiss Army knife for cyclists. The 3.5-ounce multitool has an L-wrench for tightening screws, eight bits, and a tire lever. The casing is made from an impact-proof and oil- and gasoline-resistant plastic. $48Courtesy Victorinox

Black & Decker 8V Max Impact Screwdriver

The Black & Decker impact screwdriver can spin at 2,200 rpm—more than 10 times faster than a typical cordless screwdriver. When it meets resistance, the tool's impact mechanism kicks in, delivering fast pulses that increase the torque delivered to the screw. $40Courtesy Black & Decker

CCM RBZ Ice Hockey Skates

The RBZ is the most maneuverable hockey skate on the market. The skate comes with customizable arch support and a taller blade holder, which allows players to make turns 10 percent more tightly than players on standard skates. $749Brian Klutch

MakerBot Digitizer Desktop 3-D Scanner

The MakerBot Digitizer desktop scanner fast-tracks the 3-D--printing process. Using a 1.3-megapixel camera and two lasers, it scans objects up to eight inches tall and 6.6 pounds and converts the scan into a 3-D file that can be modified with CAD or sent straight to a 3-D printer. $1,400Courtesy MakerBot

NanoLeaf

Using only 12 watts, NanoLeaf produces 1,600 lumens, making it the most efficient LED lightbulb. Printed circuit boards provide both the bulb's circuitry and structure. And because the 33 LEDs draw so little energy, they also produce little heat, eliminating the need for a heat sink, so the bulb is lighter. $45Brian Klutch

The North Face ThermoBall Full Zip Jacket

ThermoBall insulation is comparable to 600-fill down, but with two critical differences. It doesn't lose its warmth when wet (it's a water-repellent synthetic), and it doesn't clump together because the tiny clusters sit within hundreds of isolated sections. $199Brian Klutch

Garmin VIRB Elite

The VIRB action camera records up to three hours of 1080p video on one charge, the longest life in its class. It also has GPS, an accelerometer, and an altimeter, which can track a user's location, speed, and elevation in sync with the video. $400Courtesy Garmin

Blue Microphones Nessie

The Nessie is the first USB microphone that adapts to any audio in real time. It automatically smooths and levels incoming vocals, instruments, and voiceovers—streamlining editing so audio clips are ready to go faster. $100Courtesy Blue Microphones

MetroNap

MetroNap alerts subway riders when they've reached their destination. Because GPS doesn't work underground, the app makes use of the phone's accelerometer, which detects when the train is moving. With info about the typical commute time between stations, the app sets off the ringer upon arrival. (free)Courtesy MetroNap
