Generally, for network storage needs, I would recommend getting a dedicated NAS server, such as the Synology DiskStation DS1511+. However, if your needs are limited to casual usage, such as sharing documents and streaming music and photos, then a router with built-in network storage capability -- one that comes with internal storage or can host an external storage device and shares that with the rest of the network -- fits the bill better.

While much inferior to a NAS server in terms of features and especially performance, some routers actually have more to offer, in terms of storage, than one might expect and may just be what you need. In any case, getting a router of this type plus an external hard drive is a lot cheaper than a dedicated NAS server.

Following is a list of five top routers with built-in support for network storage that I've reviewed in recent years. … Read more

N600 routers are the first true dual-band routers on the market, capable of delivering 300Mbps Wi-Fi speed -- based on the dual-stream (or 2-by-2) setup of the 802.11n Wi-Fi standard -- simultaneously on its two frequency bands, 2.4GHz and 5GHz. The marketing term "N600" basically means "Wireless-N standard with a combined bandwidth of 600Mbps."

In layman's terms, an N600 router comes with two built-in Wireless-N access points. Wireless clients connected to one of these access points (a client can only connect to one access point at a time) will have a ceiling speed of up to 300Mbps. In reality, the real-world sustained speeds of wireless routers vary a great deal, depending on the environment, distances between router and clients, and the frequency band.

In my experience, N600 routers generally offer about 60Mbps on the 2.4GHz band and about 140Mbps on the 5GHz band, within 75 feet or less. And while these seem much lower than the 300Mbps ceiling speed, they are more than fast enough for most applications, including high-definition media streaming. In fact, 140Mbps is about 50 percent faster than a wired Ethernet connection. Farther out, from 150 feet or more, a Wi-Fi connection is generally only good for accessing the Internet and mild networking needs. You can find out more about the basics of home networking here.

Since the dual stream is currently the most popular standard of Wi-Fi used in clients, getting an N600 router is probably the best value for your money. This is because the speed of a network connection is determined by the slowest speed of any party involved, so if you get a faster Wi-Fi router (such as an N900 router), you might not see any benefits at all if none of your clients support the higher tiers of Wi-Fi speeds.

Below are the top five N600 routers among those I have reviewed in recent years.… Read more

Dogs and hot cars are a combination that should never happen, but sometimes dog owners leave their pooches in vehicles as they run errands. A new high-tech collar could help prevent dog-overheating deaths.

The Dog Caller combines a SIM card and a thermistor to monitor the temperature around a dog and send the owner a text alert when it nears 80 degrees Fahrenheit. The collar is part of a campaign developed by marketing firm Rethink Toronto for the Toronto Humane Society. … Read more

Autumn is a-comin' down the track, and with it the whiff of rotting leaves and election promises. Robots can clear away the former now, the latter after the revolution.

iRobot is updating its Looj gutter cleaner, a leaf-churner extraordinaire that reduces the time it takes to unclog your gutters.

If you're not familiar with Looj, it's a portable, waterproof, rotating scrubber on treads. You set it in your eavestrough and it trundles along, spitting out leaves, needles, and other gunk with its spinning rubber flaps. Messy but effective. … Read more

Climbing walls have come a long way since phys ed lecturer Don Robinson glued real rocks to a hallway wall at Leeds University in 1964. Just down the street from my office, walls made of plywood reinforced with steel frames sport dozens of different types of holds and graded "problems" -- perfect for staying in shape during the rainy winter months in Portland.

But not everyone lives within walking distance of an indoor climbing hub, so Munich-based design studio Lunar Europe thought up a pretty sleek art piece that doubles as a climbing wall and syncs up with an iPhone app.… Read more

These days a lot of life is programmable. But as an avid gardener, I thought that surely nurturing seeds into little green shoots and then full-fledged fruits and flowers would require a nondigital green digit for years to come.

I was wrong. Plants, it turns out, can be activated.

A battery-powered planter pot called Click and Grow out of Estonia lets you grow real, living plants almost without lifting a finger. Even the vernacular around gardening comes fully updated -- sowing a seed can now be described as "inserting a cartridge," watering the soil is "refilling the … Read more

Not all home theaters are created equal, and the following $2 million Dark Knight-themed setup is in a different league altogether.

Designed by Elite Home Theater Seating for a client in California, the custom Batcave theater features six full-size bat suits; a command and control center; and even an authentic Tumbler replica. While information on the actual A/V hardware is very limited, we do know that movies are projected on a massive 180-inch cinemascope screen. … Read more

The past year in consumer technology has seen significant innovations in product features and design. But beyond functionality, an equally important change is afoot as content on these devices increases in importance, swaying the brands consumers consider while shopping as well as the profit planning of hardware makers.

This focus on content in today's gadgets has also given rise to even more profound change as companies look to control the entire business model -- from hardware production to the revenues that inevitably come from content management and acquisition.

Products like Amazon's Kindle Fire, Samsung's Smart TV and Music Hub, and Microsoft's Surface are evidence of this new dynamic in consumer electronics -- one where the interests of manufacturers, software services companies, and even retailers converge to create a more seamless user experience.

The goal is providing greater synergy between device and platform, but as more manufacturers adopt this strategy, creating vertically aligned, single-brand device families, will consumers gravitate to just a few brands for all of their electronics? … Read more

Forget the zombie apocalypse for a moment. What if a real disaster struck your neighborhood? Where would you, or relief workers, take shelter?

As thousands of Japanese are still coping with the aftermath of the 2011 Tohoku quake and tsunami, Osaka-based Daiwa Lease recently showed off this shipping container, a home for disaster zones. … Read more
