11 Smart Ways to Reuse Your Old iPhone or Android

Sure, you can sell back or donate your old phone when you upgrade—but you can also keep that old smartphone and put it to other inventive uses around your home. Here are a few of them.

1. A REMOTE CONTROL

Most of the newer Android devices from Samsung, LG, and HTC come with a built-in infrared blaster, which works with your TV, DVR, cable box, or DVD/Blu-ray player. You just need to download an app like IR Universal Remote from the Google Play Store to turn your device into a remote control. If you have an Apple TV, you can use your old iPhone as an alternate remote for your set-top box.

If you have an older device or one that doesn’t have a built-in IR blaster, there’s still hope. Some companies make external IR blasters that allow you to connect your phone via bluetooth, which then gets transmitted to the TV via a special device.

2. A DIGITAL CAMERA

If your old smartphone has an 8-megapixel camera or higher on its rear, then you have a decent enough sensor to turn it into a dedicated point-and-shoot digital camera—one that can upload photos directly to your social media accounts when you get to a Wi-Fi network. You can even buy lenses from olloclip.com or photojojo to make your old iPhone’s photos crisper, wider, and more dynamic.

3. and 4. A BABY MONITOR AND A HOME SECURITY SYSTEM

Video baby monitors can get pretty pricey; put that cash toward diapers and use your old smartphone instead. All you need to do is download an app like Cloud Baby Monitor or Baby Monitor 3G (which both retail for $3.99), place your old phone so that it looks into the crib, connect it to your home Wi-Fi network, and use another device or computer to watch your child from afar.

The same thing goes for a security system in your home. If you want to keep an eye on your house (or monitor what your cat or dog are up to) while you’re at work, download an app like Presence and buy a robotic viewing stand that can rotate a full 360 degrees. After placing the phone in the stand and connecting it to your home Wi-Fi network, you can use the app to turn the phone in any direction to ensure that all is well.

5. A KITCHEN COMMAND CENTER

A kitchen can be a hazardous place for an expensive smartphone or tablet. Keep your current device clean by using an old phone to store recipes and search for cooking videos on YouTube. There are a number of recipe apps, including HotPot and BigOven, that can help with a big family dinner, while apps like How to Cook Everything guide you through the process of making fresh pasta. With note-taking apps like Evernote and Google Keep, you can sync shopping lists across all of your smart devices. You can also use Siri or Google Now to set timers. 

6. A CAR GPS

As long as your device has GPS capabilities, it can be used as a navigational device—even if you don't have a data connection. Most of the smartphones made within the last five years have GPS built-in, so all you need are the proper apps to get the most out of your old iPhone or Android device on your next road trip. TomTom USA, CoPilot GPS, and NavFree USA all offer offline regional maps and turn-by-turn directions; you just need to download the area map on your home Wi-Fi network before you hop into your car. A map of the entire United States could take about 2 GB of space, so make sure your old device has plenty of room or a microSD card slot for additional storage. While these apps range in price from $10 to $40, Google Maps offers the same offline capabilities for free.    

7. A SKYPE STATION

Set up your old iPhone or Android device as a dedicated webcam for Skype or other VoIP (Voice over Internet Protocol) services, such as Vonage and Google Hangouts. Just make sure you have steady Wi-Fi and a desktop dock or stand to make video and voice calls to your family and friends. If you have an iPhone 4 or iPad 2 or higher, you can still use your old iOS device for FaceTime with your loved ones over a good Wi-Fi connection.  

8. AN E-READER

Why let a perfectly good screen go to waste? If your old smartphone’s screen is still in good shape, turn it into a dedicated e-reader. Just download apps like Amazon Kindle, Barnes & Noble Nook, or Google Play Books to read books on your device. You can even download apps like Pocket or Instapaper to read articles you saved from your favorite websites to read later.

9. AN ALARM CLOCK

It might not be the most exciting way to repurpose your old smartphone, but turning it into a nightstand clock might get you out of bed on time. There are a number of clock apps, like Nite Time and Night Clock, that are simple and reliable, while apps like WakeVoice and Alarm Clock HD can give you weather updates and the latest news when you awake. 

10. A TOY FOR YOUR KIDS

Your kids already can't get enough of your smartphone, so when it’s time to upgrade to something newer and shinier, give your old one to them. You’ll give them endless ways to play games and watch videos, but be sure you take some time to back up your data and wipe the phone back to factory settings before you hand it over.

For iOS users, connect to your home Wi-Fi network and then go to “Settings,” then “iCloud,” and then “Backup.” Turn on “iCloud Backup,” select your device, then start the backup process. Once that’s complete, connect your iOS device to your computer and launch iTunes. In the “Summary” panel, click “Restore” and confirm factory reset.

For Android users, connect to your home Wi-Fi network, and then go to “Settings,” then “Backup & Reset.” Make sure “Backup My Data” is set to “On.” Once it’s done backing up all of your photos, passwords, and contacts to your Google account, go to “Factory Data Reset” to restore your phone to its original factory settings.

After you reset your device—but before you hand it over to your kid—set the phone with parental control or restricted access, so your child don't spend hundreds of dollars on in-app purchases or access inappropriate content or websites. Make sure you set up a password or PIN for every download on your device, so that he or she has to ask for your permission every time they want to download something or make an in-app purchase. After you restrict access, download kid-friendly games, apps, and YouTube Kids, which can only access videos suitable for children. 

11. A TOOL FOR SCIENCE 

You can donate your old device’s idle computing power to advance scientific research from around the world. The projects include everything from exploring new medical therapies to the discovery of planets and stars.

Research scientists at UC Berkeley’s Space Sciences Laboratory developed an Android app called BOINC (Berkeley Open Infrastructure for Network Computing), which allows the researchers to tap unused processing power from smartphones and put it toward analyzing data or running simulations that would otherwise be too expensive and costly. BOINC users are volunteering their mobile phones' resources and power to essentially build a large supercomputer for scientific research. 

By default, BOINC taps into your smartphone’s computing power only when it’s plugged in, charging, and not in use. The Max Planck Institute, National Science Foundation, and Google Inc. have funded the BOINC project and app with assistance from IBM. BOINC and its volunteers help popular research projects, such as searching radio telescope data for pulsars and finding more effective AIDS therapy and treatments. Currently, researchers and app developers are working on bringing BOINC to iOS devices

11 Black Friday Purchases That Aren't Always The Best Deal

Black Friday can bring out some of the best deals of the year (along with the worst in-store behavior), but that doesn't mean every advertised price is worth splurging on. While many shoppers are eager to save a few dollars and kickstart the holiday shopping season, some purchases are better left waiting for at least a few weeks (or longer).

1. FURNITURE

Black Friday is often the best time to scope out deals on large purchases—except for furniture. That's because newer furniture models and styles often appear in showrooms in February. According to Kurt Knutsson, a consumer technology expert, the best furniture deals can be found in January, and later on in July and August. If you're aiming for outdoor patio sets, expect to find knockout prices when outdoor furniture is discounted and put on clearance closer to Labor Day.

2. TOOLS

Unless you're shopping for a specific tool as a Christmas gift, it's often better to wait until warmer weather rolls around to catch great deals. While some big-name brands offer Black Friday discounts, the best tool deals roll around in late spring and early summer, just in time for Memorial Day and Father's Day.

3. BEDDING AND LINENS

Sheet and bedding sets are often used as doorbuster items for Black Friday sales, but that doesn't mean you should splurge now. Instead, wait for annual linen sales—called white sales—to pop up after New Year's. Back in January of 1878, department store operator John Wanamaker held the first white sale as a way to push bedding inventory out of his stores. Since then, retailers have offered these top-of-the-year sales and January remains the best time to buy sheets, comforters, and other cozy bed linens.

4. HOLIDAY DÉCOR

If you are planning to snag a new Christmas tree, lights, or other festive décor, it's likely worth making due with what you have and snapping up new items after December 25. After the holidays, retailers are looking to quickly move out holiday items to make way for spring inventory, so ornaments, trees, yard inflatables, and other items often drastically drop in price, offering better deals than before the holidays. If you truly can't wait, the better option is shopping as close to Christmas as possible, when stores try to reduce their Christmas stock before resorting to clearance prices.

5. TOYS

Unless you're shopping for a very specific gift that's likely to sell out before the holidays, Black Friday toy deals often aren't the best time to fill your cart at toy stores. Stores often begin dropping toy prices two weeks before Christmas, meaning there's nothing wrong with saving all your shopping (and gift wrapping) until the last minute.

6. ENGAGEMENT RINGS AND JEWELRY

Holiday jewelry commercials can be pretty persuasive when it comes to giving diamonds and gold as gifts. But, savvy shoppers can often get the best deals on baubles come spring and summer—prices tend to be at their highest between Christmas and Valentine's Day thanks to engagements and holiday gift-giving. But come March, prices begin to drop through the end of summer as jewelers see fewer purchases, making it worth passing up Black Friday deals.

7. PLANE TICKETS AND TRAVEL PACKAGES

While it's worth looking at plane ticket deals on Black Friday, it's not always the best idea to whip out your credit card. Despite some sales, the best time to purchase a flight is still between three weeks and three and a half months out. Some hotel sites will offer big deals after Thanksgiving and on Cyber Monday, but it doesn't mean you should spring for next year's vacation just yet. The best travel and accommodation deals often pop up in January and February when travel numbers are down.

8. FOOD AND SNACK BASKETS

Fancy fruit, meat and cheese, and snack baskets are easy gifts for friends and family (or yourself, let's be honest), but they shouldn't be snagged on Black Friday. And because baskets are jam-packed full of perishables, you likely won't want to buy them a month away from the big day anyway. But traditionally, you'll spend less cheddar if you wait to make those purchases in December.

9. WINTER CLOTHING

Buying clothing out of season is usually a big money saver, and winter clothes are no exception. Although some brands push big discounts online and in-store, the best savings on coats, gloves, and other winter accessories can still be found right before Black Friday—pre-Thanksgiving apparel markdowns can hit nearly 30 percent off—and after the holidays.

10. SMARTPHONES

While blowout tech sales are often reserved for Cyber Monday, retailers will try to pull you in-store with big electronics discounts on Black Friday. But, not all of them are really the best deals. The price for new iPhones, for example, may not budge much (if at all) the day after Thanksgiving. If you're in the market for a new phone, the best option might be waiting at least a few more weeks as prices on older models drop. Or, you can wait for bundle deals that crop up during December, where you pay standard retail price but receive free accessories or gift cards along with your new phone.

11. KITCHEN GADGETS

Black Friday is a great shopping day for cooking enthusiasts—at least for those who are picky about their kitchen appliances. Name-brand tools and appliances often see good sales, since stores drop prices upwards of 40 to 50 percent to move through more inventory. But that doesn't mean all slow cookers, coffee makers, and utensil prices are the best deals. Many stores advertise no-name kitchen items that are often cheaply made and cheaply priced. Purchasing these lower-grade items can be a waste of money, even on Black Friday, since chances are you may be stuck looking for a replacement next year. And while shoppers love to find deals, the whole point of America's unofficial shopping holiday is to save money on products you truly want (and love).

Food
The Origins of 5 International Food Staples

Food is more than fuel. Cuisine and culture are so thoroughly intertwined that many people automatically equate tomatoes with Italy and potatoes with Ireland. Yet a thousand years ago those dietary staples were unheard of in Europe. How did they get to be so ubiquitous there—and beyond?

1. TOMATOES

For years, the wonderful fruit that’s now synonymous with Italy was mostly ignored there. Native to South America and likely cultivated in Central America, tomatoes were introduced to Italy by Spanish explorers during the 1500s. Shortly thereafter, widespread misconceptions about the newcomers took root. In part due to their watery complexion, it was inaccurately thought that eating tomatoes could cause severe digestive problems. Before the 18th century, the plants were mainly cultivated for ornamental purposes. Tomato-based sauce recipes wouldn’t start appearing in present-day Italy until 1692 (although even those recipes were more like a salsa or relish than a sauce). Over the next 150 years, tomato products slowly spread throughout the peninsula, thanks in no small part to the agreeable Mediterranean climate. By 1773, some cooks had taken to stuffing tomatoes with rice or veal. In Naples, the fruits were sometimes chopped up and placed onto flatbread—the beginnings of modern pizza. But what turned the humble tomato into a national icon was the canning industry. Within Italy’s borders, this business took off in a big way during the mid-to-late 19th century. Because tomatoes do well stored inside metal containers, canning companies dramatically drove up the demand. The popularity of canned tomatoes was later solidified by immigrants who came to the United States from Italy during the early 20th century: Longing for Mediterranean ingredients, transplanted families created a huge market for Italian-grown tomatoes in the US.

2. CURRY

An international favorite, curry is beloved in both India and the British Isles, not to mention the United States. And it turns out humans may have been enjoying the stuff for a very, very long time. The word “curry” was coined by European colonists and is something of an umbrella term. In Tamil, a language primarily found in India and Sri Lanka, “kari” means “sauce.” When Europeans started traveling to India, the term was eventually modified into “curry,” which came to designate any number of spicy foods with South or Southeast Asian origins. Nonetheless, a great number of curry dishes share two popular components: turmeric and ginger. In 2012, traces of both were discovered inside residue caked onto pots and human teeth at a 4500-year-old archaeological site in northern India. And where there’s curry, there’s usually garlic: A carbonized clove of this plant was also spotted nearby. “We don’t know they were putting all of them together in a dish, but we know that they were eating them at least individually,” Steve Weber, one of the archaeologists who helped make this astonishing find, told The Columbian. He and his colleagues have tentatively described their discovery as "proto-curry."

3. THE BAGUETTE

Several baguettes

A quintessential Gallic food, baguettes are adored throughout France, where residents gobble up an estimated 10 billion every year. The name of the iconic bread ultimately comes from the Latin word for stick, baculum, and references its long, slender form. How the baguette got that signature shape is a mystery. One popular yarn credits Napoleon Bonaparte: Supposedly, the military leader asked French bakers to devise a new type of skinny bread loaf that could be comfortably tucked into his soldiers’ pockets. Another origin story involves the Paris metro, built in the 19th century by a team of around 3500 workers who were apparently sometimes prone to violence during meal times. It’s been theorized that the metro foremen tried to de-escalate the situation by introducing bread that could be broken into pieces by hand—thereby eliminating the need for laborers to carry knives. Alas, neither story is supported by much in the way of historical evidence. Still, it’s clear that lengthy bread is nothing new in France: Six-foot loaves were a common sight in the mid-1800s. The baguette as we know it today, however, didn’t spring into existence until the early 20th century. The modern loaf is noted for its crispy golden crust and white, puffy center—both traits made possible by the advent of steam-based ovens, which first arrived on France’s culinary scene in the 1920s.

4. POTATOES

Historical records show that potatoes reached Ireland by the year 1600. Nobody knows who first introduced them; the list of potential candidates includes everyone from Sir Walter Raleigh to the Spanish Armada. Regardless, Ireland turned out to be a perfect habitat for the tubers, which hail from the misty slopes of the Andes Mountains in South America. Half a world away, Ireland’s rich soils and rainy climate provided similar conditions—and potatoes thrived there. They also became indispensable. For millennia, the Irish diet had mainly consisted of dairy products, pig meats, and grains, none of which were easy for poor farmers to raise. Potatoes, on the other hand, were inexpensive, easy to grow, required fairly little space, and yielded an abundance of filling carbs. Soon enough, the average Irish peasant was subsisting almost entirely on potatoes, and the magical plant is credited with almost single-handedly triggering an Irish population boom. In 1590, only around 1 million people lived on the island; by 1840, that number had skyrocketed to 8.2 million. Unfortunately, this near-total reliance on potatoes would have dire consequences for the Irish people. In 1845, a disease caused by fungus-like organisms killed off somewhere between one-third and one-half of the country’s potatoes. Roughly a million people died as a result, and almost twice as many left Ireland in a desperate mass exodus. Yet potatoes remained a cornerstone of the Irish diet after the famine ended; in 1899, one magazine reported that citizens were eating an average of four pounds’ worth of them every day. Expatriates also brought their love of potatoes with them to other countries, including the U.S. But by then, the Yanks had already developed a taste for the crop: The oldest record of a permanent potato patch on American soil dates back to 1719. That year, a group of farmers—most likely Scots-Irish immigrants—planted one in the vicinity of modern-day Derry, New Hampshire. From these humble origins, the potato steadily rose in popularity, and by 1796, American cookbooks were praising its “universal use, profit, and easy acquirement.”

5. CORN

Corn growing in a field

In the 1930s, geneticist George W. Beadle exposed a vital clue about how corn—also known as maize—came into existence. A future Nobel Prize winner, Beadle demonstrated that the chromosomes found in everyday corn bear a striking resemblance to those of a Mexican grass called teosinte. At first glance, teosinte may not look very corn-like. Although it does have kernels, these are few in number and encased in tough shells that can easily chip a human tooth. Nonetheless, years of work allowed Beadle to prove beyond a shadow of a doubt that corn was descended from teosinte. Today, genetic and archaeological data suggests that humans began the slow process of converting this grass into corn around 8700 years ago in southwestern Mexico. If you're wondering why early farmers showed any interest in cultivating teosinte to begin with, while the plant is fairly unappetizing in its natural state, it does have a few key attributes. One of these is the ability to produce popcorn: If held over an open fire, the kernels will “pop” just as our favorite movie theater treat does today. It might have been this very quality that inspired ancient horticulturalists to tinker around with teosinte—and eventually turn it into corn

BONUS: TEA

The United Kingdom’s ongoing love affair with this hot drink began somewhat recently. Tea—which is probably of Chinese origin—didn’t appear in Britain until the 1600s. Initially, the beverage was seen as an exotic curiosity with possible health benefits. Shipping costs and tariffs put a hefty price tag on tea, rendering it quite inaccessible to the lower classes. Even within England’s most affluent circles, tea didn’t really catch on until King Charles II married Princess Catherine of Braganza. By the time they tied the knot in 1662, tea-drinking was an established pastime among the elite in her native Portugal. Once Catherine was crowned Queen, tea became all the rage in her husband’s royal court. From there, its popularity slowly grew over several centuries and eventually transcended socioeconomic class. At present, the average Brit drinks an estimated three and a half cups of tea every day.
