Five toy drones for beginners


Five toy drones for beginners

Many of us drool over powerful high-flying camera drones or superfast racing quads, but for adults or kids just starting out, a far cheaper toy drone is far more practical.

Made to zip around your living room or backyard for a few minutes at a time, toy drones are a good way to practice your piloting skills without worrying about watching something $500 or much, much more hit the ground or disappear into the trees. They're also a lot of fun to fly -- whether or not you're into RC toys. And, because the tech inside is getting smaller and cheaper, you can find them with more advanced features like GPS for safer, easier piloting and cameras for first-person-view flying (FPV).  

There are plenty to choose from, which is great, but it can also be a bit overwhelming if you've never shopped for a drone before. You can start with our drone buying guide if you're not quite sure what you're looking for or familiarize yourself with some common terminology. Or, if you're just after some quick toy drone suggestions, just read on. 

Keep in mind when you're shopping that flight times on toy drones are typically around 5 to 8 minutes, so if you want to keep flying without charging first, go with a model that uses removable rechargeable batteries. Also, if this is your first toy drone, we recommend going with one that has replacement parts readily available.

Aura Drone with Glove Controller

Absolutely perfect for any age or skill level, the Aura uses hand gestures to control it. Strap the "controller" onto your hand and you tilt your hand up and down to fly it away from you and back again. Tilt to the left to go left and to the right to go right. Press and hold a button under your thumb and the same movements let you raise and lower it or flip it left and right. Level out your hand and it will hover in place. Also, with the props are completely protected, so it just bounces off walls or whatever if you drift off course. 

Currently available for $80 (AU$200 or £100), flying the Aura is a bit like playing with a flying yo-yo. It's so easy to learn, too, that I had my 6-year-old flying it on his own in less than a minute. Which is good because the battery only lasts about 5 minutes, though it is removable and extras are inexpensive.

Recommended for: If you want to fly a drone but get anxious at the thought of the sticks and buttons on a typical remote control. 

Parrot Mambo FPV

Parrot's Mambo quadcopter has a set of pins on top that allow for attachments that include a small cannon, a grabber claw and now a 720p HD camera. The camera can record to a microSD card, but more importantly it lets you pilot by FPV or first-person view by streaming to your phone. 

Parrot's minidrones are designed to make flight easy, especially when flying indoors. However, its autopilot technologies are not something you really want when racing. To that end, Parrot lets you change to a Drift mode that disables the drone's horizontal stabilization and a Racing mode that completely disconnects the autopilot for full manual flight. Plus, diving into the settings lets you adjust all of its directional speeds, so you can learn to FPV race at your own pace. 

The $150 bundle (AU$230 or £125) includes the quad and attachable camera, Parrot's Flypad controller and Cockpitglasses 2 headset for use with a phone running the FreeFlight Mini app. Bonus: The minidrone supports Tynker and Swift Playgrounds coding platforms designed to teach STEM skills to kids.

Recommended for: Taking the sting (and expense) out of learning to fly a racing drone.

PowerUp FPV Paper Airplane

PowerUp

PowerUp has made several app-controlled paper airplane systems like its newest, the Dart, a powered paper airplane that does flips and rolls. The PowerUp FPV is its first to add a camera for live-streaming video to your phone, which you can place in a VR headset like Google Cardboard. Not only to you get a pilot's view from the plane, but you can control it just by tilting your head. 

Because it's a plane, it can turn on a dime or start flying sideways like a quadcopter, so you're going to want a lot of space to fly this. But if you've here's your chance. It's $140 for the kit (AU$170 or £100) which includes everything you need except a phone, but right now you can get it for $100.

Recommended for: Anyone who ever dreamed of actually flying on a paper airplane or just wants something different that'll let you prove people wrong when they say, "There's no way that thing'll stay in the air."

Syma X5C

Sarah Tew/CNET

At around $40 (AU$50 or £35) the 5XC is one of the least expensive toy drones with a 720p camera. This thing feels pretty cheap and the camera is basically toy-quality, as you might expect for the price, but it flies surprisingly well and can take quite a lot of crashing. It won't hold its altitude on its own, but that makes it great for learning how to actually control the drone's throttle. 

Battery life comes in at about 7 to 10 minutes, but extra batteries as well as replacement parts are easy to come by, and the manual even gives you an assembly breakdown. It's available at Amazon.

Recommend for: Learning how to pilot -- and repair -- a quadcopter. This is a simple, ready-to-fly toy with a camera that flies better than its price suggests.

Sky Viper V2450GPS

Josh Goldman/CNET

One of the technologies that makes pricier drones more stable and easier to fly is GPS. With it, a drone can use satellites to help it know where it is in space, so it can just stop and hover in place if you let go of the sticks. It can also allow the drone to return to where it took off from with the press of a button or if its battery starts to get too low. And that's exactly what you're getting with the Sky Viper V2450GPS.

The 720p HD camera drone sells for less than $150 ( AU$179 or £100) that can live stream to your phone, capture photos or video to a microSD card and gives you the stability and safety of GPS. Its battery will get you around 10 minutes in the air and extras are about $8 each. 

Recommended for: Beginners or more advanced pilots who want the stability and convenience of GPS in a quick and nimble quadcopter with a camera at a rock-bottom price.

Substack Debuts iOS App for Reading Newsletters

Substack has just unveiled its first mobile app, which operates like an RSS reader for Substack writers.

Launched in 2017, Substack provides a publishing platform for monetizable newsletters covering a variety of topics, including politics, tech, finance, culture, parenting, music, comics and food.

Instead of scrolling through their email inbox, users of the Substack Reader app can access a feed of the newsletters they follow, available in a reader view with comments included.

Followers get notifications when new installments are available, and can tap into an author's related content, including podcasts and videos. They also receive recommendations for new authors.

Substack writers benefit, too, the company said, with reliable delivery and "multiple media formats in a single package."

In a series of tweets Wednesday morning, Substack co-founder Hamish McKenzie compared the new app to the dearly departed Google Reader, the RSS reader that shuttered in July 2013.

"I remember how good it felt to be a thinking person who liked to read on the internet," wrote McKenzie, a former journalist. "I remember being able to follow my favorite writers and read them at length, where their arguments could be made calmly, where there was a point in aiming for beauty."

Hearkening back to "the time before we gave up our minds for dopamine hits," McKenzie said the Substack app "makes me feel like a reader again."

The Substack Reader is currently only available in the Apple App Store. A representative told CNET a waiting list is available for those who want to be notified when the Android version launches.

GM's 1,000 hp 632 cubic-inch crate engine is its largest and most powerful ever

They say that when it comes to making power and torque, there is no replacement for displacement. While that's slightly less true these days with super-efficient turbocharged engines and EVs, the folks at General Motors are holding fast to that ideology with their latest crate engine, the ZZ632/1000, which clocks in at a whopping 632 cubic inches of displacement and which was announced on Wednesday.

For those of you not accustomed to working in old money, that's 10.36 liters. For comparison's sake, the utterly massive Dodge Viper engine only weighed in at 8.4 liters and with two more cylinders. As its somewhat unwieldy name suggests, the 632-cubic-inch crate engine produces a whopping 1,004 naturally aspirated horsepower. It also makes 876 pound-feet of torque, and it does both on 93-octane pump gas.

Apart from its displacement, there are a few notable features that make the ZZ632 special. Chief among these are the aluminum RS-X symmetrical port cylinder heads, which, unlike many previous big block head designs, have identically sized intake and exhaust ports for each cylinder, which helps ensure that all the engine's eight cylinders produce the same power.

The ZZ632 shares its block architecture with GM's only slightly less elephantine ZZ572 crate engine but features a bore that's been increased by 0.040-inch. The engine's stroke has also been lengthened over the ZZ572's by 0.375-inch, which accounts for the bulk of the displacement increase. The engine also features forged steel connecting rods and crankshaft, which helps with engine longevity. GM claims that the ZZ632 withstood 200 simulated dragstrip passes without issue.

Unlike some of its other high-performance crate engine offerings, GM isn't placing a cap on ZZ632 production, and, in even better news for speed freaks, the engines will be kept in stock rather than being built to order. We don't have pricing yet for this monster of an engine, but we suspect it will land somewhere north of the approximately $16,300 that is being charged for the ZZ572.

How to tell if your child has sleep apnea my child has sleep apnea sleep apnea and child behavior how to help child with sleep apnea does your child have a 504 does your child have add does your heart stop when you sneeze does your period stop in water does your chewing gum lose it s flavor song does your mother know chords
Does your child have sleep apnea? How to tell and what to do


Does your child have sleep apnea? How to tell and what to do

Pediatric sleep apnea is relatively common, affecting from 1 to 4% of kids. Like adults, children with obstructive sleep apnea experience breathing interruptions while sleeping because the muscles in their airways collapse, leading to daytime sleepiness or potential behavioral issues. In the long term, if left untreated, sleep apnea in kids can cause serious health complications like stunted growth or heart issues.  

The good news is that symptoms are pretty mild for most children, and they often outgrow it. Here's what you need to know if you suspect your child might have sleep apnea.

What causes sleep apnea in children? 

There are two main types of sleep apnea in kids -- obstructive sleep apnea and central sleep apnea. With obstructive sleep apnea, the muscles in the airway collapse in on themselves, blocking your child's ability to breathe. Central sleep apnea is when the brain isn't sending the correct signals to the airway muscles.  

We will talk primarily about obstructive sleep apnea, as it is more common than central sleep apnea. There are several causes of sleep apnea in children, like narrow facial bone structures, cleft palate or a high or low muscle tone. 

However, two main factors largely contribute to OSA in children.

Obesity

According to a cross-sectional study of children aged seven to 18, obesity is a significant contributor to sleep apnea. About 44% of children categorized as overweight had OSA compared to 9.1% prevalence in the "normal-weight group." 

Like in adults, obesity is one of the leading risk factors for sleep apnea. It happens because fat deposits collect in the upper respiratory tract, limiting muscle activity. 

Enlarged tonsils and adenoids

Sleep apnea can arise in children because of enlarged tonsils or adenoids. The tonsils are found in the back of the throat and the adenoids in the nasal cavity. If either is enlarged, it can narrow the child's airways, making it difficult for them to breathe while sleeping. The severity of the breathing interruption will depend on the side of the tonsils or adenoids. This doesn't happen to all children, and it's not exactly clear why it happens to some and not others. Exposure to viruses, bacteria or other infections can enlarge tonsils or adenoids. 

Common signs and symptoms of sleep apnea in kids

Your child likely won't be able to tell you what's happening. Generally speaking, they'll fall asleep after any breathing interruptions without knowing they woke up. If your child complains of being tired during the day or their behavior has changed, it's worth noting what happens when they sleep.

Snoring isn't always necessary to diagnose a child with sleep apnea, though it is the most common indicator. However, there are several other signs.

The signs of sleep apnea in kids include:

  • Snoring and gasping for breath at night
  • Mouth breathing or heavy breathing
  • Nighttime sweating
  • Wetting the bed
  • Sleepwalking or night terrors
  • Restless sleep
  • Trouble waking or staying awake
  • Behavioral issues

What happens if pediatric sleep apnea isn't treated?

Just because your child snores it doesn't mean they have sleep apnea. If you suspect they could have it, it's worth looking into. The effects of untreated sleep apnea can be severe -- high blood pressure, the risk of a stroke and heart issues all increase with sleep apnea. 

There are differences between sleep apnea in adults and children -- most of which are highlighted in the side effects of the disorder. Children with sleep apnea will likely exhibit behavioral problems due to their fractured sleep patterns. They may have trouble waking up in the morning, paying attention in school or being hyperactive. If the sleep apnea is left untreated, your child may experience behavioral and learning difficulties.

Treatments for pediatric sleep apnea

After a physical exam and detailed sleep history, a sleep study is best to diagnose pediatric sleep apnea. In a pediatric sleep study, your child's sleep will be monitored in a lab setting where a doctor can note any abnormalities of sleep apnea symptoms. 

Once diagnosed, your child's sleep apnea treatment will typically fall within these three categories. However, special cases may require unique treatment options. 

Surgery

One of the most significant contributing factors to childhood sleep apnea is the enlargement of the tonsils or the adenoids. Your ears, nose and throat doctor may recommend removing one or both to effectively cure obstructive sleep apnea -- surgery results in the elimination of sleep apnea symptoms 70 to 90% of the time. 

After surgery, you should expect a sore throat. Children with sleep apnea who get their tonsils and adenoids out have a higher chance of lower oxygen levels for the first two to three nights after surgery.

Continuous positive airway pressure machine

Your child's doctor may also recommend using a CPAP machine to treat their sleep apnea. CPAP machines constantly blow air into your child's airway, ensuring it doesn't close during the night. While they effectively treat sleep apnea, they do require that your child wear the mask when they sleep. 

Sleeping with a CPAP machine will be an adjustment. We recommend that you slowly introduce the machine. Try it at nap time at first and then for more extended periods each night. This will help them ease into the change and better adapt. 

If your child cannot tolerate a CPAP machine, your doctor may recommend an oral appliance to treat their sleep apnea, which pushes the tongue and jaw forward, expanding their airway through the night. Oral appliances are less effective but are easier for most children to adapt to. This option is generally limited to those who had surgery to remove their tonsils and adenoids, and the sleep apnea persists. 

Diet change

In addition to other treatment options for sleep apnea, lifestyle changes will be recommended for children who are considered overweight. Research has shown that weight loss successfully treats sleep apnea among children. Talk to your doctor about a nutritional and exercise plan that promotes a healthy way to lose weight.

Remember that adequate sleep is a crucial part of weight management. Kids who aren't getting enough sleep have a higher likelihood of gaining weight. A CPAP machine can help give them more restorative sleep to help with weight loss

When should your child see a doctor?

The big, lingering question you have is probably: what should I do first if I think my child has sleep apnea? 

In general, you shouldn't try to self-diagnose your child's sleep apnea. If your child consistently presents any of the symptoms associated with sleep apnea -- snoring, gasping for air or restless sleeping -- you should consult a doctor. It's never too soon to start the conversation. 

Tips to prepare for your appointment:

  • Make sure you bring all the questions you want to be answered. Don't shy away from talking through everything on your mind. 
  • Be ready to explore treatment options you're comfortable with. Express your concerns and hesitations.
  • If you're seeking additional support, you can connect with your local A.W.A.K.E group, an education and support group run by the American Sleep Apnea Association.

Acer's Predator gaming monitors come for your wallet, while laptops get the latest updates


Acer's Predator gaming monitors come for your wallet, while laptops get the latest updates

This story is part of CES, where CNET covers the latest news on the most incredible tech coming soon.

Three new monitors stand out from Acer's crowd of gaming gear at CES 2022. Not as yowza as Alienware's QD-OLED debut, but with enough yes-I-may-want-it newness for the gamer who's OK spending $1,799 or more for a fast 32-inch 4K HDR monitor or $2,499 for a 48-inch OLED to pair with an Xbox Series X or PS5.

The veteran Predator X32 line welcomes two new members this year -- the, well, Predator X32 and Predator X32 FP. They use the same IPS panel, a DisplayHDR-1000 certified 4K screen with a peak brightness of 1,200 nits and full coverage of the Adobe RGB color gamut and 1ms response time. A new 576-zone Mini LED backlight supplants older versions which had a lot more zones but also tended to generate a lot of heat. They also sport a thin bezel design and minimalist stand.

As the names might imply, though, they differ by some supplementary features. The $1,799 X32 FP uses FreeSync Pro for its variable refresh rate support, and its maximum native refresh rate is 160Hz, or 165Hz overclocked. The $1,999 X32 uses G-Sync Ultimate, which adds to the price and supplies support for Nvidia Reflex latency optimization technology, but G-Sync only works over DisplayPort. Its maximum refresh rate over DP is 160Hz, but over HDMI it's only 120Hz. And unless the specs I'm looking at are wrong, which is quite possible, the X32 only offers HDMI 2.0 connections (three of them) while the cheaper FreeSync model has four HDMI 2.1 connectors as well as a USB-C port with 90-watt power delivery.

The Predator CG48

Acer

The $2,499 Predator CG48 console monitor should offer all the usual benefits of OLED -- a large color gamut, high contrast and fast pixel response -- with a refresh rate of 138Hz in 4K. But seems like it might make some sacrifices. For instance, it's not clear how well it will handle HDR: Acer provides what sounds like a low peak brightness of 450 nits (and a native brightness of 135 nits, which is low) and says it supports HDR10, which means it can decode the stream but won't necessarily display it well.

It does have an HDMI 2.1 connection as well as 3 HDMI 2.0 and a USB hub, though it's odd that the USB-C can only charge up to 65 watts.

All the monitors will ship around October.

Acer also brought forth refreshes of its Nitro 5, Triton 500 SE and Predator Helios 300, but nothing really makes them stand out from the crowd on paper. They've all had minor makeovers to tone down the gaming vibe (but just a bit) and the Triton has slimmed down. The Triton will be marketed as a creator-focused laptop in some regions, so a more subtle style is warranted. 

All get the usual upgrades to the newest versions of whichever processor and graphics card they use. That means the Nitro gets 12th-gen Intel Core H and AMD Ryzen 6000 H models, along with all the perks of the new platforms like support for DDR5.

  • The Acer Nitro 5 with Intel ships in March starting at $1,050 for the 15-inch and April starting at $1,100 for the 17-inch; with AMD the 15-inch ships in April starting at $1,100 and the 17-inch ships in May starting at $1,150

No Filters Allowed: This Up-and-Coming Social Media App Aims for Authenticity

BeReal is a social media app that aims to leave behind artificial glamour and give you a more authentic way to tell your stories. Instead of carefully curated images, BeReal offers "a new and unique way to discover who your friends really are in their daily life," according to the company. 

BeReal users post a picture, called a "BeReal," within a random two-minute window each day from wherever they are, doing whatever they're doing. So you probably won't see glossy, stylized photos that have been edited to hell and back. You'll more likely see your friend hanging out on the couch with their dog or cat. 

The app notifies you at the beginning of the two-minute posting window, but since the window changes daily, you can't plan what you'll be doing ahead of time. During that window, you'll snap a picture with both your front and back cameras, and the two photos are uploaded to the app simultaneously.

If you're sitting in your bed, then you'll show off your bedhead. If you're picking up food at a drive-thru, ask if the drive-thru employee wants in on the pic. If you're on the toilet... well, you get the idea. 

Founded in 2019, BeReal has been installed on about 7.5 million devices, according to Apptopia. Here's what to know about the app, including what you can and can't do.

Can I edit BeReal photos?

No. You can't spruce up your BeReal by brightening, cropping or using weird filters as you might on other social media apps. If you have bags under your eyes, then you have bags under your eyes in the post. That means you won't be subjected to heavily edited and staged photos of your friends acting as if they have a glamorous lifestyle. You can retake a photo, but the app shows people how many times you retook the picture once you post your BeReal. 

What happens if I miss the two-minute window?

If you don't post in the allotted two minutes, nothing really happens. There's no Snapchat-style streak to lose, and you can still post later. But BeReal snitches on you and tells people you posted "late." BeReal sends out push notifications each time a person posts, so your friends will know how late you posted. That sounds a little stressful in itself.

What if I don't want to post?

That's fine. You don't have to post, but then you won't be able to see other people's posts. You must actively participate in the app to see what everyone else is doing. By requiring people to post in order to see other people's posts, it ensures everyone plays along. 

You can't see posts on BeReal until you post.

Zach McAuliffe/CNET

Who sees my BeReal?

When you post your BeReal, you can either send it only to your friends or you can post it publicly and let anyone on the app see it. When you post publicly, users can find your BeReal in the app's Discovery tab. 

How do I add friends?

People choose a username when they sign up for the app, so you'll have to search for other people's usernames. You can grant the app access to your contacts when you first sign up to quickly find people you know that are already using the app. You can also find and add friends in the Discovery tab. 

Can I post my BeReal on Instagram?

You can if you want. You can see all your posted BeReals in Your Memories by tapping on your profile icon in the top-right corner, and a calendar will show your BeReals listed in chronological order. Just tap the BeReal you want, then share it on other social media or save it to your photos. (BeReal will first ask permission to access an outside app or your photos gallery.) If you want to share your BeReal on Instagram, it uploads to your Instagram Stories, and you can't edit the picture beyond adding text or a sticker.

As you post, your BeReals can be seen in Your Memories.

Zach McAuliffe/CNET

What else makes BeReal different from other social media?

Let's say you want to respond to a BeReal from a friend with a thumbs-up or a laughing face the way you would on other social media platforms. In order to do that, you have to create a "RealMoji," or a picture of you doing the corresponding emoji. So instead of just adding a pictogram of a thumbs-up, you have to send a photo of you with the gesture. If you want to convey to a friend that their BeReal was funny, snap a photo of your face appearing to laugh.

You can download BeReal for free in the Apple App Store or the Google Play Store.

TikTok Adds Avatars Similar to Apple's Memoji

TikTok users can now animate themselves with the app's latest feature, TikTok Avatars, the short-form video platform said Tuesday. The new feature is similar to Apple's Memoji, which let you personalize your avatar, send your avatar as a sticker and record videos as your avatar to send to friends.

"We're excited to launch the first version of TikTok Avatars globally and will continue to improve and innovate to make sure the experience is truly representative of all who are on TikTok," the company said in a statement.

Users can show off their individuality by choosing different hairstyles, piercings, accessories and more for their avatars. TikTok also said it is working with its Creative Diversity Collective to be more inclusive and representative of the TikTok community.

"From outfits to skin tones and hair color down to texture, building inclusive features and experiences remains our priority," the company said. "We'll continue to listen to our community and look to creators for feedback at every step of its development."

TikTok Avatars are available to all TikTok users. The feature can be found in the effects section of the app by searching for the Avatar effect. Once you've made your avatar, you can start recording and sharing videos.
