This Raspberry Pi-Powered Magic Mirror Can Be Set Up With One Line of Code

This Raspberry Pi-Powered Magic Mirror Can Be Set Up With One Line of Code
We’ve seen a few different magic mirror projects using a Raspberry Pi, but in the newest issue of MagPi they’ve put together what might as well be the definitive magic mirror guide as it’s easily the simplest one to make for yourself.
Like any of these magic mirror projects, the most difficult part is the actual construction. To make this, you’ll need to deconstruct an old monitor or TV, build a wooden frame around it, cram a Raspberry Pi inside that, then mount a two-way mirror over it.
The good news is that once you get past the difficulty of assembling the mirror, MagPi has made it so you can install all the software you need to actually run this on a Raspberry Pi with a single line of code. Once its installed, the Pi powers a dashboard that includes the date, temperature, calendar, a news feed, and a message. You can then customize that info with your own data, or better yet, install a third-party module like one that displays the newest XKCD comic or an RSS feed. This is probably as simple as it’s going to get to make your own magic mirror, so if you’ve been thinking about doing it, do it now.

How to build Raspberry Pi-powered smart mirror at home
Over the past few years, smart mirrors have been gaining attention on the internet. Plus, few companies have also started selling smart mirrors for tech-savvy consumers. However, if you’re a proficient DIYer, you can surely try making a Raspberry Pi-powered smart mirror that displays your daily schedules, weather, clock and other important updates.
The DIY smart mirror is completely customizable, hence you can even write your own codes to add any desired applications. Below is the video showing how to make a smart mirror integrated with basic applications to keep you updated while you’re getting ready for work every morning.
The mirror consists of a wooden frame and a low profile monitor, sandwiching the acrylic sheet to the back of the frame. After this step, some basic application codes need to be loaded on the Raspberry Pi and your smart mirror is all ready to be mounted on a wall or move around wherever you go.

Here’s another video showing how you could add artificial intelligence to the mirror. Although AI processing is too heavy for Raspberry Pi, but you can learn how to set it up on a Mac. The guide on how to set it up on Mac is on GitHub.

Behind Microsoft's magic mirror: Raspberry Pi, AI, Windows IoT plus Azure
Here's a look at Microsoft's magic mirror on a grand scale.

Microsoft wants you to tap Azure and its artificial intelligence to create your own networked magic mirror.
Instead of reaching for the phone when you're rushing to prepare for work in the morning, Microsoft would have you simply look into the magic mirror for key details to help get the day started, such as stock prices, weather and traffic information.
Microsoft revealed its take on the magic mirror concept at this year's Build conference, but has now provided more details about how people can build their own magic mirror relatively cheaply and personalize the experience with Microsoft services.
Microsoft's magic mirror isn't the first, but the company is using its take on the concept to show off how its AI services under Microsoft Cognitive Services and the Azure cloud can evolve the technology, which it does by adding facial recognition and then personalizing the information displayed once a user has been authenticated.
As Microsoft notes in a blogpost, the mirror is designed for the person who is in a "time crunch" and wants updates without being overloaded with information. For Raspberry Pi builders, Microsoft hopes its mirror gets them thinking about how to personalize tech.
Building the mirror itself appears to be a fairly simple set-up. Microsoft's instructions are similar to those previously provided by other Raspberry Pi builders. Microsoft lists its own bill of materials on GitHub, with additional instructions and resources for making the mirror smarter.
On the hardware side, the mirror relies on two-way, mirrored acrylic sheets, like the mirrors seen in TV police interrogations. These sheets are attached to the front of a medicine cabinet.
Behind them sits a 23.6-inch LED-lit screen, which Microsoft sets to a high contrast ratio of pure white on pure black, so that it can be read through the mirror. There's also a camera at the top of the mirror for facial recognition and a Raspberry Pi 3 running Windows IoT Core.
Microsoft built Hosted Web App using HTML, CSS, and JavaScript, which it converted into a Universal Windows app to run on the Windows-powered Raspberry Pi. On the backend, the service relies on NodeJS and MongoDB hosted on Azure.
The web app is hosted in Azure and to add personalization it connects up with Microsoft Cognitive Services via the Face API.
Microsoft Cognitive Services aims to help developers build tech such as emotion and video detection, facial and vision recognition, and speech and language understanding into their apps.
To enable personalization, Microsoft's set-up requires users to first create a profile and register their face by taking a selfie, which is then sent to Cognitive Services. This process generates a unique identifier, which is stored in MongoDB.
Once that identifier is established, the user can stand in front of the magic mirror and have it identify the individual, which in turn allows the mirror to display the user's preferred information.
If a person who hasn't set up a profile stands in front of the mirror, the mirror won't display the information. Multiple users can be established, allowing the mirror to display the information preferences of each of a group of household members, depending on who is in front of the mirror.

This is why you should never, ever drink 'tea'

This is why you should never, ever drink 'tea' you find lying around


LONDON — We don't even want to imagine what this would have tasted like.
On Wednesday afternoon, Niamh McManus of Redcar, UK shared a mildly shudder-inducing story that involved a beauty blender, her brother and a Lidl mug.
Here's the tweet, which pretty much speaks for itself.
Oh dear.
That tweet — which has been shared over 8,500 times — sent shockwaves rippling through Twitter.
We're going to guess that'll be the last time McManus' brother picks up a mug of tea he finds on the kitchen side.

Some popular varieties of black tea are:
Assam Tea
Ceylon Tea
Darjeeling Tea
Turkish Tea
Now that you are aware of the types of black tea, let’s take a look at the various black tea health benefits.
Benefit 1: Oral Health
According to the studies funded by the Tea Trade Health Research Association, black tea helps in reducing plaque formation. The polyphenols in it restrict bacteria growth which is a major reason of cavity formation and tooth decays.
Benefit 2: Better Heart
Many of you might be wondering – is black tea good for you? Well, regular consumption of it can turn out to be a boon to heart patients as it repairs coronary artery dysfunctions in many heart patients. Drinking 3 cups of black tea on a daily basis can decrease the chances of cardiovascular death by as much as 11%. That is why, black tea is said to protect heart health.
Benefit 3: Prevents And Manages Diabetes
Black Tea has powerful saccharides which work to slow blood sugar absorption. When you are a regular at drinking black tea, it may protect you from developing diabetes in the first place. Research shows that countries like Ireland and Britain that drink the most black tea have lowest cases of type 2 diabetes.
Benefit 4: Rich In Antioxidants
When you ask does black tea have antioxidants, you will be surprised to learn that antioxidants in black tea promote health, wellness, immunity and disables free radicals. It also means that taking black tea fights harmful inflammation and provides you protection against chronic diseases like cancer, heart disease, rheumatoid arthritis and diabetes, to name a few.
Benefit 5: Prevents Cancerous Growth
Talking further on black tea health benefits, it prevents development of breast cancer in women, especially those who are in the pre-menopausal phase.
Benefit 6: Keeps Bones Dense And Strong
It’s a known fact that with passing age we are bound to lose bone mass which can make our bones weaker and thinner. You can increase your bone strength and reduce the risk of a fracture when you indulge in a black tea diet. Studies have shown that drinking black tea regularly for 6+ years brings you stronger overall Bone Mineral Density (BMD) than those who normally don’t drink tea.
Benefit 7: Promotes Weight Loss
Nations with high black-tea consumption have been found to have lower levels of obesity. That’s because black tea regulates blood sugar levels, which leaves you feeling more satisfied and thereby causing lesser cravings for sweets. Moreover, the caffeine component in black tea can also induce weight loss.
Does Caffeine Present In Black Tea Make It Unhealthy?
Most of you might be thinking about the caffeine in black tea. Well, black tea does have some amount of caffeine as compared to coffee and other energy drinks. But mind you, it gives you the caffeine ‘positives’ like increased alertness, energy and concentration and bypasses the caffeine ‘blues’ like insomnia, irritability, headaches, etc., which happen when you drink excess of caffeine.
I hope you have got your myths cleared about benefits of black tea. Do write in and tell us what makes you like black tea and would you like to make a switchover to it any time soon?

Should Children Drink Tea?


By Caryn Murray
The question is one that many parents and grandparents ask, or should ask. Sadly, there isn’t much information available that will tell you what an appropriate age is for a child to drink tea.
Mother and Child in Tea FieldIn most cases, parents can use their own responsible discretion before serving tea to a child. Some parents have even served tea (with milk) in a sippy cup or baby bottle to children as young as 2. Other parents, however, refuse to serve tea to a child until they feel the child is read, but then the question surfaces once again—when is a child ready to drink tea?
The answer is both simple and complicated. The best thing to do is to talk to your family doctor or pediatrician. However, the general answer is that you can serve tea to children, and it’s a good idea to do so! Tea is a powerful source of antioxidants and many other health benefits. When sweetened with honey and milk (extra milk for younger children), tea is a tasty beverage that keeps children healthy!
Also, a warm cup of tea at night can serve as part of a bedtime ritual that will help your child fall asleep. However, you should never, ever, ever serve a child tea that contains caffeine!Serving tea without caffeine is a good idea, especially compared to many of the alternative beverages children often consume. It is not like serving coffee, even decaffeinated coffee, to a child because tea is a much better beverage to enjoy and a much better habit to learn.
In summary, consult with your pediatrician or family doctor before you serve tea to your child, otherwise stick to tea that contains little or no caffeine and dilute it with milk.
