Airwheel – a self-balancing unicycle

Hands up, who’s ever heard of an Airwheel? Okay a few of you at the back… oh no you’re just scratching your heads.

Okay, take a look at this.

What most people think of when you talk about unicycles

I am of course referring to the ‘gadget’ not the lady who is standing upon it.

That device (or ‘gadget’ as I just referred to it) is called an Airwheel. That’s how I describe mine to people now. Self-balancing motorised unicycle was a bit of a mouthful and it often gave people who hadn’t seen one the wrong idea as to what I was riding – I’m not training to join a circus!

To be precise, the lady in the above picture is standing (well, strictly speaking she is balancing) on an Airwheel X5; a 10kg model with a 500 watt motor and a 14 inch tyre. Airwheel being the brand, X5 the model.

I’ve recently bought myself an Airwheel and as a technology blogger I feel it’s my duty to put it through it’s paces, and then write a review on my findings. That’s not this post though, the review is coming out next Monday. Today my plan is to break you in gently to the Airwheel concept and technology.

Airwheel Brand

As I’ve already mentioned, Airwheel is the brand and there are many different models of Airwheel. They mainly make devices like the one in the picture above (right at the top, not the one of the traditional unicycle!) but they also make a Segway style rover and a skateboard type transporter – called the Airboard.

The model I have bought is a two wheel Airwheel Q3 – also known as the Mars Rover. Strictly speaking having two wheels means it’s not a unicycle – so it’s a bicycle, or a ducycle, but there isn’t any cycling involved so… I don’t really know what it is!

How Does An Airwheel Work?

The model I own – the Airwheel Q3

You may be wondering, what is the technology behind the Airwheel? Well it’s actually reasonably simple.

The computer chip (which is tucked away safe from water and dust in a compartment inside the unit) uses information it gets from its sensors to keep the device level by moving the wheel(s). If the user puts pressure on the unit in a forwards direction (by leaning forwards and pushing their toes towards the floor) the device moves forwards. To slow down they then push down with their heals, which reduces the speed and can even enable you to reverse!

Here is how Andy from Airwheel Direct describes the technology:

“A computer control board constantly monitors the state of the Airwheel and it’s position relative to the ground, it uses this information to control the brushless hub motor and keep the unit upright. Leaning forwards on the foot plates begins to tilt the Airwheel and therefore makes the wheel rotate to keep it underneath your feet, the result being forward motion. Turning is achieved much like a bicycle by leaning left or right. The more you lean, the tighter the turn will be.”

Are They Versatile?

In one word: very! You can travel forwards and backwards on them at up to around 11/12mph. Once you get the hang of it you can travel over grass, gravel and mud, turn in very tight spaces and jump up and down steps and curbs! Want proof? Here is a (bit of a daft) video of me, pushing my Q3 to its limits.

You may be shouting “don’t break it!” at your screen, but don’t worry, it’s pretty durable. I’ve fallen off mine whilst testing the limits several times – no broken bones, yet! – and it still works; like new. As you may have been able to pick up from that video, I’ve covered mine in foam and then Gaffer taped it on. The only reason I have done this is to protect the casing. When I first took it out I fell off once or twice and as the unit fell over it scuffed itself a little. The foam now takes the impact instead – although I seldom fall off nowadays.

That’s it for this article. I will be doing a full review of my experience of the Airwheel Q3 next week and will be deciding is it any good, and if so, is it worth what it costs.

The cost of sending a Samsung emoji

A few months ago, my Galaxy S4 Mini (click this link to go to my series about it) updated to Android KitKat – from Jelly Bean. KitKat was released in 2013, but because Samsung like to fiddle with Android before they roll it out to users – or as I now like to say, apply their Disney layer – kudos to David – it takes a while for their handsets to get the updates.

Apart from a few minor interface changes – some good and some not so good – I didn’t really notice much of a difference with the KitKat upgrade. Some of my icons changed colour, my screen mirroring functionality seemed to stop working and GPS got renamed Location. There were a few other changes but at this moment they escape me.

Oh and how could I forget, that annoying emoji/emoticon button! KitKat added a terribly annoying button to my keyboard, a smiling face, which whenever you accidentally click on it, becomes the default extras button; that’s the lovely little button next to the space key that gives you the option of voice typing, pasting, visiting settings, and now also adding an emoji.

Now I’m not against emoji, some of them are pretty cool… 🙂

…what I am against is Samsung emoji. The super-duper Samsung upgrade to KitKat may have enabled me to send emoji – yay! – but it came at a cost: MMS. If I want to send an emoji, Samsung very kindly converts my text message (an SMS) into an MMS.

This isn’t a problem if you get a large number of MMS messages included in your contract, but most people (at least here in the UK) don’t. I’m not someone who does either, so when I tried to send a message (no bigger than one standard text message) with an emoji in it, I got charged 33 pence by my provider and worst of all the recipient was unable to receive MMS messages, so they didn’t even get to see my 33p text!

The BBC and Money Saving Expert are just two sites that have recently been warning consumers of the hidden costs linked to emoji usage.

Cue Textra.

Textra SMS

iPhone owners don’t suffer the same fate as I did, because Apple’s default messaging application doesn’t treat emotion icons as images. They may take up more than one character, but you can use them in SMS messages. Not wanting to be outdone, I went on the hunt for a better SMS app.

First I tried Google Hangouts. I have never got along very well with Hangouts, but when I started using it for text messages, I didn’t find it quite so bad. I could send emoji as text messages, and I could type as many characters I liked and it would just send multiple SMS messages; Samsung’s default messaging app converts messages larger than three texts into MMS messages too.

After a week or so, Hangouts’ lack of features and general design started to get on my nerves, so I was out on the hunt again for another alternative. After reviewing a handful of very viable alternatives, I decided to give Textra SMS a try.

Textra SMS quick reply

When you get a new text, Textra SMS enables you to reply quickly, without opening the full app.

To put it simple, Textra is fantastic. You can do pretty much everything you can with Samsung’s standard messaging app, and more. You can customise the look and feel, you can send as may characters as you like without it converting into an MMS, and you can send emoji!

One of the awesome features that got me hooked on Textra is the message preview. Say you are browsing the web and you get a text. Texra has the option of a notification which appears at the top of your screen; the notification is basically a message preview. If you ignore it, it disappears after a few seconds, but if you click on it and it opens a small version of the app over the top of whatever you were doing previously. You can type a reply and then as soon as you click send, it disappears and you are back to what you were doing.

If you are looking for an alternative texting app for Android, I would definitely recommend Textra.

What’s in Your Computer (and phone, and WiFi)?

Lenovo

This week the news is full of Lenovo, a computer manufacturer that has been selling machines that they have already fitted with what some call Malware or just Adware. Magic in the machine indeed!

The mal/adware in question is made by a company called “Superfish.” The software is essentially an Internet browser add-on that injects ads onto websites you visit. Details here.

Besides taking up space in your computer, the add-on is also dangerous because it undermines basic computer security protocols.

That’s because it tampers with a widely-used system of official website certificates. That makes it hard for your computer to recognize a fake bank website. This means that you are more likely to give all of your personal data away, let nasty things into your computer, and allow people to monitor your use.

No good I hear you say, and all so that they can feed you adverts while you are browsing.

Hidden Extras?

But this news does bring up another question, what else is in the computer? What else is it programmed to do? The simple answer is that I and probably most of you do not know. We have bought a machine that does the things we want it to do, but who knows what else?

Now as I eat my breakfast, I like to read the ingredients on the side of the packet. It is good for language skills as it is usually in several languages. But can I do this with my computer? You don’t get much in the way of documentation with a $400 laptop. Certainly not considering what is inside it.

So the computer company in question have disabled something at their end and the problem is resolved. But if they tell you that they fixed the problem are you going to believe them? After they did something that put your computer and everything saved on it at risk? Or should you put a new operating system on the new machine, wipe the hard drive and start again?

Why do we trust these manufacturers when they consistently do things that are not in our interest? WiFi providers that con your computer into trusting fake certificates so that they can block certain sites (and read your mail or follow your searches)? Samsung that record your voice through your smart TV and send it non encrypted over the Internet to unnamed third parties, social media sites and search engines that collect your data, mobile phone companies that map your every movement, the list goes on.

So if you cannot trust wifi, or computer manufacturers, or Google, or Facebook, or Samsung to treat our data securely and correctly, who can you trust? And more to the point why are we giving them our lives to play with?
