The new Raspberry Pi 2 was announced today promising enough of a performance boost to make it ‘the second PC in the house’.

The credit-card sized computer debuted in 2012 and has since been embraced by schools, maker communities, industrial automation engineers and even the UK Space programme.

At today’s launch event its creator Eben Upton revealed a ripened Raspberry Pi with a quad-core ARMv7 processor and 1 GB RAM, claiming 6 times the speed of the previous B+ model.

This improved performance opens the door to a range of additional applications in schools and industry, as well as in the home.

Its in-home credentials may have been further boosted by the announcement that the Pi 2 will support both Ubuntu Linux and, thanks to a 6-month collaboration with Microsoft, Windows 10.

However, exactly what you’ll be able to do with a Windows-powered Pi isn’t entirely clear, even whether it will include a desktop user interface.

Speaking to Computer Weekly, Upton confirmed that the version of Windows 10 that Microsoft is to make available for free would be an IoT edition “more like what Microsoft did for Galileo [an Intel-based Arduino-compatible developer board].

Microsoft has yet to make a statement about its exact capabilities, we don’t want to create an unjustified impression as to what capabilities it’s going to have.”

Despite the power-up the Raspberry Pi 2 maintains full compatibility with previous versions, sporting the same credit-card form factor and, importantly, the bank-card friendly price.

Since its release total sales of the maker machine have topped 4.5 million, and Upton anticipates a further three million units will ship this year alone. Not a bad return when initial sales projections for the Raspberry Pi were in the ‘tens of thousands’ range.

The Raspberry Pi 2 goes on sale today priced £24.94 + VAT.

Planet of the Apps, Ginx TV

Planet of the Apps, Season 3

Earlier this year I joined the presenting team of TV’s top mobile technology show, Planet of the Apps.

Planet of the Apps, Ginx TVCo-hosted by Adam Savage and Lucy HedgesPlanet of the Apps is now into its third season. Described as the essential guide to everything mobile it covers apps, accessories and everything in between.

So far this series I’ve flown a vintage biplane to test the world’s first wearable smart camera, grappled a 50-foot dragon while wearing Sony’s virtual reality headgear, and wreaked actual havoc with a smartphone-controlled drone.

Flying a vintage biplane (a 1940′s Boeing Stearman) has been one of my personal highlights from the series – here’s a clip:

The final episode of the season broadcasts this Tuesday 18th November at 7.30pm with Adam, Lucy and me sharing our best bits from the year.

It’s been an insane few months making the show, but great working with Adam, Lucy and the rest of the team.

Planet of the Apps is produced in London by Ginx TV, and broadcasts to over 40 territories. In the UK you can watch Planet of the Apps on Virgin Media channel 286.

Technology Expert David McClelland on ITV Good Morning Britain talking Apple iPhone

iCloud Celebrity Photo Hack and Apple Watch on Good Morning Britain

September has been a busy month for television appearances. As well as new seasons of BBC1 Rip Off Britain and Planet of the Apps for Ginx TV, twice I’ve been up bright and early sitting on the ITV Good Morning Britain sofa.

The stories I covered were both Apple-focused but, it’s fair to say, at different ends of the good news spectrum.

First up was the iPhone 6 and 6 plus launch along with the long-awaited announcement of an Apple Watch. Apple product launches are always big news, but this year’s phones were equally big to match.

The ‘iCloud Celebrity Photo Hack’ (or “The Fappening”, as it has also come to be known) is an altogether different news item, made more difficult because there’s a lot that’s still unknown about how private photos of celebrities came to be leaked in the first place – not least, whether Apple’s iCloud is even culpable.

I’ve uploaded my notes on the iCloud Celeb-gate story (do keep in mind that’s exactly what they are, just notes), and I’ll be sure to update them as regularly as I can while the story develops.

How to Keep your Passwords Secure

The new series of Rip Off Britain is well underway, airing on BBC1 throughout September and October.

As usual I’ve been appearing with the team giving expert advice on safe and savvy use of technology and the internet.David McClelland, Tech Expert, BBC Rip Off Britain

It’s been a busy series for me: as well as appearing in the Popup Shop in the West Midlands I’ve been covering a variety of topics including online password security, nuisance call blockers, how online advertising works, and taking care when connecting to public Wi-Fi hotspots.

One item that has generated a lot of interest is online password security.

On average we have 26 online logins each in the UK, with 25-34 years old managing up to 40. Most worrying of all is that Experian, who conducted the research, found that despite the number of accounts we manage, we each use an average of just 5 different passwords!

When researching the item I tried to count how many online accounts I owned: I stopped when I reached 90. I know I’ve many more, and it’s a number that’s only going to grow. I also realised that it’s very rare that I go back to delete an account that I no longer use, particularly if it’s with an online retailer I’ve used just the once to buy a gift.

In the show I ran a workshop in a shopping centre to highlight the challenges of safely managing our online accounts. Of course, it’s a big subject with too much to share in a short item on television, so to help further I put together a leaflet.

My “How to manage and remember your online passwords” leaflet contains tips on how to make your online accounts as safe as possible, including choosing passwords and passphrases that are difficult for fraudsters to guess or crack, and an introduction to password management software. You can download the leaflet from the BBC website.

BBC Rip Off Britain – Season 6

BBC Rip Off Britain 2014The BBC Rip Off Britain Pop Up Shop opened its doors at the Dudley Merry Hill shopping centre in June and once again I was behind the counter serving up healthy slices of consumer advice on all things technology and telecoms.

This is the third season of Rip Off Britain I’ve worked on for the BBC, and after Pop Up Shops in Gateshead and Liverpool I was delighted to rejoin Angela, Gloria, Julia and the team in the Midlands.

Roaming or using your mobile phone abroad was a recurring theme this year as was dealing with nuisance phone calls – in fact I’ve been investigating nuisance call blocker technology for another of this season’s episodes. Among the other items I’ve shot for this series include a film on safe online shopping and another uncovering the ingenuity of online advertising.

This year in Dudley also I ran two public workshops for the show: one on everyday mobile security and safety, revealing how public Wi-Fi hotspots might not be as safe as they seem, and another on how a lock screen passcode still isn’t enough to stop you getting stung if your smartphone gets lost or stolen.

The new series of Rip Off Britain airs on BBC One in September 2014, beginning on Monday the 15th September at 9.15am.

Nokia Lumia 930 Smartphone

Hands-on with the Nokia Lumia 930

Recently I got an early hands-on with the striking new Nokia Lumia 930 smartphone. Writing for Computer Weekly, here were my first impressions:

This article first appeared in Computer Weekly in July 2014, find the original feature here.

Nokia Lumia 930 Hardware

Nokia Lumia 930

The Nokia Lumia 930 is a substantial handset in more ways than one. First up, the body: Nokia has adopted a sturdy aluminium unibody for its latest flagship, but has still chosen to decorate its back with the signature polycarbonate – neon green and orange get the Lumia treatment this season, with white and black completing line-up.

The Lumia 930′s Full HD 5-inch OLED screen is striking too: blacks are black, colours pop and despite the high-gloss it repels greasy fingermarks well, remaining readable even in direct sunlight. The bezel is narrow enough, and the curved edges of the scratch-resistant Gorilla Glass 3 screen lap onto the handset’s chassis, mirroring the contours on the rear.

The volume rocker, power and camera shutter buttons all sit along one side of the handset. This keeps the aesthetic clean but means that securing the 930 into most after-market car kits will result in one or more buttons being permanently depressed. Form 1, Function 0.

Beneath the vibrant exterior sits a quad-core 2.2 GHz Qualcomm Snapdragon 800 chipset, 2 GB RAM and 32 GB storage. While the CPU is last-year’s model it’s certainly no slouch. Despite the missing MicroSD card slot Microsoft now bundles 15 GB of OneDrivecloud storage for free, and 1 TB if you’ve an Office 365 account.

Battery and Wireless Charging

As with other unibody handsets the 930′s battery isn’t removable, although I found the 2420 mAh unit lasted through the day.

Having toyed with wireless charging on the Lumia 920, Nokia once again integrates the feature and this time includes an induction charger in the retail box.

Disappointingly, I found it a bit flaky. On more than one occasion I left the handset atop the charger to find it hadn’t charged the phone. Software bugs need to be ironed out too, with the 930 insisting it was still charging hours after its removal from the charger.

Wireless charging is seen as a panacea by some but until reliability is improved many might still prefer the reassurance of a cable over the questionable convenience of a mat.

Also worth pointing out is that the chassis can get very, very hot on charge or in use.


Nokia Lumia 930 Pureview CameraThe Lumia 930 features a terrific 20-megapixel PureView camera which makes shallow depth of field shots look natural without any clunky software processing. Optical image stabilisation, ZEISS 6-lens optics, dual-LED flash and lossless zoom top out the specs, but again the Lumia’s screen steals the show, making pictures pop like a print.


Windows Phone 8.1 is the newest version of Microsoft’s mobile operating system introducing features which many hoped might bring it in line with its competitors.

Action Centre apes the notification bars seen in Android and iOS. A swipe from the top of the screen recalls missed messages, a customisable quick menu and a shortcut to the phone’s main settings. A welcome addition to the operating system.

Swipe-style typing also debuts and, once you’ve the hang of it, is very accurate. However, Cortana, Windows Phone’s answer to Siri, hasn’t made it onto UK handsets yet – expect to see it (her?) on Windows Phones by the end of the year.

Email and Productivity Apps

Nokia Lumia 930For many email will be a main driver and Microsoft makes setting up accounts simple. I didn’t get the chance to try the 930 with an Exchange mailbox, but it handled multiple outlook.com, IMAP, Gmail and POP mailboxes with aplomb.

Windows Phone 8 also does some useful things around the concept of the unified inbox. Instead of a single inbox encompassing all configured accounts, individual email accounts can be grouped or ‘linked’ together. This makes it possible to combine work email addresses into one unified inbox and personal accounts into another, each accessible through its own live tile.

Lumia_930_10-thumb-250x374-140384The bundled Bing News and Bing Sport apps are intuitive and well designed pulling news from a variety of credible sources. Fundamentally, for a news app to succeed it needs to leave me feeling as if I’ve caught up – these do exactly that, with style, and allow custom feeds too.

Microsoft Office connects you with documents stored on your OneDrive or Office 365 cloud as well as with email attachments. Excel, Powerpoint and Word are well executed apps, although losing what feels like two-thirds of the display to the over-sized on-screen keyboard is a shame.

Windows Phone UI

Microsoft’s spartan UI works hard to differentiate itself from its identikit competitors and, in general, it works well. However, for the sake of productivity I’d prefer to see more actual content on the screen.

A case in point is the official Twitter app – even with the smallest font I can see no more than three or four tweets per screen; similarly, the email app reveals up to six messages before scrolling. At 5 inches and 1920 vertical pixels there’s a lot of screen real estate on the Lumia but the important apps just don’t seem to fill enough of it.


Despite the ’80s-styling on the rear the Nokia Lumia 930 is Windows Phone’s most mature handset to date.

Its productivity credentials are top notch, and OS integration with Microsoft cloud apps and services mean it’s a capable business workhorse as well as a fun down-time device.

All the Windows Phone ecosystem needs now is more apps, and with high-quality handsets such as this they’ll be sure to follow.

Audi quattro - The Power of Four

Audi Quattro – The Power of Four

Vorsprung durch Technik. Audi’s celebrated motto translates as Progress through Technology. Funnily enough it’s a vision I relate to.

Audi quattro - The Power of Four

Over the last few months I’ve been working with Audi on a series of films to showcase just how progressive their technology is.

The Power of Four is one of my favourites. Shot at the MIRA secure vehicle testing facility in Nuneaton we assembled a handful of high-end Audis, an award-winning precision driver and a super slow-motion camera, and drove the cars over treacherous road surfaces to show how quattro all-wheel drive helps when you need it most.

We’ve also just shot a couple of films about the A3 etron and the new Audi TT – I’ll be sure to post those here when they go live.

Hats off to the terrific team at Vertical Productions in London who produce the films for Audi.

Heartbleed Bug

ITV Daybreak: De-mything the Heartbleed Bug

David McClelland ITV Daybreak2014 is seeing internet and online security feature in the mainstream news more than ever before. This week I appeared on ITV Daybreak to help de-myth the Heartbleed Bug.

Here’s what we know about Heartbleed (as of today – it’s a developing story) plus some pointers about what you need to do to protect yourself:

What is the Heartbleed Bug? The Heartbleed Bug (or CVE-2014-0160 to give it its official name) is a vulnerability in OpenSSL, the fundamental bit of code used by as many as 500,000 websites to encrypt the data we send online. The upshot is that sensitive data such as our usernames, passwords and credit card details could potentially have been exposed to hackers. It doesn’t matter what device you’re using to connect to the web – a laptop, Mac, Windows, iPhone or Android – the vulnerability is on the web server that you’re connecting to.

Is it serious? Heartbleed is a serious enough vulnerability that it’s forced website owners all over the world to update, to patch their web servers. And we’re talking about the big players, like Yahoo and its services such as Flickr and Tumblr; some banks and even the FBI’s website are impacted too, an estimated half a million sites in total. Some sites such as Google and Facebook managed to patch their services early on or before the vulnerability was made public, but that doesn’t mean they weren’t vulnerable beforehand. And it’s not just websites that use OpenSSL, it’s email and instant messaging services too.

Who has exploited it? Concerningly, even though the Heartbleed Bug has only just been made public (by researchers at Google and Codenomicon) this vulnerability has been around for a couple of years. Perhaps nobody knew it was there until the last week. Perhaps (and this is speculation) some people did know but, having free access to privileged and sensitive data, chose to keep quiet about it. As it’s difficult to trace if and when the vulnerability has been exploited, we may never know.

What can we do? Some of the knee-jerk advice online has been ‘don’t go to work until you’ve changed all of your passwords’, but that might actually put you at more risk until the affected servers get patched with the fixed version of the OpenSSL code. Good advice is to check whether your service was impacted by the bug - this link on Mashable is pretty comprehensive - and as per the advice change your password only when safe to do so. Whatever you don, don’t use the same password for multiple accounts – consider using a secure password manager to keep track of them all. And, as always, keep a close eye on your bank statements for suspicious transactions.
