Innergie mMini DC10 (review)

The Innergie mMini DC10 is a car 'cigarette' charger. What makes this different to other chargers is that is has 2 USB sockets that allow charging of 2 devices simultaneously.
There's also a nice blue LED between the USB slots showing that there's power.

It can output 5V at 2.1A making it suitable for charging tablets and other devices.

It comes with a cable that has a clever connector, if snapped together it will power an iPhone/iPad through the Apple dock connection, however if the connector is pulled apart, there's also a micro-USB connection suitable for charging non-Apple products. It's also powerful enough to charge a Blackberry device (which lots of other chargers fail to do).

This really is a useful device and has saved the day on many occasions and it actually does manage to produce a full 10W output.

Online prices vary widely, but it can be had for as low as £12 + shipping.

Definitely 10/10

Ofcom makes more spectrum license exempt

Ofcom, the Super regulator that looks after radio spectrum amongst other things, has made more spectrum license exempt.

In the UK there is no such thing as unlicensed spectrum and all devices (whether they broadcast or receive radio transmissions) must be covered by a license as per the Wireless Telegraphy Act. Ofcom can issue a Standard Instrument (really an Act of Parliament) to cover certain frequency bands and uses making that spectrum license exempt, which means if the equipment is used as per the SI, it doesn't need a specific license.

Ofcom has made new spectrum available for SRDs (short range devices) such as range finding equipment for cars. There is now 5MHz of spectrum available between 10.575 to 10.6 GHz which will add to the existing range of 10.577 to 10.597 GHz and this came into force on 26th June 2013.

The existing band 10.675 to 10.699 GHz can continue to be used by existing systems, but it will be closed for new systems on 30 December 2014 giving manufacturers 18 months to switch to the new band.

Mobile terminal handsets using WiMAX or LTE in the 800MHz, 2011MHz and 2.6GHz bands will be license exempt (when connected to a licensed mobile network i.e. BT, EE, 3UK, O2 or Vodafone).

Various satellite terminals will also be license exempt in the 1518 to 1525 MHz, 1525 MHz to 1559 MHz, 1626.5 MHz to 1660.5 MHz and 1670 to 1675 MHz bands.

Vizz(ualise) your LinkedIn contacts

There's a really nice little iOS app (currently iPhone only) called Vizz that visualises your LinkedIn network.

You can see what industries your connections are in, where they're located, what companies they work for and who's changed roles recently.

Quite a useful little app, all for the princely sum of £0.69 (69p).

Admittedly I do know the author @hakimmobile, but that doesn't change the usefulness of the app.

Video Highlights: Augmented World Expo

Augmented World Expo featured some impressive technologies, and one of my favorite booths was Daqri's 1893 World's Fair Experience.
I was very impressed with Steve Mann's keynote, history as the father of wearable computing, and his work with Meta as Chief Scientist. I tried out Meta's glasses and was impressed with how I could reach out and grab 'virtual' objects and bring them closer to me.
 
The Meta team was inspired by the interfaces in films like Iron Man, Avatar and Minority Report and wanted to make them a reality. Their Kickstarter meta 1 Developer Kit has the power to deliver a natural interface between the virtual world and reality.

Tech Specs include:
Hardware:
Field of view: 23 degrees for each eye, in the centre of the field of vision. Appears five metres away from the viewer before stereoscopic effects are applied which allows perceived distance to vary.
Projection: two individual screens, one for each eye, appear in front of the user, so as to render in stereo.
Resolution: 960x540 for each eye
Weight: 0.3 kilograms
Supported Platforms: Currently Windows 32bit/64bit. Support for other platforms is in development.
Inputs: HDMI/USB
Software:
Develop Using: Write code in Unity3D on a Windows PC. Other platforms will follow.
SDK provides: Gestures and Finger tracking, general depth data that works with any objects in range of the depth camera, RGB data and surface tracking (access planes and meshes of surfaces in the real world, so you can anchor virtual objects to them, or augment them in other ways.)

Here are the short videos I took at Augmented World Expo.

Everything you wanted to know about (upgrading to) BB10, but were afraid to ask

A few weeks ago I received a Blackberry Q10 that I had won in an EE competition. It was sent directly to me from Blackberry in the UK. Unfortunately it was locked to EE and I am an O2 customer, but with help from Blackberry an unlock code arrived in Email the same day.

The Q10 was sent out with various bits configured for EE, which I queried and was told "once the new SIM works, the device gets the settings from the network", so again all well and good.

Next install Blackberry Link which is the new desktop software from Blackberry, again all well and good, except though it can now sync photos/music/documents/etc with the desktop (a Mac user) it no longer (compared to Blackberry Desktop Software for Mac) syncs Calendars and Contacts. The new BB10 devices (Z10 and Q10) are completely device centric and all email/calendar and contacts synchronisation is done by the mobile device itself.

I plugged in the old Blackberry Bold 9900 (which Blackberry Link recognised as a OS7 device) and it asked if it would like to transfer the databases, to which I confirmed.

All seemed well, except you have to set-up all the old email accounts/etc on the new device before it actually works and it seems not all of them were working (GMail specifically, luckily the set-up of a BB10 device can be done using WiFi so it doesn't need a SIM in the device to actually set it up).

The email accounts were all working, try the transfer again and all went well.
Then (after reducing the SIM from a normal size to a uSIM using a SIM cutting tool) put the old (u)SIM into the Q10 and bang, everything works (well at that point the phone needed unlocking, but that was very simple and just required entering the unlock code - though not in the way Blackberry had stated, go into settings, then security, SIM and then you are asked to unlock).

On the Mac iCloud is the default system for contacts and calendar, so on the Q10 just add a new Email account (i.e. iCloud account). That's where problems started. There is a known problem using iCloud for newer versions of BB10. The Email account is set-up fine as is contact sync, however it fails to set-up the calendar sync (with a credential issue).

It's also possibly to directly add a Caldav account in the advanced Email set-up, again the forums were awash with suggestions but it should be possible to just add caldav.icloud.com as the calendaring service, but again this failed with a credential issue and would not complete.

Search the forums and lo and behold there's a Blackberry knowledge base entry which states "there's a known issue with Apple's caldav services" (Apple uses CALdav for calendar synchronisation, it also used to work on older versions of BB10, the phone upgraded itself to v10.1.0.273 via the WiFi, some earlier version of 10.0 used to work). The forums also stated that after speaking to Blackberry users had been told to report the fault to their carrier who could then escalate to Blackberry, the more users/carriers reporting the fault would increase the escalation.

So decide to phone O2 and report the fault and managed to get through to the Blackberry specialist team, explaining that I had upgraded from a Blackberry Bold 9900 and was now using a Q10 and wasn't able to sync calendars. They explained they would look at the problem and get back to me, which they did. Unfortunately they wouldn't escalate the problem as it was a known issue by Blackberry and thus couldn't escalate. I tried to explain that even Blackberry themselves were telling users to go through their carriers to report the fault, but they were adamant that they wouldn't be able to report the fault as it was already "on the system".

So no calendar synchronisation, but the phone seemed to be working well apart from that, email coming through, twitter/Facebook/LinkedIn all seemed to be doing the right thing.

There are some immediate quirks though: -

  • On the old Blackberry you can delete an Email on the device or delete it on the device and the Email server. this is no longer possible and deleting an email deletes it completely. This isn't disastrous it just means you get a lot of emails on the device, the Email icon turns grey if read, but it's still there. After 90 days it is possible to to set a shorter time) older emails will disappear.
  • The old twitter client used to support multiple accounts, the new one in BB10 only supports a single twitter account, this is a real pain. Direct Messages (DMs) and mentions (@) appear in the hub, which is fine, but the actual twitter client only supports a single twitter account itself. Would be happy if the Hub just supported DMs and mentions from the active twitter account, but the actual twitter client should support multiple accounts and the user can select which twitter account to be active.

So only a single twitter account, no way to delete emails off the device without deleting them on the server, and no calendar synchronisation, but all is work.

Now the fun really starts

On the 30th of May I get an email/text from O2 saying my bill is £470 more than it is usually.

I contacted customer services and ask about the problem and am told that it's data charges, so I tell them my settings (Blackberry Unlimited tariff and APN set to mobile.o2.co.uk) and it's confirmed those are the correct settings, but the customer services agent has started a "Network Investigation" and I wont get anymore data charges.

I am not convinced, but hope that all will be good.

On the Saturday I get another email/text now saying that my bill is £580 over my normal bill.

Unfortunately it wasn't until Sunday that I managed to contact customer services again. This time I'm told that I should move to a normal data tariff and that the old Blackberry Unlimited tariff is very old and not available to new customers and I should move immediately (the tariff has a 750MB data limit, which I've exceeded in the first week). I refrain saying I will wait for the network investigation.

I then decide to do some of my own investigations and find that the new BB10 devices don't work how the old pre-BB10 devices work (the old BES and BIS connections went through a "hardwired" blackberry.net "private" APN that was embedded in the Blackberry software itself). The new devices (at least for a BIS - which is the Blackberry Internet Service) now do use the actual Internet data connection and don't have the cludgery that was the old style BIS connection. The devices have become completely device centric ...

However on some forum it's stated that setting the APN to wap.o2.co.uk works and as it's with the Blackberry Unlimited service, it's free. So I plug that into the Blackberry and lo and behold no more data charges.

I also phoned O2 support to check and they agree that setting will work.

I still have a massive data bill and there is an on-going network investigation.

Twitter to the rescue

I have had a few conversations with @O2 on twitter, who are very responsive to tweets and good for sorting technical and other issues and get into a discussion with the "web team" who DM me and ask for details of the problem, which I duly sent them. It seems they have a massive influence and today (Tuesday 4th of June) I get a call from O2.

Unfortunately I do have to move to a standard new tariff (that only comes with 750MB of data), but they are going to wipe the data charges (eventually £600+ +VAT).

As soon as the tariff is changed (should come into play tomorrow), it looks like I'll have to ask for a PAC code and move to a new network, one that does unlimited data.

I've been a loyal customer with O2 on this number since 2005 (and on another number - moved to GiffGaff a year ago, since 1984). It will be a shame to move, but unlimited Internet is unlimited Internet.

So long and thanks for all the fish as they say.

ARM Mali now has DRM on-chip

ARM the company that designs microprocessors and micro-controllers that are used in high-end smartphones down to dishwashers has announced a new range of graphics co-coprocessor with digital rights management (DRM) built-in.

ARM has been forging relationships with bodies to support its TrustedZone security implementations in its ARM cores, now it is extending this with DRM backed into its video processing hardware (Mali) and it has just announced the Mali-V500 which supports 1080p/60 encoding and can decode up to 120 frames per second with a resolution of 4K. This should make the chips appealing to video companies like Netflix who want modern hardware, but also want to appease Hollywood with native DRM support.

ARM have also released new CPU cores, the Cortex-A12 (mid-range smartphone, faster than current Cortex-A9 technology). ARM also boast the performance of the Cortex-A15 supersedes Intel's low power core technology, even though it's based on their new 3D transistor at 22nm.

Newer ARM chips will migrate to 20nm technologies and even 16/14nm designs and they say that will keep them ahead of Intel for the foreseeable future.
