MATRIZ DE CUMPLIMIENTO DE LA NORMATIVA AMBIENTAL

screwdrivers and an eBay seller supplied some orange LEDs for just a few pence each. The converted nightlight, which was not worth making from scratch, works wonderfully on my landing at night, enabling me to bask in its amber glow.

The web turned up trumps – or nearly anyway – when trying to repair my Pure Evoke Flow IP radio receiver, a birthday gift that I first reviewed nearly a decade ago. I tune into a US radio station which, as I write these words, is finally closing down its FM channel after many years and going online instead. (The friendly DJ in South Carolina graciously namechecked me before going off air for the final time.) In fact, I struggled to tune in at all as the Evoke’s vivid yellow OLED display was fading fast, a victim of old age – I had to go underneath my desk to check it! Many other Evoke users have reported the same problem. Hunting online, a replacement looked a simple matter and other fans highlighted the display manufacturer, Taiwan’s Bolymin, along with a part number that turned out to be only available from Britain’s RS Components. It is presently halfway through its six-month lead time, so we will see who blinks first or gives up.

Thanks to information like this and more found on the web, there is a fighting chance of giving the radio a new lease of life, even if my favourite radio station is sadly no more. The DAB radio’s British designers, Pure, was itself sold off by Imagination Technologies to Austria’s AVenture GmbH last year.

Still with DIY repairs in mind, an enormous range of watch repair tools are sold on eBay and Amazon. These tools enable you – if your eyesight allows – to swap quartz watch batteries easily. A jeweller quoted £50 to swap a quartz movement on an inexpensive watch, so it was time to check out what’s available online. Tools that push out strap pins, gadgets that unscrew or pry off a watch case back, and lever-presses that close them back together again – were all available on the web and could soon pay for themselves, much to the chagrin of my local jeweller. A quartz watch Miyota movement (£6.00) arrived from Greece, and specialist tools for removing and affixing watch hands came from China in a convoy of little packets. The web taught me that standard watch movements – called calibres – are found in many popular watch brands and their size

is measured in French lignes. For mass-produced watches, the maker merely designs the case and strap, which can be made in Hong Kong, and drops in a standard movement costing a few pounds.

Armed with new insights like these, there’s no denying the empowering effect that the Internet has had, with inside information, products, parts and tutorials now just a click away. Sadly, however, my DIY watch repair was a failure, as a mangled second-hand will testify! It was fun finding out though.

Dashcams and Facebook

Increasing numbers of traders, including Chinese vendors sell merchandise using ‘FBA’ (Fulfilled By Amazon) where the parcel-peddling monolith takes care of all logistics and customer order processing on the seller’s behalf. This can create a worrying disconnect between the customer and the supplier, with buyers sometimes reliant on Amazon’s review or Q&A system to get technical support – if they’re lucky. FBA vendors tend to chop and change, making it hard to know who you are dealing with or whether they will disappear overnight. If you want to know how FBA works, details are here: http://tinyurl.com/zjd9mrh

In the July 2016 issue I mentioned a car dashcam branded as K&F (Kent Faith, a Chinese seller of photo accessories) that I sourced from an Amazon FBA seller. The generally excellent 1296P HD camera was bundled with some Windows software that constantly locked up when viewing journeys on Google Maps. As I mentioned in the article, the problem was caused by its out-dated reliance on Google Maps that no longer integrated with the software properly. The best solution was found in RegistratorViewer, an excellent program written by the late Vadim Kozlov that handled dashcam .mov files with ease. It is still available free from www.registratorviewer.com/index_en.html. Just run the .exe, point it to the camera’s memory card and pick Bing Maps instead.

I noted some memory card issues with this camera just as the FBA seller morphed into the oddly-named ‘Beschoi’, so I wondered if I had been left stranded with a device that didn’t record properly. For once, though, Amazon’s customer feedback pages yielded a very helpful email address and I was quickly sent a flash upgrade by the mysterious Beschoi. The upgrade process could be charitably described as ‘somewhat non-English’, but it worked and the camera’s boot screen changed to Beschoi too. Happily the device has worked flawlessly ever since.

RegistratorViewer lets you trim the footage to export as a separate movie file. However, the resulting gigabyte- size files often make it impossible to share them or upload onto Facebook (which will simply throw them out), so the quest has been for a simple video converter that would compress larger .mov files into MP4s suitable for Facebook or YouTube. Many dubious graphics programs are sold online, but I finally found one that seemed to fit the bill (it’s

free!). Macroplant Adapter takes in unwieldy .mov files and compresses them into MP4s and allows many minutes’ worth of video to be uploaded onto Facebook without losing too much detail. Over on Facebook, videos can then be viewed in HD mode (click the player’s cogwheel icon and choose HD) and the quality is perfectly acceptable, especially on a smaller tablet or smartphone. The clarity was so good that Facebook kicked out another dashcam video, stating that the car radio music was infringing copyright. Facebook named the tune, as well!

After experimenting with Adapter I found the software’s ‘Video Custom MP4’ setting worked well. Other formats include .avi and animated gifs. You can also add layers to a video, eg, for text and audio, and .srt movie caption files can be imported too. This has yet to be actually tested, because unfortunately the program repeatedly crashed on the subtitle dialogs, but this bug may well be fixed in the future. Details on creating .srt subtitle caption files for your movies can be found at: http://tinyurl.com/lezax5b. Both Mac and Windows versions of Adapter are available.

Smarter spearphishing

EPE readers know all too well how vigilant you must be

when surfing the Internet, handling files or dealing with suspicious emails. Some criminal attempts at ‘phishing’ are almost embarrassing and can be dismissed instantly, but a hard core of determined criminals is becoming extremely sophisticated in its efforts to trick victims into visiting a website or opening a document that will attack their PC. Only once have I come close to falling victim to such tactics, when a close friend’s email was hacked and the fraudsters impersonated her style of writing very well, but then the penny dropped that something wasn’t quite right. I lost no money, but I admit it was a close thing. When confronted by such social engineering, human intuition can be more powerful than you think, so ask yourself, ‘does it pass the sniff test?’ If something doesn’t quite ‘smell’ right somehow, tread very carefully indeed.

This week, I received a spearphishing email that shows just how clever these crooks are becoming. Spearphishing is a highly targeted attack aimed at an individual, perhaps using personal data stolen from a website, club, association or other source to add to its supposed authenticity. For reader reference, the email is reproduced below and it contained my name in the subject and supposedly my home address in the body. It’s likely that the sender’s name and email address had been spoofed. Probably, the crooks knew nothing else about me, but it was a very cunning attempt to pique my interest, hoping I would open a Word file and run a malicious macro.

Subject: Alan Good day to you, Alan!

I am bothering you for a very significant matter. Allhough you don't know me, but I have considerable ammount of data concerning you. The fact is that, most probably mistakenly, the information of your account has been emailed to me.

For instance, your address is: XXXXXXXXXX XXXXXXX

XXXXXXXXXXXX XXXXXXXX XXXXX XXXX XXX

I am a law-abiding citizen, so I decided to alert may have been hacked. I pinned the file - Winstanley.dot that was sent to me, that you could explore what data has become available for deceivers. Document password is - 9583

Sincerely, xxxxx xxxxxxx
