Outstanding bandwidth tests with Speedtest.net http://techpaedia.com/2006/08/20/outstanding-bandwidth-tests-with-speedtestnet/ http://techpaedia.com/2006/08/20/outstanding-bandwidth-tests-with-speedtestnet/#comments Sun, 20 Aug 2006 12:35:58 +0000 Ash http://techpaedia.com/2006/08/20/outstanding-bandwidth-tests-with-speedtestnet/ More after the jump.]]> While there are many companies out there offering to test your internet’s connection speed, some will even charge you a subscription fee for a simple Download and Upload rate.

This is where Speedtest.net really stands out. It’s FREE and it has an outstanding graphical user interface that overlays your location and that of its servers on a map.



After the speed test, Speedtest.net displays the results and offers you a cool banner to display them in any webpage!

Another interesting feature of Speedtest.net is that it saves all test results originating from your IP address and displays them every time you visit their homepage!

In fact, on my first visit to Speedtest.net I was greeted with a set of results already!

I actually connect to the Internet from behind a NAT (Network Address Translator) on a corporate network. So, there are many others who share my external IP address!

It seems like at least another person on my network has discovered Speedtest.net before I did! And whoever it was somehow has a much better connection than I do despite being on the same network and sharing the same external IP:

iPod Full Body Invisible Shield http://techpaedia.com/2006/08/10/ipod-full-body-invisible-shield/ http://techpaedia.com/2006/08/10/ipod-full-body-invisible-shield/#comments Thu, 10 Aug 2006 22:00:13 +0000 Ash http://techpaedia.com/2006/08/10/ipod-full-body-invisible-shield/ removing the invisible shield screen protector on my iPod, I applied the full body shield which covers just under 100% of the iPod's surface.

After removing the invisible shield screen protector on my iPod, I applied the full body shield which covers just under 100% of the iPod’s surface. Once again, I’ve been very impressed with the results!


I am most pleased with the ability of the back cover shield to prevent fingerprint stains. If you’ve always hated the way the back metal casing of your iPod attracts fingerprints, the invisible shield will definitely put an end to this while at the same time protecting it from scratches in a way that no iPod case will.

The shield also covers the click wheel. And contrary to what I initially thought, the click wheel is just as touch sensitive with the shield on as it was without.

However, it may be worth noting that the full body shield covers all surfaces except:

  1. The small areas in each of the four corners on the back metal casing
  2. The area around the hold switch and the ear phone socket
  3. The area around the dock connector port

You can see this for yourself in the close up pictures below.





Also worth noting is the fact the the top surface (the face with the click wheel) is slightly more reflective with the shield on than without. You can probably just about make this out in the very first picture.

And below are a few video clips of me applying the shield. It was a rather time consuming process and it wasn’t all that easy to position the shield in exactly the right spot, specially so with the main top and bottom shield. But with a bit of patience and perseverance, one will eventually get it right.



If you are planning to apply a shield to your iPod, I would highly recommend that you watch the demo video from shieldzone.com first. Also, make sure you have a lint free cloth handy. Kitchen towels or kleenex tissues just won’t do it: They will only get stuck permanently to your shield or leave some debris on it. The cloth featured in the above video was an optical cleaning cloth from Jessops which I also happen to use for my glasses and my camera lens.

If you find that there are some stubborn bubbles hiding under the shield after you’ve applied it, I would suggest peeling it back off immediately and reapplying (assuming you have enough of the spray solution left).

But if you are left with small bubbles, no need to worry because those will sort themselves out after the drying process, usually after 24 hours. But it can sometimes take up to 72 hours for the shield to fully set itself.

Modular PC: Dell XCS Concept PC http://techpaedia.com/2006/07/31/modular-pc-dell-xcs-concept-pc/ http://techpaedia.com/2006/07/31/modular-pc-dell-xcs-concept-pc/#comments Mon, 31 Jul 2006 15:34:19 +0000 Ash http://techpaedia.com/2006/07/31/modular-pc-dell-xcs-concept-pc/

In an age where the Hi-Fi is becoming obsolete, designer Matthew Ritter has come up with this Hi-Fi looking concept PC! The idea is to design all internal components as cartridges which the user can very easily take in or out.

“Each component is a modular and shaped so that it cannot be inserted into the wrong place. A number system was also developed to replace confusing specifications that are present on today’s software.”


It would be great, if this design made it to the market. No more digging into the messy internals of current PCs to simply add a second hard drive or more memory!

We’ll have to wait and see whether Dell will bring out the XCS anytime soon. Or maybe Apple will beat them to it by introducing this modular concept in the yet to be announced Intel Power Mac replacement.

Removing invisible shield from iPod: Easy? http://techpaedia.com/2006/07/25/removing-invisible-shield-from-ipod-easy/ http://techpaedia.com/2006/07/25/removing-invisible-shield-from-ipod-easy/#comments Mon, 24 Jul 2006 23:28:07 +0000 Ash http://techpaedia.com/2006/07/25/removing-invisible-shield-from-ipod-easy/ A few weeks back, I got an invisible shield for my iPod's screen. I was so satisfied with it that I decided to go for a full body shield for my iPod. Now that my all new full body shield is here, just how easy will it be to remove the old screen shield so that I can put on the new one? According to the FAQ on ShieldZone's website,
Q: How do I remove the invisibleSHIELD if I need to? A: Removing the invisibleSHIELD from your electronic device is easier than it may seem. It is much like peeling off a sticker. You will want to start at one corner and slowly peel back small pieces at a time until the invisibleSHIELD has completely been removed from off of your device.
Is a material as tough as the invisible shield (which was originally designed to protect the edges of military helicopter blades) as easy to remove as ShieldZone claims? Let's find out! Video of the removal after the jump!]]>

Conclusion: The invisible shield is strong enough that it won’t come off accidentally but if you need to take it off for any reason, that won’t be a problem! In fact ShieldZone recommends that you remove your shields if you have to send off your device for repairs and they will send you a brand new shield free of charge to replace it!

USB “Air Conditioned” Shirt http://techpaedia.com/2006/07/20/usb-air-conditioned-shirt/ http://techpaedia.com/2006/07/20/usb-air-conditioned-shirt/#comments Thu, 20 Jul 2006 21:46:13 +0000 Ash http://techpaedia.com/2006/07/20/usb-air-conditioned-shirt/ Ex Sony technician, Kouzi Ichigaya has come up with a simple idea to keep cool this summer: The USB Air Conditioned Shirt. It’s powered either by USB or AA batteries or through your car’s cigarette lighter.

Somewhat to my disappointment however, it’s not exactly air-conditioned. The shirt simply features two fans on each side of the waist which blow air inside the shirt. This leads to evaporative cooling by vapourising sweat without the use of any heat pumps as is the case in air conditioners. It’s nevertheless a cool idea, but to be fair, I think it ought to be called the air-cooled shirt.

Following some research funded by NIST (National Institute of Standards and Technology) at Seagate, it was found that nanotubes that leak a lubricant vapour could lead to 10x bigger capacity hard drives!

Nano Tube

The technology is based on the concept that more information can be stored on a magnetic hard drive by heating it. However, until the nanotubes came into play, it was impossible to operate hard drives at such temperatures because they cause all the lubricant to evaporate. This in turn leads to the recording head crashing onto the the surface of the disk and damaging it.

The nanotubes allow the lubricant to leak out slowly as the disk spins and covers its surface. Also, because the hard drive is sealed, the lubricant vapour cannot escape and it is expected that the nanotubes will hold enough lubricant to last the lifetime of the drive.

After combining this technology with heat assisted recording, Seagate expects to achieve storage densities of several terabits per square inch, 10 times more than is possible today.
