How to solve a wifi issue between Nokia 5530 and a Thomson TG787 router

So, my wife bought a Nokia 5530 Xpress Music phone and was very eager to try it, especially the Wifi since she could now connect to Facebook and e-mail at home without having to use my Mac or iPod Touch :-)

However, the experience was not that thrilling since the phone was unable to connect to our our home router (a Thomson TG787 provided by our ADSL provider).

After trying several different configurations (with WEP, WPA, WPA2, without encryption, etc...) and with other gadgets (iPod Touch and Nokia N80 could connect successfully to every configuration) I was very frustrated that I couldn't find a working solution.

At that point I went out and while at a shopping mall I was able to try some public wireless networks and it worked immediately. This increased my frustration to an even more absurd level. Back home, the problem remained.

It was only when, while using some Google-fu, I was able to find this forum post (in Portuguese) that I could finally solve the problem. Even though this post refers to the Nokia 5800 Xpress Music, the solution appears to be suitable for the 5530 model as well.

So, basically all you need to do is some Terminal action:

• Open Terminal (on a Mac) or a command window (in Windows)
• Run the following command: telnet 192.168.1.254
• This will give you access to the router, but you have to insert the username (Administrator) and password (the password you defined)
• Once an administration console appears, write: wireless qos config mode=disabled
• Then hit Enter
• After that (it takes a few seconds to compute) write: saveall
• Then hit Enter
• Just exit and you're done

The Nokia 5530 phone was able to connect to the home wireless network... success, finally!

Final note: I don't know exactly if this affects only this type of phones, but my Nokia N80 worked fine without the need to do this hack. Also, I don't know exactly what this hack does to your router so beware. So far, I haven't noticed anything different on all other devices, so I won't reverse it. By the way, if you need to restart your router, this configuration is lost, so you'll need to do it again.

The invisible flash

Using the flash while taking some photos may be, in some situations, the only choice you have in order to produce decent lighting in a picture. However, most flash pictures are ruined because of the excessive light in the foreground and not enough light on the background.

In the ideal world of photography, a camera would be able to capture just enough light to make the picture perfect but not suffer from the disadvantages of using flash. Basically, what we need is an "invisible flash". But how can one produce such a paradox: a blast of light but that is not visible?



The answer is given by a student of the New York University, Dilip Krishnan and his advisor Rob Fergus. They have developed a dark or invisible flash which uses infrared and UV light to take photos in dark places without the nasty glare of a standard flash.

Basically, what they did was modify a light bulb to emit light over a wider range of frequencies (not visible at the human eye). They also changed their camera to adapt to these new conditions by using a set of filters to prevent the silicon image sensor from detecting infrared and ultraviolet rays.

This is not exactly new as this is more or less like night vision works. The difference is that, instead of having those photos where we all look like vampires, they managed to find a way to produce the correct colour balance by taking a quick colour image right after the dark flash image.

Even though the image produced in this second image is of low quality (grainy and unclear), the colours are correct. This allows them to produce a correct final image by using special software that combines the information from the photos (you can see the process on the 3 images above).

The technology is not yet perfect but it definitely looks pretty promising. To know more about it, you can check the website here.

Anti-paparazzi gadgets

Adam Harvey, a student of of Interactive Telecommunication at New York University has created a new gadget that will probably be the next sensation of all those paparazzi-harassed celebrities: a purse with a flash sensor and flash.

So what does it do? It's simple. The purse contains a sensor that is triggered by any flash going off, and it instantaneously fires its own flash, completely ruining paparazzi shots.

A few gadgets that I would love to see on my kitchen

Sauce Dispensing Chopsticks


People who love sushi like I do, know it's not easy to get all those food sculptures from a plate to the sauce dish and then to the mouth. Using these special chopsticks you can avoid some embarrassing accidents with the sauce and simply enjoy your sashimi.

D-Cell Battery Salt & Pepper Shakers


The D-Cell Battery Salt & Pepper Shakers are simply great. Not only you'll surprise your friends with such a neat gadget, you'll also be able to see how much “power” (or pepper) you have left through the power indicator panels so you know when to “recharge.”

Spinning Spaghetti Fork


It's not that easy to do all that spinning in a full-of-sauce spaghetti plate, so why not use this electrical fork and make things a lot simpler?

Sharky Tea Infuser


How cool is that? To have a shark swimming around in your cup of hot water, while the tea is getting ready. Pure awesomeness!

Portable Toasters


Here's a gadget that I totally dream off. I hate my toaster because I can never tell when the bread is done. Sometimes it burns the bread, other times it simply is not enough. How to know for sure? Well, do it manually with this portable toaster.

Rechargeable batteries with solar cells

Now here's a great idea: integrate a solar cell directly into a rechargeable battery so that it can recharge just by facing the sun.


The SunCat batteries were born when its creator wondered as to why "hasn't anyone made a battery with integrated solar cells" and answered: "The batteries should just bask in the sun like a cat and left for a while, in a sunny window, they would slowly recharge."

I think it's a great idea and the good part is that you can do it yourself... that is, if you can get around the necessary parts and have the skill to build them :-)

Just check the SunCat blog post for details, here.

Why hasn't anyone thought of this before? - part II

In the category of "Why hasn't anyone thought of this before?", this week I give you: the transparent duct tape.

Why should you give your stuff that broken-like aspect with a coloured duct tape, when you can use this transparent duct tape that seamlessly re-attaches broken stuff? It's a mystery to me how these "oh, so simple" innovations keep showing up today when someone could already have thought of them years ago.

Not much explanation is needed. Tool manufacturer Irwin has come up with a great alternative tape measure, Strait-Line, which has its own integrated marking tip, so you can leave a cut line with the other hand free. Plus, you no longer have to look like a carpenter with that pencil tucked behind your ear. Well, unless you like it...

The alarm clock suitable for couples

This concept alarm clock by Johan Brengesjo (which is interesting enough to add to my collection of different alarm clocks) is an excellent idea for couples that have to get up at different hours and don't want to bother each other with different buzzing alarm clocks.

How? Well, a wireless rubber ring with an integrated vibration device is worn on the finger (the alarm clock has two-user settings and there's one ring for each person). When the alarm "rings" only the corresponding ring vibrates and the person can wake up by sensing the vibration. The light function and the snooze function are engaged by shaking your hand. Move your hand and the snooze gets activated.

My new gadget: iPod Touch 16 GB

Finally, I found the time to talk a little bit about my new gadget: an iPod Touch 16 GB.


Why an iPod Touch?

I've always felt the need to carry a pocket device to have access to e-mail, calendar, notes and news and the PDAs that I used in the last few years have all been Windows Mobile-based. However, ever since I switched to a Mac, I've been using these gadgets a lot less. Why? Because I got used so much to the simplicity of Mac OS X, that now Windows Mobile usability seems too weak. So, since I already carry around an iPod to listen to my tunes, the obvious choice was to switch to an Apple-based device that would combine everything.

(in case you're wondering how I made the "Lock Screen" look like that,
check here)

You might ask: "why not an iPhone, since you're looking to merge all functionalities into one gadget?". Well, because buying an iPhone would end up costing me a lot more than the iPod Touch and since I don't use a mobile phone that much, it didn't make much sense to me (the only thing I regret of not buying the iPhone is the GPS, which is not included in the iPod Touch.).

The first experience

After exactly 46 hours of hitting the "Buy" button on the Portuguese Apple Store's website, I received my iPod Touch. Any Apple product's case is a pure mix of creativity and simplicity and, as expected, the iPod Touch's is no exception: small, clean and appealing.

The first experience was absolutely perfect...really, it couldn't have been better. I was amazed with the simplicity of the syncing process. After connecting the iPod to my Mac and providing some information for the registration process, the synchronization process automatically took care of everything: music, movies, tv shows, photos, podcasts, calendar, contacts, bookmarks and e-mail settings. I only changed a few options (to avoid syncing all tunes, photos and movies - because 16 GB is just not enough) but basically after the syncing process, my iPod Touch was ready to use. The e-mail settings synchronization was the thing that most amazed me. I didn't have to configure anything on the device and the mail accounts were ready to be accessed.

(in case you're wondering how I took a screenshot of
the iPod screen, just click the home button and the
sleep button at the same time. The screen will flash
and the screenshot will be stored in your photo library)

The App Store

The use of the App Store on the iPod Touch is clean and simple. Just choose the app you want, click install and it's ready to be used. Don't worry about purchasing apps on the device that may get lost. On the next sync the apps are backed up on your computer. Even if something happens during the download process or with your device, the apps are available for re-download from the App Store on your computer. Soon, I'll make a post dedicated to the best apps I've found on the App Store so far.

Usability

Regarding the iPod Touch usability, sure it's amazing but it's still far from perfect. These are some of the things I don't like:

• No Alt+TAB-like feature. There's no notion of what happens to applications when you press the home button and there's no way of effectively switching between two applications without going to the home screen. I know that you can hold the home button for 8 seconds to close an application but that feels more like a "Force Quit" than a real nice clean Quit.
• No wide keyboard on Mail. It's quite ridiculous that Apple decided not to put a landscape mode-based keyboard to facilitate writing mails (I know there are applications that take care of this, but again it feels like a cheap fix). I already got used to fit my chubby fingers on the normal keyboard, but the usability of a wide keyboard is undoubtedly better.
  

And of course, another list is required. These are some of the things that I love about it:

• Accelerometer. This amazing feature is what turns this simple gadget into something so much amazing. Whether it's on iTunes or while playing games, this feature is pure fun and will enrich any application that makes use of it.
  
• Touch interface. Everything is quite intuitive, easy to use and it's just a touch/slide/pinch away.
  
• Scrolling effect embedded in every functionality. It feels so realistic that now I'm starting to do similar movements while reading books or other paper documents :-)
• Wireless Configuration. Simple and right to the chase, no excessive prompting and with the right amount of useful information.
  
• Concentrated settings. Most settings are concentrated on a single place, so as to avoid complicated menus and options/settings within each application.
• One button to rule them all. There are no complicated rules to learn. When in trouble, just click the main button on the iPod. It will always take you to the home screen. Need to quickly access the now playing section of the iPod to pause/next tune or change the volume? Just click twice.
  

Protection

I bought a hard plastic case to protect the iPod, since now this will be my main gadget and will go anywhere I go (well, maybe not sauna or shower). It looks great and it's light enough to go by unnoticed:


My new media center

Amazingly the video resolution for the iPod Touch is acceptable enough to connect it to the TV and view some of the videos and TV shows on it. You can easily convert any videos that you may have on your computer to optimal iPod Touch/iPhone settings using QuickTime. And the best thing about it, if you have subtitles to load with the video file, the video output of the export process will include the embedded subtitles.

So, using Apple's Universal Dock connected through S-Video to my flat screen TV, I can easily see any videos/photos on my TV and even control playback using the Apple Remote.

In conclusion

The iPod Touch is the perfect hand-held to complement my Macbook Pro. Syncing data between the the two is amazingly easy and fast, so it's easy to have access to all my tunes, videos, mails and news. The App Store makes it even better, offering a wide range of excellent applications that you can install on the device, thus turning it into a portable gaming console, an encyclopedia or even a ruler :-)

After 2 years of development, this is what they ended up with

It's funny, the yet-to-be-released Meizu M8 kind of reminds me of something else, but I can't quite figure out what. Perhaps you can help me remember?
