WowWee WiFi Home Security Robot Price Drop

 

Being connected in today’s world is easier than ever.  And since we are all connected, we may spend more time with our connections and away from, as George Carlin so aptly put it, away from our stuff.  But the same connections can be used to keep track of our favorite stuff.

Enter the WowWee spybot, Rovio.  Unlike a simple webcam that lets you check in on your, well, stuff, it can let you go walking about in a virtual way, keeping a watchful eye.  But not just an eye – you also have an ear, thanks to the built in microphone.  You can even remotely participate thanks to its two way communications capability.  All you need is a remote internet connection.

The little robot works via WiFi, and it incorporates built in GPS navigation.  You can set a point and, with a remote click of a mouse, the unit will go to a designated point (you know, such as the other side of a corner to see if everyone is actually talking about you, as you suspect…  and if you think this, they probably are, but only a frank discussion about your paranoia).

Nighttime reconnaissance missions are not a problem either, since the Rovio sports its own onboard LED light source to show the way.  So the little unit is handy whether you are traveling or just want to check out what the noise is down the hall from the comfort of your bedroom.

 

Personally I think it would be cool to get two and play a little robotic hide and seek with a friend across the room or across the country. Perhaps strap on some IR cannons and even play a little VR war game,  Yeah, I’m feeling it. A quick price check showed the Rovio to be available from Amazon as of this writing for $265, down from the earlier $349 introductory price.  Not cheap, but getting into the affordable range.  And as with any introductory unit aimed for a mass consumption price you should probably expect there to be hiccups. But as something with a lot of fun potential this looks to be pretty cool.

How to make an inexpensive but VERY bright LED flashlight

 

We all have seen, and maybe even own at least one, LED flashlight.  The lights can be quite handy and durable, without the fear that you are going to suddenly have a bulb burn out on.  The lights tend to be much more miserly with the power as well, letting the user carry a smaller package for lighting that also has an impressive battery life in the field. As you can see by the list below, LEDs offer many advantages over standard incandescent lighting:

However, one thing that LED lights are not typically known for are their extreme brightness.  Typical LED lights run in the 40 lumen range, enough to be of great help in the dark but maybe not in the “comfort” range. But by combining LEDs you can greatly increase their total output, and options are readily available at sellers like Amazon.

Youtube user Jayandersons has his own solution for adding more umph to a LED light.  His interesting project takes a $23 SSC-P7 LED unit and hooks it up to a $10 light, making it 20 times brighter and upping the total output to an impressive 900 lumen.  This is claimed to be enough to shoot a beam of light over 3 miles, not to mention light up a room quite cozily.

Microsoft Explorer mouse boldly goes where other optical mice cannot

Using an optical mouse, as compared to the old ball driven units, is a joy to behold, but only if you have suffered from using the older mice.  Yes, there is no fuzz, thread, bits of paper, or even indescribable bits of black stuff to contend with when popping out the ball to clean it.  However, there are some instances where the old ball type is actually better.  Now, there are very few places where this is true, such as a shiny table top, and if the new Microsoft Explorer mouse lives up to its name there may be a lot fewer exceptions to the optical mouse superiority title.

Instead of a ball physically rolling on a surface, an optical mouse uses a light source, typically a red LED or laser, to light up a surface.  The mouse then takes a picture, and analyzes it for any number of tiny shadow bumps cast by very slight surface imperfections.  This process is done quite quickly, and when you move the mouse, a process compares the shadows to determine what direction you are moving the unit.

While the process works great on most surfaces, it does have its weaknesses.  If it is an extremely smooth surface with little imperfections for shadow creation (shiny), or if the surface is varied with gaps that let the light pass through without any reflection (carpet), then there are simply no shadows to compare, and the mouse is convinced that it has not been moved.

Did you know?

The first known publication of the term "mouse" as a pointing device is in Bill English's 1965 publication "Computer-Aided Display Control".

Microsoft's Explorer mouse addresses this by moving the camera sensor forward to capture not only the light the mouse emits but also light reflected by any part of the surface. The new position also allows the mouse optical sensor to take a wider picture of the subject area, increasing the chances of a good "read".  

Unlike other optical mice that typically incorporate a red LED, the Microsoft Explorer mouse uses a distinct blue LED source which runs through a diffuser, allowing it to shine wider and more even than the other light sources.  This also increases the odds that the mouse can grab those all important diminutive surface imperfection shadows.

Of course, the mouse tech sounds impressive on paper, but how it works in the real world is the true determination of its practical worth. PopSci did a test on the Microsoft Explorer mouse, and the results were quite good.  From their website:

The Explorer did better than promised. It worked not only on plush rugs and angry pets, but also on clear glass, one of the two surfaces Microsoft says it can’t handle. (It even tracked sometimes on the other near-impossible surface, a mirror.)

So, does this mean that the mechanical ball mouse has finally met its demise?  Well, unless you really want or need to use your mouse on a mirrored surface, the writing is definitely on the wall, especially when the technology spreads to cheaper mouse units (the Explorer retails for around $100).  Until then, if you are one of the dwindling number that use an old style mouse, enjoy cleaning out the fuzz while you can.

Toshiba readies LED pocket projector

It seems like we just had an article about a pocket projector from 3M (we did – literally).  So, for inquiring minds, and in an attempt to remain vendor neutral (whatever that is), we present another new projector, this time from leader Toshiba.

The Toshiba LED Pocket projector (also known as a pico projector, but that name just doesn't work as well for me) weighs in at 100 grams and measures 10 x 4.5 x 1.7 centimeters. Toshiba is reportedly readying it for market release, but little is known in the way of specs.  You can, however,  check out a video of it at this site

Given that it is an election year, I can hear the campaign slogans now: a chicken projector in every pot pocket…
