With the extraordinary increase of the demand for mobile computing systems (and thus, also of the number of such devices), WiFi networks have also become quite popular. One on the most serious problems faced by the users of such networks is that of finding an area where the signal is strong enough to allow a decent connection to the Internet. That's exactly the reason why all sorts of devices that indicate the quality of the signal have been developed, one of the most interesting being the WiFi Pen.

The device is quite user-friendly, since it works by simply pressing a button, and, depending on the signal's intensity, a Green/Yellow/Red LED lights up. The device has a detection range of up to 15 meters and features a white LED at the top, which can be used as some sort of pen-lantern. And, quite surprisingly, it can also be used for writing.

The WiFi Pen could prove to be quite a successful gadget, partly for the reasons listed above, but also because it's so versatile, featuring some pretty interesting functions and, most importantly, quite a cool-techy look, which is sure to attract the people who love this kind of devices (and trust me, there are quite a lot of them out there, yours truly included).

We are just a few, but there are many of you, Softpedia users, out there.
