WiFi Detector Shirt by ThinkGeek will help you monitor your wireless connection in your dorm room and around campus. The shirt lights up to indicate when you have the best signal strength.
WiFi shirt needs 3 AAA batteries, and is actually cool. the cable is a little annoying around the stomach, but its a great buy!
Just remember, its a wifi detector shirt, but it is actually a big black patch. its great and works, but can be easily disapointing. It only searches for broadcasted networks, not for hidden ones. also, it cant tell wether or not the wifi is passworded or not.
With an almost exponential growth in the number of hotspots around the world, the need for quick, simple, and cheap Wi-Fi detectors is clear. These small devices, ranging in size from a key chain to a small cell phone can detect the 2.4Ghz signal from a Wi-Fi source and alert the user to its presence and the signal’s strength. Some Wi-Fi detectors, like this WiFi Seeker from PCTEL, are directional. This means they let you know which direction the signal is coming from, helping you detect the hotspot faster. Other devices, such as the ACW20US WiFi Scanner from Targus, can identify multiple access points and inform you what their status is (secure / unsecured), an important function when looking for open access points.
A DIY attempt to create a Wi-Fi detector embedded into a backpack strap was recently reported by “Make” Magazine. Although the concept seems more practical than the Wi-Fi detector shirt, it will be hard to call it fashionable. The Wi-Fi Detector T-shirt, however, is more appealing (if you are into that sort of geeky look). Still, we can’t help wondering how silly you will look, walking around staring at your shirt all day.
