Small W-Fi detection devices aren’t new (check out this keyring Wi-Fi seeker), but I think this is the first time I’ve seen an everyday item with a Wi-Fi detector built-in, as is the case with this Wi-Fi detecting pen, spotted by our colleagues over at Shiny Shiny.
Press the button on the barrel, and coloured LEDs will indicate the strength of the Wi-Fi signal in the area. If the lights fail to show, you can use the pen with your trusty notepad and type it up later.
It’s available now at an affordable $19 (that’s around £10). Find out more about this over at Shiny Shiny.
