Raspberry Pi Banana Phone stops telemarketers and robocalls in their tracks
Right on the heels of the Raspberry Pi Model A announcement Monday morning, we came across an incredible phone hack that could make owning a phone a much more pleasant experience.
Alex Ruiz’s project uses a Raspberry Pi, an analog telephone adapter, and a switch to screen calls before they reach your phone and determine whether or not the call was made by a human or a machine. According to Lifehacker, the project only cost about $100 to put together. The program will intercept the call and ask the caller to listen for a randomly-generated series of four numbers to input manually in order to complete the call.
After the caller has been authenticated as a human, their number will be entered in the system’s whitelist so that your friends and family don’t have to repeatedly listen to the banana phone song before they can reach you.
Then again, I might turn off the whitelist feature when I get my hands on the Raspberry Pi. I sure hope we can record our own renditions of the song.
