Christmas is coming up quick. What are you going to get the person who wants useless things that look cool? Well, you are in luck, I found just what you need.
Polish engineer Paweł Zadrożniak has created a Bluetooth rotary dial smartphone. It’s a rotary dial from an old phone connected to a smartphone like it’s an external keyboard. A small battery runs the setup.
Unfortunately the rotary dial isn’t for sell. But, Zadrożniak does provide instructions and source code here on his blog so you to do it yourself. Watch the admittedly “useless invention” in action below.
