You have a smartphone that tells you when you have new emails, but do you have a shirt that does the same thing? Didn’t think so. You know who does, though? Two industrious modders known as Chris and Madeline. This husband and wife duo has created a t-shirt that lets you know when you have new emails.
It gets this done using an Arduino Lilypad microcontroller, a few LEDs, conductive thread, and a Bluetooth dongle. The result? A flashing light when your friends and family are letting you know what is up, or when an African prince lets you know you are about to be the proud recipient of a billion dollars.
