You’ll be the center of attention with this little gadget which lets you wear your own miniature LED scrolling sign board.
The $39 Infrared LED Name Badge is a tiny version of those scrolling signs you see all over the place. It’s got an array of 12 x 40 LEDs which can be programmed wirelessly via an infrared transmitter which connects to your computer’s USB port. The included software lets you create messages in a variety of fonts, and also include images and set scroll direction, speed and other effects just like its larger cousins.
If you’d rather not spend 39 bucks, check out these LED dog tags, which cost about half as much, but don’t offer as much programmability.
