Dot Matrix Business Card

In most settings business cards are given out without much thought. But what if you could make your card stand out from the rest? By using a 5×15 LED matrix screen, a single micro controller, a number of resistors, switches, and other parts, [tomward] has put together one very slick business card that’s sure to draw attention.

The included instructions go into great detail on the construction, but [tomward]admits that you will need some knowledge in electronics in order to build one yourself.  After reading the instructions ourselves we would have to agree with him.

If you’re into programing micro controllers and are handy with a soldering iron you may want to give this a shot.
