Created by Tom Ward, this cool dot-matrix business card tells people more about you at the push of a button.
Ward made use of a five by 15 grid of LED lights that were connected to a single-chip “PIC” micro-controller. Some switches and resistors were used to complete the controller.
The business card is always on sleep mode, only activated at the push of the button.
It costs about US$5 to make, but some experience with electronics will come in handy.
