Business Card Lights Up When Touched

Designed by electrical engineering student Jay Kickliter for a job fair at his school, this capacitive-touch business card stands out from the standard issue. The card features a ring of LEDs that light up when it's touched, making it impossible to ignore.

Gizmodo notes that it was designed and manufactured in just two weeks. The card's parts cost just $2, and the board was around $8. It's a pricey investment -- $10 for just one card -- but it's one that is sure to get attention.

The source code, design files and schematic for making the card are available for download from Kickliter's site. You can check out the flashing business card in the video above.
