Business Cards That Light Up
Electrical engineering student Jay Kickliter designed this capacitive touch card, which has LEDs that flash when you hold it.
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 parts for the card came to $2 and the board was almost $8, making it a pricey investment, but one that is sure to get attention. The source code, design files, and schematic for making the card are available to download from Kickliter's site. You can check out the flashing business card in the video below:
