Engineer makes light-up business cards with 555 timer, proves PCB skills
Sure, there have been some pretty creative variations on the standard paper business card, but if you're looking to make a career in electronics engineering, card stock isn't necessarily the best option for material. Such was the case for one student, who had the canny idea to make a card that demonstrates his printed circuit board know-how. He used a 555 timer that outputs a clock to the LEDs on the biz card, and placing a nine-volt battery on the terminals sets off the mini light show. See for yourself in the video below.
