An Engineer’s Emergency Business Card

breakout_3

We’ve seen lots of circuit board business cards before, but none quite like this. [Saar] calls it the Engineer’s Emergency Business Card.

Since he actually makes a living from making circuit boards, it made sense for him to make a truly functional card. But unlike some of the fancier cards we’ve seen, you can’t plug it into your computer, or even open a beer with it! In fact, all it does is light up when a voltage is applied across the main pins.

But wait — why are all the components in through holes? Well, according to [Saar], that’s because it’s designed to be the electrical engineers emergency kit!

When all hope is lost, the MacGuyver engineer could snap out one of the components and save the day. Recall the countless times you desperately needed a 1 KOhm resistor to fix an amplifier at a party, only to see the girl you were trying to impress slip away with an OCaml programmer? Never again with this little kit. You even have 2 cm of solder in there to make sure the connection’s electrically solid!

We love it. Whether or not anyone will ever successfully use it in an emergency situation such as [Saar's] hypothetical one is another question altogether. But we do have to give him creativity points for it, the artistic traces look awesome!
