This isn’t the first circuit board business card we’ve seen, but this one is more useful than others. Its maker, Saar Drimer calls it the Engineer’s Emergency Business Card. He makes a living from making circuit boards, so this was probably a piece of cake for him.
You can’t plug it into your computer, or even open a beer with it, like other cards we’ve seen. But not only does Saar’s card light up when current is applied to it, it’s cleverly designed so its two resistors, LED, NPN MOSFET, capacitor, and even a little extra bit of solder can be easily removed for emergency use.
When all hope is lost, the MacGyver 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!
How brilliant is this?
