I wasn’t at Maker Faire setup day for more than a few minutes before I ran into Limor Freid of Adafruit awesomeness and Windell Oskay of Evil Mad Scientist Labs, well, evilness. I’m honored to have received from each of them truly unique and wonderful calling cards.


These are quite a bit more functional than your average card. Limor’s is a working Spirograph with bonus rulers at the edges. EMSL’s is a Tiny 2313 prototyping board. I was hoping to declare a winner on Sunday of Bestest Maker Faire Calling Card, but may need to chicken out and have winners both in the Mechanical and Electronic divisions! Anyone else done up a super rad card?

    What awesome calling cards! I would love a spirograph one from Limor.

    I’ve got one that’s an “impossible object” card — sorry, no pictures handy.

    Although these easily take the cake, I like our own Jerome Demer’s concept of a resistor bender built into his card. We actually put it to good use today while getting some devices ready for our booth here at the Maker Faire today.

    Look for the guy in the Solarbotics jacket with crazy patterns shaved into his beard. That’s him!

      I wish I’d seen Jerome’s resistor bender card!
