Rewiring a free carnival sign

Late last September, Hackaday along with other hackerspaces including North Street Labs, 1.21 Jigawatts, Maker Twins, made their way to the NYC Maker Faire via the Red Bull Creation contest. The objectives of the contest were simple: build a game in 72 hours, have people vote on it, and join the Red Bull crew in Queens for a carnival-like atmosphere.

When the Maker Faire was over, Red Bull had some leftover props from their Midway at Maker Faire setup, including a few illuminated carnival signs. Without any use for them, they graciously gave Hackaday, North Street, Maker Twins and the Jigawatts the signs to their respective rides.

Now that things have settled down and the rides have returned to their home base, the folks over at North Street decided to improve their sign. At Maker Fair, these signs were illuminated by 50 incandescent bulbs, all wired on the same circuit. [Steve] over at North Street had the awesome idea of adding a persistence of vision aspect to the sign, so work began on wiring every fourth bulb in series.

To drive the light circuits, North Street repurposed the Arduino Relay shield originally used for the lights on the Centrifury, their competitive centrifuge and spinning hell of a game. In the video after the break, you can see the addition of POV lights really brings out the carnival atmosphere. A literally brilliant build, and a wonderful addition to the scariest game ever made.
