This giant-size version of Operation from Brian of the Lansing Makers Network was an enormous hit at Maker Faire Detroit. The game is played just like the original and uses scaled up pieces and kitchen tongs as tweezers. An Arduino detects any false moves and reports them to a computer running a custom Processing sketch. In addition to keeping score, the sketch also keeps track of the the fastest times, peak usage, number of games played and any other information Brian, a self proclaimed data fanatic, could think of. I was a bit disappointed that the ‘scare you to death’ buzzer of the original was left out. Maybe he could work that in on the even larger version he’s building for next year?

With a desire to find out how a deep display would look, video artist Blair Neal created the Crayolascope, a fantastic 3D depth display out of a dozen hacked Crayola Glow Books. An Arduino Mega is driving the display and the user can adjust the speed of the pre-drawn animation or scrub through the frames. The unconventional display was exhibited at The New York Hall of Science (home of World Maker Faire New York) as part of the animation exhibit and he says that it’s a big hit with kids. He also has a few plans for the next version:

I’d like to play with more powerful lighting and more full edge lighting, as well as solve the issue of internal reflectivity between panels degrading the quality of the “image”. Once the animation goes in about 14-18 frames, it becomes very difficult to see from one side unless it is in a very dark space. I would love to get it much deeper than that, or at least make a finer Z-space resolution.

[Thanks, Blair!]

Here’s some amazing work from maker Blair Kelly:

Arduino Wifly Mini is a remotely operated vehicle that communicates over a WiFi network, can be controlled with an XBOX 360 or PS3 controller, or G27 steering wheel, or any other controller that can be manipulated with Processing’s ProControll library, and features force-feedback and a first-person view. Presently only the G27 wheel and a Logitech F510 controller rumble properly with force-feedback.

My favorite part is that the point-of-view camera inside the car can be set to pan in the direction that you’re steering so that you can see where you’re going. I also love that he implemented force feedback to the controller triggered from sensors on the car. If you’d like to know how he did it all, boy are you in luck. Blair documented this project in incredible detail. Nice work!

Becky covered the first prototype of Instructables user marc.cryan’s homemade claw picker game about this time last year, when it was still just a two-axis machine in a doorframe. Now, Marc has added a third dimension, expanded the crane’s envelope to cover an entire room, and upgraded the business end with a SparkFun robotic claw. A universal TV remote serves as controller, communicating by IR with Arduinos in each of the two big motor housings.
