We’re well past the time when Halloween costume submissions stop hitting the tip line, but like ever year we’re expecting a few to trickle in until at least Thanksgiving. Remember, kids: documentation is the worst part of any project.
[Troy] sent us a link to his wearable Game Boy costume. It’s exactly what you think it is: an old-school brick Game Boy that [Troy] wore around to a few parties last weekend. This one has a twist, though. There’s a laptop in there, making this Game Boy playable.
The build started off as a large cardboard box [Troy] covered with a scaled-up image of everyone’s favorite use of AA batteries. The D-pad and buttons were printed out at a local hackerspace, secured to a piece of plywood, and connected to an Arduino Due. The screen, in all its green and black glory, was taken from an old netbook. It was a widescreen display, but with a bezel around the display the only way to tell it’s not original is from the backlight.
Loaded up with Pokemon Blue, the large-scale Game Boy works like it should, enthralling guests at wherever [Troy] ended up last Friday. It also looks like a rather quick build, and something we could easily put together when we remember it next October 30th.
[Troy] wasn’t the only person with this idea. A few hours before he sent in a link to his wearable Game Boy costume, [Shawn] sent in his completely unrelated but extremely similar project. It’s a wearable brick Game Boy, a bit bigger, playing Tetris instead of Pokemon.
[Shawn]’s build uses a cardboard box overlaid with a printout of a scaled-up Game Boy. Again, a laptop serves as the emulator and screen, input is handled by a ‘duino clone, and the buttons are slightly similar, but made out of cardboard.
Both are brilliant builds, adding a huge Game Boy to next year’s list of possible Halloween costume ideas. Videos of both below.
Impatient Severed Fingers – [Amanda] came up with a cute use for some mini servos and a zombie hand prop. The five severed fingers were attached to one end of a plastic rod. The other end was mounted to each of five servos which were laid out in the appropriate hand shape and attached to a fixed base. An Arduino running a basic sweep sketch animated the motors at slightly staggered intervals, creating a nice rolling effect. Even with the moving parts exposed this prop would be awesome to have on display, or set the ambiance with its continuous tapping…
Angry Spectral Delta – [Nathan Bryant] made an actual costume for his delta robot from Robot Army. By attaching a small plastic skull to the end effector and draping a tattered piece of fabric over the rest of the mechanism he effectively transformed the delta into a little ghost with a sassy personality. The head swiftly bobbed about, all while staying parallel to the table… until it intermittently came unhinged and hung limply, which was a nice added effect!
Robotic Exorcism Baby – This doll could turn its half skeleton, half baby face 180 degrees and then laugh at your fear. By attaching two servo motors together, [Jeremy] was able to create a pan and tilt mechanism which acted as the baby’s contorting neck and chattering jaw. The micro controller sending commands to the motors was hidden modestly under her dress.
Stabby Animated Cardboard Shadowbox – Among the animatronic devices seen at the event was a shadowbox made by [Brandon] hidden in a dark conference room nearby. When one happened to walk past the seemingly unoccupied space, they’d glimpse the silhouette of an arm stabbing downward with a knife through a windowsill. Being lured in for further investigation you’d find that the shadow was being cast by some colored LEDs through a charmingly simple device. A cutout made from recycled card stock was attached to a single servo. This whole mechanism itself rocked back and forth slightly as the motor moved, which wasn’t intentional but added some realism to the motion of the stabby arm.
[Atom] is using a few interesting components in this build.
