Rock ‘Em Sock ‘Em Robot Costumes Make Party Conversation Awkward

October 31, 2012 by 4 Comments

Don’t get us wrong, we love these Rock ‘Em Sock ‘Em Robot costumes. But as with that Samus Helmet it must make party conversation a bit weird. And how do you hold on to your beer? But you’ve got to commend [EyeHeartInk] and his friend for their commitment. Not only did they wear them to the party, but they spent two months building the things.

Pretty much everything was made from cardboard. All of it was hand cut with a box cutter and a hobby knife. Duct tape and glue were the adhesives of choice, and according to this thread a total of fifteen rolls of tape were used. The half spheres on the side of either helmet were molded from expanding spray foam inside a ping-pong ball which had been lopped in half. And of course there are a pair of LEDs for the eyes of each bot.

We usually try to link to other articles that are related, but it doesn’t look like we’ve seen this concept before So you’ll have to settle for this non-Halloween wristwatch controlled robot boxing game.

 

Can You Believe This Portal Gun Was Built From Scratch?

October 31, 2012 by 13 Comments

This Portal gun will really make [aNoodleJMC’s] costume pop this year. She actually built the video game weapon replica from scratch. It even includes some electronics to light it up blue or orange depending on which portal she’s planning to fire at an available flat surface.

There’s a lot of parts that went into the project, but by far our favorite one on the list is an acrylic toilet plunger. Its handle serves as a light pipe for the colored LEDs and can be seen above as a cloudy rod at the center of the clear barrel. A 4″ and 3″ PVC pipe helped to form the rest of the barrel, along with a 3″ clear acrylic pipe for the transparent areas. The bulbous parts of the body were sculpted from florist’s foam. Once she had all of the parts roughed out it’s obvious that [aNoodleJMC] spent a ton of time filling problem areas with Bondo, sanding everything smooth, and giving it a paint job she can be proud of. We hope she didn’t forget to include GLaDOS in the fun.

We actually just bought our Portal gun. But that’s because we had the big plans of adding the ability to levitate objects.

Fembot Costume Includes Smoking Nipples

October 31, 2012 by 16 Comments

The greatest of Halloween costumes start with an idea, but they’ve also got to have strong execution to pull the whole thing off. This year  [Johanna Jenkins] decided to put together a Fembot Halloween costume which is a wonderful example of this concept. Going as a Fembot from Austin Powers: International Man of Mystery sounds like a lot of fun right off the bat, but a bit of work at the sewing machine and access to a wig shop in Hollywood really brought it to the next level. But [Johanna] didn’t stop at that. The Fembots have machine guns in their bras. After they’ve torn through all of their ammo they’re left with smoking barrels as nipples, and that final touch even made it into the costume. In the video after the break you can see [Johanna] showing off the small battery operated fog system she piped into the costume bra.

A Scary Pumpkin Pi

October 31, 2012 by 2 Comments

What do you get when you combine motion sensors , a Raspberry Pi, and a pumpkin? When it’s Haloween, a headless scarecrow with a light-up carved pumpkin in its lap! The execution of this hack is really great, and the resulting effect, as shown in the video after the break, should be extremely scary to any kids that come knocking.

One neat effect of this hack is that it uses X10 home automation modules to turn off the porch lights for an extra scary effect. After this, the jack-o-lantern lights up and says “help me!” If you’d like to duplicate, or build on this hack, instructions are provided as well as source code for everything on the page. While you’re there, be sure to poke around on [Insentricity] as there are quite a few other hacks available for your perusal! Don’t forget sure to send us any other Halloween hacks that you come up with.

Nyan Cat Hat Will Be The Hit Of The Party…. For About One Minute

October 30, 2012 by 26 Comments

Seriously, this Nyan Cat hat is the only part needed for a fantastic Halloween costume. It looks pretty good in this still image, but we dare you to watch the clip of it in action (embedded after the break) without letting a beaming grin creep onto your face. Everyone’s going to just love this… until it starts to get really annoying.

When switched on, the iconic meme rotates around the headgear, bobbing its head and tail as she sings the song of her people. There are also stars made of white LEDs that twinkle very brightly in the process. The presentation is quite good, but even better is seeing the build process. Luckily [Ben Katz] posted a series of detailed articles during the adventure. The mechanism responsible for driving the cat around the hat was laser cut from acrylic. It includes a large gear with teeth on the inside, which is interface by a continuously rotating servo motor with a much smaller gear. The head and tail bobbing are purely mechanical, using the revolving motion to turn a spindle as the cat makes its way around the brim.

Halloween Props: Monster In A Box

October 30, 2012 by 2 Comments

This furry Halloween decoration proves to be a simple build, but it’s still quite popular with the little ones. [Chris] had a Halloween party for a group of 2-5 year olds and this monster that peeks out of a box was a huge hit. The trick really isn’t in the complexity of the build, but in the interactivity.

The enclosure is just a shoe box which has been covered in synthetic black fur. The lid was hinged on the back, and a hobby servo with a bit of an extension on the arm is used to lift the front which reveals the monster’s paper eyes. Inside you’ll find an Arduino, breadboard, and battery pack. It’s not visible above, but a distance sensor on the front of the box is monitored by the Arduino. When it detects something in front of it the servo fires up and pops open the lid. The firmware includes a timer so that the monster waits a bit before taking its next peek at the party.
