Arc Reactor replica could have been crafted in a cave


Following in the footsteps of [Tony Stark] this Arc Reactor replica was hand crafted using almost no power tools. From what we can tell in his build gallery, a cordless drill was his only departure from using pure elbow grease.

[DJ Maller] started his build by cutting out a disc of acrylic for the base plate. While we might have reached for a hole saw, he grabbed a framing square and laid out a center point and square cuts on the stock. Kudos for his use of an awl (we often take the Luddite approach of hammer and nail) to make an impression for his compass point to rest in. After using a coping saw to rough out the shape he sands the round up to the line with the drill and a sanding wheel.

After drilling holes and inserting LEDs he begins to build up the replica piece by piece. What looks like a recessed handle for a sliding closet doors makes up the center. The spring-like copper coils was produced by wrapping wire around a pen then stretching to the desired shape. He added a bicycle spoke wrench wrapped with copper for some additional visual appeal before finishing the decoration off with some storm door clips.

Roomba and virtual walls make up this theme family Halloween costume

It figures. You spend a ton of time making a cool set of costumes and then you can’t get your kid to pose for a picture. It’s okay though, we still get the point. This themed set of costumes dresses the little one as a Roomba vacuuming robot while mom and dad are suited up as virtual walls (modules that are used to keep the bot from falling down stairs, etc.). It’s fun and unique, but had it not been for some additional electronics this would have been relegated to a links post. For safety sake each costume was outfitted with a ring of LEDs. As a challenge, the lights were given the ability to sync up patterns with each other.

Each costume has a circular frame at the top with a set of RGB LED strings attached. To get them to display synchronized patterns an IR transmitter/receiver board was designed and ordered from OSHPark. Each costume has four of these modules so no matter where the wearers are facing it should not break communications. A demo of the synchronized light rings can be seen after the break

Rock ‘Em Sock ‘Em Robot costumes make party conversation awkward

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?

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

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.

Ironman replica twofer

We think it’s a bit to late to show up for a screening of The Avengers in full costume, but an arc reactor T-shirt would be pretty cool. [4ndreas] built a chest strap that looks much like [Tony Stark’s] chest-mounted power source. It has a 3D printed enclosure which hosts the ATmega8 and 22 LEDs which provide the pulsing goodness. The thin cellphone battery helps to keep the size of the package to a minimum and a strategically placed hole in a black T-shirt completes the look. It’s even bright enough to shine through the fabric of this black T-shirt.

But if you insist on head-to-toe regalia you’ll appreciate [James Bruton’s] Ironman suit replica build. Not only does he look the part, but he’s trying to build as much functionality into the project as possible. Most recently he finished the helmet. It’s got a motorized faceplate and LED edge-lit eye plates to impress hackers and cosplay fans alike.

Find video of both projects after the break.

Worried about Haloween this Year? Why not a Giant T-Rex Costume?

Although some might note that [Jamie]’s creation could mistaken for a Velociraptor or even Allosaurus, his giant T-Rex costume/model is quite a feat of artistry. It stands at over 14 feet tall and 10 feet long. For comparison, the room that you see in the picture above measures 25 x 25 feet. If you happen to live in the Atlanta area, or are willing to travel, this costume is expected to make an appearance at Dragon*Con in 2012, so be sure to look for it there.

The whole thing is made from poly foam plank cut with a CNC router.  It also has a metallic support structure. As noted in the article, you could, in theory, cut all these parts out by hand. Persistence would be required though, since there are over 140 parts!

[Jamie]’s making capabilities are obviously quite advanced at this point, but he’s trying to expand them by winning a router in the Instructables Shopbot contest. If you like his creation, be sure to vote for him! Check out the video of this costume in action after the break. Continue reading “Worried about Haloween this Year? Why not a Giant T-Rex Costume?”
