We’re pretty sure that [Luke] took Uncle of the Year last Halloween when he made an RGB LED princess dress for his niece. He recently found the time to document the build with a comprehensive how-to that’s just in time for Halloween ’17.
[Luke] made the system modular so that his niece could use it with any dress. The RGB LED strips are actually fastened down the inside of a petticoat — a fluffy, puffy kind of slip that’s worn underneath the dress. The LEDs face in toward the body, which helps diffuse the light. [Luke] first attached the strips with their own adhesive and then spent a lot of time sewing them down so they stayed put. At some point, he found that hot glue worked just as well.
The coolest part of this project (aside from the blinkenlights of course) is the power source. [Luke] used what he already had lying around: an 18V Ryobi battery pack. He wired a step-converter to it using a printed cap from Shapeways that’s designed to connect metal clips to the battery contacts. This cap really makes these packs useful for a lot of projects that need long-lasting portability.
These batteries are rated for 240W, which is overkill considering the load. But there’s a reason: it keeps heat to a minimum, since the electronics are hidden inside a cute little backpack. Speaking of cute, you can see his niece model the dress after the break.

Halloween may have come and gone, but [Luis] sent us this build that you’ll want to check out. An avid Walking Dead fan, he put in some serious effort to an otherwise simple bloody t-shirt and created this see-through “stomach shot” gunshot wound.
The project uses a Raspi running the Pi Camera script to feed video from a webcam on the back of his costume to a 7″ screen on the front. [Luis] attached the screen to a GoPro chest harness—they look a bit like suspenders—to keep it centered, then built up a layer of latex around the display to hide the hard edges and make it more wound-like. Power comes from a 7.4V hobby Lipo battery plugged into a 5V voltage converter.
After ripping a small hole in the back of his t-shirt for the webcam and a large hole in the front for the screen, [Luis] applied the necessary liberal amount of fake blood to finish this clever shotgun blast effect.
Hackaday writer [Ryan Fitzpatrick], aka [PlatinumFungi], recently put together this amazing Metroid Power Suit helmet as a prop for a [Mike n Gary], on youtube. How amazing is it? This image is an actual photograph of the helmet! It’s being modeled by [Kelly Johnson], who built a power suit costume for a previous Halloween. But she never made a helmet, which makes sense to us. After all, how are you supposed to talk to anyone while wearing a helmet? Practicality aside, it is a delight to walk through the fabrication process.
[Ryan] started with a motorcycle helmet, making paper templates based on images from the game. After he had a reasonable road map for the work that needed to be done he started cutting away the parts which he didn’t need. The ‘beak’ on the front was then fabricated from paperboard, with the fins on the side sculpted from rigid foam. But there’s still a lot of work to be done from that point. Sure, the internal lighting and colored visor are necessary touches, but it’s the paint job and ‘distressing’ steps that make this look so realistic.
Looks like we’ve exceeded his bandwidth due to the tons of pictures he had of the process. Check out the video after the break.

From a small-sized backpack these wings slowly grow to full size in a Steampunk costume that hearkens back to DaVinci flight designs.
The mechanism that unfolds the wings was fashioned from parts of a baby gate and an old back massager. The massager features a pair of orbs that are meant to move slowly up and down your back. This is what accounts for the slow unfurling of the wings. After a bit of prototyping with Popsicle sticks [Dannok] and his daughter figured out the best arrangement for the pivoting skeleton. From there, the slats from the baby-gate were used to build the frame, then covered with fabric to finish the wing element for this Halloween costume.
A 12 volt gel battery powers the device, which is activated with a brass pull-chain meant for a light fixture. Once full extended, as seen above, the wingspan is eight feet. Don’t miss the pair of videos we’ve embedded after the break which show the workings of the device.

What happens when an unemployed sailor has a ton of time on his hands? Well, evidently they become an extremely skilled prop builder. Then again our only reference point is [Throssoli]’s excellent Dead Space suit build.
[Throssoli] started this ambitious project by setting a months deadline for the helmet. Although he did not meet the dead line the results were fantastic and very true to the game models. Noting the reaction people had to the helmet out in the wild, and giving in to the fact that he really wanted the full engineering suit as seen in game, [Throssoli] set off to reproduce the entire RIG down to the illuminated face mask and back mounted spine-like health and stasis indicators. All it really needs are lead weights in the boots to give it that signature stompy Isaac feel. The build incorporates a lot of techniques we typically see in other game related prop builds, such as the black-washing and weathering effects seen in the wheatley puppet and mold making as seen in this Portal Turret build and even daft punk helmets. Keep in mind [Throssoli] is no stranger to prop or suit building, his portfolio of finished projects include halo armor and props, various Star Wars costumes, Mass Effect stuff, a Predator outfit you name it. We could easily loose half a day just perusing all the builds at the site so check it out for yourself!
An accidental radial engine
Hack A Day’s very own [Jeremy Cook] was trying to figure out how to push four ‘arms’ out one at a time. What he came up with is a very nice model of a radial engine. Everything was cut on a CNC router and a motor from an air freshener provides the power.
Using a candle to produce light
[Chris] sent in his Candela Amplifier. It’s a Pentium 4 heat sink with a very bright Cree Xlamp LED attached to the base. A bunch of Peltier thermoelectric units are attached to the underside of the heat sink. Put the whole thing on top of a candle, and you can light a room. With a candle. Oh, he’s selling these, by the way.
Objectification and video games?!
We really feel sorry for our lady readers. Guys have so many choices for Halloween costumes, but just about every costume available for women can be reduced to, “Sexy [noun].” Whelp, here’s the Sexy Game Boy, just in time for Halloween. [kazmataz] gets a few bonus points because she went with the DMG-01. It’s better than Sexy Chewbacca, so she’s got that going.
Prototypable 32-bit uCs
[Ng Yong Han] wrote in to tell us about some newish 32-bit PICs that are floating around. The datasheet for the PIC32MX1xx/2xx chips is pretty interesting – USB support and an audio and graphics interface. Oh, they come in PDIPs for ease of prototyping as well. We haven’t seen much from the PIC microcontroller faction recently (Atmel is winning the holy war, it seems). Anybody feel like building something with these?
Makerbot dual extruder
[Lomo] at TU-Berlin is taking a class in rapid prototyping. He built a second print head for his department’s Makerbot Cupcake with a few other students. The result are pretty impressive, although from what we’ve seen, it’s generating the G-code that’s a pain in the butt.
