Ghost Rider Costume Is Smoking Hot

It’s that spooky time of year once again, with pumpkins and cobwebs as far as the eye can see. This year, [Mikeasaurus] has put together something really special – a Ghost Rider costume with some amazing effects.

The costume starts with the skull mask, which started with a model from Thingiverse. Conveniently, the model was already set up to be 3D printed in separate pieces. [Mike] further modified the design by cutting out the middle to make it wearable. The mask was printed in low resolution and then assembled. [Mike] didn’t worry too much about making things perfect early on, as the final finish involved plenty of sanding and putty to get the surface just right. To complete the spooky look, the skull got a lick of ivory paint and a distressed finish with some diluted black acrylic.

With the visual components complete, [Mike] turned his attention to the effects. Light is courtesy of a series of self-blinking LEDs, fitted inside the mask to give the eye sockets a menacing orange glow. However, the pièce de résistance is the smoke effect, courtesy of a powerful e-cigarette device and an aquarium pump. At 225W, and filled with vegetable glycerine, this combination produces thick clouds of smoke which emanate from the back of the wearer’s jacket and within the skull itself. Truly stunning.

[Mike] reports that the costume is scary enough that he has been banned from answering the door as Ghost Rider. We think it’s bound to be a hit, regardless. For another epic mask build, check out the Borderlands Psycho. Video after the break. Continue reading “Ghost Rider Costume Is Smoking Hot”

3D Printing, Halloween Style

The wonders of 3D printing don’t stop coming. Whether it’s printing tools on the International Space Station, printing houses out of concrete, or just making spare parts for a child’s toy, there’s virtually nothing you can’t get done with the right 3D printer, including spicing up your Halloween decorations.

Not only is this pumpkin a great-looking decoration for the season on its own, but it can also transform into a rather unsettling spider as well for a little bit of traditional Halloween surprise. The print is seven parts, which all snap into place and fold together with a set of ball-and-socket joints. While it doesn’t have any automatic opening and closing from a set of servos, perhaps we will see someone come up with a motion-activated pumpkin spider transformer that will shock all the trick-or-treaters at the end of this month.

It’s not too late to get one for yourself, either. The files are available on Thingiverse or through the project site. And we’ve seen plenty of other Halloween hacks and projects throughout the years too if you’re looking for other ideas, like the recent candy machine game, a rather surprising flying human head, or this terrifying robot.

Just in Time for Halloween: Another Talking Skull

It isn’t a unique idea, but we liked [Eric Wiemers’s] take on the classic animated skull for Halloween. In addition to showing you the code and the wiring, the video spends some time discussing what the audio looks like and what has to happen to get it into a format suitable for the Arduino. You can see the spooky video, below.

Of course, this is also a 3D printing project, although the skull is off-the-shelf. We wondered if he felt like a brain surgeon taking the Dremel to the poor skull. To fix the two parts of the device, he used brass threaded inserts that are heat set, something we’ve seen before, but are always surprised we don’t see more often.

Flying Human Head Lands Just in Time for Halloween

We love the fall here at Hackaday. The nights are cooler, the leaves are changing, and our tip line starts lighting up with some of the craziest things we’ve ever seen. Something about terrifying children of all ages just really speaks to the hacker mindset. That sounds bad, but we’re sure there’s a positive message in there someplace if you care to look hard enough.

Today’s abomination is a truly horrifying human head quadcopter, which exists for literally no other reason than to freak people out. We love it. Created by [Josh] and a few friends, the “HeadOCopter” is built around a meticulously detailed 3D print of his own head. This thing is so purpose-built that they didn’t even put landing gear on it: there’s no point sitting on the ground when you’re in the business of terrorizing people from above.

Sure, you could do this project with a cheap plastic skull. But there’s no way it would have the same effect. [Josh] created this monstrosity by scanning his own head with the Microsoft Kinect, cleaning the model up in ZBrush, adding in mounts for hardware, and 3D printing the result. After doing some smoothing and filling, the head got passed off to artist [Lisa Svingos] for the final painting. He even thought to include an FPV camera where one of his eyes should be, giving a whole new meaning to the term.

As for the quadcopter hardware itself, it uses a BrainFPV RADIX flight controller (get it?) and 12×5 props on Sunnysky V3508 motors with 30A BLHELI ESCs. Measuring 1 meter (3.2 feet) from motor to motor, it’s an impressive piece of hardware itself; head or no head.

This project reminds us of the flying ghost we saw years back, but we have to admit, this raises the bar pretty high. We’re almost afraid to see what comes next.

Arcade Inspired Halloween Candy Dispenser

The days are getting shorter and the nights are a little cooler, which can only mean one thing: it’s officially time to start devising the trials you’ll put the neighborhood children through this Halloween. For [Randall Hendricks], that means building a new candy dispensing machine to make sure the kids have to work for their sugary reward. After all, where’s the challenge in just walking up and taking some candy from a bowl? These kids need to build character.

[Randall] writes in to share his early work on this year’s candy contraption which he’s based on a popular arcade game called “Goal Line Rush”. In this skill based game a disc with various prizes spins slowly inside the machine, and the player has a button that will extend an arm from the rear of the disc. The trick is getting the timing right to push the prize off the disc and into the chute. Replace the prizes with some empty calorie balls of high fructose corn syrup, and you get the idea.

There’s still plenty of time before All Hallows’ Eve, so the machine is understandably still a bit rough. He hasn’t started the enclosure yet, and at this point is still finalizing the mechanics. But this early peek looks very promising, and in the video after the break you can see how the machine doles out the goodies.

The disc is rotated by a high torque motor, and the aluminum extrusion arm is actuated with a gear motor and custom chain drive. Some 3D printed hardware, a couple limit switches, and a pair of relays make for a fairly straightforward way of pushing the rod out when the player presses the button on the front of the cabinet.

Considering how his previous Mario-themed candy dispenser came out, we doubt this new machine will fail to impress come October. The neighborhood kids should just count themselves lucky he’s not using his creativity to terrorize them instead.

Mario Candy Machine Gamifies Halloween

Picture it: Halloween, 2018. You want to go to a party or take the kids out trick-or-treating, but remember what happened last year when you weren’t there to answer the door? A pack of wild children blew their allowances on 48 rolls of the cheapest toilet paper ever printed, and it took you four full hours to get all the sodden, dew-laden wads out of your rose bushes.

Halloween is a time to fear things like hobgoblins and the possibility of The Purge becoming a thing, not sugar-fueled children who are upset that you left out a bowl of Sixlets, wax lips, and alt-flavored Tootsie Rolls. So how do you take back the night? Do what [Randall Hendrix] did: build a Super Mario-themed candy-dispensing machine.

No customer, not one tiny [Thanos] or [Tony Stark] will be able to resist the giant, blinking, green start button. Pushing it cues the music and the spinning drum, which tumbles the candy around like a clothes dryer. Gravity and chance will drop one or three pieces onto a conveyor belt that runs under Mario’s feet, but it’s up to you to press the jump button at the right time.  Otherwise, he knocks your prize back into the barrel.

There’s no micro here, just woodworking, relays, motors, a sound FX board, and the amp from an old pair of PC speakers. Mario’s candy-securing jump was originally pneumatic, but now it’s powered by a 240:1 gear motor that lifts him up with a cam. Grab a fun size Snickers and slap that break button to see this marvelous machine in action.

Concerned that they’ll play until the candy is gone? Add a sinister element like the Candy-or-Death machine we saw a few years ago.

Parts Bin Spooky Eye Build

Halloween is a great holiday for hacks, bringing out the creativity in even the most curmudgeonly wielder of a soldering iron. [tdragger] was looking to have some good old fashioned Halloween fun, and got to thinking – putting together this great Spooky Eyes build in their attic window.

The effect itself is simple – just two glowing orange LEDs spaced the right distance apart, placed in the highest window in the house. As every young child knows, the attic is almost the spookiest room in the house, second only to the basement.

Various effects were programmed in to the Arduino running the show, like breathing and blinking effects, to give that frightful character. For maintenance and programming purposes, [tdragger] wanted to have the Arduino remotely mounted, and searched for a solution. Rather than leaning on a wireless setup or something modern and off-the-shelf, instead some old RJ11 telephone extension cables were pressed into service. These allowed the eyes to be placed in the window, allowing the Arduino to be placed in a more accessible location.

It’s a basic project, but one that has a good fun factor. Sometimes it’s good to use what you’ve got to hand, so that the buzz of enjoyment isn’t dampened by the long wait for shipping. For something bigger, check out this giant staring eyeball.
