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”

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.

Alas, Poor Yorick! He Hath Not Amazon Prime

If you are looking around for a Halloween project, you might consider The Yorick Project from [ViennaMike]. As you can see in the video below, it marries a Raspberry Pi acting as an Amazon Alexa with an animatronic skull.

This isn’t the most technically demanding project, but it has a lot of potential for further hacking. The project includes a USB microphone, a servo controller, and an audio servo driver board. It looks like the audio servo board is controlling the jaw movement and based on the video, we wondered if you might do better running it completely in software.

Passwords? Just Use Your Head!

Biometrics–the technique of using something unique about your body as a security device–promises to improve safety while being more convenient than a password. Fingerprints, retinal scans, and voice identification have all found some use, although not without limitations.

Now researchers in Germany want you to use your head, literally. SkullConduct measures vibrations of your skull in response to a sonic signal. A small prototype was successful and is particularly well suited for something you are holding up to your head anyway, like a smartphone or a headset like a Google Glass.

There are some limitations, though. For one thing, background noise can be a factor. It stands to reason, also, that more testing is necessary.

This looks straightforward enough that you could try your own version of it. After all, scanning veins in your hand has been hacked. We’ve even seen a biometric safe.

Atomic skull clock reminds us we’re dying

atomic-skull-clock

Whether you like it or not, every second that passes brings you one step closer to your own demise. It’s not a comforting topic to dwell upon, but it’s reality. This art installation entitled ‘Memento Mori’ is a haunting reminder of just that. Even with all the advanced technology we have today, we still have absolutely no way of knowing just when our time will come.

[Martin] cast a real human skull, then added a 4 digit LED display that’s attached to a rubidium atomic clock (running a FE-5680A frequency standard). The display counts down a single second over and over, measured in millisecond-steps, from 1.000 to 0.001. He built a custom electronic circuit to convert the 10 MHz sine wave into a 1 kHz pulse signal, and used ATmega8 chips running an Arduino sketch to do the rest of the dirty work.

Watching the video after the break, with that smooth mysterious music in the background, one can’t help but ponder our mortality. On a personal note, this totally feels like something you’d find in a video game.

[Thanks Martin]

Dollar store Terminator replica

Okay, now we think [James] is just on a mission to see what he can build using the dollar store as his parts bin. This is the nearly finished replica of the cyborg skeleton from the Terminator franchise. It’s made mostly from things that cost $0.99.

Actually we’ve got that a bit wrong. [James] is really shopping at the £0.99 store but the concept is basically the same. He’s already shown us that he’s a pro at this with the arc reactor replica we recently saw from him. This time around a set of speakers donate their enclosures to build up the spinal column supporting the skull. Fittingly these are glued together using a hot glue gun from the store. The sides of the skull are carefully crafted from a set of four plastic bowls. The jaw comes together thanks to the corners of a plastic box’s lid. And finally the majority of the face is from a golden skull costume mask. Spray it all grey and pop in some LEDs for the eyes and he’s done it! He show’s off his final creation in the video after the break.

Halloween Hacks: Simple robotic skull is a perfect last minute decoration

If you haven’t taken the time to put your decorations together it’s time to get a move on. With Halloween just around the corner big elaborate displays are pretty much out of the question, but [Boris] and the team over at Open Electronics have a simple project that’s sure to be a hit with the Trick or Treaters.

Using a cheap plastic prop that you can likely find at any Halloween store, they have put together a simple talking skull that moves along with whatever music or sound is being piped through it. The skull’s mouth is moved by a single servo mounted inside the brain cavity, which is controlled by an Arduino. The Arduino monitors the sound level of the source audio being played, actuating the servo accordingly.

It’s quick, simple, and effective – perfect for a last minute decorating project. If you are a little more ambitious, you could always put together a whole chorus of skulls without too much additional effort – just a few extra skulls and some servos would do the trick nicely.

Check out a quick video of the skull in action below, along with another short clip showing how the servo is rigged up to move its mouth.
