[Scott Holden] went all out this year and built an amazing Tauntaun costume. The Tauntaun from Star Wars was massive, standing 8 feet tall, and usually carrying a rider. [Scott] wanted to make it the correct size, and ultimately pulled it off. He had to build custom stilts to get the leg angle correct as drywall stilts were too straight. The rest is mainly pvc and fur. We think he did a fantastic job on this. The effect is quite nice, and we can imagine that in person it is even better.
Take note at the bottom of page 3. Apparently, he got pinned in the costume in his workshop and almost had to spend the night on the floor in the costume. That’s pretty wild, at least he was warm.
Halloween is this weekend. If you still have some time and parts available, you might be looking to spice up your Jack-o-lantern. We’ve found a few projects that we thought might be nice to share. None of them would merit a post on their own, so we thought we would just round them up and share them all at once. They all appear to be powered by the Arduino, which we know will bring some comments. Just to clear up some questions, they don’t pay us to advertise Arduinos. People just do a lot of projects with them.
First, the silly string shooting Jack-o-lantern which you can see above. He’s using a single servo hooked to an Arduino and a motion sensor. When it detects motion, it lets out a short squirt of silly string. You can download the code from the project page. We might suggest you arrange this in a manner to avoid spraying directly into some kids eyes.
If you’re wanting to spice up a Jack-o-lantern, why not give it some spooky eyes that will look around? [todbot] shows us how to set this up using an Arduino and 3 servos. His rig uses a hobby servo to control the entire head’s orientation and a smaller servo for each eye’s movement. Their motion is random, but quite convincing. He has them all stuck together with popsicle sticks, but you would probably move the location of the large servo to rotate the entire pumpkin, or whatever other prop you put it all in. You can download the Arduino sketch and give it a try your self. We might suggest building a simple rack and pinion rig to rotate both eyeballs with a single servo.

Would you like some spooky glowing eyes that light up and play a sound when someone gets near? This circuit makes it pretty simple. It uses a single phototransistor to detect someones presence. Instead of having a preset threshold that needs to be met, it simply triggers any time there is a sufficient change in the amount of light it detects. If you put one of these in a nice dark spot, your halloweeners will only see the LEDs and perceive them as eyes. It might also be cool to somehow add motion to this.
We’re running out of time to prepare for Halloween, don’t forget to send in your projects.
[Garret] and a couple of friends totally stole our idea wanted to light up their pumpkins a bit differently this year. They used some ShiftBrites and all the corresponding shift hardware (who knew there was so much shift out there) to bring their carved orange minions to life. Yes, this could be done a lot less modulated by using a regular LED and perhaps a PIC. Maybe it’s not the most technically challenging, but hey its in the spirit of Halloween – one of our favorite holidays. Speaking of which, doesn’t that fence look familiar? Check out a video after the break. Seriously, Mutton Chops? Read the rest of this entry »
Halloween is on its way, and if you’re going to do it right, you’re going to overdo it right. A few days ago we showed you [Jake's] flying Crank Ghost, the idea is simple and creates lovely motion that is sure to scare some small children. But what if you want people leaving your little shop of horrors needing a new pair of pants? Meet the Animatronic Winged Demon by [Woody]. Very little info is given except for the touch screen controller, the central control system, and his unique use of a modular skeleton, but the project is very impressive none the less. If the demon doesn’t scare you, take a look at the miles of wires needed to control it. Check out a video after the break.
Grid beam is a prototyping and building medium that’s like a giant hippie Erector set. You can’t buy grid beam, but with a drill press, a jig, and some square stock you can create your own unlimited supply. It’s ideal for “sketching” and temporary constructions like these Halloween props. After use, everything can be dismantled, stored flat, and later reused for the next [Herbie Hancock] music video creative project. Looks like fun!
The article wraps up with some valuable pointers on getting started with grid beam and where to acquire parts.
Halloween is a scary time for the little ones. It’s dark, they can barely see through their injection molded Spiderman masks, but it’s all worth it for the candy.
Our friends over at Evil Mad Scientist Labs have produced a pumpkin that moves on its own. The little pumpkin was disemboweled from the bottom and its guts were replaced by a simple robot. Three Lego wheels provide this base with one attached to a continuous rotation servo that provides the motion. The device is powered by 3 AAA batteries and powered by an Atmel ATtiny2313 microcontroller. For added terror there are two green LEDs that act as ghoulish eyes.
We’ve embedded the video of the Rovin Pumpkin in action after the break. This is a wonderfully simple way to spice up your front porch decorations on All Hallows’ Eve. Read the rest of this entry »
[Backroads] has put together this nicely detailed writeup explaining how to make a low cost popup prop. He’s using a single pneumatic valve and a home made PVC piston to raise and lower a scary mask. He’s using an off-the-shelf 110v AC valve controller to control the valve. A flickering light, a “screamer” and a fog machine help fill out the project. The result is quite nice. We would be tempted to put a pressure sensor in front of it to optimize the scare timing.
