Portal…shirt?

October 26, 2010 by Jakob Griffith 29 Comments

[Ben Heck] is in the Halloween spirit with his Portal inspired “see through” t-shirt. That is, a thin lcd is mounted on [Ben’s] chest, with a not as thin camera mounted on his back; when the system is running, everything behind him is captured by the camera and displayed on the LCD. The concept isn’t exactly new by any means, often by the name of “gaping holes” or “hole through body” or more, but the project goes to show that a creative costume isn’t always the most elaborate, expensive, or even a new idea. Catch a video of how to make your own Portal shirt, after the jump. Oh, and you can win the Portal shirt here.

Creepy HDD Activity Lights Just In Time For Halloween

October 11, 2010 by Caleb Kraft 23 Comments

We almost skimmed right past this spooky HDD activity light thinking it was just another set of LEDs wired to the motherboard. However, they explained right off that they didn’t want just another blinking light on their case. They wanted it to change its intensity smoothly based on hard drive activity. While there are a million ways this could have been over engineered, we think they did a pretty good job of simplifying the circuit. The bill of materials is pretty much just a handful of resistors, LEDs, an opto isolator, and a capacitor. The effect, is quite nice and can be seen in the video after the break.

Something Wicked This Way Comes

September 21, 2010 by Caleb Kraft 5 Comments

Halloween is rapidly approaching. This is just a reminder to you all to send in your Halloween hacks now so that we can all see them and steal your ideas get inspiration for our own projects. We’ve seen fantastic stuff in the past from motorized pumpkins to costumes that are simply awe-inspiring. Take a few moments to dig through the Halloween hacks we’ve run in the past.

Of course we understand that some of you will be pushing up to the big day to complete your projects. Just remember to take good pictures and document it all well.

20-channel DMX Controller

July 23, 2010 by Mike Szczys 29 Comments

[Joshua] shares his details on building this 20-channel DMX controller. He’s sourced some extension cords to cut up for the complicated wiring project. He plans to drive 120V lights with the system so he’s also using the extension cords to connect a bunch of outlet boxes to the main controller. Inside you’ll find a set of AVR chips ready for your commands. Instead of using jumpers or DIP switches to set their addresses he set them in the firmware and burned a different version to each chip. The key here is writing the address right on the chips to prevent any confusion.

This will be used of Halloween and Christmas displays. We love Halloween hacks just about as much as we love Christmas hacks, so hit the basement and don’t forget to share the result of your labors with us.

Tauntaun Costume

[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 Props: Techy Jack-o-lanterns

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.

Check out the next two after the break.

Halloween Props: Servo 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.
