Singing House Lights Up Halloween Again This Year

October 25, 2011 by 19 Comments

[KJ92508] is flooding the neighborhood with light again this year. Everyone knows of that one house in town that really goes all out, but few put on a show anything like this one. The four Jack-o’-lantern faces lead the way with the opening sequence from A Nightmare Before Christmas. Each has at least four different mouth poses, and two eye orientations which are surprisingly well synchronized with the audio. The image above shows mostly orange lighting, but the home is outfitted with addressable RGB LEDs for a full color performance. In fact, it has seen an upgrade this year, increasing the channels by eight-fold to 1144! Don’t miss the performance which we’ve embedded after the break.

We had considered not featuring this, since we looked in on the same home last year. But the number of tips that rolled in made us think that a lot of you missed it, or are just delighted by the multitude of blinky lights. Either way, it’s worth the four minutes out of your day– it will either put a smile on your face, or make you glad not to live across the street from this guy.

Halloween Hacks: Death Throws A Party

October 25, 2011 by 3 Comments

If you him the Grim Reaper, Azrail, Magere Hein, or simply, ‘Death,’ he sure throws a good party. [Victor] has an anatomical model of a skeleton at his job named [Hein], and for his birthday party, his coworkers decided to throw [Hein] a party.

[Victor]’s first skeleton-based build was last summer. The twinkle of the summer sun in [Hein]’s eye socket made for a great occasion to dress the skeleton up in some summer garb. [Hein] was dressed in a fashionable Hawaiian shirt and put in a window along a corridor. Of course, a skeleton is no good if there’s no element of surprise, so [Hein] held disposable camera that flashed every time someone walked by.

[Hein]’s birthday spectacular required something a bit more shocking. A blowout whistle was added to [Hein]’s mandible. With a PIR sensor and a TI Launchpad, [Hein] was commanded to blow the whistle every time someone walked by.

[Victor]’s builds may not have the shock value – or even be as scary as Halloween necessitates – but he’s got a few good ideas for what could become a great yard display. Check out the video after the break to see [Hein] greeting [Victor]’s coworkers.

Halloween Hacks: Transform That Annoying Dancing Santa Into A Halloween Mummy!

If you have one of those annoying dancing (Santa/Elvis/Frankenstein) decorations sitting around collecting dust, you could always repurpose it like [mischka] did. He originally wanted to enter our Santa-Pede challenge and purchased a dancing Santa, but time eventually got the best of him. With no other use for it in mind, he decided to make his dancing Christmas toy into a fun Halloween decoration.

An electronic rendition of “Jingle Bells” isn’t exactly the scariest thing around, so he dismantled the dancing toy and started fiddling with the sound board. A few well placed resistors later, his circuit-bent Santa Claus started to sound like he had five too many egg nogs, which was perfect for the dancing mummy [mischka] had in mind.

He transplanted some LEDs from Santa’s base into his head, and masked it off with some electrical tape so that only the eyes were visible. He then wrapped the mummy in the requisite bloodied bandages and set him out for the kids to enjoy.

Since it’s hard to find someone who genuinely likes these dancing toys, we think this is a great way to make them useful again. If you’ve got a few of these things kicking around, we suggest reenacting the dance routine from Thriller using an army of Santa-zombies and sending a video our way.

Halloween Hacks: A Haunted House Project For The Kids

October 15, 2011 by No comments

If the kids have been bugging you to get started with your Halloween decorating, [Dale] from BasicMicro has a neat and interactive project that’s sure to satiate their thirst for ghoulish fun.

His wife was looking for some new decorations for this Halloween, so he took a quick trip to the craft store and found a DIY foam Haunted House kit. After convincing her to do the assembly, he outfitted the display with some Starlite RGB modules, which have all sorts of interesting lighting modes built in. When the lights are turned low, the house jumps to life, as you can see in the video below.

The construction and wiring are not an overly complex job, so it’s a great starting point for little minds and hands that are beginning to develop an interest in electronics. For those kids with a little bit of experience under their belts, the house could easily be modified to use servos to create swinging doors and shaking grave stones.

The limit is truly defined only by their imagination (and your electronics budget), so why not give it a try this weekend? We’d love to see what you and your budding hackers put together!

Halloween Hacks: Building A Dark Ride In A Garage

October 12, 2011 by 15 Comments

Instead of the usual Jack-o-lanterns and creepy Halloween decorations, [Rick Murphy] built a dark ride in his garage a few years ago.

In case you’ve never been fortunate enough to see one in person, a dark ride is a track-based haunted house meant to be experienced on a small cart. Usually featuring sound, light, and animatronic displays, dark rides can be just as entertaining now as when you were eight years old.

[Rick]’s dark ride, “Scream in the Dark” was built in his 2-car garage over a few years. The kids that went though the ride were genuinely scared, but that made the kids in line even more curious – just the reaction [Rick] wanted.

The build is for the most part completely modular. The track is made up of 4-foot square panels that have either a straight track or 90 degree bend. The modular design means [Rick]’s garage doesn’t need to be a dark ride the entire year. The cart rides on this curved, raised track with the help of a few gear motors and 12 V battery pulled from a Power Wheels.

There’s a great gallery of the interior of the dark ride and a video after the break. If you’d like to build your own dark ride, check out dafe.org for a whole bunch of dark ride and fun house enthusiasts.

Announcing Our Next Theme: Halloween Hacks

October 11, 2011 by 5 Comments

It seems every year, Hack A Day is a little bit behind the times when it comes to Halloween hacks. Builds like the Mario costumes and the house singing Thriller are great, but it makes a lot more sense for us to post them before Halloween.

To introduce our Halloween theme, we’d like to present [heavyweighthowe]’s Halloween project. It’s a small lighting automation build that syncs a string of lights to the theme of the best Halloween Christmas 2nd best [Tim Burton] movie, The Nightmare Before Christmas. [heavyweighthowe] used Vixen to sequence the lights and an Arduino to interpret the serial commands from Vixen. It’s a nice build that would look great sitting on a porch next to a giant bowl of candy.

If you’ve got a Halloween build you’d like to show off, like a haunted house ride an awesome costume or even a really great Jack-O-Lantern, send it in on the tip line. We’re planning on putting up at least one Halloween post a day, so keep sending in those builds.

ATtiny Hacks: Robot Halloween Costume

September 24, 2011 by 7 Comments

When it comes to Halloween costumes, [Michael] doesn’t like buying expensive and poorly made bits of cloth and fabric that resembles [random Disney character]. Last year, his son decided to be a robot for Halloween and although gray spray paint and dryer vent hose make a very good costume, that only goes so far. The robot needed lights, so [Michael] spent a little time on this build that blinks a few LEDs in a random pattern.

The build is very simple; an ATtiny13 drives two 74HC595 shift registers. The code – all 30-odd lines of it – uses the random() function to shift high or low values to the shift registers. After pausing for a little bit, the cycle continues and a new patterns of LEDs light up.

The electronics of the robot costume could be easily transferred to another theme – astronauts need LEDs on their backpack, and of course aliens communicate with blinking lights. In any event, it would avoid last year’s fiasco with a dozen [Heath Ledger] Jokers. Check out the video of [Michael]’s intergalactic robot son after the break.
