There’s still time for these Halloween hacks!

Halloween isn’t over yet, there is still time to make something cool for Halloween.  Here’s a few to inspire you.

First up is Halloween Prank.  While not a completed project, this is a good base for Arduino powered scare tactics!  The build uses an Arduino, an Ultrasonic distance sensor, and a servo.  By detecting ‘someone coming to your door’ possibly, the servo is triggered.  In Jacob’s build the plan is to drop a bunch of spiders on people walking up.  That sounds like fun.  You could also make it actuate something to jump out at your unsuspecting victims.

Source code for Halloween Prank is available here on GitHub.  There are more pictures and a test video on Jacob’s site.

Great idea — turn uav/drones into flying ghosts!

Looking for something fun to do this Halloween?  How about scaring the crap out of people everywhere.  Alton Porter has a pretty good setup for this.  It looks like adding a lightweight skull (either wire-frame or Styrofoam), some LED eyes, and some tattered cloth.  Just make sure you don’t interfere with the blades, nobody wants you to crash your quad!

This would be amazingly cool with a swarm of small drones.  Great idea.

Animatronic Rats do the spooky dance – Ratsberri Pi

Found this one while looking around for more Halloween inspired hacks.  Hari picked up a bunch of rubber rats at the dollar store and decided to make a Halloween project out of it.

A Raspberry Pi connected to a Pi Cobbler breakout board, and a 16 channel i2c PWM servo controller puppet an array of rubber rats.  Everything is powered by a pair of hobby LiPo batteries and 5v regulators.   The rats eyes were swapped out for some bright red LED’s giving a pretty authentic haunted house look.

There’s still time to put something like this together before Halloween!

A Disney inspired Haunted Mansion portrait using Rapsberry Pi

If you’ve ever been to the Haunted Mansion at one of the Disney Parks, you remember lots of small spooky stuff going on.  One of the things they like to do in the Haunted Mansion is have these portraits that slowly change from regular people into ghouls and ghasts.   Brandon decided to craft one up himself.

Powering the portrait is a Raspberry Pi, with a 19″ LCD.  The whole thing is wrapped in a decorative IKEA frame, painted with a little patina to look antique.  On the face Brandon is using Gila Platinum Window film which makes the glass into a 2 way mirror.  Software wise it’s using a Raspberry Pi Video Looper.  And here is a link to the video loop of Master Gracy on YouTube, but you could probably make your own if you wanted to.

Check out Brandon’s web site for more details, and here is a PDF containing a BOM and a few more details.

Check out the video after the break;  Kind of creepy.

Spooky Halloween effects door using Raspberry Pi

Who doesn’t love Halloween?  Especially since most of us are on the other end now doing the scaring instead of being a scared kid snatching up candy.  Cabe wanted to create some pro haunted effects for himself and came up with a pretty cool project.

The build uses a 24″ LCD screen that is supposed to look like a window.  Behind the door are a bunch of solenoid’s controlling pneumatic piston’s that really bring the video to life, making you think something is on the other side trying to get out.  Everything is controlled by a Raspberry Pi, and it is triggered by a photoelectric beam sensor.  The code is written in good ol’ regular c and the video is played through OMXPlayer.

Check out the video demo after the break.  Source code, schematics, BOM and other details can be found on element14.

Wirelessly controlled flaming Halloween pumpkin uses an Arduino

Halloween is a great time for makers, we get to make all kinds of cool costumes and spooky things.  Sometimes we get to play with fire.  Well at least Chris Lee does.  This flaming pumpkin is enough to keep them pesky kids from toilet-papering your house, or catching it on fire after they do.

The pumpkin is triggered by an Android phone, talking to a RFU-328 radio and Arduino.  The Arduino triggers 2 relays, 1 to activate a furnace igniter, the other activates a solenoid that releases the flow of gas.   The spray mechanism comes from an AirWick room spray and is filled with butane.

Chris made a comment about maybe converting this to shoot silly string out during actual Halloween, either way it’s a cool project.
