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.

Oozby lets you design with OpenSCAD using Ruby

OpenSCAD is pretty popular amongst the 3D Printering community.  You can design your 3D modles using a meta language that describes what you are trying to build.  Frustrated with some of the methodoligies that OpenSCAD implements, Bluebie created Oozby.

While I can’t say that I’m much of a Ruby person, I’d much rather prefer using Python variants like SolidPython or pySCAD I can appreciate the goal to make technology more accessible to other people with different backgrounds.

Check out more on the Oozby site, and the source code on Github.

The Happy Birthday Box

Everyone usually agrees that home made gifts are usually more heart felt.  So instead of buying a gift,  Christian decided to make one for a friend.  Not too far from a musical birthday card, the Birthday Box, will present a message to the receiver on an LCD screen, and sing the song happy birthday.

The Happy Birthday Box uses a piezo buzzer for a speaker generated by an Arduino.  The text message is displayed on a standard 16×2 LCD screen, and powered by a battery pack.  There is a small roller switch as well, I assume everything turns on / off when you open and close the box but it wasn’t specifically stated as the functionality.

Keep this project bookmarked, and add a few LEDs for that valentine of yours.

Check out a quick video after the break;  Source code and more pictures on Christian’s blog.

SPiBot r/c tank uses Raspberry Pi for recon surveillance

SPiBot is a remote control platform with tank-like tracks.  It’s a work in progress, but will be fitted with a rotatable camera, microphone, and distance sensors.  It is to be controlled via the web on either a phone, tablet, or laptop.

The base for the platform is a Raspberry Pi.  WiFi is used for communication.  The HTML interface is served up using nginx and PHP.  Motor control happens via PWM from the Pi to motor drivers.   Video and pictures will be done with some combination of raspivid, vlc, ffmpeg, and raspivid.

It looks like the project is pretty far a long, but not quite finished.  Hopefully the author has some pets he can terrorize when it’s finished.

Source code on GitHub, and the original project link here.  It’s not in English so here’s the google translate link.  Video of the control test after the break.

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.

Biometric security toy box is awesome

bombox2Taking a ploy from the upcoming TouchID feature the new iPhone will have, Grant was inspired to make this really neat toy box for his son’s toy car collection.

You would think getting a fingerprint reader would be the most difficult part, but apparently Adafruit has ‘em for sale!  So Grant got a fingerprint reader, a hobby servo, pushbutton, and some batteries and hooked it up to an Arduino UNO.

Looks like a fun project, especially for something like a jewelry box.

Check out the source code and other details on Grant’s site.

Check out the video after the break.

HardDJ Arduino based MIDI controller uses hard drives as jog wheels

Stumbled on this awesome project that uses 2 old hard drives platters as rotary encoders / jog wheels.  Obviously for the purpose of DJing!  I love it when people reuse hardware that was originally intended for another purpose.

The build uses an Arduino Mega 2560 as its main processor.  RGB LED’s for the VUmeters, some slider pots for fading, and some extra buttons and knobs for MIDI events.  On the PC software side, the author is using mixxx for the MIDI mapping.

 

Check out the video after the break.  More pictures in the gallery.  Source code here on GitHub. More documentation here.
