This is a project I did the other week called Sound Effects Suit Jacket:
Inspired by sitcoms and cartoons.
I thought it would be fun to be able to add sound effects to my own life. So I made a sound effects suit jacket.
The sound samples are triggered by a control panel with 4 buttons (3 for samples, 1 for changing sound banks). And then being played from an Arduino + Wave Shield through a portable speaker. All the hardware is kept within the inner jacket pockets while in use.
Inception Button
The weekend before last, at the urging of some colleagues at North Point, I decided to make a real-life version of the Inception button. (If you haven't heard of this website, you should visit the link and give it a push. :) It basically makes the same intensely epic sound popularized by the movie Inception.)
In order to give the Inception button a physical existence, I, once again, turned to Arduino. The next logical step after that was to use Adafruit's Wave Shield. It really was pretty simple to build once I figured out what needed to be done.
I used Sparkfun's big red dome button and housed everything in an enclosure I bought at Fry's.
Here are the inner workings of the button. I drilled a hole in the top of the enclosure for the button to fit through and wired the button to the Wave Shield, which sits on top of the Arduino. The Inception sound is stored on the SD card, which fits into the slot built on the Wave Shield. Super convenient. Audio is coming from an 8th to 8th" cable out of the Wave Shield.
I had originally planned to have it be battery powered, but after realizing that it probably needed to have a long life, I ended up powering it with a DC adapter.
The final product:
And here is the button in its new home at the North Point Media offices!
Drew up a schematic real quick today.
I might end up changing it, but it's really pretty damn simple.
Essentially, I'm just connecting the FSR's (Force Sensitive Resistors) into the Arduino so that I can have sounds actuate when the Force Sensors are touched.
The supplies I bought finally came in the mail. The supplies are:
Battery Powered Guitar Pedal - For playing the instrument along with your iPod etc.
Breadboard
Arduino Uno
Arduino Wave Shield - For storing sound samples
5 Force-Sensitive Resistors - For acting as the Buttons Attached to the Steering Wheel
Steering Wheel Cover (The giant scrunchie looking thing)
Tomorrow I'll be posting sketches and schematics! I'm excited to pump this project out.
Done With Instrument #2
The first prototype for the Car Steering Wheel Drum Machine is done! I probably won't be able to properly film it until Wednesday though.
I've decided that this is a project I'm going to refine over the summer, so there will be lots more to come.
Gotta say, I'm pretty excited about it.
Last nights progress. I got the basics of the drum machine all together. Today I am wiring up potentiometers and trying to get them to effect the sounds and switch the sound banks.
To say getting the Wave Shield running was a struggle is a bit of an understatement. I ran into a bunch of problems along the way, but I finally got it up and running. The wave shield plugs into the top of the Arduino and allows me to store memory on an SD card so I don't have to plug into the computer to access files. In this test I just have two buttons mapped to sounds. The rest of the buttons, are for later. In addition, I'm using a 9 volt battery as a power source. The sounds are just place holders for what I'll use in my actual project.
Over the weekend, I'm going to really dive into the programming, and build a small little frame for this so I can attach it to steering wheels.
