Outcast's Rest: Enchanted Prison Box Containing the Evil Spirit Named Putreghast!

The Outcast’s Rest is an enchanted locker created by benevolent spirits to entomb the foul Putreghast. For ages, the locker stood silent, but as time marched on… something changed. The locker now calls out to you when you are near, the entity within begging for release. The voices claim that it is John Callaghan, American tourist that is trapped within… however can you be sure?

The project itself is centered around the ornate decor and the voice lines, it is all made possible with the Adafruit Sound FX board and a PIR sensor that triggers the board to play sounds whenever you are near the box.

Special thanks to Tony DiCola for his "Halloween Scream Box" for setting the groundwork for the hardware.

For the Electronics:

– Audio FX sound board WAV/OGG Trigger with 2MB Flash

– Small Powered External Speaker

– PIR Sensor

– NPN Transistor

– Male-Male Jumper Wires

– 3x AAA Batteries and Battery Pack

– Soldering Tools

– x2 Solderless Bread Boards (that fit in your box)

– Micro-usb cable

For Decor:

– Embossing Foil

– Embossing Stylus

– Flat Back Cabochons

– A Wooden Box

– Double Sided Tape

Make sure to connect your components as such:

Luckily, this step is quite easy. Use the micro-usb cable to connect the sound board to your computer. The sound board should appear as a USB device where you can store your sound files on. It only accepts .WAV or .OGG files encoded in a specific way. For this project we are using .WAV files. You must make sure your .WAV files are formatted at 16 bits and sampled at 22050 HZ or less. Free programs such as Audacity can allow you to do downsampling. After your audio files are recorded and formatted, you must name them correctly in order for them to play. We are going to use the Random play feature of the sound board, therefore we have to name the files in this fashion: TN__RAND_.wav 

TN should be followed by the trigger PIN number we are using, for us, we are using pin 05. Rand should be followed by a number to name the sounds we are using (0-10). Therefore the final file names should look like this: TN05RAND0.wav, TN05RAND1.wav, TN05RAND2.wav, etc. 

Now all you have to do is drag and drop these files into the Sound Board and it should be good to go! The hardware handles everything, no coding, isn’t that neat?

Now comes the real fun part, using a foil of your choice, use embossing styluses to create decorative designs and imprints upon the metal. Cutting them into fittings of your choice and adhering them to the box with double sided tape! You can free hand it or create designs on paper, it is really up to you! Be creative! 

Connect your charged speaker to the Sound FX board and connect your circuit to power. Stand the breadboard with the PIR sensor on its side so that the PIR sensor is up against one of the walls of the box. Make a mark of where the PIR sensor makes contact with the box and also make a mark where the breadboard stands.

After all your marks are made, drill a 1 cm wide hole into the area of the mark, this will allow the PIR sensor to see outside as well as let some sound escape.

After drilling, use double sided tape to tape down the bread board so that it can stably stay on its side. Power up everything and close up the box, it should now play your sound files whenever there is motion on the side of the box where the PIR sensor rests.
