ASHPD - DIY Lights & Sound Effects (for under $100)

So I got my Arduino and WaveShield last week (care of http://adafruit.com/), and I haven't slept much since ;)

This is literally my first project (I've never soldered anything before last Monday!). I thought I'd share incase there's other prop/replica geeks out there who feel the need to learn enough EE to make their own sound effects.

I don't think I've slept much this week....

Overview:
Aperture Science Handheld Portal Device (ASHPD) - DIY Sound Effects

Adapted from ebs' forum post to ladyada.net, here: http://www.ladyada.net/forums
And ladyada's dap.pde example: http://www.ladyada.net/media/wavshield/dap.pde

Hardware:

Arduino (pre-assembled) (Duemilanove) (http://adafruit.com/) = $30.00
Arduino-bootloader 2x upgrade chip (Atmega328) (http://adafruit.com/) = $7.50
Adafruit Wave Shield for Arduino Kit (v1.0) (http://adafruit.com/) = $22.00
SD/MMC Memory Card (1 Gig) ~$5.00
Sony SRS-A27 desktop personal speakers ~$17.00

Software:

Arduino 0013: http://arduino.cc/en/Main/Software
WaveShield lib: http://www.ladyada.net/make/waveshield/download.html
My Sketch source code (Arduine Code): http://downloads.rockyluck.com/files/PortalGun.pde

Functionality:
Power-Switch (SPST ON-OFF):

Turn the board (lights & sound) ON-OFF
On setup(): Plays the powerup_sound1.wav file and starts the ambient_loop.wav
ambient_loop.wav will continue to play while gun is on; and pauses when gun is fired or other effect is triggered

Mode-Toggle-Switch (SPDT ON-ON):

Changes between Orange/Blue lights
Toggles Fire-Button sound effects

Fire-Button (SPST):

Plays the color appropriate sound effect when pressed
[Optionally] Flashes 4 additional white LEDs
Follows up with randomly selected open-portal sound (open1 - open3.wav)

Invalid-Surface-Toggle (SPST):

Small discrete ON-OFF slide switch
When ON: causes the follow-up sound to play invalid_surface.wav rather than random open-portal sound

Superfluous-Music-Button (SPST):

When pressed it plays "Still Alive" by GLaDOS (Jonathan Coulton)
Bonus! If the Invalid-Surface-Toggle is ON it plays the "radio mix" edit of Still Alive

Now I'm off to bed... enjoy!
