BILL OF MATERIALS:

Insert:
    Prewired Digital Audio Recorder from Radioshack
    photoresistor(s)
    1K ohm resistor(s)
    9 volt battery
    8 ohm speaker (or small 16 ohm)
    Fabric/thread
    Velcro/button for access to battery

Outer element:
    Fabric
    Cloth-ribbon or elastic (1.5 " thick)
    Velcro
    Conductive fabric
    Wire wrap
    Wire
    LED
    220 ohm resistor
    Arduino Diecimilia (or Arduino mini + usb adapter)
    Sharp IR Sensor

OTHER CONSIDERATIONS:

On/Off switches
        -not necessary for outer element because sound only occurs
for 20 seconds. Will not continuously play unless it is exposed to light.

Speaker
         -at 16 ohms but is too large to fit in most vitamin bottles. Need to look into replacing it with a smaller speaker — is an 8 ohm speaker going to be a problem? Should I find a smaller 16 ohm?

Size of insert:
        -Must be able to fit in the hole of the vitamin bottle and not be too tall as to make it difficult to take a vitamin. If it is too bulky or too long I need to consider making a special bottle that has this insert integrated. Or perhaps a giant pill organizer.

Size of outer element:
        -Arduino important for such a small function…hooking up an IR sensor to an LED? Arduino mini would probably be ideal…but I already have a normal size Arduino.

Shape of outer element:
        -Should it take the form of a vitamin? Should it just be like a pillow? It will be made of fabric.
   
Battery access:
        -Must be easy to access the battery for both elements.
