Julia’s Draft Instructable v. 1

Hello! Here is my very preliminary draft. I will update this to reflect some of the very helpful feedback I got.

LEAVE A MESSAGE AT THE GOOSE

Audio recorder and playback system in the shape of a goose

INSPIRATION

My partner and I operate on very different and constantly changing schedules. He is a first year resident in Internal Medicine; I am a design grad student. Although we live together, we can go days without seeing each other. We would like to leave each other notes, but video messages on the computer and hand-written notes aren’t working for us. This device is mounted at my door and is an easy way to record a brief message on my way out that he can playback when he gets home.

FUNCTIONALITY

Record audio
Playback audio
Clear audio recordings
Indicate new message with LEDs

PARTS

Electronic parts:
Arduino Uno
Adafruit Wave Shield for Arduino Kit – v1.1
Electret Microphone Amplifier – MAX4466 with Adjustable Gain
AC Adaptor
Arcade buttons
LEDs
Wires
Resistors

Housing:
MDF
Glue
Screws
Paint

ASSEMBLY

 Step 1: Put the parts together

Follow Wave Shield assembly instructions here
Mount the microphone and speakers (more TK)
Create a circuit for the LEDs and push buttons

Step 2: Write the code

Load the WaveRP Library
Write code to link the functions for recording and playing back to button functionality
Write code to create connection between message status and LEDs

Step 3: Build housing

Cut out the GOOSE PANEL (or your choice of image) from MDF using the scroll saw (or laser cut if you are doing something complex)
Create shallow box to attach to the back
Sand and finish with paint*

* The housing can certainly be made of many materials—I just used MDF for this example because it is easy to work with and generally accessible

Step 4: Putting it all together

Mount the board to the back of the goose in the box
Thread the button and LED elements into the front of the goose in the designated places
PLUG IN!
