This instructable walks you through the steps of creating and installing a unit that will play any audio for up to 20 seconds when a toilet is flushed.  The audio is easily recorded onto the unit using a built in microphone. 

Here is a video of the finished product:

Step 3: Solder New Play Button

Solder the flat button to the "play" 3ft long wires.

(Use the button you just cut off in the previous step or use your additional button if you skipped the last step)



Step 4: Solder New Record Button

(If your additional button is flat and you did not cut off the record button you can skip this step)

Solder your additional button to the "record" button wires.  You might want to use your copper wire to extend how far the button can reach.

**At this point you are done with the electronic components.  Your circuit should look like the second picture. 

Step 5: Mount Speaker

Trace your speaker on the outside of the project box.

Cut out a hole along your mark using an Exacto knife.

Glue the speaker into the hole in the project box. (The box will actually amplify the sound)
