Introduction: Noisy Package
This package, designed to hold a poinsettia or plant, makes squeaky scratchy noises. The air holes and "This Side Up" labels encourage the recipients to think something else is in the box.
I used an mp3 player for sound reproduction/amplification.
A battery holder (3 AAA) provides power for the circuit. Positive goes to pin 1, negative to pin 7. Pin 7 is tied to pin 12--this causes the player to play and repeat the sound recorded on the mini sd card. The file placed on the sd card should be labeled 01.wav.
I used this speaker.
The speaker is connected to pins 6 and 8.
Using 3 mm screws, I attached the speaker to the 3d printed mounting holder. This is not a perfect fit, but I supplied the files anyway. The sound is quite loud and the speaker could be duct taped to the box and everything would work fine.
On/off is controlled by putting the batteries in/out (we're not talking high sophistication here).
To keep the plant and circuitry from crashing around into one another, I made a cardboard stand to hold the plant and the sound equipment. Duct tape is my mounting material.
Inside the box, it looks like this before the plant is added.
Run time is 8 to 10 hours, so it will work fine if you need to take a gag gift to a party.
Maybe you could change the labels to say "Live, This Side Up." No fibbing involved.
