Introduction: Hack That Musical Greeting Card! (Headphone Edition)
Created by the Think, Plan Create Clan as a part of our instructables sponsorship guide.
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Materials
You will need...
* A musical greeting card
* A headphone port (I got mine from a mini FM radio from the dollar store)
* Thin stranded wire
* Wire strippers
* A Hot Glue Gun (With Glue)
Step 2: Dissecting the Card
Cut open the card so you can see the circuit board and speaker as shown above. Cut the speaker's wires about halfway between the speaker and the birthday card, and remove the speaker with the help of the scissors (It may be glued down pretty well!). Save the speaker for future projects such as www.instructables.com/id/The-Altoids-Tin-iPod-SpeakerCase/.
Step 3: Assembling the Headphone Port
Hot Glue the headphone port to the bottom of the card. The reason it is placed here is so when the the card is put back together, you can easily access the headphone port. Attatch the wires from the circuit to the small prongs on the headphone port as shown in the picture. Secure your connections with hot glue. You may want to hot glue down the wires to the card so they don't get in the way while you're opening and closing the card. This will also prevent the wires from tearing.
Step 4: Testing
Plug in your earbuds and test if it works. If it doesn't, go back through the steps and try it again. Your problem may be a few loose connections or maybe a few wires came undone, so you are going to want to smother all new connections with hot glue and even electrical tape if you have it. If it does work, hot glue the card back the way it was so it looks like a typical greeting card, and you're finished!
Step 5: Enjoy!
I hope you enjoyed hacking your musical greeting card, and say goodbye to those noisy, annoying speaker cards that seem to be set on and off by themselves! Questions and comments are appreciated! Enjoy!
