You and your instrucatbles friends just published the best instructable on the face of this planet. What better way to celebrate than to whip out your new PARTY BUTTON!!!!!
P.S. I apoligize in advance for some of these pictures, as my camera has no flash
Step 1: Materials and Supplies
1) A mint container (round and plastic)
2) An old dome-switch keyboard
3) An old singing birthday card
2) A soldering iron
Step 2: Prepairing the Key/Button
Take out the metal backing and the screws on the inside. Remove the dome-switches (in image two, it's the clear-ish thing on the mint case). Set this aside. Next remove the keys and the backing to them. Take a key of your choice, and pry it off with a screwdriver. BE SURE NOT TO LOSE THE ROD ON THE BACK!!!
Replace the rod into its original possition on the back of the key.
Take the dome-switches and cut one dome, and some area around it, off.
Glue the rod/key onto the dome switch (see image three)
Step 3: Prepare the Card
This part is a little hard to explain, so if you have any questions just ask.
Take the small plastic objec, and place it inbetween the metal switch and the metal plate on teh board. You need to put it far enough in that the music isn't playing, but you can depress the metal switch and start the music. When you lift your finger off, the sound should stop as well.
Step 4: Prepare the Conatainer
See how there are two flaps?
Open the smaller one and cut it off with the exacto-knife. Then fire up the soldering iron.
Once the soldering iron is hot, melt the plastic away until it is roughly the size of a key.
Step 5: Put It All Together
Place the speaker inside the caseing as well.
Place the top of the case back on so that the hole is directly over the key.
Let all the glue dry and your ready to party.
Step 6: Bonus!
Also, you can speed up the music on the board and speaker. Simply look for a small area with "R1" written above it. While the music is playing, place your finger on the area. The music should speed up. If you remove your finger, the music goes to normal.
