Sure, you can buy a musical greeting card for someone special, but wouldn’t you rather buy a musical greeting card for someone special and rip it apart first!
Making a wooden musical greeting card
The process is pretty simple. First, buy a musical greeting card and rip it open to get to its guts.
There are two components: a microcontroller and a tiny speaker. These are help in place with mounting tape or a small dab of glue. A sliding plastic strip makes and breaks the electrical contact, turning the music on and off.
I glued thin strips around the edges of 3mm plywood. I really wanted this greeting card to be as lightweight as possible. Plywood is your best bet for ensuring the two halves are flat and close together properly. If you use solid wood, you will likely have to fight warping. That’s packing tape on my fingers: I can’t stand getting super glue on them!
I cut a tiny slit into one of the frame pieces for the plastic slider to run.
I made the pull-tab a bit more substantial by sandwiching it between two pieces of thin wood: edge banding. Then I attached the two musical components to the wood using carpet tape.
I drilled a circle of holes in a plywood panel to improve the sound quality, and glued this into place.
The front cover is two pieces of plywood glued together. This keeps it flat and provides extra thickness for attaching hinges.
Iron-on edge banding conceals the plywood edges and makes the wood appear solid.
I printed out some colorful images and transferred them to all faces. (Learn more…)
