We all do it. Despite the fact that we might be destroying some fragile major award under the Christmas tree, we like to shake our wrapped gifts to try and figure out their contents. Well, here’s a geeky prank you can play on your loved ones the next time they go to shake their presents.
Instructables contributor DIYHacksAndHowTos came up with this simple circuit which you can install into a box, and it’ll play back any sound you want when the box is shaken.
The circuit requires just a small number of inexpensive components you should be able to pick up at a Radio Shack (or order from their website), and minimal soldering skills. Once assembled, you record the sound you want it to play, hot glue it to the box, and let the fun begin.
Nice sound there at the end. Though I like the idea of recording Chewbacca’s growl or maybe some broken glass if I make one.
This seems like a simple enough gag that someone over at ThinkGeek should consider turning it into a product for next Christmas. For now, you’ll hae to build your own. You can find complete build instructions over at Instructables.
