    Hey guys do you know those greeting cards that when you open them they play a tune or something? What Im looking to do is get one of those sound units and make it play a sound of my choosing when a box is opened.

    Anyone have any idea where to even start?

    Some of those build a bear places have things that let you record a sound onto them.

    Or you can use an attiny85 to play audio directly from an sd card to a speaker, I've done that before

    UM66 is a 3 pin transistor type IC sound generator. Only plays what it feels like though..
