I've got one of those singing Santa toys where you squeeze his hand and he sings jingle bells for about 30 seconds and turns off. Unfortunately he stopped singing all the sudden so I decided to make a small project out of him.
He's powered by two double aa batteries inside his belly. Inside I found a small circuit that was wired to a switch in his hand. The circuit has a speaker, two transistors, what appears to be a capacitor, and some sort of memory chip where I assume the song is stored.
I looked around and everything appears to be connected nice and solid. I know the circuit is working because there's a red light in his nose that lights up when you squeeze his hand. Right now when I squeeze his hand the light glows red for a while (what appears to be the duration the song was) but no music
I soldered the speaker to some old headphones to confirm it's integrity and it works fine. Any ideas as to troubleshooting from here? I've read online you can use a circuit from a singing greeting card but I'm not sure how the push button normally closed switch in his hands would be able to trigger the song to play all the way through and shut once the song is over :/
