• Requesting help making an MP3 based music box
    9 replies, posted
I want to make a neat little gift for my girlfriend this Christmas. She loves music boxes and Final Fantasy, so I figured I'd see if I can make one to play the "To Zanarkand" music box mp3 I have. The only issue is I have no experience with any kind of crafting other than the limited experience from shitty school projects. I need guidance, if there is an easy way to do it I'm all ears, but if something involves circuit work and whatnot, I might be able to get a friend to help. Does anyone have any idea where I should start? Googling didn't offer an effective solution.
just rig up a speaker to an lm386 amp and hook up a cheap $5 mp3 player to the amps input
How would I have it play when the box is opened?
find an mp3 player that starts playing as soon as you turn it on and rig up a switch for the power button I guess.

You would need a pressure switch, too, one that initiates when released. Rip one out of an old dryer or something, because those only turn off when the door's closed.
I was thinking just a regular normally-on momentary switch sitting somewhere in the box, with a hole drilled above it and a little rod glued to the lid pressing it down until you open it
Can always use a simple light sensor. Its gonna be pitch black in the box so when its opened it should start going.
I could probably figure out how to do the switch and mp3 player thing. Any idea where I could get my hands on one of the mp3 players that start when they're turned on and an actual switch?
the light sensor is a better idea actually, they're just a variable resistor with a photovoltaic sensor on top. the way you should be doing it it would function like an spst switch [editline]9th November 2011[/editline] [url]http://en.wikipedia.org/wiki/Photoresistor[/url] this is essentially what you would need
