My Bachelor boxes

salesm21
salesm21 over 8 years ago

To any who can help,

I have a project in mind and was hoping someone could help me get it off the ground with some helpful insight. I am getting married in 2019 and I want to send out these boxes to the groomsmen as a way to say "hey your a groomsmen". The thing is I want to incorporate a bit of electrical circuitry into the boxes. My idea is that when the box opens up a song of my choosing will play. Now from what research I have done I have found that I want in general is a switch, SPST N/O, to activate the song when the box is opened. I want a DC power source but not sure on the specs it will be required to have. Next I was looking into speakers and it looks like Thin speakers are the way to go instead of piezo buzzers because I was more than just one tone. This brings me to my next issue, storage. I wish to have a song play when the box opens but I don't know how to store that info in the circuit so the speakers knows what to play. The box is 10in wide by 10 3/4 long and the song is about 2 min long. Any help with this project would be greatly appreciated.

    So I noticed in your list you have a external USB Portable Battery back up. Why not just use a 9V Battery or something like that?

    The module has a USB power input connector so it is easy to plug in a USB battery, but you will need to control the power with your switch.

    The module does not require any other circuitry or micro, but it does need a microSD card to store the MP3 audio file.

    Hi Mitchell,

     

    You should be looking for something like this,

    https://bigdawgsgreetings.com/product/bare-usb-light-200-sec/

    a little tweak with the circuitry should do what you need, you can also find little cheap option from aliexpress.

    Cheers,

    Sakthi

    You probably don't want this advice but I'll give it anyway:

     

    1) get married in 2018 (early in 2018)

    2) put all that love and effort into making your wife happy and looking after the kids

     

    My only regrets after 26 years of marriage are the time I wasted on unimportant things.
