Hey guys.
Friend's birthday is coming up, and her & I have a little inside joke going on; she's a unicorn.
Long story short, I wanna make her a unicorn horn, that lights up.
Here's the hard part.
I want it to either:
Light up when it detects sound (so it has to integrate a mic)
or, plug it into an iPod, and it flashes with the sound of the sound; but a small speaker must also be inside the horn.
And remember, it has to be wearable.. for a girl!
So I just don't know what speaker I'd be able to use, and what batteries I'd substitute in...
Or where I can even find a freaking unicorn horn.
It's just a fun concept, and if it turns out to be ridiculous, then I'll probably scrap it.
Here's something I came upon, which kinda gave me the idea..
