How to make a mp3 car horn? Answered
I have only seen one consumer product on the market and it retails about $200.
I'm not up for spending that much for what seems like such a simple goal.
Is there some kind of MP3 chipset/micro-controller with a USB input where you can load a .mp3 onto a flash drive (or onboard memory) and then wire it up to a speaker/horn?
This all seems really simple in writing but is this something one could actually do?
