Default Re: hidden radio ideas or just slighty out of sight. wood hide door?

I used an arduino micro, a tiny MP3 for arduino, 2 MOSFETS for an amp and some small speakers from a TV. Mine run from a single 18650 cell but you can use other power sources. (don't use 5 volt for the MP3, it dies, 4.5 is better)
Hidden speakers. A few hidden buttons on a remote for the controller (built in volume has 30 volume level settings).

The bass could be better, but it's remarkably good for it's size.
If you want i can post the code, but i haven't finished the navigation code yet.

Remote hidden under the seat most of the time. It's on that short cord in the picture so i can pull it out when i want & hide it when i don't.
Alternatively you could put a bluetooth expansion board on it, it'd still fit on a credit card, & connect it to a fancy phone if you wanted to, i've never coded that but children can so....
