I recently bought the toniebox to hack it for my son's 4th birthday. It has become his favorite object.
I considered building sometime custom, but the tonie hardware is cute, portable, and lovable in a way that would be hard to replicate.
It has been really fun for my wife and I to listen to our favorite music in the car, and then when my son says "I like this song" I "burn" him a little disk that evening.
He's turned into a little DJ, and has memorized a handful of his songs (and dances and sings along).
One caveat is that finding compatible NFC tags is a little bit complicated. if you buy from RFIDfriend [0] then they take a couple weeks to arrive from Germany.
Highly recommend!
Wow, if I can set up a usable process for my brother to do this for his kids I might get my uncle of the century award locked in.
