McDonalds Kids Meal Avatar Toy Taken Apart

We have all seen the McDonalds Kids Meal Toys, they usually last about a day and a half before they find their way into the trash. David Cook from the Robot Room decided to take an Avatar McDonalds Toys apart to see what made it tick. Turns out there isn’t much for electronics since it uses an ASIC to get the work done. One neat feature is that the piezo element is used as a sound device and a vibration sensor. The board is also well documented, I was actually surprised to see any silk screen! Interesting design but I am disappointed that this thing is made to be disposable, there are a stack of batteries inside that were not meant to ever be changed.
