Maybe you have a sick Furby which doesn't act properly.
Maybe you have a dead Furby. How you got it is not important.
Maybe you want to see how Furby works.
Maybe you want to make Furby into a animatronic puppet.
The goal of this project is to strip Furby down and remove his brain, leaving his other functions intact.
Personally, I intend to stick another microcontroller in there.
What you choose to make Furby do is your business!
I used two different Furby toys for this demo.
Doesn't this one kind of look like Katy Perry?
Step 1: Split Furby's seams
Furby's skin is mainly held on with a zip-tie around the base of his body.
First, expose this zip-tie by cutting the single string that ties the cloth around the head of the zip-tie. I recommend a seam-ripper, but a pair of scissors or a scalpel (!) will do.
Now you can see the head of the zip-tie. Unless you can figure out how to undo a zip-tie, you must cut through this sucker. I recommend wire cutters.
Furby's skin pulls off like a sock, or like someone's shirt, until you get to his face.
