Recycling cameras

Yes, my next door neighbor who recycles stuff would be very happy to get her hands on my old, broken cameras, as well as the local Senao, but I am thinking, maybe I can do something more useful with them. If anyone has any suggestions, please do tell. I have a Panasonic FZ 20 and a Canon Powershot S80 that are broken beyond repair -literally. Pity the lenses.

Senao will probably get the Samsung… as soon as I finish breaking it. Anyone has a sledgehammer?
