I was recently rummaging about in my parts bin and i cam across this thingy:
This used to be part of a toy i had as a kid, which was a spinning top that would start to play music and flash lights when it was spun.
What i'm interested in mainly is the metal thingy at the bottom of the picture. It's just a thin piece of metal (copper?) with a weight mounted at its tip. when the base is subjected to a horizontal movement, the metal strip vibrates and creates contact with the metal flanges it rests between. This in turn triggers a circuit.
I was thinking of ways of how i could include this as an enhancement to the 'start here' robot. Maybe have it sense when it hits an object, or make switch off everything until it is gently 'dropped' on the floor?
