Hi,
Happy new stuff to you all...
After examining my car during the week I've found a few new paint chips in the doors, and strange tyre marks on the back bumper.
I'd really like to forgive the people who did this - obviously there was a mad rush to return faulty Xmas gifts and some people felt the need to kick open their doors to expedite a quicker run to the claims department... To quote from someone 'God forgives...'.. Well just now I'd like to find these fine people and nail their out-of-control limbs to something appropriate :-)
Anyway, this led me to thinking of a bump sensor, and although there was a circuit published in SC

I was thinking of a circuit that would use a purpose-built IC to amplify a piezoelectric sensor and interface the output to a microcontroller which would take the appropriate action ie. trigger an alarm, camera, fire a harpoon etc...
Anyone seen anything like this around or know where I should start looking?
Cheers, Phil.
