I do have to say that this vibration sensor gizmo is really really
It's sort of one of those, "Wow I never seen something like that
before!" type of thing.

I just got back from Earl's.

We could not get the AT90S1200 to work. It comes from the factory set to

use an external crystal, and will not allow you to change to the
RC osc. unless you program it with a high voltage programmer.

For some reason after using a crystal we could still not program it.  We

could ID it, erase it, but it failed on programming.

Finally we gave up and used a AT90S2313 and it worked.

We were able to test the LED's the vibration sensor, and the Sound

I have a interesting vibration sensor.

You can get it from Digikey.  It is not quite sensitive enough  But we
a piece of masking tape on it to lengthen it and it became sensitive 
enough.  We used a comparator in the AVR.  Because of the sensitivity,
ended up comparing it to ground.  It is a little piezo device which
like a capacitor. As it flexes it generates a positive voltage in one 
direction and a negative voltage in the other  Fortunately a flex in the

positive direction is enough to detect.
