Here's what's new with the bear project as of yesterday:
Roller switch installed in the chest. Giving it six hits restores normal heart rhythm in the bear.
New "convulse" routine. The bear convulses until CPR is performed.
Improved chest action. Two metal plates sandwich the servo, make a much more realistic breathing response. Extra stuffing and the rumbler for the heart sit on top.
Accelerometer wired up and coded to check for the proper positioning of the bear, i.e. the bear must be laying down before CPR can be performed effectively
Work has begun on the sounds, both the simple ones for the bear and the richer ones on the Processing interface.
Work has also begun on the Processing "heart monitor" application.
