Hi all.
Have just been looking into using mobile phone vibrate (pancake) motors as haptic feedback sensors.
The basic plan is to have each motor driven by a discrete micro (possibly 10F200) that is programed to respond to only one frequency or pulse width, sharing common data and power lines with micro also set up to stop the motor very quickly by driving its power line to ground via resistors.
The micro is mounted on the back or side of the motor for a compact shape with only three wires required.
These are generated using a spare unused 5.1 ch output from PC audio or other channel (Bluetooth headset?!) and are set up to pulse any one motor or a selection of motors, the exact coding will also determine the on time.
Additional uses for this could be to provide a low frequency audio feedback for cheap headphones for those "thumping bass" fanatics, simple to do and requires a single PIC12F675 to interpret the audio stream and generate pulse widths (therefore motor speeds) as required.
