Adafruit has released instructions for building a haptic headband—a wearable that uses vibration patterns to provide silent notifications. The project features a motor controller capable of creating distinct haptic patterns like taps, clicks, and hums that users can recognize and distinguish. Designers can integrate the electronics into a bandana or headband, making it particularly useful for meditation timers that signal you without audible alarms. Beyond meditation, the programmable vibration patterns open possibilities for accessibility applications and other notification-based uses.
