My question has multiple parts. Is one allowed to set an alarm clock to ring on Shabbos? If the Alarm Clock has a small pod that vibrates, is that allowed? Is the vibrating pod allowed to be under the pillow on Shabbos? If the alarm is set to ring on shabbos, is one allowed to turn the volume down before it starts ringing? If the vibrating pod is set to go off, is one allowed to disconnect it from the alarm before it starts vibrating (there is no electricity going to the pod when it's not vibrating)?
