Sheet product dispenser with auxiliary feed button

This is an automatic dispenser for sheet products like paper towels, using a motor and a controller to dispense a length of paper. It includes an indicator light to show its status. A special feature is an auxiliary button that can dispense paper even if the usual paper-sensing mechanism isn't working correctly.

Why it matters: Since 2011, the cost and reliability of embedded microcontrollers and sensors have improved significantly. This makes the electronic control and override logic more economical to implement in mass-produced dispensers today.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateMotor, controller, sensors, software logic, custom housing
