Electronics science fair project:
Controlling Food Intake Speed with Electronic Circuitry

Project Information
Title: Controlling Food Intake Speed with Electronic Circuitry
Subject: Electronics
Subcategory: Electronic Devices / Medical Instruments
Grade level: High School - Grades 10-12
Academic Level: Ordinary
Project Type: Experimental
Cost: Low
Awards: 1st Place, Canada Wide Virtual Science Fair ($250)
Affiliation: Canada Wide Virtual Science Fair
Year: 2013
Materials: 555 Timer, resistors, NAND logic gate, LED
Description: This tool measures eating speeds by counting the userís mouthfuls per minute (M.P.M). If the userís M.P.M exceeds the recommended eating speed of approximately 3 mouthfuls per minute, an LED will flash until the user returns the fork to an upright position. A monostable 555 timer circuit counts a seventeen second long signal each time the fork is used. If during this time an internal tilt switch changed position, a logic gate combines these two outputs to produce another signal transmitted to the LED lights, causing them to flicker.
