REVERSE ENGINEERING
This page shows the reverse engineering of the Oral-B Vitality electric toothbrush.
CALCULATIONS AND DETIALS
I reverse engineered an electric toothbrush and calculated various different values such as Torque and Motor Efficiency. To the left are the A5 cards that were present on my exhibitions stand. Click the links below for the high quality PDF and to listen to my 2 minute pitch.
CIRCUIT SCHEMATIC
To the left is a schematic of the electric toothbrush when it is plugged into its charging socket. Click the link below for the high quality PDF.
