Engineering Innovation – a new way to use LED Drivers

A project log for 3D Haptic Vest for Visually Impaired and Gamers

This project's goal was to make a vest that a visually impaired or gamer could use when moving around in their environment(real or virtual).

The vest uses LED Drivers to control 48 vibration motors. I researched and couldn't find a good solution so I originally used shift registers to do the pulse width modulation. But then I thought of LED drivers and they worked much better. Coincidentally both of them have similar properties.

I will publish the code soon.
