Raspberry Pi

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).

I wanted to use the Raspberry Pi in this project because it is a miniature computer that could replace the big laptop I use to control the vest. Originally, because I wanted to make another box, I made a Python program to control Adafruit 12 PWM port LED Drivers but Python on the Raspberry Pi is too slow to run them. So for my second attempt to make the Raspberry Pi (that I purchased from Element14) control the vest I sent the startup and controller commands to the Parallax Propeller and let it do the hard work to control the Adafruit 24 PWM LED drivers in the original box.

Currently my Raspberry Pi can control the vest and pretty soon I will have code written for it for gaming. I have also 3d-printed a case for the Pi to prevent me from frying it when I handled it.
