Inspiration

There is a void in the market of affordable sensing devices for blind people, so our project seeks to fill that void and provide blind people with a product that can potentially make navigation safer and easier for them.

What it does

Uses ultrasonic sensors to help blind people navigate their surroundings

How I built it

Using a trapper's hat, some cardboard, eight ultrasonic sensors, and a raspberry pi, we built a headset held together with duct tape, hot glue, and solder.

Challenges I ran into

We originally wanted to use solder to connect all the sensors and ic chips using solder, however we ran into issues with sensor misfires, and faulty solder joints, so we instead moved to using a breadboard and hot gluing all the components in place.

Accomplishments that I'm proud of

The thing works. It just works. All eight sensors read range and run correctly, and that is an absolute win.

What I learned

We learned a lot about soldering and controlling i/o ports on a raspberry pi. Soldering fell through, but we still believe that we have become better at it, and hope that we may be able to use soldering in the future.

What's next for Sight Headset (v2)

The plan is to add more sensors to the design, and 3D print a frame for the headset so that it can be presentable as an actual product.
