Inspiration

People in wheelchairs sometimes need to ride in the road. They need a three foot safety zone between their wheelchair and passing cars.

What it does

Uses a motorized rotating light bar on a foam pole to provide a safety zone of three feet between their wheelchair and the passing cars.

How I built it

Cut wood for backing. Mounted light bar into foam pole. Attached motor to the backing board, and then the foam safety pole to the motor shaft. Programmed the Arduino for the light bar, and the motor rotation control. Mounted the laser line module to the backing board. Mounted the battery pack to the mounting board.

Challenges I ran into

Could not find the correct geared rotation motor with the supplied rotating disk that securely attaches to the shaft. (In my house.)

Accomplishments that I'm proud of

People think it is a great idea for wheelchairs, bicycles, tractor trailers, buses, motorcycles, etc. that need a safety zone to allow cars to see them better, and/or a way to block traffic when turning or riding.

What I learned

Learned more about what persons in wheelchairs need, what is practical, and changes needed for production of products.

What's next for Three Feet Led and Laser Lights Safety Bar.

More prototyping, production and sales for the bicycles, tractor trailers, buses, motorcycles, etc. market to help fund the product for the wheelchair market.
