Velo Viz is a bike-mounted LED system designed to enhance visibility and safety. It combines dynamic lighting with proximity sensors to provide real-time feedback for cars when passing.
I’ve experienced firsthand the challenges of bike safety, especially the risk of collisions with cars. This system is built for those who want increased security and visibility during nighttime rides.
Velo Viz is more than a product; it's a community-driven safety solution. With our detailed, cost-effective open-source documentation, anyone can customize and build their own system tailored to individual needs.
Iteration 1
Tested the first iteration on cycling friends and got great ideas for the 2nd prototype
Based on the feedback, what did you learn?
- Since some tests were done indoors, they were unsure what the device was for
What worked, what didn’t work?
- Followed the instructions well, knew how to power the device on
- Confused by power source and switch
- Not being mounted to anything and not having indoor props made usability difficult give feedback
How will you incorporate the feedback into your next steps with your Capstone?
- Still need to test device outdoors and on a bike
- Use 9V battery instead of power bank
- Place LEDs in spokes, and on clothing -> areas with movement
- Use of bluetooth so I don’t have to have wires in spokes
Mounting LEDs and lighting to parts of the bike that already moving
This additional movement will add more visibility: Cranks, pedals, wheels
Bluetooth LEDs on a wrist/leg band for more visibility
Additional functionality -> so pants don’t get caught in chain
Iteration 2
Fully functional LED patterns connected to Arduino Uno R3
Additional spoke mounted LEDs for more visibility on side profile. The extra movement makes the cyclist even more visible, more likely to be seen by a car at an intersection.
Iteration 3
