Completed bicycle traffic signal cycling through traditional traffic light colors. This is the older, narrower version of the hood.
This is the first in a series of posts describing how to build a Wi-Fi enabled bicycle traffic signal. In this first part, we’ll go over the required parts, using a 3D printing and laser cutting service to build the needed mechanical components, and assembling the traffic signal. In the second and third posts, we’ll connect the bicycle traffic signal to a Particle Photon and Adafruit Feather M0 Wi-Fi respectively to enable the traffic signal to be controlled via Wi-Fi. In the final post, we’ll build our own control electronics, add a small base to house the new electronics, and expand the signal to three lights.
