The first prototype is almost fully assembled! Shown here is the ultrasonic sensor mounted in the temporary (prototype) casing with LEDs wrapped around the edge, lighting up as objects get closer to the radar sensor. This will be mounted to the seat-post of the bicycle facing backward, with an additional unit mounted to the handlebars for initial testing.
In the video, we're using an Arduino board (temporarily) while working on getting a Teensy board set up properly for the ultrasonic radar sensor. The goal right now is to have it ready on Friday before the long weekend so I can take Velalert out for its first test drive!
