We've made good progress on the ranging LIDAR prototype over the last week and here's a video of it installed on a modified Companion Bike Seat. The LIDAR sensor is sitting on a servo to expand the range of "visibility" of the sensor by scanning back and forth. It's not incredibly clear from the video (LEDs and video don't play well together); this bicycle radar prototype is delivering information back to the LED board from eight discrete positions. Each vertical line on the LED board represents one of those sensor positions. The distance an object is from the LIDAR sensor is displayed by the number of LEDs lit in that vertical line. The closer the object is, the more LEDs light up. The LED board for this functional prototype is set up such that it creates a two-dimensional display of what is going on in view of the sensor, based on those eight discrete positions.
I'm bringing my bike down to Radicand tomorrow afternoon to have them install this latest prototype of Velalert onto it. If all goes planned, I'll be testing out this latest proof-of-concept bicycle radar next weekend!
