LIDAR System Isn’t Just A Rangefinder Anymore

For any project there’s typically a trade-off between quality and cost,as higher quality parts, more features, or any number of aspects of a project can drive its price up. It seems as though [iliasam] has managed to avoid this paradigm entirely with his project. His new LIDAR system knocks it …read more

xLIDAR Is A Merry-Go-Round Of Time-Of-Flight Sensors

[JRodrigo]’s xLIDAR project is one of those ideas that seemed so attractively workable that it went directly to a PCB prototype without doing much stopping along the way. The concept was to mount a trio of outward-facing VL53L0X distance sensors to a small PCB disk, and then turn that disk with a motor and belt while taking readings. As the sensors turn, their distance readings can be used to paint a picture of the immediate surroundings (at least within about 1 meter, which is the maximum range of the VL53L0X.)

The hardware is made to be accessible and has a …read more

Find Your Way with Tiny Laser Beams

For their final project in embedded microcontroller class, [Aaheli, Jun, and Naomi] turned their focus toward assistive technology and created an Electronic Travel Aid (ETA) for the visually impaired that uses haptic feedback to report the presence of obstacles.

We have seen a few of these types of devices in the past, and they almost always use ultrasonic sensors to gauge distance. Not so with this ETA; it uses six VL53L0X time-of-flight (ToF) sensors mounted at slightly different angles from each other, which provides a wide sensing map. It is capable of detecting objects in a one-meter-wide swath at a …read more
