OpenSimpleLidar

Open Hardware scanning laser rangefinder.
Its parameters:

  • 5 scans/second
  • 180 measurements per rotation (2 deg anglular resolution)
  • Maximum distance - 4 m
  • Measured accuracy ~3-5 cm at 3 m (depends upon the color of reflecting surface).

This device is really cheap - its components cost less than $30.
UPD from 2023: Cost of the image sensor TSL1401CL increased very mush, so total price can be higher!
See "TotalBOM" with price calculations.

Now I'm updating the documentation for this LIDAR.
Some of it I'm writing to the project wiki: https://github.com/iliasam/OpenSimpleLidar/wiki

Please take the simple survey about assembling instructions

This Lidar is using triangulation method for measuring distance to objects. It can be shown by this picture:

If you need LIDAR with increased speed and range, see this project: https://github.com/iliasam/OpenTOFLidar

Please leave your feedback if you will be able to build this Lidar - I need more feedback about assembing instructions.
