Open Source scanning laser rangefinder

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

Utility for displaying "radar" scans from the working Lidar:

Example of Hector SLAM working with this Lidar:

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

Some modeled pictures of the assembled Lidar can be found here: https://github.com/iliasam/OpenSimpleLidar/tree/master/Misc/Pictures/

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.

opensimplelidar's Issues

Where to get Lidar?

This isn't exactly an issue, but I was curious from where to buy this lidar module. I coudn't find any single place where lidar is being sold at this price.
It would be great if you can help with using hardware modules.

CPL file?

Sorry, noob question. Not sure what I should give for a CPL file when ordering through jlcpcb:

Gerbers are not source

Currently the PCB files are provided in gerber file format which are only used as input for manufacturing. These are generated output, not actual reasonably easy to modify original source files. If I want to go round off some corners (for example) it's really not worth the sheer amount of effort that would be needed to modify them.

Native Eagle, Altium, KiCad, etc. files would be much easier to access. Until that happens, I wouldn't be exactly referring to this as "open".

TSL1401CL Linear Sensor Obsolete

https://www.mouser.com/ProductDetail/ams-OSRAM/TSL1401CL?qs=5Gq2pvdsSAxzAfrSHNCmXw%3D%3D

Found on Aliexpress here:

But it's $20.

Is there a more modern and available part that is compatible?
