Open Hardware scanning laser rangefinder based on Time-of-Flight principle. No standalone laser rangefinder modules were used in this LIDAR, so its schematic and firmware are fully open.

Its parameters:

  • Scanning speed: scans / second
  • Resolution: ~ 1% of distance, but not better than ± 2 cm
  • Minimal distance: 5 cm
  • Maximal distance: ~ 90 m (white surface)
  • Angular resolution: 0.5 deg
  • Measurements frequency: ~ 25 kHz
  • Scanning angular range: ~ 600 deg, could be increased by changing mechanics
  • Power: 0.1 A at 5V (0.5 W). Start current could be bigger than 0.8 A.
  • Size: 114 x 114 x 600 mm

Price of the components of this LIDAR is ~ $ (without delivery).

See BOM with all calculations: “TotalBOM.xlsx”.
This LIDAR is using COTS (Commercial Off-The-Shelf) optical components – standard lenses for surveillance cameras.

There is a big article in Russian about this project: https://habr.com/ru/post/ / Google translation: https://translate.google.com/translate?hl=en&sl=auto&tl=en&u=https://habr.com/ru % 2Fpost% 2F % 2F

That is how its components are assembled:
