The LTP Lidar was a simple 2D lidar I hacked together based on the LidarLiteV3 back in 2017 when the cheapest half decent 2D rig you could get was 5 grand.

I used a [[pic24f|PIC24F]] to interface with it and built a custom actuated PID
controlled head with slip ring and encoder. If looking for a Lidar unit nowadays
there are cheaper 3D units nowadays.
