Reviewing Project

A project log for Open LIDAR

This project is to build a motorized gimbal mount to convert a laser distance module into a 3d LIDAR.

When I left off the status was that I had accidentally back-volted my circuit and damaged every component (including the sensor).

I've been too busy with my Master program to tear apart the sensor to find and replace the burnt out components, but I now have a LidarLiteV3.

As I've been looking at the components that I burnt out, I'm realizing there are some improvements I can make. First, the Teensy 3.5 had a firmware update and now supports the LidarLite (and I presume the SF30). I've compiled the code for the Teensy and it compiles! This solves all my issues with not having enough memory to bulk-write to the SD card!!!

Another thing that I can fix while I'm at it is the motor whine. The motors were whining while using the knock-off motor drivers I had. Instead I can splurge for some $10 Pololu drivers that should work a lot nicer.

Also, there are now other people that have validated that the point cloud for these sensors looks awesome. Good enough for cave survey (but not for historical cateloging of archeological sites). So I'm also looking at my old plan to have this kit laser cut out of ABS. The devices I've seen so far were not stand-alone and had wires hanging everywhere to a computer.
