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.

Making progress slowly. Last night I was ready to try a first room scan...but I picked up the unit with the USB still connected. The arduino was pulled out of the female header socket and when I set the tripod back down the pins shorted and burned out the arduino (battery power was still on). Didn't have time to check whether any other parts were damaged. New arduino arrives Thursday.

I'm also getting strange results when I convert my spherical RAE file to Cartesian XYZ. My scan only had two pitch scans all the way around and azimuth varies 0.225 degrees. But converted to XYZ the angle appears much larger. Also, the pitch results appear to be repetitive. I suspect I may have an algorithm problem with the pitch calculation, and I may have a sin/cos decimal error with very small angles. Will try to work on the processing sketch more tonight.

[Edit: ...and...my angles are in degrees but sin is in radians...that explains that.]
