Hello All, My latest project. A functioning 'LIDAR' unit. Well, it's not actually a laser, but rather an IR unit. I used a TFMini IR distance sensor and converted some C++ code for an ultrasonic sensor to now work with the TFMini. Ultrasound sensor only ranged to ~30cm. My IR scanner goes out to 14m (there is available a nice true laser distance sensor but too big for my project). I wrote a whole bunch of code to command sound, and some cool display effects. You can check out a room in the dark. Pretty cool stuff.
I used a teensy 3.2 (great little processor!!), adafruit 2w amp, adafruit FXmini with 8 recording channels, adafruit 1.8TFT, and a few other electronic bits. Designed and 3D printed the case freeCAD and Cura. Project almost complete.
I guess one could adapt this concept to an automatic RC collision avoidance or docking system.....hmmmmm....
