Laser Turret
Description
I love playing with my cat, but sometimes I also love to lay on the couch and not move a finger. So I made a robot that controls a laser pointer, that she can hunt and follow. With these three pieces you can control the orientation of a small laser pointer. It gives support to two 28BYJ-48 stepper motor, and a laser diode with a cylindrical case 6,5mm wide, like https://www.ebay.co.uk/itm/6mm-5V-Red-Laser-Dot-Diode-Copper-Head-650nm-For-Arduino-Raspberry-PI/263354370619?hash=item3d5124ca3b:m:mDu8i5E2VYlOvw92IJ70sEw . This mount puts the two motors so that the barycenter is at the axis center of the bottom, or "longitude" motor. The middle joiner is probably a bit thin but it works for me. There are no stop elements. Maybe a future version will add them.
