Wall mounted servo arm

thingiverse

I made this to hold a laser pointer and play with the cat. The code moves the laser around in random arcs and lines at random speeds to make sure the cat has a blast chasing it. If you decide to make this, message me for the code. And I recommend mounting it somewhere the cat cannot reach it because the servos do make sound when they move and cats really like to attack things that make sound and move. Don't make the same mistake I did... I modified the base to make it possible to mount the batteries and arduino alongside the servo arm. The rotating platform was modified to make it stronger and a little easier to print and the middle link was modified to hold a smaller servo. I also added a wall mount so the whole thing can be easily mounted and removed.
