I’ve been keen to find an excuse to learn how to work with motors.
I think I’ve finally come up with a simple project that’s still inspiring enough that I’ll actually finish it.
I want two mirrors motorized mirrors to redirect a “laser” around a corner.
Some kind of low power (class 1) laser or LED spotlight.
I’m thinking one Mirror will have panning control and the other tilting control.
The challenges I think I will face are.
- weight.
- precision.
I’m happy to 3d print some flat surfaces and put some reflective tape on them to keep the weight down. Obviously real mirrors would be preferable.
I’m also after as smooth of a rotation so I can direct the laser.
I also need moderate speeds. Something like 5-10 rotations per second.
I don’t need full 360 rotation, somewhere between 45 degrees and 180 degrees will be plenty.
In-fact, I like the idea of the motor being restricted to certain angles for safety.
Even though I want to work with safe red lasers I still don’t want the risk of a bug in my code throwing lasers randomly around the room.
here is a quick sketch.
I’m currently imaging these support beams coming out of the back of the mirror that will be attached to either the servo horn or even just the servo gear itself. I’m open to superior suggestions.
Have I found the right motor for the job?
Have I bit off more than I can chew?
Thanks in advance
