Now that I think of it, I've done lots of projects with lasers. And as a matter of fact, I'm working on another project with lasers, right now! I'll shoot some videos soon, so stay tuned. And till then, have fun building a laser tracking camera!
I've finally finished creating Part 2 of my article on controlling stepper motors with a computer. This time I have built a laser tracking camera panner by extending Andrew Kirillov's motion detection code (with permission) to control the motor.
