I'm intrigued by safe openings, but would have actually liked some explanations of the process. Also...you can film horizontally if you're not making a < 1 minute shorts video. Have a nice day! =)
The laser is for when the wheels are super evenly matched. The laser lets me shoot the contact points over a longer distance to amplify the readings. I don't go too much into the laser explanation because it's really difficult to figure out if the readings are meaningful. There also the issue where experience tell me right away if I'm shooting too far or too close. Alot of time will be wasted if it's not setup properly. If you see my video of safe #13, you'll see how the laser is set up with a measuring device. I had to move it several times before I started getting proper readings
