I'm working on a project where a laser beam has to be steered by me, not a laser show software.
The scan speed requirements are very low, as it takes input eye tracker data and moves a laser beam where a person is looking.
...basically it allows people to pop balloons by just staring at them.
Servo motors work but they make annoying noise from their gears and arent very accurate.
Since cheapo slow scanners are so cheap, why not just use them I thought. After all laser beams are what they are meant for.
Okay, so first question.
1) Is 0v the minimum tuned angle of the scanner in a given axis and 5v the max angle, or is the signal more complicated than that? For controlling I'm going to be using an Arduino taking input from a PC which in turn takes input from a webcam eye tracker camera.
2) Since the speed is so slow, is there a chance to bypass the need of large amps?
3) Since the speed is so slow, is there a chance to use 12V DC to run it rather than 24? I already use 12 for everything else so would be nice to not add an extra PSU to the box.
