hello there! can you give me some advice I currently have a second hand prolight controller linked to a basic 1.5w laser soon im upgrading to the HarpeLaser controller but im a bit unsure what watt to buy....would a 3w be too weak...a 10w too powerful? i want something thats sensible yet room to expand into

@ThereminHero 5 жыл бұрын

First use more haze. I have never had a problem with my 2.5W being clearly visible in medium size venues so long as there is plenty haze. For large venues I usually ask for an appropriate laser to be provided since large venues usually have a laser person available.

Is there anything I should know regarding laser safety? Given that the lasers used with laser harps typically are Class 4, they are not only dangerous for the eyes, but could even be a fire hazard and burn the skin. This kind of has me second guessing whether I should get a laser harp or not.

@morphman86 7 жыл бұрын

Here I assumed it worked by a reflector sensor at the bottom measuring the strength of the reflected laser beam. Does this mean you won't get any reading other than "not has been hit"? If you measured the strength, you could get more variations, much like with a theremin.

@ThereminHero 7 жыл бұрын

+morphman86 lasers don't loose enough strength over such short distances to measure

@morphman86 7 жыл бұрын

Having used quite a lot of laser measuring instruments over the years, I can tell you that yes, they do. They loose enough strength that you can read the strength of it when it's aimed at a window, convert to audio and listen to what people inside are saying. If it can measure the vibration of a window, which is like 1/10th of a micrometre, I'm fairly certain you can measure a halfing of it's beam with at least some accuracy :)

@ThereminHero 7 жыл бұрын

You are right that these instruments are able to do that, but my understanding is that the beam is formed in a more precisely measurable way. With these "laser show" lasers, it is more difficult because the source has not been calibrated for measuring distance. I could be wrong though!

@morphman86 7 жыл бұрын

It's harder, yes, but still possible. The method you showed here is probably half the price or less (and I'm guessing that's still not cheap). The method is pretty much the same, but instead of a light sensor, it would be a reflective sensor (which is a lot more expensive). You still measure the time it was hit to find the note, but with that you can also measure the distance to the hand. Another route to go would be to have two light sensors at a known distance apart and write a controller program that triangulates where the beam hits. It would save a lot of money, but can be trickier to program and requires a very precise measurement (down to at least 5mm) every time you set it up.
