Hey, guys - I'm an electronics enthusiast, and for my next project I've decided I want to tackle a laser harp. I've started working with some glycerine for fog to get the beams to show up, and I could kinda/barely see a little red laser pointer (build into a $3 toy, so I'm guessing ~5mW, if that) with the fog I used, but I'm looking at possible an RGB laser for the actual harp so I can control the color a lot more precisely. I'm hoping for the final build to be <$100, which is quite ambitious, I know - but my questions is what sort of wattage it takes to get a laser to show up in fog, and how much color plays a role in that? I will possibly have a TV on in the room - if I can, I want to make a "laser harp hero" game - so I know that's gunna make a big difference. What are your thoughts on these lasers - that is, how will actual power output compare to advertised, and how well will it show up? Not going for super long-distance accuracy here.
