Hi everyone,
Im after some advice and help...
My name Danny and I am currently a final year Product Design student at University of Brighton. For my final year project Im looking into a solution to help prevent/reduce accidents at festivals, towards festival goers. In the poorly lit sections around the festival.
I came up with using a laser suspended 12ft up in the trees or suitable platform, to project a grid pattern onto the ground below. In order to highlight potential obstacles. Similar to....
Lumigrids: Do you think cyclists are stupid? | thatsflawesome.com
But ofc better than this as its just full of so many flaws!
Anyway, I've been currently using two cheap eBay laser pen that come with pattern caps, one of which can produce a series of lines so by having two I could produce a grid like pattern for a prototype.

No I know the theory works I want to make a fully working final prototype using one laser to project a grid pattern. So this were you guys come in I have limited knowledge on laser so sorry for all questions...
Ok so the laser itself needs to eye safe and in red, I know you can get specific eye safe lasers but from the company I spoke to they wanted £200 so wasn't within my budget just for a model, So wondering which rating and what sort of laser would be safe to use and suitable for being on for long periods of time?
Its going to be a self contained unit that houses the laser and I assume some sort of transformer? so that it can runs from the mains supply at a festival?
Now for the grid pattern itself I have been looking into diffraction grids etc and ordered these:
Howie Glatter Holographic Attachment for Laser Collimator - Square Grid Pattern | eBay
GRID lens for AixiZ 12X30mm laser modules | eBay
but wondering if anyone else has an ideas on anything I could use to produce the same effect.
Any help appreciated
Danny
