Howdy !
I did not get a lot of time to work this week, but I did find a way to attach the visible light filter (aka floppy disk) to the camera, by hot gluing it to a circle in soft plastic that I cut earlier. It works pretty well, and my next step will be to (finally) build the prototype ! As a starter, Mr. H and I decided to make it on a piece of cardboard, so we can easily move it around and not annoy anyone by taking wall space.
However, I did end up losing the piece I attached the filter to, so I had to make bigger, stronger one and glue it to the camera so it wouldn't move. I also ended up building the actual prototype and marking with tape locations on the table to calibrate the laser, and it works pretty well ! I still have to find the best way to calibrate it, and I am looking forward to attach the entire thing to a wall, to kind of stick it in place.
