Yes, a static DIY iris is not too hard and actually improves ansi contrast figures.
However, a DIY dynamic iris is more doubtful unless you have electrical engineering experience, as it will require a method to measure and process on screen averaged output to correctly change the iris's setting, even more so the dynamic gamma needed to keep the gamma curve the same.
For a static iris you simply just need to place it just before the main lens assembly. It improves the ansi contrast as it prevents more scattered light from entering the main lens assembly and being focused with the rest of the projected image.

Maybe, but it would probably be more trouble than worth. Get a high contrast grey screen instead!

I have an HC1500 and was hoping to get better black level performance from it. Is it possible to add an iris to it for darker blacks?
