Is it to do with the amount of air that can pass through it?

That’s sort of what I thought, but good to know. Cheers.

Excellent point. It’s quite a small drum too, which probably means it’s much worse for the environment!

either air pressure or a photodiode with an IR led shining through the filter (that’s how it was solved on a projector I had)
