lol, this :rock:
I made something just like it when I was in high school....I didn't think of its potential as anywhere near this. aside from me being a bookworm, I have a tendency to "improvise" "headache machines"
site of enlightenment: photo class darkroom
Whenever we would start loading film or washing through the chemicals the professor would engage the force air ventilation system
I found that when blowing at a piece of paper weighed down on a table make a very distinct flapping sound, so I simply threaded paper strips in a salvaged rectangular container and left it in an open air duct, whenever the ventilation kicks in the room sounded like someone just dumped in a nest of bees in...being the dark means the scene gets very chaotic.....the enlargers are on one wall, the chemicals are on the other wall...theres two walkways...and 16 people at once. I admit I regret doing so, but the invention essentially saved my grade when I couldn't get a good print but has no real method of postponing the due date
