    This is a very cool project.
    But I don't get why you use 3d printed parts in so many places, they are fragile and not water tight.
    Laser cut aluminum sheets brazed or plexiglass sheets welded together would be water tight.

    I believe I have answered most of these questions up above. I don't need them to be water-tight save for one area and I have already coated those. 24 hours and not a drop lost. As far as being fragile, non of these parts are load bearing and I have already stressed tested my prints. Laser cut aluminum or plexi is not at my disposal. For me to get anything custom made, I would have to spend time designing anyway. Then I would have to send off to get the parts cut/fabbed. I would be at bey to whomever I had making my materials. This is something I can design, send to the printer and and install in at my pace, 24/7 in the comfort of my own home. Sure, I could get my own laser cutter but I don't have the space for one and if I bring one more piece of equipment home, my other half will have something to say about it! It took some doing to get her calmed down about the 3D printer!

    Unfortunately, a job change has put this project on hold but when things in my life normalize, I will get this going again.

    So I have finally gotten back to working on this project. There is still much to do and if I am to get it completed for Halloween this year, there is not much time to do it. I have gotten all the fabrication done. Most of the main assembly is done. All I have left to do is get the fan assemblies attached and get all the electronics hooked up. The sides of the fogscreen are wood for now, only because the aluminum pieces I ordered are not ready yet. I need to get it working for Halloween so, wood will have to do for now.

    Just like with lasers, I hate fabrication. Assembly isn't too bad but fabrication is the worst. Especially metal work. Anyway, here are some photos of what I have completed, thus far. Please excuse the mess of my workshop. It was a small back-house bungalow, turned into storage, turned into my workshop so, it's got a bunch of junk in it!

    A short post with not a lot of info but mainly pictures... I have been too busy to get any more info posted. I'll keep posting progress here though. I hope to have this working (temporarily) by Thursday or Friday. We'll see how that goes!

    Straws for the fog delivery chamber. I wish they were black but oh well. No one will see them inside.

    Thank you! It's been a fun and very frustrating build!


    First "light". Very quick and dirty setup to test and see if the damn thing works!

    This is the first project that I have ever built that was completely designed in Sketchup and built off the dimensions in the 3d model. I have to admit, I was a bit nervous cutting and modifying materials based on a model in the computer! Almost all of my dimensions were derived from the model. I suppose next time I build something, I won't be as apprehensive to design on the computer and then create it.

    Some more pics...

    That video was fun to watch, Absolom. So you are just planning to shoot fog up or down, not recapture it with a vacuum set-up and recycle?

    I've wanted to set up a fog screen in my space for years now covering a 10 foot wide by 8 foot high area, but I have the project work its way to the top of my TO-DO list. So many project, so little time . . .

    This will only be shooting down. This one is designed a lot differently than my old one. It must be overhead and level to operate correctly. For me, the idea is so that people may pass though the screen. It is used more as an "interactive" display and less of a screen specifically for display.

    A few more pics and a brief video. I will get more posted once I have time. Too much to do before Halloween!

    The fog stays very laminar and stable, all the way to the ground. It doesn't get wavy like my old one.

    Very concise, 1/2" sheet of fog!

    98% finished!

    And now, a projection. I'll get a video uploaded soon with the Halloween projection video

    **EDIT: That's what I get for posting with my Mac. It always turns the pics sideways. When I get on my PC, I will repost them.

    That seems to work pretty well. in the first video it seemed to only come from one row of tubes. Is that correct? If so, what are the other rows for?
    What do you use as a fog source? What is the duty cycle?
