First off: I would like to thank everyone for their support, comments, and votes! This has been an amazing experience and I'm so glad all of my trials and tribulations can help new people make their own displays :D

I've always have been into pushing my haunt to the next level each year (3-axis animatronic skulls I designed, home-made rgb led dmx lighting, the hearse, singing busts, projections, etc), and this project was no exception. It is by far my favorite creation and several hundred people stood in front of the yard for hours watching the effect.

After going to Disneyland, and seeing the new addition of Davy Jones and Black Beard to Pirates of the Caribbean the ride, I knew I would have to make my own! :D

Upon further research though.... the information on these is non-existent, as they sell for well over 100k new... which is wayyyyyyyyy out of my budget (and I'm guessing your's if you're on here reading this too!) so I set to work...

If you would like to see the commercial version that I am replicating... Click Here...

Goal- to make an 8ft wide fog projection screen for a penny on the dollar (1k or less - wait wait wait dont look away). What I achieved was an 8ft fog screen, at around $250-300... so that's 3/10's of a cent on the dollar as they say.... sound interesting?

Now I have to apologize at the forefront for the terrible video and low light shots, as all photos were just taken on my camera phone... and thats why I really hope I can win the contest so I can finally get great shots of all of my efforts!

Below are two tests of the unit, and honestly it is very quiet other than the sound of the fogger (thats all you hear in the video).

So if this peaks your interest... read on... and I will do my best to guide you to making your own! Happy Haunting!

And if you enjoy this please vote and check out my other halloween themed instructables. :D

Lastly, this project utilizes power tools, soldering irons, and electricity. Please exercise caution and always wear the proper safety gear! Pleaseeeee......

Hi Jayepmills, those server ventilation panels are interesting, I've never seen them before. You could use something like that if you'd like, with a fewer number of fans, and it might work alright but honestly the gaps between fans will be visible in the final image. It sounds like perfect image quality is not the primary concern though so this may work out great for you and save a decent amount of build time. The fewer fans you run though, the higher speed you will need to run them at and therefore higher noise. Where you can cut down fans though is in the central portion of the screen. On performance night I actually didn't even use the low voltage central fans as my 12v power supply was being used for my led lighting and the image was 80-90% as good so you could just get away with the two outside banks of fans honestly as long as it is blowing upwards. I am designing a tabletop model and I have another concept for a simplified version as well that if I don't take then into production I will gladly place them on here as instructables. I hope this helps. If you have any questions feel free to ask and I will try my best to answer them ASAP (I am in my final semester as a design student so I'm being pulled every which way lol).

I am toying around with the idea of fog screen projection in a live theater project later this year. Your work is inspiring. Question about the fans. Is there any alternative to wiring up 80 of those bad boys that you think would result in a good image? What I would be projecting would be even better if it was obscured a little by a slightly less perfect fog screen. I am going for shadows projected on fog. If what I posted below could be found cheaper, what are your thoughts? Or even using just a few desk fans? Thanks in advance!

Yes it can definitely be sized down. A member of my haunting group built a 4 foot version for his indoor haunt after seeing mine and it turned out great. He even used a tiny led projector for it since the walk through was extremely dark. :D

This is incredible! Do you think it would be possible to do this same project in a smaller size, say 6ft or 4ft? Thanks!

Dang it I can't watch the videos on my iPhone! Could you let me know the youtube name to search for? I tried several combos and your name here and it didn't look like these vids? I voted for you anyway cause you a mad about halloween! Me too bit I could not wire a lamp much less these! And I live where it is hot and I would have to do something with smoke. I tried the chillers am all and it was a no go

Yes it definitely could be inverted if you would like. For me, blowing vertically allowed for the unit to be placed behind a low wall and seem invisible relative to the rest of the yard, vs having a roughly 2ftx2ftx8ft display hanging (and having to build supports/use a ladder to fill the fog machine). Having it on the ground, also allows the projected image to go into the sky vs going onto the floor in front of the unit (as the video is a rear projection). It really depends on your situation. Great suggestion! Thanks!

Could the whole setup be inverted so the fog blows down? Then people could walk underneath it and through the projected images. This would solve the issues with people potentially walking over it and damaging the aluminum honeycomb.

Files up and viewable on Step 2 :D in .c4d, .obj, .dxf, and .3ds formats
thedudedrummer (author) 4 months ago
Thank you very much! And update: I had to rma the radiator because of a leak so the replacement should be here by tomorrow afternoon and I should have the file up right after that. Again my apologies on the delay.

Excellent! What a really cool project.
thedudedrummer (author) 4 months ago
I will try to pull an all-nighter on it tonight so it can be up here by tomorrow night. I'm switching to watercooling so I need to run the loop for 24hrs before I power up the machine -to check for leaks-
thedudedrummer (author) 4 months ago
Hi BrittLiv, I will gladly do so. My computer is apart this week for some repairs but the second it is together I will have them up on here and email you a set directly. Thank you for your interest. Also please let me know if .obj or etc would be a preferable format.

Hi, you are talking about "template from the .c4d file", but I can't seem to find it. Any chance, that you can re upload it?

The video loops I used were mostly from videoblocks.com I believe. Some was stock footage I have from my work as a content creator as well. Videoblocks usually has a free trial that allows you to download a limited number of videos a day for two weeks, so it is a great way to source footage on a makers budget. Hope this helps!

This is great, where did you get the video you used?

As to the transparency issue, you can achieve a much more transparent image with a lower wattage fog machine. When I tested it with a 400w we couldn't see the fog at all at night, but this also resulted in a much dimmer image (and as this was our centerpiece for the haunt we wanted it as bright as possible - with as wide of a viewing angle as possible). But the water vapor has a lower operating cost than a fog machine because of the fluid and power costs (long term). But this design, even with the fans only running at half power was still able to project a great image with ~5mph wind. Thank you again for the amazing compliment! I put my heart and soul into this thing.

Thank you very much tdhg and Davidandora! If you'd like to watch the videos on YouTube they're under my other YouTube account of Renderhof. Or my photobucket at Riddomike.

This is spectacular! I've rented one of the professional units for an event. No kidding about the expense of it! Your version with a traditional fog machine is perfect, especially for your outdoor use. The water vapor screen on the unit I used is more transparent, but super sensitive to drafts, wind, etc and for all it's expense would not look as good as yours does in your setting. Great Instructable- Thank you!

Thank you very much for the compliment. I actually know the exact ultrasonic misters they use, but those even from china would be 800-1000 plus the additional need to a water pump, filtering sponge to keep the larger drops from escaping, a water level sensor, plus having to ensure everything is water-tight. So my design made some compromises to stay on a haunters budget but I am very pleased with the results. I just wish I had better photos and video of the final product, but the test videos still do a great job of showing the overall effect. Thank you again and best of luck in your fogscreen building ventures. :D

this is exactly what ive been looking for for about a month form looking at the pictures of the "official" fog screen and reading what online info i could about it (because like you said there isn't much info in the technology used) i surmised a pretty similar set up the only thing i was thinking different was the use of ultra sonic atomizers which are also really cheap, but your results are phenomenal either way

Wow,what an amazing setup. I always wanted to try this. You should have a feature jump through the fog timed with something onscreen, like throw a dummy through during a fight scene.
thedudedrummer (author)  Renard_Bleu7 months ago
Yeah, I was thinking about this too :D or make people walk though it ... but I was afraid the aluminum honeycomb would get damaged and I have no way to replace that cheaply. With a few design tweaks though its definitely possible! Thanks for the great idea!!
