This is awesome! How long did it take you to make it and how much did it cost?

I want to see how Sean Merritt set up his door ghost with the ultrasonic humidifier.

I liked the teaser video, but would like to see the setup!

Steve, any updates to your fog screen or did you abandon the project?

I’ve been looking into doing the same thing on a much smaller scale (a steampunk desktop monitor using a pico-projector and a small ultrasonic mister). If you want to make nice laminar air, check out the info sections at Exair. They make laminar flow air knives:

I got it to work with an ultrasonic humidifier!! This project ended up setting me back quite a bit, but it works! Looking forward to sorting out a few small problems for next year.

My link to the video made your spam blog block me! It is on youtube under seanwmerritt

Brian, I’ve seen these for $30 at Bed Bath and Beyond… And they produce a lot of nice vapor. Ruling out some factors, (The Fog, The fog juice, and the trash can) You can probably create some nifty effects with water. You may need two. We’re waiting to hear from you steve!

You can get ultrasonic nebulizers (sort of) if you purchase a ‘cold vapor’ vaporizer. They use the same basic mechanism. I’ve also seen them at shops that sell backyard pond supplies.

i would love to make one of these… i’ve been looking online for information, and yours is the only one i’ve found!! good job on this!

I am planning to begin this journey of building one, but if there is any way of communicating with you for tips and ideas, i would greatly appreciate it!

hey ya all

i was thinking what would happens if you replace the fog machines with a 2 piezoelectric devices that conformes the medical use nebulizers? , those things work with a high frecuence piezoelectric which crash the water by ultrasound, making h2o particles realy tiny, producing fog. As i know thats the way original fogscreen works right? it could be a little expensive but you can try asking medical companies for parts .

Has anyone considered a bank of small 1″ 12v fans across the bottom to pull the smoke through in a more linear fashion?

or possibly a recirculation system to re-use smoke once it’s properly mixed with the air, to virtually eliminate the billowing smoke effect, and make more of a holographic look?

Love the project man, really got me thinking….

It seems as though I’m the only person on the Internet who has thought of this but,

you can make your system much more compact, continuous, and over all effective if you replace your fog machine and bulky fog cooler with a simple bucket of dry ice and water. It may seem a bit low tech but it works a heck of a lot better. The gas naturaly sinks and the effect lasts a lot longer.

this is a great job for a DIY project, well done!

I second the anon post above re: making use of the reynold’s number approach, that is the same method which is utilized for rough-draft designing and sizing of wind-tunnels, it can prove suitable to helping guide future revisions of this project.

I keep staring at this. I feel like I am in the Gadget Louvre. I wonder if it could be adapted to make a cold smoker for my cheese? Must chill woodsmoke or it melts cheese.

Awesome. I tried building one for Halloween this year too but ran out of time. Please keep us posted with updates. I will to at http://www.thehauntedshack.com

Right you are! I have edited the copy to read ” As anyone who has ridden the latest iteration of…”

“One small nit – the fog effect in the Pirates ride at Disneyland is a fairly recent addition, so to say that anyone who has “ever ridden” the ride knows the effect is not really the case.” plus, the effect is not right before the first drop, it is right before the pirate ship harbor scene, so I guess that is two nits… Ed

Just saw the video at the top of the page. I feel like an idiot. But it looks great.

Would love to see video of this in action. It’s a really cool project.

Thanks Goat!

But I’m no genius, just stubborn – err, persistent.
