DIY fogscreen display for all human beings.

Similar projects worth following
Here's my DIY fogscreen display. The cost to build this is relatively inexpensive (excluding the pico projector because I pre-owned it, in USD the total cost was $110) and easy to build. I use corrugated plastic for the housing coz it's cheap and easy to bend into shape. The app displayed is my solar system guide video game made using Unity.
  • 1 × PC power supply I just use a small pin to power up the power supply. Google for more info on how to power the PC power supply using a metal pin
  • 1 × projector
  • 4 × ultrasonic atomizers You can use humidifiers or dry ice as alternatives
  • 8 × 12mm PC fans (90CFM or above)
  • 1 × Used metal fence (got this from the backyard) Metal grates for the fog vents. Could use bits and pieces of corrugated plastic or anything solid as an alternative to hold the fog vents open

    Another interesting aspect of this project is that the hardware also includes fan controllers which allows for fine tuning the fog's density. By independently controlling each fans, the fog density could be improved by limiting the fans' speed to a certain arbitrary degree; the optimal display setting seems to be achieved by making the four fans facing towards you at a higher speed and the other four fans away from you at slower speed. At higher speed, the front facing fans reduce jitter effect while the fans at the back increases the fog's density. If all fans goes on full speed, the jitter decreases but fog density is lower, making the display less opaque and the opposite will occur if the fans goes slower; jitter increases, fog is much more dense meaning more opacity.

Hey @Kenny Nyallau - both you and @Makertum have incredible projects! I don't think anyone was attacking your work - you did a great job.

@Adam Fabio, thanks dude. Haha, that wasn't the case.  My real point is we're making a prototype from the same old antiquated trick, no matter what material we're using. In other words, I'm aware of the history, theory and technical aspects of fogscreen display but what I didn't do is that I didn't just change the type of material and follow one source reference blindly letter by letter; that's not what this project all about. I did my research from varying sources and added a little modification to yield varying results and learn about the pros and cons. That's the whole point of starting this project, for me at least. Maybe I'm overreacting but I just felt the comparison and the "futuristic use of corrugated plastic"  comment by Makertum were a bit condescending, as if that's the only difference that he could observe from my project. But oh well, no harm no foul.

Check out the #Hoverlay II, too

Yes, like I said in the project description, the project is based on previous DIY fogscreen displays and that includes Hoverlay as well but thank you for commenting. Please share.

ps: Unlike hoverlay, this is for people who couldn't afford to have CNC milling machine at their disposal and the fan controllers that I've included can yield varied results on fog density which can affect the display's transparency.
