How do i build a weatherproof, dust proof video projector enclosure with good airflow for use in a desert enviroment?

I'm going to be using a projector in the desert at night and need to build an enclosure for it. The enclosure will have to have a serious filtering system to keep blowing sand and dust out, it also will have to be able to block any rain that just might fall. While doing all that it must push alot of air out of the box to keep the projector cool enough. It does NOT need climate control because the desert gets really cool at night when ill be using this unit. Ideas?

Try projector from Lumitrix.eu.

Its a only solution for outdoor projections.

Build the case with a heat exchanger.

You need two fans.

Take a sheet of corrugated plastic sheet - we buy it as "correx" board
http://www.teacratepackaging.co.uk/correx-board-p-88.html for example - 10 USD /sheet.

Cut it into strips., as long and wide as your extractor fans, cut enough strips that you can make a pile almost as tall as your fan.

Stack the strips with pieces of card or plastic, and use double sided tape to make a stack of strips which will have gaps between them.

That's the exchanger.

Mounting is tricky :-(

Arrange the thing so that warm air from inside your case is blown through the exchanger AND RETURNED TO THE CASE WHICH IS SEALED.

I'll try and do a sketch when the IT guy has worked out why he has trashed my Design system.....

Hi Steve,

Any chance the sketch is still around? I'd like to build something for use in the desert.as night as well and don't really have a visual in my mind of the exchanger you're describing. How does this help with the dust?

The inside air is sealed from the outside air, only the heat is moved from one to the other.

Hmm let me see if I understand - hot air flows out from the projector box into a 'tube' -the exchanger - and the heat passively equalizes through the plastic?. Then air flows back into the projector box?

Or is this totally misunderstanding you?

No, basically correct. You can do it with a few copper pipes in your box wall too.

hi there, this post is very old, but am curious if you ever did do a drawing for this? I need to weatherproof a video projector also, for a 6 week installation in england. So problem is not so much dust, but dew, condensation, heat and humidity.
I have some ideas for running a fan with arduino and/or raspberry pi.
Curious to hear from people that have already been down this route before??
thanks

This weatherproof enclosure for a projector has recently been launched which is actually made in the UK. It is IP rated and CE-marked - its made by VIZBOX if you want to look them up.

I think I may have a copy. PM me an email address

This company in the UK actually manufacture outdoor projector enclosures which will do everything you need.

My company purchased one of your boxes for an outdoor projector in the UK, once the housing was installed we had light rain fall overnight and in the bottom of the vizbox enclosure was a pool of water around 20mm deep! We drained this out and checked the day after, before installing the projector. The client called a few days later to inform us the projector had been stolen!! I was sent to site and found the locks had been opened WITHOUT the key and the £2,300 projector stolen!

We are an AV company and have installed expensive projectors in the Nevada desert and yes, you do need cooling and heating to ensure the projector does not fail - it is a very expensive mistake it the projector breaks down due to dust or over heating.

We found a company who specialize in manufacturing outdoor projector enclosures that was cost effective.

They are weatherproof and best of all vandal proof! Had to replace so many projectors before we found this source due to them being stolen.

Hey there... There's a neat, cheap little projector that may do the trick if you're projecting in very dark setting:
http://www.UltraProjector.com
It's weather-proof and has built in video player so it doesn't require any external pc or video source (which you'll also have to weather-proof).

As you said: Filters and fans. Big filters and big fans, probably, to get enough cooling. Draw and exhaust air from underneath to avoid drawing water in, preferably with drip barriers so any water which runs down the outside drips off before it gets to the intake. You'd best check what the actual dust size is before you select your filter. You might be able to get by with, for example, furnace filters... or you might need something a lot more serious. Beyond that... I think you've bitten off an interesting challenge here.
