Instructables
This is my first time using Arduino, or any microcontroller. I'm glad it worked out so well but my wife may not be, due to the stacks of microcontrollers that will being showing up on our doorstep soon for future projects. Any feedback or questions are welcome, as are votes in the Arduino Contest.

Why (Problem)
I love watching sports, my family loves watching sports, and we all love cheering on our local college team (Go Dawgs). This leads to lots of watch parties on game day. Since there are usually upwards of 15 people we use a projector so everyone has a good view. The downside is the screen. In the past this was just a white sheet tacked to the wall. This was decent but left a lot to be desired.

What (Solution)
A motorized, Android and Arduino controlled, Bluetooth enabled, screen. The screen itself is made of white blackout material, giving a smooth bright projection surface. The whole unit is stored above a drop ceiling which the screen is deployed through, into the room (if you don't have a drop ceiling where you use your projector don't worry, you can just mount to the ceiling or wall).

New Screen Pros
  • Storage - With a push of a phone button the screen is stored out of sight, in the ceiling.
  • Setup - With a push of a different button the screen is deployed and ready for use. No more thumbtack holes in the wall or ironing a sheet that was folded up and creased.
  • Picture Quality - The blackout material screen does not allow projected images to show through to the back or let ambient light from behind seep through. Also no more having to iron your sheet/screen before use or waves and wrinkles in the screen.
  • Wow Factor - Because it's awesome, enough said.
  • Cost - A similarly sized, motorized screen will run you $300, or up to $1500 for a in-ceiling model!
New Screen Cons
  • Cost - A white sheet from Wal-Mart is probably a few bucks, where as an Arduino UNO alone is close to $30.
Now that we know why we're here, lets get cracking!

Excellent instructable... I like how you used the shaft directly on to the rod...great article!

Thank you, glad you like it! It worked pretty well for the resources I had but I think access to a 3D printer could really kick it up a notch. Some day I may do a second version that's a little less, "prototype-y", if you know what I mean.
Wow, this is very impressive, I noticed we have the same bluetooth dongle and it's making me wish I had a projector so I could build this myself, sadly I don't have a drop ceiling so I'd have to make it look even more pretty and bolt it directly to the ceiling, I take my hat off to you sir this is a very impressive ible.

Thanks! That Bluetooth module is pretty awesome. It was one of the easiest parts of the project to get working. I'll definitely be using it again.
