Introduction: Wooden Cell Phone Projector!
Make a wooden projector for your cell phone. And if you happen to watch the Force Awakens trailer 4 times in a row on your shop wall, well it is Star Wars day so who can blame you!
This one is made from 1/8 Baltic Birch plywood and measures, 6" x 5 1/2" x 3" and has a lens savaged from an old projector.
Step 1: Cutting Your Stock
So the idea for this project came from an old projector I found in a tech warehouse. I brought it back to shop and removed some of the bits. One lens in particular seemed of use. Wait you don't have a slide projector from the 1970's?! A magnifying glass lens from the local dollar tree would also work!
The wood is just 1/8 birch plywood. The dimensions were for my iPhone 5 with an otterbox case. You will need to size your box for your phone.
bottom & top = 5 1/2" x 6"
Sides = 3" x 6"
Front and Back = 3" 5 1/4 (to allow then to be inset from the sides and top)
Step 2: Side Decorations
The side decorations are copied from a picture I found of the death star panels. http://www.niubniubsuniverse.com/download/Download...
I simply put the image into Inkscape and created an SVG file for my CNC to cut out. It's a bit of a process and probably too much of a side track for this Instructable. Regardless it made a nice design.
I painted it with dark gray paint, and sanded it off to give it the look in the photo.
Next I cut a window in my two side panels on the scroll saw to give the project some depth. Otherwise it's just a rather boring looking box.
Step 3: Front Lens
The front lens was about 2 3/8" in diameter. I only know that because that's the size forstner bit I used to make the hole, and it was almost a perfect fit.
Now I made a mistake by messing with the lens and scratching it all to hell. I was attempting to remove a tiny scratch and instead destroyed the lens. I would suggest you skip this step altogether
I had to start over and pick another, less functional lens from the projector. It was smaller and more curved. It worked okay, but I think my original would have worked better!
Step 4: Assembly and Finishing Touches
At this point you can just glue the 5 sides together. (not the top!) I used regular wood glue and some cabinet clamps.
While that dried I cut out the symbol for the rebel alliance and put a quick coat of red paint on it.
The next day, when the glue had dried, I added the top symbol with some super glue and gave the whole project a coat of polyurethane for protection.
Step 5: Putting It to Use
Now that everything is dry and finished, let's test this out!
Turn up the brightness on your phone.
Pick your video of choice and set the screen to landscape and invert the image. (on the iPhone I used the "Assistive Touch" setting to accomplish this)
Then place the device in the box.
You'll have to play with the spacing between the lens and the phone to find the sweet spot. On mine, it was about 3" away.
The image wasn't bad. (Though my video camera doesn't film well in low light) I got about a 15" vertical picture on my wall in decent focus.
It certainly will not replace my TV, but it is a fun toy to play with!
We have a be nice policy.
