The instructable is http://www.instructables.com/id/Cheap-simple-media-projector-with-a-recycled-ike/ and is about transforming an ikea lamp into a projector.
In a year a lot of things happens:
- I get into the DIY universe
- ponoko (the online lasercut service) open a factory in Italy near where I live
- I bought a Lomo Camera (http://lomography.com) and discover how cool are 35mm cameras
This project reflect all these changes. I'll show you how to buil a lo-fi projector to display your photo slides on a huge wall. The lo-fi aspect is crucial to lineup to the lomography way. The fact that the project is also cheap is a plus! Sadly, the ikea lamp I'm using ( isbrytare ) is out of stock and no more produced. You have to found in used or hope that Ikea will start again producing this beautiful lamp. Its cost was about 40$.
The lamp became a present for the birthday of a very good photographer and friend: Fizza (http://www.fizza.it/)
Finally I'll give one or more patches to the best comments/improvements to the project you will post.
If you are interested, you can view the list of my not-yet-realized ideas on my blog
Step 1: Material needed
- isbrytare lamp from Ikea (ikea.com, no more in production.. find it on ebay)
- plans to build the adapter (downloadable in the next step)
- something to cut wood if you are planning to build it by yourself OR an account on an online laser-cut service (i use http://www.vectorealism.com)
- vinilic glue
Step 2: Cut the wood for the slide holder
Now you have to choose how to proceed:
- you can give the file to an online laser-cut services and let them to made the work for you. They will precisely cut the pieces and send them to your home. I suggest you to use 1/8 inches wood (mine is actually 3 millimeters)
- you can print the files on paper and glue the paper on thin wood as a guide for your cutting lines
If you choose the former, I suggest you to choose ponoko.com simply because files are already formatted for that site.
If you choose the latter you maybe need some more info:
A file with SVG extension has a particular format named VECTORIAL that allows you to describe an image with mathematical formulas. In other words, you can zoom the image as you wont without loosing quality. If you do not know how to open these file just download the open-source, multi-platform and free software http://inkscape.org/
Step 3: Assemble the slide holder
- Step 1: glue part A to part B. Be careful to not exceed with the glue and to align the center hole of the two pieces
- Step 2: turn the obtained piece and glue part C. Be careful to align the central hole and the side holes. (the order of the wood layers should be A - B - C)
- Step 3: glue part D over part C again being careful to align holes
- Step 4: leave the glue to harden for 24 hours
Step 4: Attach the slide holder to the filter holder
- Put the filter holder of the lamp over Part A of the slide holder.
- Fasten the to 2 screws until the two pieces are firmly together.
Step 5: Assemble the lamp and focus
Power the lamp and point it to a big wall. Move backward and forward the 2 pieces until the image on the wall is on focus
I also added a wood floor to the lamp so that it can stand by itself.
Enjoy your new photo-slide projector
