Just for fun I wanted to make this "add-on" look as if it belonged to the original projector by painting the LCD package with metallic "hammered texture" paint. I also framed the LCD screen with an original vintage "Kodak Kodachrome" slide holder.

This projector is what the A/V crew back in public school only could dream about! so....
Step 1: The Projector...
The original slide attachment slid onto the projector on two metal rails. The piece that held the attachments was removable so I could use it to hold my new LCD conversion.
Step 2: The LCD...
I decided to still use this device as the size of the package made it easy to work with. I had an older digital camera that I pulled apart to see if I could use its LCD screen but there was so much other electronics and functions in it and the ribbon cable to the LCD was so short I could not get it to work. I reasoned that since it was a 1950's slide projector the resolution did not have to be high as that would add to the "authenticity" of the experience.
The first step is to open the key ring and separate the parts from the case.
Step 3: Modifying the LCD...
I left the LCD backlight in place as it is off to the side, and mounted as part of the LCDs plastic frame so it does not interfer with the Leica light shining through the LCD. I have heard that in some devices the logic detects if the backlight is not working and shuts down the LCD. I did not want to take that chance so I left everything in tacts except for removing the covers from the back of the LCD to allow light to shine all the way through.
Note:Slide projectors actually invert the image when projected. To compensate for this I just flipped the images in photoshop and relaoded them into the Key chain.
Step 4: Build the LCD Holder...
Step 5: Putting It Together...
I needed something to hold the Key ring case to the light switch plate that could also be removed in order to plug in the USB to recharge the Key ring and to load new pictures. I thought of several options but I wanted something low tech to fit with this project so I just bend a piece of metal to act as a "clip". It held the case firm but was easy to remove and did not look out of place on the device. Lastly I touched up the screw with a bit of the spray paint to blend it in.
Step 6: Ready for the Show!
The picture was better than I originally thought but was still pretty pixilated. The key ring automatically rotated through the images switching every 15 seconds, It was difficult to take good pictures of the slide show as room had to be dark to project the image on the wall. I was projecting the images onto a piece of white cardboard that was 3'x4' and the picture itself was about two feet wide at a distance of about 8ft from the projector.
The best part of this attachment is how inconspicuous it looks. Someone just looking at it would think it was an original attachment from the 1950's.
This is the perfect way to watch childhood photos with your family at holiday gatherings!
