Lastly, the inside of this thing is a huge mess of wires and ac-dc, dc-dc power converters. I’m hoping that with a better lens, I’ll only need the one. I’m also using 2 transparent diffuser sheets to even out the back lighting. I’m still waiting for a new lens for the LED, but I have now 2 of the original glass lens I can use in the meantime. To fix this, I’ll glue a small chunk of steel weight the leaver and let gravity do it’s thing. The result is the slide isn’t in proper position when the photo is taken.

I’ll likely use a PC computer fan to keep things cool.Īnother thing noticed was that the mechanical arm that drops the slide into place seems to be sticking before it bottoms out.

Because I’ve now used that area where the fan was for power input, I’ll have to install a new fan in another location. I took out the original cylindrical spinning fan thinking it wasn’t necessary anymore and it looks like I was wrong. I’ll try and keep things as descriptive and informative as possible in case anyone in the future wants to build one of these.Īfter running it for a while, I realized that the transformer was getting very hot.

Likely much of this will be changing as I built this. After the projector loades a slide, a controlled delay will be necessary for the slide to stop moving due to mechanical vibrations. The mechanical speed of the projector will be the main limiting factor as taking the photo will be almost instant. It might ended up not being a reliable workflow. (Only take a photo once a slide is loaded)Īt this point, I don’t know if it’ll be necessary to focus the camera each slide.

Electronically controlled air compressor to clean dust from slides.

18mb RAW * 200,000 slides = 3.6 TB (terabyte) of image data.

Adjustable speed/interval for each step per-slide.

Very high rated CRI LED slide backlighting for good color reproduction.

For anyone not wanting to build a DIY scanning solution, this pre-built one is likely your best option. One great example of a professionally built conversion is the SlideSnap Pro. There is very little information out there about converting a slide projector into a scanner so I’ll be figuring this one out on my own as I build it. Existing Scannersīy doing some research, I found a couple DIY slide scanner projects and companies modifying old projectors to do such a task. The way I will be automating this process is to use an Arduino microcontroller to control both the projector and digital camera functionality.īelow is how the internal workings of the projector scanner function as a state machine. What I will be doing is to modify one of these projectors to project the image into a digital camera to digitize the slide. These projector can be loaded with many slides and will step through a set of slides electronically.

Slides are designed to be projected on to a screen with a slide projector.

I would need to make sure all manual steps per side are fully automated.

So taking photos of the slides will be the way to go, but how to automate the entire process? A collection of hundreds of thousands of slides is no small talk. Using a DSLR camera to digitize the slides would be an efficient method because shooting photos can be done very fast, and the RAW camera images are space efficient. Other options were to us a flatbed scanner, but this would take a long time and the 16-bit RGB image files would take up a huge amount of file space. I was looking around on how to digitize this many photos and getting them done in bulk from a service ended up being too expensive.

This is my father’s collection which comprises somewhere around 200,000 slides mostly of train photos over a span of 50+ years. I have taken on the task of digitizing a large collection of slide photography. Currently I have removed all necessary components not needed from the projector, and have wired in some extra electric circuitry power the LED that will be used for backlighting the slides.
