High power LED slide projector for old camera lenses

Ok so this is not my project this i discovered on instructables and thought to share it with you soo letss get to it !

If you have old camera lenses, a macro bellows and a high power LED flashlight, you can use those to build a battery powered projector.

Depending on lens and light it can be very powerful.

Step 1: Prepare the bellows

You will be cutting slits into the bellows in order to position the 35mm film just where it would be in a camera or slide projector.

In order to do that, just extend the bellows halfway and measure a distance of 44mm from the lens flange. This should be within +/-3mm to the exact flange focal distance of your lens (you can adjust it with the bellows)

Now make two incisions to the left and right side of the bellows, and insert the 35 mm film.
Just be careful to make them horizontally centered, symetrical, and not too wide.

Insert the 35mm film with the image bottom-up.

Step 2: Attach the flashlight

You will have to find some way to attach your flashlight.

I used M42 extension tubes and gaffer tape, you might find another solution. Whatever works :)

Step 3: Start projecting

Congratulations! You should have a working projector.
