Picture of Optical fiber flashgun
In this experiment I tried to find possible ways of guiding and shaping flashlight with the help of Plastic Optical Fiber.

Step 1: Ingredients

Picture of Ingredients
• 9 optical fiber light, I tried to buy only the plastic optical fiber on spool (POF), but I found only very expensive ones. These ones you could buy in these 2 euro shops or Chinese market. Image credit
• thin plywood
• 1 straw
• paper adhesive tape
• wood glue
• transparent sandable epoxy resin for plastic
• punctured bicycle inner tube
• sandpapers with different grades
• velcro
• fretsaw
• and of course your favourite flash light

very good instructable!! loved your photos & videos, easy to understand instructions. You should hurry & enter the light contest!

I did something like this with plastic optical fiber a few years ago. I took the fiber ends out to a ring I cut out of a plastic (translucent white) cutting board, and mounted the ring on a step-up ring that I could put on my lens. It made for a great ring light.

Very good, maybe you share a photo of your gadget and image you made with the ring, so it could be usefull for others as well...or you can make an instructables.
I wish I had taken photos while I was making it. I have thought about redoing it and making an instructable out of the V2 build.
I'll dig it out and take a picture or two tonight though.

...maybe just distort image and play with.

And if you do this to increase the size of a phone screen?
With this end tightly bound you might also have been able to melt and fuse the ends, pressing the molten end against a flat surface to flatten it.

You can't melt the tubes, because you mess up the way light enter into the fibers.
Have you tried it? Fusing optical fibres is often done in industry. Adding glue is not a lot different because of the similar refractive indices.

Thanks, it is a good feeling to "bend the light" with your hand, hopefully it could be more practical with the second prototype

Very clever, could be really cool for some photography setups -- almost looks like 'light puppetry'. Oh, and nice .gifs!

I guess for real photographers, they would be concerned with how much light gets through the fibers to see if it is really useful for illumination. It also might change the color temperature of the light too acting as a filter. But thanks for sharing though.
