Effiluxring light

Effilux Adjustable LED Ring Lights provide high intensity and uniform LED illumination, while also providing the flexibility to customize the angle at which the light is emitted. The easy to access lens array allows for quick, manual adjustment of the illumination emission angles. Simply remove the LED window that’s held in place by screws and rotate the lens array to one of the three indicated positions for the various emission angles. Effilux Adjustable LED Ring Lights include three interchangeable windows (transparent, semi-diffuse, and opaline) and an optional polarizer accessory is available to be placed beneath the transparent window for glare elimination. The modification flexibility allows these ring lights to be used in a variety applications.

Lay your cardboard pieces out as pictured. Put a single piece of tape on each side of the front, overlapping with each side.

This is the only tricky part of this project. Fold up your frame on the score lines so the corners tuck into a small V. See the picture for detail. Tape over the V and secure all four corners. When you're done your frame should look like the photo!

Using the template provided, cut out your screen holder. If you use a file folder like I did, cut two pieces and tape them together, this will make it a little more sturdy. Make sure and add your score lines as well. This will be where you fold the holder up into a frame.

Fold all of the pieces over so your box looks like a box. Tape all of the outside edges, trying to cover any light gaps. The darker the inside of your box, the clearer your image will be. You can also cover the outside in dark paper if you choose.

Tape your lens over the front opening. If you angle the handle, the lens should fit without you needing to cut anything.

Using the provided template, cut out all of your cardboard pieces. You can do this using a box cutter, exacto blade or a laser cutter if you've got access to one. Try and keep your edges as straight as possible, it will make joining your pieces together much easier.

Camera Obscura just means dark room! With this instructable we'll be creating a small dark room out of cardboard, cereal box, masking tape and a cheap plastic hand lens. You can use this little contraption to view the world upside down, turn it into a pinhole camera, or use it as a cell phone projector! It's a great tool for teaching kids about how the eye works, how we perceive light, and about translucent, transparent and opaque materials.

Insert your frame into the back of your camera obscura. You can use the handles to adjust the distance between the screen and the lens. Experiment with different distances, different light sources and a darker box. Try turning your project into a pin hole camera or a cellphone projector!
