Hello, dear readers and homemade products!
Recently, more and more various lamps based on LED strips have appeared. It is not only a very economical light source, but also the possibility of smooth adjustment of brightness and color tone. In addition, you can create a variety of lighting effects, for example, to the beat of the music.
In this article, the author of YouTube channel “Modustrial Maker” will tell you how he made a pendant LED lamp “Rings of Saturn.”

So, the main material for this project will be multilayer plywood. Several rings are cut out of it, which are then folded in a pile and glued together so that a channel is formed for an addressable LED strip.
The tape can be controlled using an arduino, but instead it is much easier to use ready-made addressable tape controllers with Bluetooth control, or Wifi … They already have a built-in effect module that adjusts the lighting to the musical rhythm according to a given program, or performs a simple adjustment of brightness and color.
To cut circles, and then rings, a hand mill with a special circular nozzle is used. About its production there have already been articles on this site.
First the author cuts two half-inch sheets of hazel plywood. He cuts both outer rings at the same time.
Then the inner ring is cut. The inner radius of all rings is the same, but the outer radius of the middle of the rings is 10 mm less than the same size of the other two.
Now the craftsman moves on to cutting out the rings with a larger diameter. The cutting order for each type of ring is very important. First, the outer radius of the upper and lower rings is cut out.
And then the outer radius of the middle plywood. This radius is about 10-12 mm less than the top and bottom layers.
And only after that should one proceed to cutting the inner radius of all three rings at the same time. This way you can be sure that all three rings will be centered on the inner radius.
In the next step, an edging tape is glued to the outer radius of the hazel rings. This operation does not have to be done with an iron. The master uses an industrial hair dryer and a roller for rolling. This method turned out to be no worse than an iron.
The protruding edges of the edge are cut with an edging knife.
Next, the author proceeds to gluing. As you can see in the photo, the top ring was cut into two halves. This was done to save material.
All three parts are compressed with clamps, starting from the joints of the halves of the upper ring.
When the glue has frozen, the author removes the clamps and starts grinding the inner surfaces first. < br> A belt and orbital sander had to be used to machine the large ring. And then complete the process by hand sanding.
After that you can start edging the inner radius of the rings. A 50 mm walnut veneer is used as an edging tape. The edging technology remains the same: an industrial hair dryer and a rolling roller.
Excess material is removed with an edge trimmer, and the edges are rubbed with sandpaper by hand.
Again, a quick sanding, as a result of which the veneer peeled off the author in several places, so I had to apply a putty under walnut wood.
Next, the master applies a layer of Danish oil (made from tung or polymerized linseed oil) on all surfaces, thereby showing the veneer texture, and protecting the wood from moisture.
All the same processing stages go through the blanks for a small ring.

In this project, a flexible LED neonizer channel 20 mm wide and about 12 deep is used. This means that when cutting the inner ring of a sandwich structure, it should be cut 12 mm less than the outer radius. If you use 20 mm plywood, you create an ideal trough for the LED strip.
I recommend paying attention to the flexible neonizer channels used by the author. They perfectly smooth out the point light from LEDs, giving them a uniform “neon” effect.
There are a lot of varieties of the profile of such channels. They can not only scatter, but also redirect light in the desired direction. They also provide good heat dissipation from the tape.
When both rings are ready, it is time to drill holes for the power and signal wires on the side and bottom of them. When you start making the hole, make sure that it is located on the upper, invisible side of the rings.
A wire is threaded through the hole and an LED strip is glued into the groove.
in this case, it is the wrong decision. The ribbon must be installed inside a flex channel.
Since the tape is already glued to the ring, the author had to cut off the back wall of the canal. < br>As a result, only the diffuser remained of the complete system. It will help to ensure that the LEDs do not look like separate luminous points, but are perceived by the eye as a single luminous strip.
Now the diffuser is glued into the groove with cyanoacrylate glue. The most important thing is to precisely bring the joints together.
All the same operations are repeated with the second ring.
Finally it was time to install the harness. The 4 brackets should be placed on the top of the ring so that they are equidistant from each other. In this case, the chandelier will be balanced.
Having completed the markings, the author drills holes for the fastening accessories.
Attachments for cables are screwed into place.
Alternatively, the cables themselves can be used as power wires for the LED strip. This can reduce the amount of conspicuous detail.
So, all the pendants are in place. Ropes are passed through them, and the chandelier is mounted to the ceiling. In this case, to a wooden beam.
The master used a two-color address tape, which has only cold and warm white LEDs .
Of course, you can install a full-color address tape instead.
To control the tape, a music controller with a pass-through audio channel, or controllers with a built-in microphone are suitable.
Power supply of address tapes is most often carried out from a voltage of 5V. With a long tape length, power should be supplied from both sides, and the signal wire is always connected only at the beginning of the tape.
By the way, the Chinese have already started production of similar chandeliers in the form of rings with hanging system .
Thank the author for the carpentry version of the “rings of Saturn” chandelier.
Happy New Year mood, good health, and interesting ideas!
