Rings of Saturn LED Music Visualizing Pendant Light




About: I am a DIY hobbyist who loves making things, especially with wood and concrete ( and recently, LEDs). Subscribe to my YouTube channel for more builds: https://www.youtube.com/c/ModustrialMaker Follow m...

I made this LED pendant light from plywood, LED strips, and flexible LED channel. Since I designed this for my living room, the music syncing had to be incognito. With this in mind, I used warm white / cool white / amber LED strips, instead of RGB strips. In solid white mode, the rings give off various shades of white for a sophisticated modern look that hides the wild side when you switch the light to music visualizer mode

The build is fairly simple. Each of the two rings is made of a stack of three plywood rings, where the middle ring has a lesser radius to create a groove for the LEDs. The rings are simple to cut using a circle cutting jig and router. While I programmed an Arduino to do music visualization based on input from a microphone, you can very easily buy an off-the-shelf music controller for individually controllable LEDs, which is basically plug n’ play for LED strips.

I've included most of the parts for the build below, and the video walks you through the build process. I will come back and update this instructable with more build details soon. Or, feel free to leave any questions in the comments section and I will be happy to answer.

Links to off-the-shelf LED controller and lights (this makes the mode switching, music syncing LEDs way easier to install), but note you'll need a separate controller for each ring.

Use the above controller with one of the following three types of LED Strips:

- individually controllable warm white / cool white / amber (WWA) LED strips: http://amzn.to/2fnCv5d

- Individually controllable temperature varying warm white LED strip: http://amzn.to/2fnCv5d

- individually controllable RGB LED strip:

Step 2: Cut the Rings

[Note - the pictures show a jig saw, but I used a router with circle cutter jig. I had a couple errors as a result of not having a router bit long enough to go all the way through two 1/2" pieces of plywood. Make sure you get a router bit that is 1.25" long and you'll avoid this.]

Each ring is actually a stack of three rings that are glued together. The top and bottom rings in each stack are identical, and made from 1/2" walnut veneer plywood. The middle ring is made from 3/4" standard plywood (it isn't visible), and the diameter of the middle ring is 1" less (i.e., 0.5" less radius) than the top and bottom rings, so the stack forms a channel for the LED profile.

Cutting the rings is easiest with a circle cutting jig.

Stack the 1/2" walnut plywood sheets and screw them together, so you can cut the top and bottom rings at once.

When cutting each stack of rings, you'll want to work from the outside in, so cut in the following order:

1. Cut the outer radius of the top and bottom rings from the walnut plywood. (I cut them at 42" diameter.)

2. Shorten the distance to the router on your circle cutting jig by 0.5" (so diameter of the resulting ring is 1" less), then cut the outer radius of the middle ring (I cut at 41" diameter.)

3. Shorten the circle cutting jig by another 1.5" (so diameter is 40"), then cut the inner radius of all rings.

Then repeat steps 1-3 for the smaller ring.

Step 3: Glue Up the Rings

Stack the 3 rings and use wood glue to glue them together. Take your time and try to make sure the inner radius is as flush as possible on all three rings.

Step 4: Apply Edgebanding

Use 3/4" (or 5/8" if you can find it) walnut edgebanding for the outer radius of the top and bottom rings in each stack. I actually applied edgebanding to the outer radius before the glue up, but I think you can do this after glue up just as easily.

Use 2" walnut edgebanding to cover the inner radius. If the inner radii of all three rings in each stack aren't perfectly flush, you'll want to sand them flush before you do this. A belt sander is useful for this, but you can use any type of sander to get the job done.

Step 5: Apply the Finish

I applied two coats of danish oil to each ring stack

Step 6: Add LED Strips

Cut a chimney-like hole thru the middle channel and out the top of each ring to make a path for wiring to LED strips.

Use the adhesive backing on the LED strip to adhere it to the middle ring in each ring stack. Optionally, use some CA glue to make sure LED strips don't come unstuck.

Step 7: Install Flexible LED Channel

I cut the back out of the LED channel, so that I could adhere the LED strip to wood ring directly, and have more space between the LEDs and the diffuser on the channel. This results in better light diffusion and a more solid look to the light (instead of the dots LED strips often produce).

Then I bent the LED channel to the rough shape of the ring, cut it to size using a miter saw, and used CA glue to adhere it to the channel formed by the stack of three rings. I used electrical tape wrapped around the ends of the channel to make sure it stayed in place while the glue dried.

Step 8: Program the Arduino and Install the Electronics

This could be the basis of an entire Instructable on its own. I was learning as I went, and went through many iterations of electronic configurations. Ultimately, if you want to simplify this build use the off-the-shelf controller and remote I linked to above. If you are interested in building the electronics yourself, here is a link to the code I used (warning, it is very crude): https://github.com/modustrialmaker/Rings-of-Saturn-LED-Light-Music-Visualizer

Question 11 months ago on Step 1


Would you be interested in making a linear LED PENDANT for me? I would obviously pay you for your work.

I am interested in making a light that looks something similar to this:

Except a linear pendant- like this but with crystals shooting up and down only like they do in top photo. I dont need metal base- can be wood...

I have never attempted actually creating LED light connection- so would like you to make me one like this (60" long)

And I would glue in the crystals...

I cannot seem to find a light that directs light UP and DOWN (all of these seem to shoot down only) and i think it would be cool to have the light shine up into the quartz crystals.

My question is- do you have interest in helping me create this?

If you create the light and guide me as to whats the best way to glue the crystals and I glue them in?

Could you make a linear pendant with 2700K LED strip shooting to ceiling and to ground with side panels in metal or wood?

If you cannot do this do you know some one who could?

I'd like to know what kind of metal wire do you use to support the circles. There is no link to it. Thanks

Absolutely phenomenal build. Kudos, and thanks much for sharing.

You should totally make one using those Hue strips or something.

Very nice work. Do you think same could be done with two bicycle rims?

There is actually a kickstarter project that I backed for something like this. http://www.monkeylectric.com/

Putting LEDs on bike wheels is trickier since you have to use battery power.

This looks cool ... and easy to make, actually, thanks for a perfect idea!

One question, tho: how much light does it give with the LED strip you used? Is it to light up a bedroom enough for reading, or just for ambiance, please?

Really cool, definitely deserved the vote!

I had seen a number of the simple ring chandeliers on design blogs, and the idea to make it out of walnut (which I've not seen before) was just to match my living room furniture. I thought it would be cool to do LED animations in the ring light as well, but my girlfriend put her foot down that "we can't turn our living room into a night club." Thus came the idea to use the WWA LEDs so that the light would appear as a normal warm white light, when the music visualization mode was turned off.

Thanks for the kind words. Still much to learn though, especially when it comes to electronics...
