This is small circular ring of addressable RGB LEDs (12 total). Great for many maker projects.

This is a small circular WS2128 Addressable LED strip with 8 individual RGB LEDs available.

This is small circular ring of addressable RGB LEDs (24 total). Great for many maker projects.

Round and round and round they go! 24 ultra bright smart LED NeoPixels are arranged in a circle with 2.6" (66mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you're ready to rock.

With a slip ring assembly, your electronics can now twist and turn safely. Add wheel encoders, 360 degree sensors, rotating LEDs, rotors and more! We've seen a lot...

This is a 6 wire slip ring, a remarkably simple electromechanical assembly that allows electronic signals to be passed through its rotating innards. Commonly, you’d find slip rings in wind turbines, radar antennae, or anything else that requires continuous 360° rotation while maintaining an electrical connection. This particular slip ring provides you with a compact body with gold-on-gold alloy fiber brush to plated ring contacts inside.

This is a 12 wire slip ring, a remarkably simple electromechanical assembly that allows electronic signals to be passed through its rotating innards. Commonly, you’d find slip rings in wind turbines, radar antennae, or anything else that requires continuous 360° rotation while maintaining an electrical connection. This particular slip ring provides you with a compact body with gold-on-gold alloy fiber brush to plated ring contacts inside.

This WS2812B ring lamp is composed of 93 lamp beads in 6 circles, and each circles can be controlled separately. You can design the size and shape of the lamp as...

The biggest NeoPixel Ring yet! With four of these you can make a huge ring with 60 ultra bright smart LED NeoPixels are arranged in a circle with a 6.2" diameter. Each order comes with just the quarter ring. Four of this item are required to make a large ring. You will have to solder them together as well, so for the full ring of 60 LEDs, buy four and solder them together!

Add rotation and sliding to your cardboard creations!

This is a 3 wire slip ring, a remarkably simple electromechanical assembly that allows for electronic signals and power to be passed through its rotating innards. Commonly, you’d find slip rings in wind turbines, radar antennae, or anything else that requires continuous 360° rotation while maintaining an electrical connection. This particular slip ring provides you with a compact body with precious metal alloy fiber brush to silver plated ring contacts inside. We like using these slip rings to specifically transfer power in our spinning projects because regardless of the wires position in its rotation the power remains consistent!

What did Lord Sauron, when forging the One Ring in the fires of Mount Doom forget to include in his all powerful ring? What did he forget to leave out of the ring impervious even to dragon fire, designed to rule over all free peoples of Middle Earth in perpetuity - a ring destined to be the One Ring to Rule Them All, to tempt its wearer with the promise of infinite power? Thats easy - it could have used an embedded RFID/NFC transponder!
