Light up the night and relax on a comfortable seat you can easy take to your next night out by the fire. 

These super bright NeoPixel LEDs let you change colors and animations with the Adafruit Bluefruit Connect LE app. This customizable 3D printed design can easily hold up to 200 lbs of weight.

All of the electronics are mounted inside and on the bottom of the seat with plenty of room to add custom parts to the design.

Prerequisite Guides

We suggest walking through the following tutorials to get a better understanding of NeoPixel LEDs and soldering.

Circuit Diagram

Wired Connections

The circuit diagram above shows how the components will be wired together. This won't be 100% exact in the actual circuit but it's a very close approximation. 

Solder all of the sides together except the last DIN and DOUT, leave those two last ones separated. DIN is where the data will feed into the neopixel ring. 

  • 5V+ Power on NeoPixel ring to BAT on Adafruit Feather.
  • Ground on NeoPixel ring to GND on Adafruit Feather.
  • DIN on NeoPixel ring to Pin 6 on Adafruit Feather.

Arduino Libraries

To use the Daftpunk BLE sketch you'll want to make sure you're using the latest version of the Arduino IDE (1.6.12 at the time of this writing).

If you're totally new to Arduino take a little time to go through some introductory tutorials like how to make a LED blink.  This will help you understand how to use the IDE, load a sketch, and upload code.

Next you'll need to make sure the libraries used by the sketch are installed.  With the latest Arduino IDE you can use its library manager to easily install libraries, or check out this guide on how to manually install a library.  You'll want to install the following libraries:

  • Adafruit BluefruitLE nRF51
  • Adafruit NeoPixel

Search for the libraries in the library manager and they should be easy to find and install.

Adafruit AVR Boards

Next, you'll need to install the Adafruit AVR boards package from the Boards Manager. Open the Boards Manager and search for Adafruit AVR. This includes all of the boards from Adafruit and will make Arduino compatabile with them. The Daftpunk BLE sketch was tested with version 1.4.0.

Uploading Sketch to Adafruit Feather BLE

This sketch will run the Bluetooth controlled LED program to the NeoPixel strips that are mounted to the front of the visor.

To load the sketch make sure the libraries above are installed, and the Arduino is connected to the computer through a USB cable.  Under the Tools -> Board menu make sure the Adafruit Feather 32u4 is selected, and under the Tools -> Port menu the serial port for the Adafruit Feather is selected.  

Then press the upload button or click the Sketch -> Upload item to send the code to the Arduino.  Woo-hoo the sketch should be running.

Connect Adafruit BLE Mobile App to Adafruit Feather BLE

Download the Adafruit BLE Connect app for iOS or Android. Under the peripherals list, tap theconnect button on the Adafruit Bluefruit LE item. Make sure the Feather board is powered on. Select "Controller" and choose either Control Pad or the Color Picker.

Control Pad

Buttons 1-4 will trigger an animation.

  1. larsonScanner
  2. color wipe
  3. rainbow gradient
  4. rainbow cycle

Color Picker

Here you can change the brightness or RGB value of the leds. 

Make sure to have a data cable and not a power only USB cable.

You'll want to update the number of neopixels to 60. 

Change this line to:

#define NUMPIXELS               60

    FACTORYRESET_ENABLE       Perform a factory reset when running this sketch
                              Enabling this will put your Bluefruit LE module
                              in a 'known good' state and clear any config
                              data set in previous sketches or projects, so
                              running this at least once is a good idea.
                              When deploying your project, however, you will
                              want to disable factory reset by setting this
                              value to 0.  If you are making changes to your
                              Bluefruit LE device via AT commands, and those
                              changes aren't persisting across resets, this
                              is the reason why.  Factory reset will erase
                              the non-volatile memory where config data is
                              stored, setting it back to factory default
                              Some sketches that require you to bond to a
                              central device (HID mouse, keyboard, etc.)
                              won't work at all with this feature enabled
                              since the factory reset will clear all of the
                              bonding data stored on the chip, meaning the
                              central device won't be able to reconnect.
    PIN                       Which pin on the Arduino is connected to the NeoPixels?

3D Printing

Download and 3D Print

The 3D printed parts can be downloaded with the link below. 

Materials & Slice Settings

This design requires a 12 x 12 inch bed size. If your 3D printer isn't capabile of larger sizes, you could print the pieces separately and glue them together.

The stool legs use TPU material, so will need an extruder capable of printing flexable filament.  Reference the slice settings in the table below – We're using Simplify3D to slice the parts.






PLA 245c  / 60c bed

No supports

30% infill

2mm Z-Hop

90mm/s print speed

120mm/s travel speed

Infill angle offsets:
45, 60, 90, 120, -120

We used a 6mm brim to insure the bottom doesn't curl up while printing.

The seat part take about 30 hours to complete.

Z-Hop is used to prevent any collisions with the print head and any edges that might curl up.

We used infill angle offsets to increase the strength of the seat.

The stool feet are printed in original Ninjaflex to make them grippy, but you could also use semi-flex or cheetah.

Increase infill strength 

We utilized the 3d infill technique by cetting the infill angle offsets to 45, 60, 90, 120, -120. This will alternate how the infill is stacked on top of each other, giving the seat more strength.   

Assemble 60 NeoPixel Ring

The 60 ring neopixel rings come in quarter sized sections that will need to be soldered to each other to make the full circle. We recommend using multiple third helping hands to hold the four pieced together while soldering.

Connect 1/4 NeoPixel PCBs 

To solder the quarter pieces together, start by tinning each side and then carefully slide the solder from one side of the pad to the other, making sure both pads are connected. It will take some practice, but you’ll quickly get a hang of it.

Solder Wires

Solder all of the sides together except the last DIN and DOUT, leave those two last ones separated. DIN is where the data will feed into the neopixel ring. 


Thread wires to the other side

We can use to small opening near the mounts on the bottom side of the seat to thread the wire into.

Ring Cover

Place the ring face down so the lights can diffuse the seat from the top down. The cover snaps on top to protect and secure the ring in place.



Measure and Cut Wires

Place the Feather board on the mounts and then measure wires for power, ground and data to connect the neopixel ring.


Use flush cutters to trim the wires with a little bit of slack, you can always recut them if they are too long.


 Strip each wire to prepared them for tinning.

Tin, Solder and Screws


2.5mm screws are use to securely hold the feather board on the four mounts. We recommend tapping each mount before securing the board on top.


Now we can tin, solder and solder each wire to the board. Connect power on the neopixel ring to 3v on the Feather board, Ground to G and DIN to Pin 6 on the Feather board.

Slide Switch


To easily power the circuit on and off we’ll use a slide switch. We’ll get the switch ready by tinning two of the leads and soldering a wire that will connect to the EN pins and the Ground pin.


Since this will be the second wire soldered to the ground pin, it’s easier to solder this wire to the top.


Tweezers help to maneuver wires into place.


 To power the circuit we can fit a 2,000mAh battery in the slot close to the board. It should have a tight fit, but we reccomend using double stick foam tape to secure it place.

Load Sketch

Plug the micro USB cable into board and your computer to load the sketch.


Make sure to have a data cable and not a power only USB cable.

The Adafruit Bluefruit app connects to the feather ble board and works on iOS and Android devices to update colors and animations on the LEDs. You can find them on the Apple App Store or Google Play Store.

Rubber Feet


Three 7/8 inch dowels use rubber ninja flex feet to keep them from digging into soft surfaces and from slipping on hard surfaces.


Align the triangle support frame to the three slots on the seat and then fit each leg through the frame and into each slot.


Level Legs


If the tolerances are a little loose you can use making tape on the ends to get a tight fit in the slots.

Make sure all of the legs are level and you're ready to sit!

Customizing and printing your own furniture is a lot of fun, but adding electronics is really rewarding. You can build on top of this design to make a seat that can change colors based on weather or even flash when you receive different alerts from twitter or github repos.
