Introduction: Pandora

Reinterpreting the reed's wading with light.

Step 1: Concept


In order to express the reeds of the reeds, the HSV color space was mapped in three dimensions. In order to digitally perform the reverberation of the reeds, it uses the space of H (hue) 360-degree color wheel in the bending direction and S (Saturation) in the direction of the bending angle to naturally express the natural fluctuation by the LED.

Step 2: How It Works

Bended Angle = Specified Saturation.

Bended Direction shows Color Change.

H(Hue) Hue 360 degree color representation on the color wheel

The higher the bend angle, the higher the saturation of S(Saturation)

Step 3: Prepare Parts

1 : Acrylic bar 10ø(Outer diameter ), Height 300mm

2: Modeling parts by printed 3D - printer (stl file)

3: Electronic parts

3-1 Neopixel

3-2 MPU-6050 Sensor

3-3 Arudino Nano

4: Aluminum pipe 10ø(Outer diameter ), Height 1250mm

5: Rubber bushing 10ø

6: Rubber stand 10ø



a: Soldering Iron

b: Dupont Cable

c: Lead

d: Many times



Step 4: Arduino Upload & Electronic Parts Wiring

First, download the attached source code.
(Include in Arduino default library Wire, Adafruit_NeoPixel.h, MPU6050.h library)

Image 01_Electronic parts connection

Wire Arduino nano boards, sensors and neopixels as shown

Step 5: 3D Printing & Pipe Processing

01_Print the attached stl file to a 3D printer.

02_Cut the outer diameter 8 pie inner diameter 7 pie aluminum pipe to 130cm. x32 set

03_Cut an acrylic pie 10cm long and 30cm long / Sand the acrylic rod like the attached photo.

Step 6: Assembly Process

Image 01_3d print the attached stl file
- Attach the prepared parts to the 3d printer printout as shown in the photo (Be sure to align vertical and horizontal). - Align 3-1 neopixels with the top part holes for light diffusion. - Finally, Assemble parts # 2 and # 3 and insert # 1 and # 4

1- We'll fix the neopixel square leds into the square holes in Part 2-1

(mentioned in step 3 The upper part output to the 3d printer)

2- Apply adhesive so that it is completely fixed.
(* Caution- Apply around to avoid contact with led)

3~4 - Fix mpu-6050 and 2-1 parts using adhesive as shown in 3,4 image

5- Solder wires to Arduino Nano to connect to power supply

6~9- Pass the power line through the aluminum pipe

10~12- Bond the acrylic rod to the top part

Step 7: How to Connect the Power

Step 8: Power Wiring_1

1. Power Supply 5v 10A

2. Wire according to +,- of each set.

3. Insert the power cord into the pipe and fix it in the acrylic box

Step 9:

Step 10: Power Wiring_2

4. Secure all pipes in the same way. Only the +-lines that power the Arduino nano should come out.

5. Connect the assembled parts to the power line.

6. Last step: fasten each part with adhesive
