Introduction: FRIEND'S LIGHT_프렌즈라이트
FRIEND'S LIGHT : friendly and interactive light like a friend!
Background
Most lights sold in the market have a structure in which light is emitted from the body. We tried an interesting approach by switching the existing stereotypes and tried to make a concept lighting that is turned on through the head (incandescent lamp). We will be able to appreciate our original lighting combining storytelling, sensing and coding.
This project can expect a variety of series!
Step 1: Idea Sketch
Analyze and research exciting and dynamic poses, and go through several sketches!
Step 2: Story & How It Works
Imagine and set up each story and how it works of 6 poses!
Step 3: Materials
All that you need is:
HARDWARE
1. Arduino Uno R3 (x6)
2. The Customized Module : AC to DC Converter (AC Input / DC Output) + Dimmer Functions (X6)
3. Socket (+Cover) (x6)
4. Socket terminal
5. 220V Power Cord (x6)
6. 220V Vintage Light Bulb_G125 Globe (x6)
7. 5V CDS Sensor Module (x1)
8. Touch Sensor Module (x1)
9. HC-SR04+ / Ultrasonic Sensor Module (x1)
10. Pull switch (x1)
11. USB Cable (x1)
SOFTWARE
- Arduino IDE
*** The Customized Module
We want to realize animation that controls brightness and speed of incandescent lamp(Vintage Light Bulb) according to ambient brightness. For this purpose, "The Customized Module" that converts the AC voltage supplied to the 220V incandescent lamp to a DC voltage is used. Also This makes it possible for incandescent lamp to be interlocked with Arduino.
Depending on the characteristics of the module, the B value of R, G, B is used for Brightness Control. A "255" value turns off the light bulb, and a "0" value makes the light bulb brighter.
Step 4: Measuring the Size
Measure the size of materials for accurate modeling.
The Measured Size (Width X Length X Height(mm))
● The Customized Module : 79 x 46 x 45 mm
● Arduino Uno R3 : 68 x 53 x 13 mm
● CDS Sensor Module : 40 x 14 mm (CDS Diameter : 3mm)
● Vintage Light Bulb : 125 x 125 x 170mm
● Socket : 44 x 44 x 55 mm
● Power Cord : Diameter 6mm
● The Outer Hole
The size of the outer hole is determined in consideration of the size of the materials.
- Neck section where socket is inserted : Diameter 60mm
- The hole through which the sensor is exposed : Diameter 5mm
- The hole where the power cord comes out : Diameter 6mm
Step 5: 3D Modeling & Making Output by 3D Printer ~
3D Modeling
1. Create a modeling file based on the measured size.
2. Convert the modeling file to an ".stl " file and upload it to the 3d printer.
Making output by 3D Printer
A body shaped like a person
3. Print it by 3d printer.
4. Sand the print by sandpaper. And combine the pieces of sanded print.
5. Use a putty to fill the gap.
6. Repeat the operation of the sandpaper and the surfacer until the surface of the print is smoothed.
7. When the above work is completed, finish with painting and clear (coating agent for abrasion resistant).

Step 7: 6 Types Coding
We want to realize animation that controls brightness and speed of incandescent lamp(Vintage Light Bulb) according to ambient brightness. For this purpose, "The Customized Module" that converts the AC voltage supplied to the 220V incandescent lamp to a DC voltage is used. Also This makes it possible for incandescent lamp to be interlocked with Arduino.
Depending on the characteristics of the module, the B value of R, G, B is used for Brightness Control. A "255" value turns off the light bulb, and a "0" value makes the light bulb brighter.

Step 8: Output
FRIEND'S LIGHT has a shape like a person. It consists of Black color body made with 3D printer and The head part replaced by the vintage light bulb.
This reflects life of the people who return from their exhausted lives, lights up a room, and contains a story that comforts and communicates someone. Through brightness of the surrounding space or human motion, sensor reacts and works by animating the light spontaneously. The Light Bulb can realize the light I want by the value set by Arduino coding.
In this way, we can experience the storytelling light reflecting the user's feelings and situations, and also has the function of interior lighting.
