Introduction: 千思万绪

This project is made by Zhenxuan and Bi, which we have named it as 千思万绪. This lamp was

designed for the couple who might not live together yet or long-distance relationships. They would have each have a light and the remote which could control each other’s light.

Sometimes in a relationship, you will be kept thinking what is he/she doing right now, did he/ she eat or some kind of questions around in your mind. Or when we don’t have something worth to discuss but we want to communicate with each other. That’s why this lamp came out to address these issues between the couples with the emotional lamp to tell your feeling to your partner. For instance, when you feel sad, annoyed or happy, but words is not enough to reflect how your feeling now or negative impact reflect on your love. For that moment, turning on the light is assisting you to send a silent message that you want her/ him to know you miss him/ her, need comfort or what are you doing to your partner.

The lamp would be separated two-part to different places because the switch will put it in your partner’s home. Therefore, each of them can control each light to tell their needs without direct language. Also, the would-be installed on the ceiling at each home and the remote would be portable so that people could carry it or put it everywhere at home.

Step 1: Prepare These Material to Build This Lamp

1.plastic ball line

3.glue gun

4.5v 4a switching power supply

5.arduino board

6.plastic tube

7.wire cutter

8.soldering wire


10.wood box

11.acrylic board

12.paper box

Step 2: Installation

Using a drill to make three holes in the opening of the plastic ball

Use the fishing line to go through the previous three holes, and adjust the length of the three fishing lines so that the ball can maintain balance when suspended in the air.

Prepare an acrylic board and laser cut a circle with a diameter of 6’’ and a of 3” cycles.

Correspond to the holes of the plastic ball and make three holes in the acrylic disc.

Cut a small piece of plastic tube and add glue as a fixed line.

Cut out different examples of three-section plastic tubes and put them on the led lights to hide the welded wires.

Next, drill a hole in the center of small cycle. The size of the hole depends on the size of all the wires tied to one.

When these basic entities are done, start writing code
