How to make a shiny crown? | DF LAB: Inventor Series EP08
In this workshop, students will design and make a shiny crown. Different from a normal birthday crown, this crown will start blinking when you jump up and down or shake your head side to side.
Difficulty Level: 1
Number of Participants: 1~24
● Prepare a name label for each student in case they don’t know each other
● Arrange tables and chairs in U-shape for each team
● Put tools and other materials in two specified places of the room
● Design and make a shiny crown
● Learn to build up a circuit with BOSON
● Use digital media tools to shoot video clips
● BOSON Inventor Kit V1.0 (Refer to introduction for more details)
● Paper Model (See appendix)
● Colored Paper
● Colored Pen
● Camera or Smart Phone
Award and Evaluation Criteria
Students should be informed of the award and evaluation criteria. Special awards will be given to individuals or teams who perform well in the competition.

5min Dismantle projects and clean up
5min Projects review
Warm-up (5min): teachers ask some questions about birthday to broaden students’ horizon.
● Do you know why people get to celebrate birthday every year? What are the origins and traditions of birthday celebration?
● Why do we wear paper crowns on birthday?
a. What is BOSON?
b. Project interaction display
c. Get to know modules and learn how to connect
What is BOSON?
Teachers play the video below to show students what BOSON is？
Project interaction present
● Teachers demonstrate the project interaction effect using material objects.
● Present the project effect by playing video
BOSON module function and connection
Teachers tell students the module name and similar applications in daily life.
The shiny crown needs power from the main-board and power source.
How do we control the lights on the crown? Use tilt sensor, the internal small steel ball will connect the circuit when it tilts. It is a sensor.
Then shiny crown can shine with beautiful decorative light.
Use the multicolor string light, it is an actuator.
Have you noticed the color of these BOSON modules? Red is for power supply, blue for sensor, and green for actuator. How to connect them correctly?
Place the blue sensor on the left side of the power board, and the green actuator on the right side.
Start Making (10min~20min):
Analyze (how to realize functions and connect hardware) and check; cut paper; assemble.
Test whether the project structure is firm and all the modules are tightly clamped.
Test whether the shiny crown works as expected.
Use colored pen or paper to beautify the appearance of the project.
a. Shoot a video for the project, and post it to social account.
● Project display
● Effect demonstration
● Group photo
b. Present and introduce the project on stage
● Introduce the basic function of the project
● What improvements have you made? And why do you do that?
● What’s the highlight of your project?
Assess students’ works according to the Evaluation Criteria(see appendix) and select the best one.
Clean up (5min)
● Dismantle the BOSON module on the project
● Put all modules back to the BOSON box.
● Put Inventor Kit and Tools to the specified place.
● Clean up the litters on the table and ground.
● Why does our birthday crown shine?
● What else do you think the tilt sensor can do? How about making a Whac-A-Mole game with it?
Here are some factors that should be taken into account when designing this workshop, and teachers can adjust, add or cancel some unimportant parts of the process as actual conditions.
● Age: adjust the requirement of skill and knowledge according to students’ age and cognitive ability.
● Time: 50 minutes or more.
● Number of Students: control the number of students and choose to carry out a project in the form of individuals or groups as the actual scene.
Paper Model: the figure below can be printed as a paper model.
Evaluation Criteria: teachers can observe students in the whole process to evaluate their performance.
