Diagram

Initializes parts of code; sets variables to initial value of 0 etc;

_init_ ()

Reads all data from serial port from arduino + separates individual values (each one= self.display_number) & passes each value through self.update_display function; only works if self.stop_button_clicked is set to False

read_serial_port ()

​

​

Displays new text on textEdit:

self.textEdit.setText (text_to_update)

​

update_text_edit ()

Calls self.player.play function (built in function from player)

play_video ()

Connects certain user actions (ex: clicking buttons, drop-down selections) to specific functions; ex: connects StartButton to self.on_start_click, so if clicked, function called

connect_actions ()

Sets a resting heart rate value for variable “self.restinghr” based on what user selects, or displays on textEdit to select an age

dropdownselectionhr ()

Sets a resting heart rate value for variable “self.restinghr” based on age range that user selects

dropdownselectionage ()

Displays “--” on HRDisplay if waiting for data

Displays data passed through the function on HRDisplay

update_display ()

Sets self.stop_button_clicked to True (which won’t allow read_serial_port to work)

on_stop_click ()

Sets self.stop_button_clicked to False + sets textEdit to display “Monitor Running”+ starts serial_port thread

on_start_click ()

. Finds difference of self.display_number & self.restinghr; diff

. Updates textEdit based on what diff is + sets self.file to be specific video→ video is displayed if diff is big enough

stress_level ()

Calls self.player.pause function (built in function from player)

pause_video ()

Laptop

The Tech Museum

Challenges:

• Learning to use a new tool (SketchUp) to make 3D models. First time doing 3D modeling
• Making and fixing the circuits for the house (mainly the sound circuit)
• Putting the 3D pieces together

My MAGICal Experience

My Project

​

• My project name is Mini House with circuits
• In this 3D printed house I have included a LED light and a motor fan. I designed the 3D house and made both the circuits.
• I chose this project because I liked hardware electronics and it would also be a cool twist to a normal toy house

​

Future improvements

​

• Add a sound circuit like a doorbell
• Make rooms in the house and move fan to a room

​

​

My Project

• In order for me to make this I first had to come up with how I wanted to build this
• Once I came up with an idea me and my mentor prototyped in several different ways
• We then built the house out of 3D printed parts

We Finished!

​

Things I Learned

• Basics of electronics
• What are electrons?
• What is resistors, voltage?
• Snap Circuits
• What is a breadboard? How to make different kinds of circuits on breadboards
• How to debug circuits
• CAD/3D Modeling
• How to use the tool SketchUp
• How to make parts, assemblies
• Prototyping
• Using legos, cardboard, tape to mock up the house before 3D printing it

​

​

​

Snap Circuits

Snap Circuits is a electronics kit for kids to learn about some basic circuits and how to make the different circuits.

​

• The basics of what I learned using this is what a circuit is and what is inside a circuit
• I used the snap circuits to prototype my circuits needed for my final project

​

​

​

​

Sketchup

• SketchUp is a tool used to create 3D models
• I used this for prototyping and for making the final model
• While using this tool, I had to watch videos/tutorials on how to do something
• From this I learned how to make models and that you can use SketchUp for many things

​

​

​

My Demo

The Prototype of the mini house:

​

This was used with Legos and Snap Circuits. The Snap Circuits were used to make a prototype version of the circuits of the sound(doorbell) and a light.

First half of the year

What is an Exoplanet?

• An exoplanet is a planet that orbits a star outside our system

My Project: What is an Exoplanet Transit?

• Dimming of light as an exoplanet passes in front of its host star and casts its shadow on our telescopes
• The graph shown is called a “light curve”
• Dip is the “transit”
• To find planet’s radius:

​

The Discovering Exoplanets Program

• Graph from data that you input
• Tells you size of your exoplanet
• Allows you to zoom in at the dip from your graph
• A program that is able to calculate the size of an exoplanet based on the information that you give
• Program can process data you give and give you the size of your exoplanet

The Discovering Exoplanets Program

• A light curve created from the Exoplanet program

Stargazing on a New Level:

Final project

Last half of the year

What is a star?

• A ball of hydrogen and helium
• It shines by fusion

The Sun!

Types of Stars

• Different types of stars

The Hertzsprung-Russell Diagram

• Temperature and luminosity of stars and type
• Can tell what type of star you have if you make a Hertzsprung-Russell Diagram

My Project: Making a Hertzsprung Russell Diagram

• Identifying where the stars are in a globular cluster
• Observed with the Hubble Space Telescope
• Making a table with all the values of brightness and location
• Taking the points from above and plotting them onto a graph
• Identifying what type of star each is from the graph
• Adding color
• The Diagram is made!

The Raw Data

• Red and blue filter data
• x-coordinate and y-coordinate
• Flux is “brightness”

Create an Image of the Data

• Use Python tool astropy and SEP
• Combine red, blue and green light
• Use Matplotlib imshow to make plots
• Add color to the picture

Identifying where the Stars Are

• Used program looked for objects brighter than the average brightness of the entire picture
• Change the brightness threshold number high, you will find less stars
• Set a radius of the circle around the star
• The program sums all of the pixels in circle to make flux

The Table (2) Data

• Red and blue filter data & star brightness
• Location & brightness of stars circled

Hertzsprung-Russell Diagram

1. Matplotlib used to make plot
2. OIB (Objects in both) is defined
3. magR is defined
4. Masks for only signifying certain part of plot
1. Hertzsprung-Russell Diagram shows there are lots of Main Sequence Stars
