Talk:Quest: Bubble TV
Overview:
In this quest, you'll explore how sound underwater, like bubble noises, can be turned into a colorful light display. You will learn how to use special underwater microphones to capture the sound and then turn it into a light show, just like how white light is made up of many different colors. This project combines science, technology, and creativity! Week 1: Learn About Underwater Sound and Microphones
Objective: Understand underwater sound and how microphones can capture it.
Activities: Explore how sound travels underwater and how bubbles make noise. Learn about special microphones (called hydrophones) that work underwater. Discover how sound can be broken into different parts (frequencies), just like how white light is made of many colors. Try out some basic microphone examples and see how they pick up sound. Project Milestone: Draw a plan for where you would place the microphones in the water to capture bubble noises. Think about how the microphones will listen to the sound.
Week 2: Sound Analysis and Fourier Transforms
Objective: Learn how to break sound into its different parts and study its patterns.
Activities: Learn about how to look at sound in different parts or frequencies using something called a Fourier transform. Listen to samples of bubble noise and try to see what frequencies are in the sound. Use simple programs (like Audacity or a free app) to view the frequencies in bubble sounds. Project Milestone: Take a sample of bubble noise and show the different frequencies in the sound using a program. Create a picture or graph of these frequencies.
Week 3: Turning Sound Into Light
Objective: Design a way to turn the sound of bubbles into colorful lights.
Activities: Learn about how light works and how colors are made from different light frequencies (just like how different sounds have different frequencies). Discover how LED lights or projectors can change color depending on what frequency they are told to display. Plan how to connect the frequencies of the bubble noise to the colors of the lights. For example, higher frequencies could be a bright color, and lower ones could be darker colors. Project Milestone: Build a simple display using lights (LEDs or a projector) and experiment with making the lights change based on different sounds or frequencies.
Week 4: Putting It All Together – Microphones and Real-Time Processing
Objective: Set up a system to capture the bubble sound and control the lights with it in real-time.
Activities: Learn how to connect the microphones to a computer or a small controller like a Raspberry Pi or Arduino. Set up a system that listens to the sound, breaks it down into frequencies, and then uses that information to control the lights. Try it out with some bubble sounds and see how well the lights react. Project Milestone: Test your system with the microphone, sound processing, and lights all working together. Make sure the lights change based on the sounds you hear.
Week 5: Making It Interactive and Fun
Objective: Add some interactive elements so the display reacts to changes in the environment.
Activities: Test the system in different underwater environments, like with more or fewer bubbles. Experiment with how the display reacts when the bubble noise changes, like when a diver moves or when marine life is nearby. Add extra features to the display, like making the lights blink or change patterns when the bubble noise gets louder. Project Milestone: Finalize your interactive display, making sure the lights change in fun and creative ways based on the bubble noises.
Week 6: Final Presentation and Reflection
Objective: Show off your project and reflect on what you've learned.
Activities: Prepare a presentation to explain how your microphone array works, how you processed the sound, and how the display changes based on the bubbles. Reflect on what was fun and challenging about the project and how you could improve it. Share your project with classmates and explain how the sound of the bubbles became a beautiful light display.
Project Milestone: Present your final project to the class, showing how your microphone array and light display work together to turn bubble noise into a colorful light show. Share your thoughts on the science behind the project and how you solved any problems.
Choice Elements:
Throughout the project, you can choose how you want to build your system. You can decide what tools to use for sound processing (software or apps), what kind of lights to use (LEDs or projectors), and which microphone setup to use. You can also pick different types of bubble noises to work with, like those made by marine animals or divers! Assessment:
Final Presentation: Show your completed project and explain how everything works, from capturing the sound to making the lights change. Reflection: Write or discuss what you learned about how sound and light are connected, and how you turned sound into light in a creative way.

For this project, you'll need specialized hardware to capture the underwater bubble sound, process the data, and create a visual display. Here’s a breakdown of the hardware that could be used for each part of the system: 1. Underwater Microphone Array (Hydrophones)
Hydrophones: You need high-quality underwater microphones to pick up the bubble sounds. Example: Aquarian Audio H2a-XLR Hydrophone A widely-used hydrophone that works well for general underwater audio collection, capturing frequencies from low to high. Example: Ocean Sonics icListen Hydrophone A more professional-grade hydrophone with a higher sensitivity for detecting underwater sound, including bubble noise.
Microphone Array Setup: For a good resolution, use a hydrophone array (a series of microphones placed in different positions). Example: Microphone Array Kits (such as 12 or 16-channel arrays used in marine research) could be built or purchased. These kits typically come with multiple hydrophones that can be placed in a fixed pattern (e.g., circular or linear) to capture a broad range of sound.
2. Microcontroller for Data Processing
Raspberry Pi 4 or Arduino (depending on complexity and real-time processing needs). Raspberry Pi 4: Good for more complex tasks like real-time data processing and controlling the light display. Arduino Nano or Mega: If the sound processing can be offloaded to a computer, an Arduino can be used to control the lights and display based on input from the microphones.
3. Sound Processing and Frequency Analysis
Software/Platform: Python with libraries such as NumPy, SciPy, and PyAudio for capturing and analyzing sound data. The Fast Fourier Transform (FFT) algorithm can be used to break down the bubble noise into its frequency components. MATLAB: A more advanced option for analyzing sound and visualizing frequency spectrums. Sound Interface: USB Sound Card: To connect your hydrophones to a computer or Raspberry Pi. Choose one with multiple channels to match the number of microphones in your array. Example: Behringer UMC404HD – A 4-input USB audio interface that works well for handling multiple hydrophones.
4. Visual Display Hardware
LED Lights: Use RGB LEDs that can change colors based on the frequencies. Example: WS2812B RGB LED Strip (also known as NeoPixel) – These are programmable and can be controlled individually for color-changing effects based on frequency inputs. LED Matrix or LED Panels: If you want to create a larger display. Example: Adafruit NeoMatrix – A matrix of individually controlled RGB LEDs that can form patterns.
Projector (optional, for more advanced visual displays): Use a small HDMI projector to project patterns or graphics based on frequency data. Example: ViewSonic M1 Mini Plus – A portable projector that can display patterns or colors on a screen or wall.
5. Signal Processing Hardware
Digital Signal Processor (DSP): If you want to offload the processing work to a dedicated hardware unit for real-time performance, you can use a DSP. A TI C2000 DSP could be used for sound analysis. Example: ADI SHARC DSP – Another powerful signal processor that can handle real-time FFT analysis.
Analog to Digital Converter (ADC): If you're using analog microphones, you’ll need an ADC to convert the sound into digital data for processing. Example: Texas Instruments ADS1115 – A simple, 4-channel ADC that interfaces with a Raspberry Pi or Arduino.
6. Power Supply
Battery or Solar Panel (for outdoor or underwater setups): Example: 12V Li-ion Battery Pack – A rechargeable battery to power your microphones and Raspberry Pi. Solar Panel: If the project is outdoors, a small solar panel can be used to keep the system running, especially in remote areas.
7. Cables and Connectors
Waterproof Cables and Connectors: Use waterproof cables and underwater connectors to ensure the system works without any water damage. Example: SubConn Underwater Connectors – Known for being durable in wet environments. Coaxial or twisted pair cables for transmitting signals from the hydrophones to the data processor.
Suggested System Layout:
Hydrophones: Set up in a grid or circle to cover the area where you want to capture bubble sounds. Raspberry Pi or Arduino: Connect it to the microphones (via a USB sound interface or ADC) to process the sound data. LED Strips or Projector: Use this to display visual patterns based on the frequencies detected by the microphones. Power Supply: Ensure all components have a stable power source, either from a battery or solar power, depending on the project setup.
