*Problem:* Taking bath could be one of the most soothing times of the day. Many people enjoy playing music while taking a bath. However, it becomes very inconvenient and even dangerous when we want to skip to the next song in the middle of the shower: using wet finger on a touch screen could damage the phone and even cause electricity accident. Therefore, we need to find a way to interact with the playlist without any physical contact. Furthermore, it would be even better if ambient lights are added for creating a more immersive, joyful shower experience, and temperature and moisture information could be also added to give user a better understanding of the current environment.

*Solution Intention:* To solve the problem, we could implement an interactive system that integrates all of the features mentioned above: playing music, illuminating ambient lighting, displaying temperature and moisture information, and being able to change songs and lighting with gesture (without any physical contact, which is the main idea of this project.) We plan to make this a portable device so the user could bring his or her favorite bathroom interactive system to any bathroom in the world. Indeed, the usage of this device is not limited to bathroom only. In addition to solving the crucial problem of the inconvenience and danger of phone usage during shower, this device makes our lives easier, more enjoyable, and provide information about the environment at any given circumstance.

*Solution Components:*

* Software Component:
* Music: Music is played from the user’s phone to the speaker using Bluetooth connection. Flipping hand up/down would go to the next/previous song in the playlist.
* Lighting: The color ambient lighting would change as the user flip his or her hand left/right.
* Hardware Component:
* HAND GESTURE RECOGNITION (HGR)
* Multiple infrared sensors are deployed to detect the movement of user’s hands. These data are gathered together using a micro-controller connected to solve for the trajectory of hands movement. Then the board will analyze the result and match a certain light mode or skip to another music in the list. The measured results will broadcast through LCD screen. Although the result can be collected by microcontroller, it should be general enough for other systems to easily utilize the data.
* INTERACTIVE SYSTEM
* Interactive light (intentionally WS2812b): This module allows programmable light control to interact with captured gestures and played music beats. The light cell will change the amplitude and frequency with beats profile adjusted. Apart from that, when we enter special mode or encounter unexpected events, they can give some feedback on our controller.
* Bluetooth module: The Bluetooth module transfers data from music playlists in mobile, and fetch data from
* Temperature sensor: This module allows we collect the room temperature and display on the LCD.
* Display: Majorly, the LCD screen serves as a display, indicating the humidity, temperature, and music playlist. The controlled by 4 bit dribbles signal from microcontroller, with the function of scrolling marquee and delayed input.

*Features:* The features of this device include a distance and gesture sensor, a speaker, an LCD screen for display, and lighting.
Expected look of the device:

*Criterion for Success:* The catching point for this project is contactless, enjoyment, and portable. There are some products on the market that has similar ideas as ours but none has the exact same feature and functionalities as ours.

This device is placed on top of the shower head and is able to play music and emit lighting while taking a shower.

--: This device is not contactless, no gesture recognition, and it doesn’t provide any information about temperature and moisture.

Lighted Mirror from Kohler:

This product is used as the mirror in the bathroom and is able to work with Alexa to play music and get environment information

--: This product is not portable. It has to be used at a specific bathroom. This product is not contactless/no gesture recognition. And it doesn’t have the ambient lighting (white light only).
We believe in the success of this device because:
1. Being able to change music/lighting without physical contact is enjoyable and safe during shower.
2. This device makes our lives easier and it is portable to bring to anywhere.
3. There is no existing product on the market that has the exact same features

RFI Detector

Featured Project

Problem Statement:

Radio frequency interference from cell phones disrupts measurements at the radio observatory in Arecibo, Puerto Rico. Many visitors do not comply when asked to turn their phones off or put them in airplane mode.

Description:

We are planning to design a handheld device that will be able to detect radio frequency interference from cell phones from approximately one meter away. This will allow someone to determine if a phone has been turned off or is in airplane mode.

The device will feature an RF front end consisting of antennas, filters, and matching networks. Multiple receiver chains may be used for different bands if necessary. They will feed into a detection circuit that will determine if the power within a given band is above a certain threshold. This information will be sent to a microcontroller that will provide visual/audible user feedback.
