Final project
you can find the full documentation for my final project by pressing the button
I have three idea and during the fab journey I will chose one ,
My first idea is an alarm ring help you to wake up early by using water spray and vibration device to force you wake up exactly when your phone alarm ring .
My second idea is about a problem that face some people when they walk generally their leg land on floor with an angle and you can notice that by looking for the deformation of their chose that it be so damage from side and the other side don’t have a very little damage so what I think is to but like a device inside their shoes to alert them when they walk in that way and try help them to correctly move their legs on floor .
My third idea is a submarine that move under water to take alive stream for sea and the environment under water and make that stream available for all people to watch it and figure out the beauty of the sea also I can put like a gripper to collect the trach under the water and help the environment to reduce the pollution of the sea .
And this is a simple sketch for the ideas ==>
new project idea key founder
The idea came to me while I was on a weekend and needed to use my car. I struggled to find my car key and searched everywhere in my home, which took a lot of time. After giving up on finding the key, I put my hand in my pocket and found that I had put it there. That's when I thought of creating a device that would produce a sound and be connected to my key, so I wouldn't have to go through the hassle of searching for it again.
Idea Specification
- The idea is to create a system consisting of two components: a remote that can be worn and a device that can be attached to a key.
- The remote will be used to send a signal to the device attached to the key to make a sound.
- The system will use Bluetooth Low Energy (BLE) to establish a connection between the two components.
- The purpose of the system is to help users quickly locate their keys when they are lost.
Application and Implication
What will it do?
The key finder medal will help people locate their keys. It consists of a remote and a target. When the user presses a button on the remote, it sends a signal to the target. The target, when activated, emits a beeping sound and activates a light, making it easier to find the keys.
Who's done what beforehand?
Similar products, such as iTags and other key finders, already exist in the market. These products utilize Bluetooth technology to establish a connection between a remote and a target to locate lost items.
What will you design?
You will design a key finder medal that includes a remote and a target. The remote will have a push button and an XIO ESP32C microcontroller. The remote will also be redesigned to be wearable on the hand for convenient usage. The target will have a buzzer, a light, a light sensor, and an XIO ESP32C microcontroller.
What materials and components will be used?
Materials:
- PCB board for remote (made with PCB fabrication using a PCB design software)
- Flexible and smooth TPU material for the target
- PLA material for the redesigned wearable remote
Components:
- XIO ESP32C microcontroller for both remote and target
- Push button for the remote
- Buzzer for the target
- Light module for the target
- Light sensor for the target
- Bluetooth Low Energy (BLE) module for communication
- Passive components (resistors, capacitors, etc.) for circuitry
- Rechargeable lithium battery (3.7V) for power
- Switch for on/off functionality on the remote
Where will they come from?
The materials and components can be sourced from electronic component suppliers, online retailers, or local electronics stores.
How much will they cost?
The cost of the materials and components will vary depending on the specific brands, quantities, and suppliers chosen. It is recommended to research and gather price estimates from different sources to determine the overall cost.
What parts and systems will be made?
The parts that will be made include:
- PCB board for the remote, which will be designed using PCB design software and manufactured using PCB fabrication methods.
What processes will be used?
The processes involved in the project may include:
- Designing the remote and target using CAD software
- Designing the PCB layout using PCB design software
- PCB fabrication for the remote
- Soldering and assembly of electronic components onto the PCB
- Programming the microcontrollers for both remote and target
- Testing and troubleshooting the functionality of the key finder system
What questions need to be answered?
Some questions that need to be answered during the project may include:
- How to optimize power consumption for extended battery life?
- How to ensure reliable and secure communication between the remote and target?
- How to design an intuitive user interface for the remote?
- How to calibrate the light sensor for accurate detection?
- How to optimize sound come from target inclosure ?
How will it be evaluated?
The key finder medal can be evaluated based on its effectiveness in locating keys, the reliability of the Bluetooth communication, the responsiveness of the remote button, the convenience and wearability of the redesigned remote, and the overall user experience. User feedback and testing can be used to assess the performance and usability of the key finder medal.
