Project Description:
With social development, technological progress, economic development, and economic expansion, the rapid advancement of modern electronic, communication, and computer technologies has led to an increase in the phenomenon of "sycophants" (or "sycophants"). This reflects a decline in trust and amplified loneliness in society, a natural human reaction for survival. This project combines embedded technology with the concept of "sycophancy" to design a "sycophant pendant" that reminds users to drink more hot water, etc., to improve the efficiency of sycophancy and provide a home for every sycophant.

Project Functionality: The project
will remind others to drink more hot water based on different temperatures and humidity levels.
Project Attributes:
This is the first public release of this project, and it is my original work. This project has not won any awards in other competitions.
 
Project Progress:
2024-01-01: PCB design completed, but not yet tested on a board.
2024-02-01: Soldering and debugging. The hardware
design
aims to be portable. First, it needs a battery, using a TP4056 for charging and a DC-DC chip for voltage regulation to power the ESP8266. It includes 2-3 buttons for changing cities, as many devices don't support this feature.
The software
uses the ESP8266 as the control core and is written in Python. First, the Python firmware is flashed, then the ESP8266 is developed using Python. It connects to a personal hotspot, retrieves weather information, and reminds users to drink more water based on temperature and humidity levels. The first two photos
show
 
a 3D view of the PCB and a picture of the PCB soldering. The third photo shows the device connected to the personal hotspot after flashing the first firmware. The fourth and fifth photos show the screen displaying weather, wind direction, and reminders to drink water after flashing the second firmware and connecting to Wi-Fi. Pressing the two bottom buttons changes the city; the number of cities increases or decreases, and the information is updated when the first page is refreshed. Pressing the first button resets the settings.
Design Considerations:
First, you need to flash the Python firmware onto the ESP8266. Then, use uPyCraft.exe to open the two files and flash one of the firmware files first. Set your personal hotspot or other Wi-Fi network to the username "WIFI123" and password "12345678". The device will then connect to your Wi-Fi. Next, flash the second firmware. After a short while, the screen will refresh.
