Unexpectedly, the latest rock universe (SOLIDROCK UNIVERSE) facilities are here!

This is the sudden conquest of the difficult ST7789V2 TFT screen after the toss out of things ~!

I call him Desktop Health Station!

• Dicing Into the Rock Universe | Peak Power
• science fiction is retro and has a little military terminal style.
• It's easy to print (just use PETG)
• the support removal of the main body is a bit time-consuming, but it is definitely worth it.
• The main functions are as follows:
  • clock mode:
    • boot default mode
    • can display the current time and date (you may ask, where did the time and date come from? Good, keep reading)
    • automatic timing (the current version performs time calibration by connecting to known WIFI every hour; Forced calibration when powered on for the first time) and never deviates.
    • The whole point reminder

    • NTP automatic timing setting method (important): in clock mode, press and hold the touch switch for more than 5 seconds, and the following screen will be entered:

      

      this means that you have entered the WIFI setting mode. when the mobile phone turns on WIFI, you will find a WIFI STATION by S.R.U HEALTH. just connect him directly. the password is 12345678,

      after the connection, there will be a page for you to enter the WIFI account number and password of the current environment. After entering, click Finish and you are done!

  • Health Station Mode:
    • automatic switching by touching the MAX30102 heart rate/blood oxygen module in the small hole on the right
    • hold your finger for about 8 seconds to display the current stable heart rate/blood oxygen value (due to non-professional medical equipment, the results are for reference only)
    • due to the different skin color and skin thickness of each person's fingers, it is sometimes difficult to measure. But! You can press the touch switch to enter the dynamic baseline calibration mode, that is, according to each person's different physical conditions to establish different measurement thresholds! After you need to enter the dynamic baseline calibration, keep your finger touch the sensor until the progress bar is full, and your dynamic baseline will be saved successfully!
• Non-printing bill of materials:
  • ESP32-C3 Development Board
  • 2.0 inch ST7789V2 TFT screen (240*320 resolution)
  • MAX30102 heart rate blood oxygen module
  • 12*12*3.8 touch switch
  • PCF8563 the RTC clock module ( no need to buy batteries! No need to buy batteries! No need to buy batteries! Because every time I power on, he will immediately calibrate the current time!)
  • duPont Line Mother to Mother Several
  • any charging head
  • USB TYPE-C charging cable
• see Document 1-Code Section for program code
• see document 2-Wiring Scheme for wiring method
• brief assembly instructions are as follows:
