I've made some progress with the project (albeit slowly). Right now I've managed to get some basic time and weather info being displayed on the LCD and web interface. Next step is to get the alarm system working plus implementing user-activated NTP sync.

A picture of the prototype, with the LCD attached. The time, date, humidity, and temperature are shown. A picture of the web interface, with time and weather data being separated into different panels, plus a non-functional section for controlling the USB ports. Currently, only the time, date, temperature, pressure, and humidity readouts work.

No, I'm not dead. Just busy.
Got the ESP32 to display and update the current time and date, as well as some info from the BME680, on an LCD with LVGL.
Next step is to get the web interface and NTP going again so that the time displayed can be remotely synced to network time.

Ok, so at this point I've pretty much finished with the layout of the first page of the web interface. I've made it fully responsive and fixed up all the formatting.

Time to move on to designing the actual user interface on the alarm clock's built-in display with LVGL. Stay tuned!
A picture of the final web interface at full size (with a bit off-screen). I decided to remove the 'sync' button because it's not really a primary function of the web interface and draws too much visual attention. A picture of the web interface with really narrow window width with all of the panels stacked vertically and with a single menu button instead of a larger navbar.

Ok, so I've managed to make some progress on making the web interface more size-responsive. I've gotten the panels to rearrange at 900px instead of 864px and altered how the panels rearrange to make it look better and be more space-efficient.

A picture of the prototype website with the width being less than 900px. The top time-related panels now rearrange in a slightly different way, and the weather-related panels in the middle are now divided into two columns in order for it to look better and be more space-efficient. Both of the top panel groups have dummy text to help me format stuff better. A picture of the website at full width. The humidity panel has had the formatting tweaked a bit, with text being centre-aligned and the humidity value being in larger font. This is so that I can figure out the proper minimum size for the smaller weather info panels, which will help me with managing how the website responds to size changes as I have a bit of a problem where the weather panels start to go offscreen from about 1776px to 1400px width.

FINALLY got the weather panels on my #esp32 alarm clock prototype web server page to stack when the width is less than 864px (there's also been a lot of other improvements since I last posted)!

A picture of the alarm clock web interface prototype in a browser at full width, with the time and weather function panel groups both at the top of the page above USB port controls. A picture of the same website but this time with a smaller screen width, and with the time function panel group above the weather panels, which are stacked on top of each other instead of in a grid like they were in the first picture.

Yesterday I finished programming my inital test program for the alarm clock project that allows the user to connect to WiFi, automatically update the RTC upon connection and output the time. As such, I'm going to start figuring out how I'm going to make the web server to control the clock.

A picture of my alarm clock prototype, consisting of an ESP32, DS3231 RTC and BME680 temperature, humidity, pressure and gas sensor. A picture of some of the code of the initial proof of concept program in VS Code, with the serial monitor open with the current date and time being sent across by the ESP32.

Ok, update time.
So a couple of days ago I acquired DS3231 and BME680 (I meant for it to be a BME280, but whatever) modules to help start prototyping my ESP32 alarm clock project. I've confirmed they work and I've started building the first proof-of-concept.
