IV-18 VFD Clock

ESP32 driven IV-18 VFD desktop clock

I'd been eyeing the IV-18 transistor for a long time, and after browsing LCSC's open-source projects, I couldn't find a design that perfectly suited my needs. So, I decided to make one myself.
The hardware and software are largely based on @AmamiyaYukoDesu's design. The ESP32 still has many pins left, allowing me to modify the schematic to add features like a buzzer, temperature and humidity control.
The
RTC uses an RX8025T, the VFD driver is an HV5812, and it incorporates a TEMT6000 ambient light. Considering I'm too lazy to constantly charge a clock, I opted for wired power instead of a lithium battery. The micro-USB port provides power and allows for programming, while the Type-C port only provides power. This design offers flexibility in power supply, and the Type-C port only requires 6 pins, making soldering easier.
I used a two-layer stacked board design, connected by header pins in the middle. The two boards on the left are left unsoldered for aesthetic symmetry. The four boards are connected by four M3*160 threaded rods and secured with several M3 nuts.
The program
is written in Arduino, and the main framework uses FreeRTOS.
Currently, the button display shows the date for two seconds with a short press of the KEY key; a long press of the KEY key enters the time/date setting mode, where a short press of the KEY key selects the currently set digit, and short presses of the UP/DOWN keys adjust the value of the current digit. The current version may contain a few bugs.
Solutions to potential problems: 1. Check if the Onebutton and RX8025 libraries are installed. 2. If the digital tube display is incorrect, try jumping to the definition of RX8025_init() and modifying the I2C pin to: Wire.begin(22,23);
ESP32 can also achieve network-synchronized clock and IoT control effects. I may continue to update the program in the future if I feel like it.

Smart sensor desk lamp

It is equipped with a photosensitive sensor and an ultrasonic sensor to detect the ambient light intensity and the distance between the person and the desk lamp. At the same time, the indicator light and the LED screen receive the output signal of the microcontroller. The indicator light is used to simulate the desk lamp in the target, and the LED screen is used to display the distance between the person and the sensor.

Design Scheme: The digital display photosensitive eye-protection LED light is powered by a 220V AC power supply, which is converted to 5V DC power by a power module to supply power to the GD32 microcontroller. The microcontroller controls the entire circuit. First, the ultrasonic sensor detects a person approaching and automatically turns on the circuit; if the person leaves, it automatically turns off. When the circuit is on, the photosensitive sensor detects the ambient light brightness and transmits the signal to the microcontroller. The microcontroller uses the signal returned from the photosensitive sensor to change the magnitude of the signal sent to the LED lights (such as the duty cycle of the PWM wave) and displays the brightness level through four LEDs. The signal sent by the microcontroller to the LED lights is then directly supplied to the LED lights through a dimming circuit and an amplification circuit, causing them to turn on and off.
