Mini Smart TV – Weather, Clock & Mood Display

This Mini Smart TV is a compact 3D-printed ESP32 desk display designed to combine useful information with a fun animated interface. The project uses a small 0.96-inch OLED display mounted inside a TV-style upper housing, while the ESP32 board, battery, charging module, power electronics, and wiring are placed inside the lower base.

The display can show useful information such as the current time, date, temperature, humidity, and weather conditions using data from the OpenWeather API. It can also display different animated mood faces, giving the project a more interactive and character-like appearance.

A TTP223 capacitive touch sensor is used to control the display without needing a mechanical push button. A short touch can be used to move between the different display pages, while holding the touch sensor for around 2 seconds changes the mood expression. Holding it for approximately 5 seconds can be used to enter the Wi-Fi and API configuration mode.

The Wi-Fi name, Wi-Fi password, OpenWeather API key, city, and other settings can be entered through a local ESP32 configuration page. Once the settings are saved, they are stored in the ESP32 memory, so they remain available even after the device is switched off or the battery is disconnected. When the device is powered on again, it can automatically reconnect using the previously saved settings.

The enclosure was designed to be easy to 3D print and assemble. The electronics are separated into two main sections: the OLED display is located inside the upper TV-style housing, while the ESP32 and power system are protected inside the larger base. Wires between the display and the ESP32 can be routed internally through the support between the two sections.

The project can be powered using a 3.7V lithium-ion battery together with a charging and 5V boost module. An ON/OFF switch can also be added to the enclosure for convenient power control.
