This project uses the CrowPanel 2.1-inch rotary display with an ESP32-S3 to create a small avionics simulator showing an artificial horizon, compass, and altimeter by combining I2C sensors and a custom graphical interface.

The RoadBook uses a Seeed XIAO ESP32S3 Plus and a 4.26-inch ePaper screen to guide you along pre-planned routes by counting down distances to waypoints, advancing automatically as you ride without turn-by-turn directions or distractions.

Connect your ESP32 over BLE to your browser and watch live updates from the BME280 sensor, thanks to Web Bluetooth’s JavaScript support.

Combine the open-source XiaoZhi AI with DFRobot’s ESP32-S3 AI Camera to create a voice-controlled assistant that sees, controls devices, and manages your calendar—all with real visual recognition.

Build an ESP32-based relay timer that uses the DS3231 for accurate time and stores settings in flash memory. It creates its own WiFi hotspot, allowing you to control the relay and program weekly timers through a mobile web dashboard without any external network.

The FCM365X from Quectel blends Wi-Fi 6 with Bluetooth LE, Zigbee, and Thread protocols, enabling seamless communication across diverse IoT devices. Its multi-protocol design simplifies building smart home or industrial networks that need reliable, low-power mesh connectivity.

Using a vacuum fluorescent display from an old calculator, this clock runs from USB 5 V with a single AA NiMH cell as backup, controlled by an ATmega328P and HV5812 chip. It includes features like multiplexed VFD driving, LDR-based brightness control, piezo feedback, and addressable RGB lighting while maintaining display stability during power changes.

This small solar power monitor uses an STM32 microcontroller and a custom PCB to track current and voltage from MPPT chargers, batteries, inverters, and auxiliary loads with four INA219 sensors, plus it handles inverter and auxiliary start control via UART communication.

A $200 mini PC using LattePanda with an Intel N150 and RP2040 microcontroller runs AI agents safely on a separate system, featuring a UPS battery, WiFi, status LEDs, and an OLED display that shows real-time AI states.

By connecting your ESP32 to Microsoft Azure IoT Hub, you can build a secure pipeline to send data from your edge device to the cloud, enabling live dashboards and alerting through other cloud services.

Combining medical-grade sensors and a microcontroller, AegiWatch delivers instant readings of heart rate, oxygen levels, and 6-axis movement, all controlled via a push button and shown on a compact OLED display.

These QuickKeys use ESP32s to send button presses over WiFi and serial, lighting up OLED animations and syncing with each other while a Python listener runs personalised meme scripts or anything else triggered.

This project combines an ESP32-C6, a GNSS module, and a BMM350 magnetometer to create a compact handheld device that shows real-time distance and direction to a set waypoint, even when standing still, with about ±5 meters accuracy.

This custom keypad uses an ESP32-C6 chip with Zigbee, an MPR121 capacitive touch controller, and printed number labels on the PCB, all packed into a neat 3D-printed case and powered by a 1300 mAh battery that lasts six months.

Breaking the 1 nm barrier, IBM’s 0.7 nm chip integrates close to 100 billion transistors with a novel transistor architecture and 3D nanostack. This leap in semiconductor tech offers up to 50% faster speeds or 70% less power use, advancing computing and AI applications.
