Weather Crow is an ESP32-S3 based weather station featuring an E-paper display that shows current weather conditions and forecasts. This initial release provides a complete solution for monitoring local weather with minimal power consumption through efficient deep sleep cycles. the project is under the MIT license, so you can modify or chage as you want!!

Project #15: Environment – SD – Mk28

A compact and visually engaging timer app using an Elecrow 1.28-inch round display and LVGL. Start the countdown with a button, track progress with an arc widget, and handle I2C input for extended control. Ideal for Arduino projects requiring an interactive timer with touch functionality and hardware integration. ????

This is a relatively simple, visually effective balancing robot project that only requires four components to make.

I started providing LoRaWAN coverage in my city by mounting the ThinkNode G1 gateway to my attic and I made a portable device to test out the reach that it has.

H2S-Dev board is a ready-to-use, Open source hardware, Arduino compatible, LoRaWAN Helium network sensor development board. It is capable of implementing a number of sensor (Basic and Full variant) and positioning applications (Full variant only). The board is mainly targeted to makers and hobbyists.

This project is about monitoring temperature and humidity with CrowPanel 3.5 Inch, DHT11 Sensor, Arduino IDE, LVGL and EEZ Studio.

The device presented in this project uses an Elecrow E-Paper display module with a built-in ESP32S microcontroller and additional components enclosed into a suitable housing, and requires almost no hardware intervention, so we only need to install the sketch and get a fully functional final product.

The ESP32-BlueJammer (Bluetooth jammer, BLE jammer, WiFi jammer, RC jammer) disrupts various devices using an ESP32 and nRF24 modules, causing plenty of noise and sending unnecessary packets (DoS). It interrupts: The whole 2.4GHz broadband! Everything that works on 2.4GHz is being interfered, like: audio in speakers being transmitted over bluetooth, microphones on 2.4GHz, smartphone connections, WiFi, RC Drones (etc.), IoT devices, smart gadgets, wireless keyboard & mouse, just anything on 2.4GHz! Ideal for controlled disruption and security testing. Based on 2,4GHz communication. It has a big range (over 30Meters+ - may vary on your antenna and hardware setup!) on newest Bluetooth versions with casual 2.4GHz antennas, you can easily increase this aswell by taking some simple "bigger" router antennas. An amplifier (2.4GHz) may be an good option too! Remember that jamming is illegal and should not be used with malicious intent! This is strictly for educational purposes only!

This project guides you through designing, 3D printing, assembling, and finishing a custom Bluetooth speaker with a wood-like finish and great sound quality.
