Project #15: Environment – SD – Mk28

Ever wondered how to combine technology and simplicity in your workspace? This is all about how to build an IoT Weather Clock using the CrowPanel 4.2-inch E-Paper Display—a sleek, power-efficient display powered by the ESP32-S3!

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.

Project #25 - Movement - SD - Mk12

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.

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

Project #15: Environment – GPS – Mk27

Introducing a cost-effective flight controller PCB designed for budget-conscious drone enthusiasts and educators: powered by the STM32F405RGT6, this board integrates the MPU6050 IMU and BMP280 barometer for stable flight in basic quadcopters and fixed-wing UAVs, offering a reliable, easy-to-integrate solution perfect for learning and experimentation, with open-source compatibility and simplified design.

This is a simple visually interesting toy for describing fluid dynamics.

The Elecrow Pico W5 is a board based on Raspberry's RP2350, featuring unique characteristics that set it apart.

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!
