The future of air transport

Identify noxious air bubbles lurking in the substrate w/ ultrasonic scans and assess water pollution based on chemical tests simultaneously.

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!!

A Short PCB tutorial so you can make your first PCB.

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!

Mentor Mitra AI is a smart educational toy with a custom ATmega328P PCB that integrates the AI Thinker VC02 chip,temperature sensing, interactive voice features, and a web dashboard for personalized learning insights.

Turn your CrowPanel 5.79" into a dedicated desktop command center. While ultra-wide displays often live in landscape, flipping this 272×792 panoramic e-paper display vertically unlocks the ultimate low-power, zero-glare dashboard for real-time task management, live crypto/stock tickers, and smart home telemetry. Engineered specifically for makers, this modular 3-piece enclosure features an ergonomic desktop tilt, zero-strain glass bezel clearance, integrated rear cable management, and side port access. Optimized for Bambu Studio to print flat without wasteful supports, this project bridges functional industrial design with open-source ESP32 firmware—bringing clean aesthetics and practical desktop utility to the Elecrow ecosystem.

Build the ESP-FLY, a tiny, phone-controlled ESP32 pocket drone powerful enough to fly indoors & outdoors!

An open-source 3D rotating optical prism module that turns standard WD100 digital microscopes into multi-angle inspection powerhouses.

General OverviewThe image shows a 3D rendering of a conceptual model of a quantum cryostat at scale (inspired by advanced cryogenic cooling systems, such as dilution refrigerators used for quantum computers). The structure features a yellow-gold coloring and is positioned on a light blue planar base. Main Structural ElementsExternal vertical pillars: The architecture is supported by vertical columns connecting the base section to the top platform, providing stability and defining the vertical footprint of the system. Multiple cryogenic stages: At the center of the structure, several levels or concentric disks are visible at various heights. These represent the different progressive cooling stages necessary to thermally isolate sensitive quantum components. Top flange or platform: The model is topped by a flat circular disk, simulating the upper interface plane for the experimental apparatus or control electronics.

In this project, we will build a tiny internet clock connected to your wifi to get time from NTP servers.
