The future of air transport

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!!

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

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!

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.

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

This project aims to accelerate the process of identifying soil density values from the subgrade, subbase, and base course layers by integrating vibration, speed, and acceleration sensors connected to an Arduino Mega 2560 microcontroller. The data generated enables real-time monitoring and adjustment during the compaction process in accordance with SNI (Indonesian National Standard) 1738-2011.
