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.

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

One of the best Chinese produced Energy Monitor ASICs now easier than ever to use

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.

Stop using clunky physical buttons for your Arduino projects. Instead, why not use the TTP223 capacitive touch sensor.

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.

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.

An ATmega8-based dusk-to-dawn switch that automates lighting using an LDR sensor, featuring software hysteresis to prevent flickering and adjustable light thresholds.

HMI Dashboard for Euro Truck Simulator 2. Powered by an ESP32-S3 running FreeRTOS and LVGL 8.3, we deliver ultra-smooth 60FPS telemetry that outshines standard tablet-based apps. It is a standalone, low-latency, and professional-grade digital cluster that transforms your truck simulation into a premium driving experience.
