ESP32-S3 based MP3 player that combines retro aesthetics with modern, production-grade hardware architecture.

A unique combination of astronomy, embedded programming and ambient lighting that transforms an ESP32-powered display into a realistic real-time Moon simulator.

This project is a compact stereo Hi-Fi R2R NOS DAC based on two classic Burr-Brown PCM58 18-bit converters, with one DAC chip dedicated to each audio channel.

These amplifiers prove that a well-designed and carefully built analog circuit can survive decades of hard use and still perform reliably.

This is a 24VDC to 12VDC / 500mA dual power supply project.

Vulcan Radar is a dedicated ESP32-P4 desktop aircraft tracker built around an Elecrow 5-inch CrowPanel HMI display. It connects over Wi-Fi to a custom cloud API, processes live aircraft data and plots nearby traffic on a radar-style touchscreen interface with physical range control.

Wi-Fi HaLow successfully bridges the gap between traditional Wi-Fi and LoRaWAN by combining long range, low power consumption, and enough bandwidth for real-time video streaming. It is a promising technology for the next generation of IoT and smart surveillance systems.

This project demonstrates that practical object recognition does not always require complex machine learning frameworks. Using only the built-in camera, display, and processing power of the UNIHIKER K10, it is possible to create a simple, fast, and effective object recognition system that can be trained directly by the user.

Pocket Admin Toolkit v2 turns the Elecrow 2.8-inch ESP32 CrowPanel into a compact touchscreen toolkit for Linux, networking, DevOps and everyday system administration. The first version proved that a small ESP32 display could provide fast answers without opening a laptop or searching through online documentation. Version 2 expands the project into eight practical tools: • CIDR and IPv4 subnet calculator • VLSM network planner • World clock and time-zone converter • Cron generator and parser • Storage and backup capacity planner • Visual Linux chmod calculator • Wi-Fi and BLE wireless scanner • HTTP status code and TCP/UDP port reference Most tools work completely offline. No cloud service, backend, account, API key or Wi-Fi password is required. Wi-Fi and BLE remain disabled until the Wireless Scanner is opened, and the toolkit scans nearby signals without connecting to a network. Fast answers, local calculations and useful admin tools — all running directly on a 320 × 240 ESP32 to
