CrowCaddie transforms the Elecrow CrowPanel 7.0" ESP32-S3 HMI into an autonomous, commercial-grade golf cart terminal combining a visual caddie HUD, long-range fleet telemetry, and an active safety governor. Operating on an offline-first architecture, CrowCaddie renders high-resolution 800×480 hole maps and live satellite yardages to the pin at 60 FPS using LVGL. When carts approach restricted turf (greens, bunkers, hazard zones), high-speed point-in-polygon algorithms trigger an onboard relay spliced into the cart's forward microswitch—safely cutting forward acceleration while leaving reverse open so golfers can back away. For fleet tracking, carts broadcast compact 20-byte telemetry over 915MHz LoRa to a silent clubhouse gateway kilometers away. At night, carts wake on barn WiFi to pull delta updates—downloading course blueprints, 280×150 sponsor banners, and calibration offsets in under 2 seconds.

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.

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

With a low-cost ESP32 and WM8960, we built a complete real-time stereo parametric EQ with professional-style controls

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.

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

A US-based health tech startup came to us with a working smartwatch prototype built on dev boards and jumper wires. It measured heart rate, SpO2, and skin temperature, synced over BLE, and lasted about 14 hours on a 200 mAh battery.

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

This experiment clearly shows how much the enclosure can influence the sound of even a tiny and inexpensive full-range driver.
