Sinko box: a minimal fan-cooled case for the Orange Pi Zero 3
Oct 12,2026
Sinko is a small box that gives a family calmer internet: parental controls that run at home on an Orange Pi Zero 3, in Arabic and English (github.com/iret33/sinko). This is its enclosure.DESIGN GOALS• Closed and minimal. Only USB-C (power) and Ethernet are open, at the back. Micro-HDMI, USB-A, the microSD slot and the GPIO headers stay sealed inside, and the top is fully closed.• Quiet cooling. A 30 × 30 × 7 mm 5 V fan snaps into the lid under a round grille and blows onto a 14 × 14 mm heatsink...

High-Current ESP32 WLED Controller
Solutions Oct 10,2026
Driving 800 WS2811 pixels at full brightness draws upwards of 16 Amps (192 Watts). Attempting to route this through breadboards, thin jumper wires, or standard microcontrollers results in melted plastic, ground loops, erratic flickering, and potential fire hazards. Furthermore, the ESP32 outputs a 3.3V logic signal, while WS2811 pixels strictly require 5V, leading to degraded data packets over long wire runs.The PixelTree Node v1.0 solves this. It is a custom-engineered PCB that acts as a safe, ...

Gerber_Camera-detector-AF1_PCBWAY_READY
Oct 09,2026
Zen Tech Service is developing a ceiling-mounted hotel privacy protection device designed to detect unauthorized hidden wireless cameras.The device uses an ESP32-based electronic system and an RF detector to monitor radio-frequency activity when a hotel room is vacant. When a guest enters the room, the hotel card-holder contact activates Privacy Mode and scanning pauses. After the guest leaves, scanning resumes automatically.When suspicious RF activity is detected, the system is designed to send...

MDB Slave ESP32-S3 WROOM-1U – 4-layer cashless & telemetry board for vending machines
Glenn Oct 08,2026
## OverviewOpen-source MDB (Multi-Drop Bus) slave board for cashless payment and telemetry on vending machines. This is revision 1.4.1, built around the ESP32-S3-WROOM-1U-N16R2 module (16 MB flash / 2 MB PSRAM) with a u.FL connector, so a remote magnetic WiFi antenna can be used (the steel casing of a vending machine blocks internal antennas).## Hardware- MCU: ESP32-S3-WROOM-1U-N16R2, BOOT and EN buttons, UART and JTAG headers (2.54 mm), native USB-C- Power: AP63201WU-7 synchronous buck, 3.8 V t...
