TerraBlade - Ultra-Low-Power Capacitive Soil Moisture Sensor
Solutions May 23,2026
Key Engineering FeaturesTrue Digital Capacitive Sensing: Ditching the noisy, drifty analog peak-detectors of standard cheap soil sensors. The FR4 PCB blade acts as the timing capacitor for an industrial-grade TLC555IDR oscillator. It outputs a raw, clean frequency directly to the ESP32's hardware Pulse Counter (PCNT) for flawless, high-resolution moisture data.Zero-Leakage "Parasitic" Power: The 555 timer is powered directly by an ESP32 GPIO pin. The ESP32 wakes up, powers the sensor, takes a re...

Granit — Open Source PCIe SATA Carrier Board for Raspberry Pi CM4
Laenzlinger May 14,2026
Granit is a custom carrier board for the Raspberry Pi CM4 Compute Module, purpose-built asan offsite backup appliance. The device connects a standard SATA hard disk, receivesencrypted backups over Gigabit Ethernet, and shuts down between backup windows — consumingnear-zero power when idle. It is designed to be left at a trusted remote location (afriend's house, a family member's basement) and managed entirely over a WireGuard VPN.The PCB is a 4-layer design with impedance-controlled differential...
