A hobbyist built an automatic plant watering system using an Arduino Nano, capacitive moisture sensor, and aquarium pump controlled by a MOSFET-based circuit. The system reads soil moisture values and triggers the pump to dispense 100ml of water when soil dries below a threshold, with a one-hour lockout to prevent overwatering.
A software developer in the 1990s built a real-time GPS moving map display on a 25MHz 486-SX processor with minimal floating-point math, using the Hipparchus library's integer-based algorithms. The system was significantly faster than consumer GPS devices that emerged years later, but the developer lost access to the project when the client faced financial difficulties.
A lightweight anomaly detection daemon (sentinel-imxd) for NXP i.MX 8M Plus boards that monitors systemd journal and D-Bus events, normalizes them into INT8 vectors, and runs TensorFlow Lite autoencoders on the Vivante NPU to detect anomalies via reconstruction loss thresholding, with training on a host Docker environment and deployment via SSH.
Swift 6.4 has been released, bringing improvements across the stack including cross-platform build consistency, stable subprocess support, enhanced interoperability with C++ and Java, faster WebAssembly performance, and better embedded Swift capabilities. The release simplifies everyday programming with features like optional type syntax improvements, compiler warning control, async defer blocks, and enhanced Foundation APIs.
JetKVM Mini is a low-cost KVM over IP device using an ESP32-P4X microcontroller instead of Linux, offering 1080p video capture via H.264 encoding and Ethernet or WiFi connectivity in a compact 42×42×23mm form factor. Priced at $39 (or $33 in bundles), it maintains compatibility with the original JetKVM's web interface and cloud services while reducing costs by eliminating Linux RAM and flash requirements.
JetKVM Mini is an affordable remote management device starting at $33, featuring a compact aluminium design with 1080p video capture, keyboard/mouse control, and web interface access. Available in wired Ethernet ($39) or wireless ($42) models, it uses an ESP32-P4X microcontroller and supports the same cloud, extensions, and updates as the full JetKVM system.
