Edinburgh-based Singular Photonics has launched Litavis, the world's first SPAD image sensor with on-chip photon processing that combines photon counting, timing, and statistical analysis on a single chip. By performing analysis directly on the sensor rather than sending raw data to external processors, Litavis reduces data transfer requirements and enables lower-latency, more power-efficient imaging systems. The software-configurable sensor supports multiple imaging modes including photon-counting, time-correlated single-photon counting, and coincidence detection, with applications spanning machine vision, robotics, quantum sensing, and medical imaging.
A developer documents their first DIY electronics project: building a soil moisture monitoring system for a mint plant using a TinyGo-powered ESP32 microcontroller. The system will measure soil moisture and send notifications via Telegram when the plant needs water, powered by rechargeable batteries.
A developer recreated Apple's iPhone Duo folding-screen animation on Samsung's Galaxy Z Fold 8 using the device's hinge sensor, but the effect remains a limited app-based demo rather than a system-wide feature. The animation uses motion-sensor data and timed transitions to create the illusion of the display dissolving between the phone's two screens, though Samsung would need to implement it at the system level for wider availability.
A frustrated developer struggles to troubleshoot a malfunctioning ranging sensor module connected to an ESP32 microcontroller, leading to reflections on hope, disappointment, and perseverance through failed attempts and unmet expectations.
