Intelligent 3D Reconstruction Using Advanced Point Cloud Algorithms A YouTube channel named 9nl has developed an open-source project on GitHub that is gaining attention for its approach to 3D reconstruction using point cloud data. The system combines both hardware and software elements, where a compact embedded platform such as the Raspberry Pi can be used for capturing spatial data through connected sensors like cameras or LiDAR. This data, consisting of… |

Raspberry Pi-Based 5” Portable Homelab Michael Klements built this 5-inch Raspberry Pi based lab rack by scaling down his actual lab rack by 50%, making it eight times smaller while preserving full rack-mount functionality. 3D printed using just 220g of filament with precision M3 brass inserts and screws, this portable homelab fits in your backpack yet powers a complete network stack. The setup includes an OpenWrt router running on… |

Reticulum : A Decentralized Networking Stack A recent project showcases Reticulum, a cryptography-based networking stack designed to build a decentralized, infrastructure-independent communication network. Unlike traditional mesh systems that depend on specific radios sharing the same frequency, Reticulum abstracts hardware into interchangeable “interfaces.” Whether the link is LoRa, Wi-Fi, Ethernet, or packet radio, the protocol… |

Exploring PD240W: Using USB Power Delivery as a Bench Supply Alternative Bulky bench power supplies and dedicated adapters are still common on electronics workbenches, but they are often inconvenient to carry around and overkill for many portable or field setups. With USB Power Delivery and newer GaN chargers now able to provide high power from compact adapters, developers are starting to treat USB-C as a serious power source rather than just a charging port. Theo… |

A DIY Cinema Camera Built Around a Raspberry Pi When it comes to filmmaking, cinema cameras are often one of the most expensive and unavoidable pieces of equipment. This reality has led many independent creators and engineers to explore lower-cost alternatives, including open-source and DIY camera platforms. In a recent project, Matthew Trahan documented the process of building a compact cinema-style camera using… |

Memento SafeEdge Guardian - AI Child Safety Monitoring for Home Danger Zones By Yash Izate A home is meant to be the safest place for a child, yet falls remain the leading cause of injury in domestic environments. Studies show that nearly 60% of home injuries in children are due to falls, with incidents from heights such as balconies, staircases, and windows being the most severe. Hospital reports indicate… |

Interfacing the RTC Module with Raspberry Pi Pico In this guide, we will create a simple and precise digital clock using the Raspberry Pi Pico RTC DS3231 Module through the Arduino IDE. We will use a 16x2 I²C LCD screen to display the information. Since the screen is small, we will write smart code that changes what is shown on the screen. For a few seconds, it will display the time and date, and then switch to show the temperature.… |

Interfacing SD Card Module with Raspberry Pi Pico The Raspberry Pi Pico SD card module is a simple yet very handy add-on that lets you store and access a lot of data using a standard microSD card. When interfacing the SD card module with Raspberry Pi Pico, you gain access to gigabytes of storage for sensor logging, configuration files, and time-stamped data. This comprehensive guide will show you how to build… |

How to Build a Raspberry Pi Wi-Fi Router with RaspAP Over the years, I’ve collected a few Raspberry Pi boards, my trusty Pi 4 and even an older Pi 3 that was gathering dust in a drawer. Instead of letting them sit unused, I decided to give them a new life by turning them into something surprisingly practical: a Raspberry Pi WiFi router with built-in ad-blocking capabilities. With the… |
