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…
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…
A maker recently documented the development of ESP-BLAST, a custom aerodynamic “rocket drone” designed for high-speed flight. Unlike typical quadcopters with exposed frames, this drone uses a streamlined bullet-shaped body to reduce drag while four small 1104 brushless motors drive 2.5-inch propellers. At the center of the system is an ESP32-S3, which acts as the…
A neatly designed electromechanical clock shared on YouTube is drawing interest from hobbyists and electronics enthusiasts alike. The project is inspired by the marble clock concept originally created by Ivan Miranda, but the creator redesigned it into a smaller version that can easily fit on a desk. Instead of simply copying the original build, the maker simplified the structure while keeping…
A maker recently engineered an extreme, portable lighting system built around one of the brightest LEDs available, capable of producing more than 120,000 lumens while consuming roughly 1.5 kW of power. Because such an LED generates enormous heat, traditional cooling methods quickly fail. To prevent thermal damage, the project focuses heavily on a liquid-cooling system designed to dissipate…
Russian DIY creator AlexGyver has completed his latest “Challenge Accepted” project: a big, good-looking wall clock made using 24 small stepper motors called BKA30D-R5. These are the same kind of tiny motors you find inside car dashboards to move speedometer or fuel gauge needles. Each motor has two shafts, but he only uses one to control a custom pointer. With 24 of…
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…
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…
HackyFi, one of the tiniest yet most capable USB-C development dongles built for hackers, makers, educators, and security researchers. Powered by the Raspberry Pi RP2350A microcontroller, the ultra-compact device integrates a 0.85-inch LCD screen, dual programmable buttons, RGB status LED, 2MB onboard flash, and a microSD card slot all inside a keychain-sized form factor. Designed to challenge…
The ESP32 Bus Pirate project has received a major update, further transforming it into a powerful and affordable embedded systems debugging platform. Originally inspired by the Classic Bus Pirate, this firmware-based implementation allows low-cost ESP32-S3 development boards to function as multi-protocol communication tools. Like the original hardware tool, it supports common interfaces such…
A maker shared an electronics project on Digikey that explains an automatic system for recognizing and organizing resistors using an Arduino Uno Q. Zach Hipps did the work and looked for methods to cut down the time needed to manually figure out resistor values after making electronics prototypes. The project uses computer vision methods instead of manually reading…
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…
