Making A Functional Arm Cannon For Bungie Engineering a Functional Arm Cannon for the Makers of Halo

A maker built a real, functional replica of the arm cannon belonging to Vandal, a character in Bungie's video game Marathon, for use in a commercial. The builder had 18 days to complete the entire project.

The build was divided into two main subsystems: a forearm clamshell mechanism and an internal barrel assembly. Bungie provided game asset mesh files for reference but, because the…

DIY Voice Recorder Uses AI to Turn Spoken Ideas into Summarized Notes This DIY Voice Recorder Uses AI to Turn Spoken Ideas into Summarized Notes

A maker recently built a compact portable voice recorder designed specifically for capturing ideas before they are forgotten. Instead of relying on a smartphone app, the project focuses on a dedicated hardware workflow built around an ESP32, combining local audio recording with AI-based transcription and summarization. The device records audio directly to an SD card, provides onboard playback…

SpikerBot represents the future direction of brain-computer interfaces and neuro-inspired robotics SpikerBot Turns Neural Signals into Real-Time Robotic Motion

A revolutionary neuroscience robotics project called SpikerBot is creating excitement among technology enthusiasts, engineering students, and STEM researchers across the world. Developed by Backyard Brains, the innovative platform combines neural signal processing, embedded systems, robotics, and bioengineering into a single interactive learning experience. Recently launched on Kickstarter,…

A Simple DIY Ultra Long-Range Night Vision Build A Homemade Approach to Long-Range Night Vision

Most infrared night-vision systems are limited to relatively short distances mainly because standard IR LEDs spread light too widely to be effective over long ranges. Curious about the practical limits of infrared imaging, the independent engineering channel Project 326 developed a custom-built system aimed at long-range nighttime observation.  The system combined a modified low cost…

Unitree's New Mecha Robot Unitree Unveils $650,000 Pilotable Mecha Robot

Chinese robotics company Unitree has launched the GD01, a giant pilotable mecha robot priced at $650,000. The Hangzhou-based startup, known for producing humanoid and four-legged robots, revealed the product in a promotional video. The company confirmed to WIRED that the GD01 is a real product available for purchase.

The GD01 weighs 500 kilograms and is capable of walking, crouching,…

Tracking Cows Without Cell Towers A Custom LoRa Farm Network What Happens When You Build a Private Network Just to Track Cows?

A development team recently built a custom long-range livestock tracking system designed specifically for farms located in mountainous regions with poor cellular coverage. Instead of relying on standard GPS trackers that require 4G connectivity, the project uses a private LoRa-based communication network to help farmers monitor cattle positions in real time. The complete setup consists of…

Clock With Water as Pixels Clock Uses Water Bottles as Pixels With Membrane Pumps and Servos

Maker Strange Inventions has built a water-based digital clock in which 60 small bottles act as individual pixels, collectively forming numerals to display the time. The bottles, sourced at 10 cents each, brought the total project cost to approximately $580. Each bottle is filled or emptied with dyed water to switch its pixel state on or off, with the display controlled by a microcontroller…

ESP32-Powered Laser Projector ESP32-Powered Laser Projector Brings Retro Vector Graphics Back to Life

A new DIY laser projector project from breq.dev is getting attention in the maker community for mixing old-school vector graphics with modern embedded hardware. Built by Brooke Chalmers and Mia Kiesman, the system uses a pair of galvanometer mirrors to steer RGB laser beams and draw graphics directly in the air. Instead of using a normal display panel, the projector creates smooth vector-style…

Giant Arduino Obstacle Avoidance Robot Built 7 Times Bigger Than Normal Arduino Obstacle-Avoiding Robot Rebuilt 7 Times Larger

A Youtube channel named UncleStem has taken DIY robotics to a completely new level by building a giant obstacle-avoiding robot powered by a fully functional oversized Arduino Uno. The project recreates a classic Arduino obstacle avoidance robot at seven times the original size while still maintaining real working electronics inside. From giant DC motors and oversized jumper wires to a massive…

Leviathan Engineering Builds AI Powered Rocky Robot Building Rocky From Project Hail Mary in Real Life

Leviathan Engineering, a tech-focused YouTube channel, has recreated Rocky from Project Hail Mary as a real AI-powered robot by combining mechanical design, on-device speech recognition, and modern AI that responds in real time. The robot runs on a Raspberry Pi 5 (4GB RAM) and uses 10 MG996R servo motors for movement.

A major part of what makes this build impressive is the software…

AI Training Method Reduces Robotics Sim-To-Real Gap New Robotics Training Method Helps Simulated Skills Work in Reality

Researchers at Aston University have developed a new AI-based robot training approach aimed at reducing the long-standing “sim-to-real” gap in robotics. The work focuses on improving how robots transfer skills learned in simulation into unpredictable real-world environments, where differences in material properties, sensor noise, and physical interaction often cause systems to fail despite…
