A maker has built a two-legged walking robot using just five RC servos, an ESP32 microcontroller, and 3D-printed parts, making it the third entry in a series of accessible open-source robot designs. The project follows earlier builds in the same series: a mini robot dog and a hexapod. The creator set two design requirements: the robot must actively balance as it walks, and it must lift its…
The main part of the project is a LEGO RC WALL-E itself. He initially planned to use a FlySky controller and its remote, but later switched to a PS4 controller as it is much more compact and offers more controls. He used an ESP32 as the receiver. After some research, he decided to use the Bluetooth functionality of the ESP32 for communication. Two N20 motors along with an L298N motor driver…
Flipper Devices has officially stepped beyond the world of pocket-sized hacking tools with the introduction of Flipper One, a new open-source Linux cyberdeck designed for networking, SDR experimentation, portable computing, and local AI workloads. Unlike the Flipper Zero, which focused on low-level wireless protocols and embedded systems. Flipper One is being built as a far more capable and…
Raspberry Pi recently hosted an AMA session on Reddit featuring CEO Eben Upton, CTO of Hardware Engineering James Adams, and CTO of Software Engineering Gordon Hollingworth.
The discussion covered a wide range of topics including Raspberry Pi 6, Zero-series shortages, AI, industrial adoption, and the future of the RP2040 ecosystem. Here are some of the most important announcements and…
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…
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…
May 20, 2026– Mouser Electronics, Inc., the industry's leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components™, invites design engineers, embedded developers, and technology professionals across India to the Mouser India Technical Roadshow 2026. The three-city programme opens in Pune on 12 June, followed by Bangalore on 18 June…
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,…
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…
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,…
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…
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…
