The nRF9151 MicroMod Processor is a compact cellular IoT module built around Nordic Semiconductor’s nRF9151 System-in-Package (SiP) and designed to work seamlessly with SparkFun’s MicroMod ecosystem. Using an M.2 E-Key connector, the 22 × 22 mm board plugs directly into compatible MicroMod carrier boards, making it easy to add cellular and positioning capabilities without complex wiring or…
A creative maker has developed an impressive self-playing chessboard that can automatically move pieces using magnets and detect their positions. The board is equipped with magnetic sensors beneath each square, while each chess piece has a small magnet on its base, allowing the system to precisely track every piece. An ESP32 microcontroller is part of the setup, handling some hardware…
A maker has completed and demonstrated a remote-controlled bionic butterfly, sharing the build process in a recent online video. The project involved assembling a lightweight artificial butterfly with flapping wings driven by remote control components. Viewers were shown the step-by-step construction, including key mechanical and electronic elements of the flyer.
According to the video…
YouTuber Coding with Lewis recently demonstrated how an AI model can be given a physical body by converting an RC car into a fully autonomous wilderness explorer. Using Claude 3.5 Opus as the decision-making engine and a Raspberry Pi 5 as the onboard controller, the project bridges digital intelligence with real-world robotics, allowing the vehicle to navigate snowy forest terrain completely…
Thermal imaging drones are no longer limited to military or industrial use. A YouTuber named Hoarder Sam demonstrates how a thermal drone can be built at a relatively low cost, opening the door for hobbyists, students, and innovators to explore heat-based vision technology. The project highlights how modern sensors and compact electronics are making advanced imaging tools more accessible than…
Espressif has unveiled the ESP32-E22, the company’s first Wi-Fi 6E system-on-chip and the start of a new lineup focused on high-performance wireless connectivity. Designed as a radio co-processor (RCP), the device handles Wi-Fi and Bluetooth tasks independently, allowing the main host processor to concentrate on application logic rather than networking overhead. The…
A biomedical engineering student, Sudarshan VasanthaKumar, has developed a vision-based, touchless gesture interface designed for use in sterile medical environments. The system allows surgeons to rotate, zoom, and inspect 3D medical models without touching a mouse, keyboard, or screen, addressing a challenge in operating rooms where sterility is critical.
The project, called Bio-Vision…
Shrinking consumer electronics to their practical limits is a recurring theme in the DIY hardware space, and a recent project from the YouTube channel Gadget Industry takes that idea to an impressive extreme. The build centers on a Bluetooth speaker so small it undercuts the size of a single AirPods earbud, yet still manages to function like a conventional portable speaker. At the core of the…
Nowadays, many people enjoy keeping a small desk robot in their workspace. These little companions not only add a playful touch to the desk but also help bring out the inner child and provide a brief escape from daily stress. Among the latest additions to this trend is the Deskimon, a compact and creative 3D-printed desk robot. Unlike other desk robots that require separate components for the…
A new open-source quadruped robot called Sesame Robot is making legged robotics more affordable and accessible. Developed by Dorian Todd, Sesame is built using an ESP32 microcontroller, 3D-printed parts, and eight low-cost servos, keeping the total build cost around $50–60. With complete CAD files, firmware, and detailed assembly guides available on GitHub, users can easily build, customize,…
Ever thought of controlling your computer using buttons and a knob that actually feel different when you use them? Most input devices, like keyboards and mice, only give visual feedback on the screen and do not provide any physical sensation to indicate how an action feels. The Macropad changes this experience by adding the sense of touch to everyday computer controls. This is a six-button…
This is a simpler, more beginner friendly version of the original SmartKnob designed to make smart haptic controls easier to build and understand. By removing much of the complexity found in earlier designs, this version is easier to assemble and supports more motor options, making it an approachable project for hobbyists and first time builders alike.
Kokensha Tech redesigned the…
