We Built an ESP32 Wall Climbing Beetle Robot We can see wall-climbing robots from hobby-level to serious problem-solving ones that are used for inspection, surveillance, cleaning, etc. When we generally talk about robots, a robot can be a firefighting robot, a human-following robot, a self-balancing robot or can be of any type that has some specific features or solves a specific kind of problem. If we talk… |

Hot Wheels Meets Embedded Engineering: Inside a 1:64 Scale FPV RC Drift Car A Hot Wheels car has been transformed into a fully functional FPV RC drift platform by YouTuber Pro Know, proving that serious embedded engineering can exist even at a 1:64 scale. The project replaces the toy’s original internals with an ESP-based microcontroller running custom firmware, paired with a purpose-built PCB that integrates control logic, power… |

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… |

DIY “Mo-chan” Desk Robot Attracts Maker Community Attention A small do-it-yourself desk robot named Mo-chan has been shared with makers, demonstrating how individuals can build simple robotics and electronics projects on their own. This project uses an ESP32-C3 microcontroller, small DC motors, an OLED screen, and a motor driver to create a robot that looks nice and functions well as a companion for a desk. The robot is constructed using a metal… |

ROHM's New Three-Phase BLDC Gate Driver Uses TriC3 to Cut Switching Loss for Medium-Voltage Motors ROHM’s new three-phase brushless DC motor gate driver uses its proprietary TriC3™ technology to minimise FET switching loss without compromising on electromagnetic interference (EMI). It is designed for motors that run on 12 to 48V power sources, meaning that applications include electric drills, industrial fans, air conditioners, and E-bikes. The TriC3™ tech helps mitigate the usual… |

Marvel Asked and a Creator Delivered a Working H.E.R.B.I.E. Built in Seven Days Marvel asked content creator Frank to build a working replica of H.E.R.B.I.E., the robotic assistant from The Fantastic Four: First Steps, for the film's blue carpet premiere. With only seven days of time and help from engineer Danny, Frank built a fully animatronic H.E.R.B.I.E. using custom 3D models and off-the-shelf components. A two-wheeled balancing robot called Diablo was used as… |

DIY 3D-Printed RC Car Hits 48 kmph with Custom ESP32 Electronics Lizard is a remote-controlled race car project published by TRDB. It’s all 3D printed components minus the wheels and powered by a custom electronics system based on the ESP32 microcontroller. Designed to be customizable, the Lizard features a rear-wheel drive system with open differential, independent suspension, and double Cardan joints. The drivetrain and chassis are printed using PETG… |

DIY Robotic Arm with Brushless DC Motors and Raspberry Pi JesseDarr’s new project is different from the usual DIY robotics project. He has made a robotic arm called dARM. It is a robotic arm with 6 degrees of freedom, and most of the parts are 3D printed. He has used brushless DC motors for its working rather than servo motors. These are the kind of motors you would usually find in more advanced machines, and they help the arm move more smoothly and… |
