This Salamander Robot Got a New Spine and Smarter Gait YouTuber soiboi soft upgraded his robot modelled after a salamander. The project is bio-inspired, copying designs and behaviors from the amphibian. The robot uses soft actuators and rolling diaphragms, making it flexible and allowing for clean and natural movements. The diaphragm pumps and solenoid valves controlled by an Arduino make up the electrofluidic system. The legs are inspired… |

Inside the DIY Robot That Rolls Like a Drone on the Floor Max Imagination has published the making of a DIY spherical robot that moves by rolling inside a transparent plastic ball. It’s meant to entertain pets, explore tight spaces, and be driven via smartphone, like an FPV drone that rolls on the floor. The project uses an XIAO ESP32S3 Sense from Seeed Studio, which includes Wi-Fi, a 2MP camera, a mic, and a microSD slot. Two geared motors… |

This Transformer Robot Was Built to Be Ridden, Not Just Looked At A maker built a real-life transformer robot that switches from a car to a robot, just like in the movies. The build is designed for someone to ride, much like a toy car. The robot uses Gimson Robotics 99.5:1 gearhead motors with additional 3D-printed two-stage gear reductions. Six motor assemblies power all leg joints. It uses AS5047 magnetic encoders to track joint positions, allowing… |

DUAWLFIN, A Drone That Can Both Fly and Drive Using the Same Motors Researchers from UC Berkeley have developed a unique hybrid drone that both flies like a quadcopter and drives on the ground using the same motors. Unlike the average drone that needs separate motors or propellers to move on the ground, DUAWLFIN uses a clever mechanical system called a differential drivetrain to switch between flight and wheels. The spinning of propellers is not required while… |

DIY Piano Doorbell That Replaces the Classic Chime with Musical Notes A simple piano doorbell that replaces the usual chime with real piano notes was demonstrated in a recent project published by Arpan Mondal. The system combines microcontroller-based control with audio playback to create an interactive doorbell. At its core is an ESP32-S3, which takes inputs from 5 keys styled like a tiny piano. Each key is built using micro limit switches and connected… |

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… |

3D-Printed Hovercraft Glides Over Land and Water A maker has designed an impressive DIY hovercraft that can glide over water, grass, and hard surfaces using a powerful air-cushion system. The body is made from four modular parts, 3D printed to fit standard printer sizes, with strong mounting points and precision bearings for smooth mechanical movement. The hovercraft uses two motors, one for lift and one for forward thrust. A 5-inch… |

A DIY Bottle Labeler Automated with Arduino Labeling bottles manually takes a good chunk of time and effort. Addressing this, the YouTube channel Easy Home Made Projects has developed a DIY automatic labeling machine using an Arduino Nano, a smart solution to speed up labeling on cylindrical bottles. The project includes 3D-printed parts, wooden supports, and a repurposed mini conveyor belt. The working combines stepper motors,… |

Junk Hoverboard to DIY Electric Ride on One Wheel A combination of an old hoverboard, a go-kart tire, and some clever engineering apparently gets you a functional one-wheel electric ride that rides like a snowboard both on and off the road. A DIY creator from the YouTube channel Well Done Tips took what he believes to be one of the most useless electric rides ever made and transformed it into a surprisingly cool custom one-wheel electric… |

This Student-Built Satellite Turns Into a Drone While Landing Here is something you don’t see every day, a satellite that turns into a drone and guides itself back to the ground, without the help of a parachute. I Build Stuff youtuber recently made this happen for the CanSat competition, and honestly, it is one of those “simple idea, tricky execution” projects that ended up working out surprisingly well. Instead of using a parachute to land, like… |

DIY Automatic Desk Dustbin with Iris Lid A DIY The Wrench maker has built a smart desk dustbin with an automatic iris-style lid, adding both functionality and a unique touch to a workspace. After some adjustments, the final design was printed successfully using a 3D printer using a design made in Fusion 360. Different filament colors were used to make the dustbin visually appealing. The smart feature of the dustbin is… |
