Supercapacitor-Powered Electric Wind-Up Plane We have all seen old rubber band wind-up planes built by crazy makers. Tom Stanton, a youtuber, just turned one into a 21st century electric wind-up plane powered by a supercapacitor. He is an engineer and a maker who loves to mix physics, 3D printing and clean energy storage. Instead of winding up a rubber band, he used his hand crank generator to charge a supercapacitor. This stored energy… |

Porcospino Flex: Lightweight Design and Flexible Spine Enhance Robotic Performance When robots face tight spaces and unpredictable terrain, most machines come to a stop. Researchers at the University of Genoa’s RICE Lab are changing that with Porcospino Flex, a bio-inspired single-track robot designed to go where traditional wheeled or legged robots fail. Inspired by segmented invertebrates, it features a flexible 3D-printed vertebral column made from ABS and TPU, allowing… |

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… |

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… |

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… |

DIY Project Turns Treadmill into a Working 3D Printer Ivan Miranda and his team have been working on an interesting idea, turning a regular treadmill into a 3D printer and finally use it to print a full-size kayak. In their latest video, they show the first successful step toward that goal. The setup lets them print long objects in one go, which could be useful for projects like making a full-size kayak. This approach avoids the hassle of… |

This Portable Open-Source DIY 3D Printer Fits Into a Filament Box and Prints Upside Down James has announced the completion of his 3D printer called Lemontron, a new portable printer that combines smart design with a minimalist approach. Designed to fit inside a standard filament box, the Lemontron offers a surprising 180 x 180 x 165mm print volume which is comparable to popular desktop printers like the Prusa Mini, but with a completely different… |

Build A Functional Soft Robotic Gripper Using 3D Printed Mold and Silicone In a recent YouTube video, a maker called Tazer Technical has shown us how he has built his own Soft Robotic Gripper by overcoming challenges in material selection by irritative prototyping. In his earlier attempted he build a single finger robotic gripper using silicone with a Shore hardness of 25A which was too rigid, leasing to adoption of a softer silicone (10A) combined with a… |

Now you can 3D Print Your Own PCBs using a SLA 3D Printer If you have worked with electronics, at some point you have probably wondered or even tried to make your own PCBs at home. Thanks to the magic of 3D printing, that dream is now a reality. Stephen Hawes, CEO of Opulo, on his YouTube channel shows us how you can use an SLA 3D printer to etch your very own PCBs. First, you'll need to… |

Core-RΘ: A New Non-Planar Approach to 3D Printing 3D printing has revolutionised modern manufacturing and prototyping, becoming a staple across industries and hobbyist communities alike. The sheer variety of 3D printers on the market today is staggering, with the majority of them employing Cartesian or planar kinematics. These systems operate within the familiar X, Y, and Z axes, building objects layer by flat layer. Other innovative designs… |

How to use TMC2208 Stepper Motor Driver with Arduino Today, we are going to investigate the TMC2208 stepper motor driver, a commonly used driver module that performs well with 2-phase bipolar stepper motors. The TMC2208 module is manufactured by Trinamic (a German company that specialises in motion control products); it has become popular due to its performance in a more efficient manner and provides silent operation.… |

Future of 3D Printing: Researchers Demonstrate Tiny Chip-Based 3D Printer Researchers from MIT and the University of Texas at Austin have demonstrated the first chip-based 3D printer, potentially revolutionizing the 3D printing landscape. At present it is a novel device, small enough to fit in the palm of a hand, features a single millimeter-scale photonic chip that directs reconfigurable beams of light into a resin, which then cures into… |
