ESP32-Powered Laser Projector Brings Retro Vector Graphics Back to Life A new DIY laser projector project from breq.dev is getting attention in the maker community for mixing old-school vector graphics with modern embedded hardware. Built by Brooke Chalmers and Mia Kiesman, the system uses a pair of galvanometer mirrors to steer RGB laser beams and draw graphics directly in the air. Instead of using a normal display panel, the projector creates smooth vector-style… |

Arduino Obstacle-Avoiding Robot Rebuilt 7 Times Larger A Youtube channel named UncleStem has taken DIY robotics to a completely new level by building a giant obstacle-avoiding robot powered by a fully functional oversized Arduino Uno. The project recreates a classic Arduino obstacle avoidance robot at seven times the original size while still maintaining real working electronics inside. From giant DC motors and oversized jumper wires to a massive… |

New Robotics Training Method Helps Simulated Skills Work in Reality Researchers at Aston University have developed a new AI-based robot training approach aimed at reducing the long-standing “sim-to-real” gap in robotics. The work focuses on improving how robots transfer skills learned in simulation into unpredictable real-world environments, where differences in material properties, sensor noise, and physical interaction often cause systems to fail despite… |

bUniProbe, a Multi-Protocol Hardware Debugger with a Web Interface There's no shortage of tools to test and debug hardware, but not many feature interfaces for SPI, I²C, UART, CAN, GPIO, ADC, and DAC in one device. bUniProbe is one of the few, and its hardware side is just half the story. It hosts its own web interface over Wi-Fi, so anyone on the network can open a browser, connect, and start working. This means multiple users can work together without the… |

The Unpickable Lock Shane Wighton, the engineer behind the popular Works By Design channel, developed this innovative “unpickable” lock. Known for building complex mechanical systems, he set out to solve a long-standing problem in security: how to create a lock that a key can open but tools cannot. Traditional locks rely on pin tumbler mechanisms, which can often be manipulated with enough skill. His approach,… |

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… |
