Build an ESP32 Voice Controlled Drone with LiteWing using Python Drones are amazing little machines, but most of the time they are controlled using remotes filled with buttons and joysticks. While experimenting with our LiteWing drone, we started wondering, wouldn’t it be cool if the drone could simply listen to what we say? That idea eventually turned into this project. We built a voice controlled drone using ESP32 for the… |

Building Rocky From Project Hail Mary in Real Life Leviathan Engineering, a tech-focused YouTube channel, has recreated Rocky from Project Hail Mary as a real AI-powered robot by combining mechanical design, on-device speech recognition, and modern AI that responds in real time. The robot runs on a Raspberry Pi 5 (4GB RAM) and uses 10 MG996R servo motors for movement. A major part of what makes this build impressive is the software… |

DIY FPV Goggles: HD Drone View Without the High Cost DIY creator Artur Pękosz has shown that high-quality drone viewing doesn’t need expensive or closed systems, By building a fully functional pair of FPV goggles from scratch. Using the open-source OpenIPC HD wireless transmission system, the creator designed a custom solution that captures, transmits, and displays live HD video. The project replaces traditional proprietary hardware with a… |

ESP32 Bluetooth Jammer Using Dual NRF24L01 Modules Bluetooth communication is everywhere. Due to its low power consumption, we can see it in a lot of our day-to-day gadgets. Behind the scenes, it's all about signals. Let’s explore what really happens when data is transmitted or disturbed via Bluetooth. This project is based on an ESP32 and two NRF24L01 modules, and we are going to learn how we can generate a 2.4 GHz… |

ESP32-S3 Sensor Hub: 8 Sensors on a Single Compact PCB Maker MagmaBow has unveiled a high-density security development board that challenges the traditional "one sensor, one device" model. Built around the powerful ESP32-S3 module, the project successfully integrates eight distinct sensors including thermal IR, Time-of-Flight distance tracking, and dual accelerometers onto a single, compact PCB. By consolidating these components into one footprint… |

DIY Magnetic 6DoF SpaceMouse Brings Pro-Level 3D Control Hardware developer and Maker Salim Benbouziyane has created an open-source, fully functional 6-DoF (six degrees of freedom) navigation controller, offering a DIY alternative to commercial SpaceMouse devices used in CAD and 3D modeling workflows. Designed for tools like Fusion 360, Blender, and KiCad, the controller allows users to pan, zoom, and rotate 3D objects simultaneously using a single… |

This Nerf Gun Uses AI to Predict When You’ll Pull the Trigger A hobbyist maker has taken Nerf modding to the next level by integrating machine learning into a custom-built blaster called the Stinger. High-performance "flywheel" blasters usually suffer from a slight delay while the motors spin up to full speed, which can be the difference between a hit or a miss in a fast-paced game. To solve this, creator "stingernerf" bypassed traditional hardware… |

DIY Handheld Arduino Game Console With 10 Retro Games Tired of building the same old Arduino projects like blinking LEDs, temperature monitors, and line-following robots? Now it’s time for something fun. It’s time to turn your skills into entertainment by creating your very own Arduino game console project. Instead of just testing circuits, imagine powering up a device you built yourself and jumping straight into… |

Build a Simple Optocoupler Tester Circuit for Fault Detection Optocouplers frequently fail without a sound in labs or during repairs. The package appears to be undamaged, but there may be no output from the LED source or the photosensitive output stage. Testing for failure with a multimeter is only partially effective, whereas a dedicated optocoupler testing circuit provides clear results in just seconds. For related tutorials… |

Smallest DIY ESP32 Brushless Rocket Drone A maker recently documented the development of ESP-BLAST, a custom aerodynamic “rocket drone” designed for high-speed flight. Unlike typical quadcopters with exposed frames, this drone uses a streamlined bullet-shaped body to reduce drag while four small 1104 brushless motors drive 2.5-inch propellers. At the center of the system is an ESP32-S3, which acts as the… |

A Desk Clock That Uses Marbles to Tell Time A neatly designed electromechanical clock shared on YouTube is drawing interest from hobbyists and electronics enthusiasts alike. The project is inspired by the marble clock concept originally created by Ivan Miranda, but the creator redesigned it into a smaller version that can easily fit on a desk. Instead of simply copying the original build, the maker simplified the structure while keeping… |

Minimal Aesthetic Clock Using Simple Motor Mechanism Russian DIY creator AlexGyver has completed his latest “Challenge Accepted” project: a big, good-looking wall clock made using 24 small stepper motors called BKA30D-R5. These are the same kind of tiny motors you find inside car dashboards to move speedometer or fuel gauge needles. Each motor has two shafts, but he only uses one to control a custom pointer. With 24 of… |
