A Tiny Robot Hides Inside a 3.5-mm Poker Chip to Cheat at Roulette With 433 MHz Radio and a Custom PCB Kevin Coda of Concept Bytes Youtube channel built a tiny remote-controlled robot inside a poker chip for Mark Rober's CrunchLabs casino challenge. The project turns a standard poker chip into a miniature mobile robot that can move across a roulette table after receiving a wireless command. To make room for the electronics, the chip was hollowed out using CNC machining and its internal steel… |

This ESP32-Powered Self-Balancing Cube Jumps With a Spring and Uses a Reaction Wheel to Land on Its Edge A maker from The Tinkering Techie has done a compact self-balancing cube that can launch itself into the air, reorient during the jump, and land upright on one of its edges. Unlike conventional self-balancing robots that continuously drive wheels against the ground, this cube uses an internal reaction wheel to control its orientation. When the motor accelerates or decelerates the spinning… |

Maker Replicated the Boston Dynamics Gripper Using Daisy-Chained Servos and 3D-Printed Fingers Maker built a Boston Dynamics–style gripper using daisy‑chained bus servos and 3D‑printed fingers. Inspired by the Electric Atlas Humanoid Robots, the design focuses on a simple three‑finger layout with a rotating thumb to move around objects of different shapes. By linking multiple servos over a single UART bus, the build keeps wiring clean while allowing independent control of each joint for… |

ESP32-S3-Based Pocket-Sized Retro Gaming Console With Brass Wires for the Frame and Wiring This is a pocket-sized retro gaming console built by HVT Lab. It's powered by an ESP32-S3 N16R8 microcontroller and plays classic games from legendary systems like Nintendo, Game Boy, and Sega. It uses a 2.4-inch IPS display, and he made the entire body of the console from 2 mm brass wire, demonstrating a unique blend of DIY electronics and metal craftsmanship. He… |

Maker Builds a 5-in-1 Cyber Deck Using an ESP32, 3.5-Inch Touchscreen Display, and Custom 3D-Printed Body Maker from the youtube channel Hacktuber recently made a custom "5-in-1 Cyber Deck" using ESP32. He demonstrated the project using two different ESP32 based development boards. One is a 2.8-inch CYD (Cheap Yellow Display) featuring an integrated touchscreen for quick prototyping, and the other is a 3.5-inch non-touch TFT display connected to an ESP32 C3 Mini, mounted onto a 3D-printed… |

Maker Turns a Normal IR TV Remote into a Functional Keyboard Using I2C for His Handheld PC In his DIY electronics project, maker Mirza Makes transformed an ordinary TV remote into a fully functional keyboard for his portable computer. The idea was to give it a soft keyboard, the kind of ones seen in TV remotes. The build centers around a high-performance Raspberry Pi 5 paired with a compact Elecrow 5-inch TFT touchscreen display to provide a… |

Maker Builds a Linked Portal Illusion Using Arduino Uno R4, Flywheel Launcher, and ToF Distance Sensors A maker from the youtube channel James' Programming has recently built a linked portal illusion using Arduino, 3D‑printed parts, and a custom aluminum frame. The setup uses two identical “portal” frames facing each other: when an object is thrown into one, it appears to instantly emerge from the other, creating a convincing real‑time portal illusion without any video tricks. … |

VolAnti: An Open-Source ESP32-S3 Device That Detects Fibre-Optic Drones With No RF Control Link, Using Sound A maker named Agam Rossen has created VolAnti, an open-source acoustic drone detector that identifies nearby multirotor drones by listening to the sound of their propellers. Unlike traditional drone detectors that look for radio-frequency signals, VolAnti focuses on the sound produced by spinning blades. This approach is particularly relevant to fibre-optic-controlled FPV drones, which send… |

ESP32-Based AI Pet Gets Sick If You Doomscroll, While Android Handles Local LLMs, STT, and TTS Offline Maker and Youtuber, Brenpoly recently built an offline AI virtual pet that lives on an ESP32 and “gets sick” when you doomscroll too much, turning screen-time guilt into a tangible, hardware-based consequence. The project makes use of the 1.8 inch touch screen display and sensors that come integrated with the Waveshare ESP32-S3 based module to create a companion that reacts to your phone usage… |

Maker Built His Quadruped Robots a Soccer Field Where Ball Tracking Improved With Less Accurate Camera Data A maker built a miniature soccer environment for Sesame, a small quadruped robot, and demonstrated the system at the 2026 Open Sauce maker event. The build includes a scaled down soccer pitch sized for the robot, along with 3D printed goals and structural components. Multiple Sesame units are controlled wirelessly using the ESP-NOW protocol, with ESP32 chips on each robot communicating with a… |

He Built a Computer That Runs on Fire Using a Stirling Engine and ESP32 C3 to Run Games and Custom Programs A maker from the Youtube channel PickentCode has built a working steampunk computer powered entirely by a Stirling engine, combining a 19th-century mechanical invention with modern electronics and retro computing. The Stirling engine was developed by Robert Stirling in 1816 as an alternative to the high-pressure steam engines of the time. Unlike a conventional internal-combustion engine, it… |

This Maker Turned a Simple Stick Into a POV Display Using a Teensy 4.1, ESP32 and Fast APA102 LEDs YouTuber Zachary McCune from Corridor Crew has turned a simple fire spinning hobby into an ambitious engineering project that can create images in the air while spinning. The project uses the principle of persistence of vision (POV), where rapidly changing lights appear to form a continuous image when moved quickly through space. Instead of using a conventional screen, the device displays an… |
