How to Use ESP32-CAM for Face Detection Using CircuitDigest Cloud Have you ever watched a movie where a system instantly detects a person’s face, like in security doors or smart targeting systems, and thought, “This looks too complex to build in real life?” It might seem like something only high-end systems can do, but the reality today is very different. With compact and powerful modules like the ESP32-CAM, building an ESP32-CAM… |

PolyCast5 Combines Wi-Fi, LoRa, Bluetooth, IR, and ESP-NOW on an ESP32-C5 Platform If carrying a TV remote, a smart home controller, a password manager, a wireless keyboard, and a long-range IoT transmitter sounds excessive, the PolyCast5 aims to combine all of them into a single handheld device. Built around the ESP32-C5 microcontroller, the open-source gadget brings together five wireless technologies Infrared (IR), dual-band Wi-Fi, LoRa, Bluetooth 5.0/BLE, and ESP-… |

Five-Servo Bipedal Robot Walks and Self-Balances on a Budget A maker has built a two-legged walking robot using just five RC servos, an ESP32 microcontroller, and 3D-printed parts, making it the third entry in a series of accessible open-source robot designs. The project follows earlier builds in the same series: a mini robot dog and a hexapod. The creator set two design requirements: the robot must actively balance as it walks, and it must lift its… |

DIY LEGO RC WALL-E Robot Using ESP32 and a PS4 Controller The main part of the project is a LEGO RC WALL-E itself. He initially planned to use a FlySky controller and its remote, but later switched to a PS4 controller as it is much more compact and offers more controls. He used an ESP32 as the receiver. After some research, he decided to use the Bluetooth functionality of the ESP32 for communication. Two N20 motors along with an L298N motor driver… |

Raspberry Pi Reveals Pi 6 Timeline, Zero 3 Plans, and the Real Reason Behind Stock Shortages Raspberry Pi recently hosted an AMA session on Reddit featuring CEO Eben Upton, CTO of Hardware Engineering James Adams, and CTO of Software Engineering Gordon Hollingworth. The discussion covered a wide range of topics including Raspberry Pi 6, Zero-series shortages, AI, industrial adoption, and the future of the RP2040 ecosystem. Here are some of the most important announcements and… |

A Homemade Approach to Long-Range Night Vision Most infrared night-vision systems are limited to relatively short distances mainly because standard IR LEDs spread light too widely to be effective over long ranges. Curious about the practical limits of infrared imaging, the independent engineering channel Project 326 developed a custom-built system aimed at long-range nighttime observation. The system combined a modified low cost… |

ESP32 Speech-to-Text using Wit.ai In this project, we’ll be learning how to build an ESP32 Speech to Text system using an ESP32 development board. We’ll use an I2S MIC to record speech and an OLED display to display the converted text. In addition to the display, the text will also appear in the serial monitor. Since ESP32 cannot run a Speech recognition model locally due to its hardware… |

Smart WLED Clock with RTC, PIR, Audio feedback and Environmental Monitoring The integration of addressable LEDs with the WLED firmware has revolutionized DIY lighting projects, allowing for complex visual effects with minimal to no coding. However, most standard WLED-based clocks face significant limitations, such as time-drift during internet outages and continuous power consumption regardless of room occupancy and no alarms. To address these issues, this… |

Clock Uses Water Bottles as Pixels With Membrane Pumps and Servos Maker Strange Inventions has built a water-based digital clock in which 60 small bottles act as individual pixels, collectively forming numerals to display the time. The bottles, sourced at 10 cents each, brought the total project cost to approximately $580. Each bottle is filled or emptied with dyed water to switch its pixel state on or off, with the display controlled by a microcontroller… |

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… |

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… |
