A $5 ESP32-P4 Chip Now Writes Down Everything You Say, Live and Offline, With About 4 Wrong Words in 100 Speech recognition on a microcontroller usually means a short list of fixed commands. Boumedine Billal has gone much further: his open-source project runs a full speech-to-text model live on an ESP32-P4, a chip that costs about $5. You talk into the board's microphone and any English sentence appears on its screen as you speak, with no Wi-Fi, no cloud and no neural accelerator. On the standard… |

DOOM on a $30 FNIRSI Clamp Meter: 32 KB of RAM, No Framebuffer and a Steady 29 fps Running DOOM on odd hardware is an old tradition, but Artur Bieniek has picked one of the tightest targets yet: the FNIRSI DMC-100, a budget clamp meter built around an Artery AT32F415 microcontroller with just 32 KB of RAM. His open-source port of doomgeneric plays the whole first episode of Freedoom on the meter's 320x240 colour screen, with sound effects on the buzzer, and it averages 29… |

A 2011 Nokia E6 Now Boots Linux 6.12 and Runs Wayland, and It No Longer Reboots Every Four Minutes The Nokia E6, the 2011 Symbian business phone with a QWERTY keypad and a 640x480 touchscreen, is getting a second life as a Linux machine. Developer fluffleswaffles has brought up Linux 6.12 on it. The project's milestone log starts with a first boot to a BusyBox shell on 13 October, and the kernel now drives the phone's own display, runs the Wayland compositor weston with the foot terminal,… |

ESP32-S3 3D Scanner Brings Budget Space Carving and 3D Mesh Generation to Embedded Hardware Projects A recent project shared on reddit - r/esp32 showcases how much computer vision potential can be squeezed out of inexpensive, low-power hardware. Built around a Seeed Studio XIAO ESP32-S3 board paired with its dedicated round screen extension, the handheld device doubles as a self-contained 3D object scanner. Originally intended as a platform for an augmented reality game, the creator pivoted… |

Maker Builds an Offline Wikipedia Using an ESP32 Board and Its Built-In microSD Card Slot to Store Data Alun Morris’s Offline-Wikipedia using ESP32 is an open-source project that turns the inexpensive ESP32-2432S028, commonly called the “Cheap Yellow Display” or CYD, into a standalone Wikipedia reader. The hardware combines an ESP32 microcontroller with a 320×240 ILI9341 color display, an XPT2046 touchscreen, and a microSD card interface. Instead of depending on Wi-Fi or cloud services, the… |

This ESP32-P4 Turns a DJ Controller Into a Laptop-Free DJ System With Two Music Decks and Audio Mixing A maker has built a standalone DJ system using the ESP32-P4, allowing a Pioneer DDJ-FLX4 DJ controller to work without a laptop running DJ software. The open-source Pajoniiir project uses a Guition JC4880P443C_I_W board with an ESP32-P4 and 4.3-inch touchscreen. It reads music from a USB drive exported from Rekordbox and supports MP3, WAV and FLAC files. The system can run two DJ decks at the… |

A Solo Dev Built an OS for ESP32 Boards and Gave Its JavaScript Engine Direct Access to the Hardware An open-source project called KryonOS is a GUI operating system for ESP32 microcontroller boards, built for use with a touch display and an SD card module. Built by a single developer who goes by Haris (GitHub handle Haris16-code) and released under the GPL-3.0 license, it adds a real touchscreen interface, a file explorer, and an app store to hardware that normally runs just one fixed program… |

Jurassic Park's Legendary Dinosaur Input Device Recreated Using Modern Technology Long before today's advanced motion capture systems became commonplace, Industrial Light & Magic (ILM) developed an ingenious hardware solution known as the Dinosaur Input Device (DID) for Jurassic Park. Instead of animating dinosaurs frame by frame with a mouse, animators manipulated a physical dinosaur puppet embedded with magnetic rotary encoders at every… |

How to Build an Interactive Robotic Arm using PIC Microcontroller? Robotic arms are widely used in industrial automation, research, and educational projects. Building and controlling one is a great way to learn the fundamentals of embedded systems, motion control, and robotics. In this project, we will design and build a 4-degree-of-freedom (4-DOF) robotic arm controlled… |

Two-Way Holographic Display with Wemos D1 Mini This display can show two different images at the same time - no VR headsets, no software tricks, just pure optics. This is a two-way holographic display made by Julius Makes. The whole idea is that two players, sitting opposite to each other, should see the mystery instructions meant for the other person. Plus, they should be able to see their faces through the… |
