ESP32-S3 E-Paper Board Runs a Game Boy Emulator at 30 FPS. It Barely Hit 2 FPS Before a Custom-Built Driver A developer who goes by kuslota has released InkBoy, a custom display driver and firmware that runs a Game Boy emulator at around 30 frames per second on Waveshare’s ESP32-S3-ePaper-1.54 V2 board. Waveshare specifies about 300 ms for a partial refresh on the board’s 200x200 panel, and the stock driver managed barely 2 fps in the developer’s testing. The code is on GitHub under an MIT license… |

This ESP32-C5 Picks Up India’s NavIC Satellite Signal Using Its Built-In 2.4 GHz Radio, in Early Test The open-source snappnt project, developed by h-shiono, explores whether an affordable ESP32 board can detect signals from India’s NavIC satellite navigation system. NavIC is used for satellite-based navigation, but this project does not work like a normal GPS tracker. Instead, it captures very short samples of radio signals and uses software to search for a known satellite signal pattern.… |

SignalSweep: Open-Source BLE and Wi-Fi Scanner on ESP32-C5 That Can Detect AirTags, Flock Cameras and Drones SignalSweep, an open-source project published on GitHub by a developer using the handle B0z0dcl0wn, turns a Seeed Studio XIAO ESP32-C5 into a pocket-sized scanner for trackers, surveillance hardware and drones. It is licensed GPL-3.0-or-later. The C5 is the main target because it can listen to both 2.4 GHz and 5 GHz Wi-Fi alongside Bluetooth LE, and the developer argues that more cameras and… |

Instead of Training a Robot, He Let a General-Purpose Multimodal LLM Control It to Pick Up and Bin a Toy Harrison Kinsley, the YouTuber behind Sentdex, has shown a Vulcan Robotics Sourccey, a 3D-printed robot he calls “Chonk,” picking up a toy from the floor and dropping it in a bin with no task-specific training. In part three of his “Everything is LLM” series, published Oct 8, a general-purpose multimodal language model made the task decisions. The planning and control came from DeepSeek’s V4.1… |

This Raspberry Pi Zero 2 W Runs a Virtual Viking Dragon That Feeds on Nearby Wi-Fi and Bluetooth signals What if your virtual pet could find food from the Wi-Fi and Bluetooth signals around you? Meet Harald, a virtual dragon created by a Raspberry Pi enthusiast. Built using a Raspberry Pi Zero 2 W and a Waveshare V4 e-paper display, Harald treats nearby Wi-Fi networks and Bluetooth devices as food. Discovering new devices makes the dragon happier, turning everyday wireless activity into a virtual… |

This DIY ESP32-S3 Wi-Fi Sensing System Detects People and Tracks Movements Without a Camera at 80% Accuracy Better Stack from Youtube recently used an open-source project called RuView and explored how Wi-Fi signals can be used to detect human presence and movements without relying on a camera. He describes how Wi-Fi signals change as he travels through a room and bounce off walls, furniture, and people. When someone moves, their body alters the signal's strength and phase across different frequency… |

This DIY Video Converter Uses an RP2350 to Turn Vintage TTL RGB Signals Into DVI-Compatible Video Before VGA became common, many computers used TTL RGB video to send digital colour signals to their monitors. Today, finding a compatible monitor for this older hardware can be difficult, making it harder to use and restore vintage computers. A new DIY project by Charlysan offers a solution with an RP2350-based TTL RGB to DVI converter. It captures the video output from older computer hardware… |

The Negotiator II: A PCB Business Card Built to Unlock 48V Power Delivery From Any USB-C Charger Electronics and mechanical engineer Anas Malas has redefined networking hardware with The Negotiator II, a smart printed circuit board (PCB) business card that doubles as a portable USB Power Delivery (USB PD 3.1) lab power supply. Measuring just 2 mm thick, the wallet-sized card features nearly 200 surface-mount LEDs, dual USB-C ports, and live telemetry displays for voltage, current, and… |

This $2 ESP32-C3 Uses Flash Storage to Build a DNS Ad Blocker for 140,000+ Domains With Just 50 KB RAM The ESP32-C3 AdBlock is an open-source project that turns a low-cost ESP32-C3 microcontroller into a DNS-based ad blocker and tracker system. DNS helps devices find the IP addresses of websites and online services. This project checks DNS requests against a blocklist of known advertising and tracking domains. If a domain is blocked, the ESP32-C3 returns 0.0.0.0 instead of its real IP address.… |

Maker Built a DIY ESP32 Security Camera With a Picture Frame Display and Shared the Custom Firmware Building a custom, low-cost home security setup no longer requires expensive commercial hardware or subscription fees. Using two inexpensive ESP32 microcontroller boards, HVT Lab and Huy Vector from Youtube recently built a fully functional, self-contained wireless video surveillance system. The setup features a dedicated ESP32-CAM module mounted at an entry point such as a front gate which… |

This Open-Source 68008 DIY Computer Runs CP/M-68K BASIC and Custom Programs Using a 3-IC Lite Design The 68k-MBC is a homebrew single-board computer built around the Motorola 68008 processor, running at 8 MHz. What makes it interesting is that it can be built in two versions, Lite and Full. The Lite version keeps the hardware very simple, using three main ICs: the 68008 CPU, a PIC18F47Q10 microcontroller, and SRAM. It supports 128 KB or 512 KB of RAM and can run CP/M-68K. The Full version… |

This STM32N6 Turns Speech Into Text Offline Using Its NPU and a 7.2M-Parameter ASR Model The STM32N6 is being used to run an offline speech recognition system that can turn spoken English into text without a network connection. The project runs on the STM32N6570-DK, using its onboard microphone to capture speech and its display to show the recognized words. This system is designed to recognize different English words. At the core is the STM32N6's Arm Cortex-M55 and its ST Neural-… |
