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…
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, 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…
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…
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…
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…
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…
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…
As appliance and equipment manufacturers look for ways to reduce system costs, many are replacing displays with Human Machine Interfaces (HMIs) using high-end decoration and illuminated capacitive-touch buttons, sliders and wheels. These interfaces often require a large number of touch sensors which can increase acquisition time and reduce the signal-to-noise ratio (SNR) when using…
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.…
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…
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…
