A community project called MimiClaw has released software that lets an AI assistant run on ESP32-S3 microcontroller boards and respond to commands sent via the Telegram messaging app. The system acts as an intermediary between user messages and an online language model, enabling both conversational responses and hardware control functions such as GPIO, sensors, and actuators.

YouTuber EastMakes set out to build something, a true RGB 14-segment display module. Wanting a retro alphanumeric display style for a large LED message board project, he designed his own module using ultra-tiny SK6805 addressable LEDs measuring just 1.5 mm square. Since datasheets lacked precise placement references, he scanned a physical display and calibrated the image in CAD software to…
Open-source personal AI assistants such as OpenClaw have shown how task automation can be integrated with everyday chat platforms, but they usually assume desktop- or server-class hardware. PicoClaw, a new project from Sipeed, targets a different class of devices by focusing on very low memory usage and simple deployment on small Linux boards. It is positioned as a lightweight alternative for…
A YouTube channel named The Amazing PhD has presented an engineering project that showcases the development of a wrist-mounted grappling hook system, a compact mechanical device inspired by fictional gadgets but implemented using real-world engineering principles. In the video, the creator documents the complete design and development process, explaining how the system integrates a projectile…
What if a small sensor could understand space in three dimensions? A maker recently showed how a Time-of-Flight (ToF) sensor can be turned into a basic 3D scanner. The sensor sends out infrared light and measures how long it takes to return, a method known as time-of-flight distance measurement. By using a multi-zone depth array, it captures several distance readings at the same time, creating…
A recent video by Axiometa explores an unusual electronics challenge: driving addressable NeoPixel LEDs entirely in hardware, without any microcontroller or code. Since WS2812-style LEDs normally rely on tightly timed digital data from MCUs, the project asks whether basic components like counters, timers, and logic gates can replicate the protocol. The goal was to generate the required pulse…
The nRF9151 MicroMod Processor is a compact cellular IoT module built around Nordic Semiconductor’s nRF9151 System-in-Package (SiP) and designed to work seamlessly with SparkFun’s MicroMod ecosystem. Using an M.2 E-Key connector, the 22 × 22 mm board plugs directly into compatible MicroMod carrier boards, making it easy to add cellular and positioning capabilities without complex wiring or…
A creative maker has developed an impressive self-playing chessboard that can automatically move pieces using magnets and detect their positions. The board is equipped with magnetic sensors beneath each square, while each chess piece has a small magnet on its base, allowing the system to precisely track every piece. An ESP32 microcontroller is part of the setup, handling some hardware…
A maker has completed and demonstrated a remote-controlled bionic butterfly, sharing the build process in a recent online video. The project involved assembling a lightweight artificial butterfly with flapping wings driven by remote control components. Viewers were shown the step-by-step construction, including key mechanical and electronic elements of the flyer.
According to the video…
YouTuber Coding with Lewis recently demonstrated how an AI model can be given a physical body by converting an RC car into a fully autonomous wilderness explorer. Using Claude 3.5 Opus as the decision-making engine and a Raspberry Pi 5 as the onboard controller, the project bridges digital intelligence with real-world robotics, allowing the vehicle to navigate snowy forest terrain completely…
Thermal imaging drones are no longer limited to military or industrial use. A YouTuber named Hoarder Sam demonstrates how a thermal drone can be built at a relatively low cost, opening the door for hobbyists, students, and innovators to explore heat-based vision technology. The project highlights how modern sensors and compact electronics are making advanced imaging tools more accessible than…
Espressif has unveiled the ESP32-E22, the company’s first Wi-Fi 6E system-on-chip and the start of a new lineup focused on high-performance wireless connectivity. Designed as a radio co-processor (RCP), the device handles Wi-Fi and Bluetooth tasks independently, allowing the main host processor to concentrate on application logic rather than networking overhead. The…
