    HeyPCB MCP: design KiCad boards from Claude Code, Codex or Cursor

    HeyPCB's MCP server connects Claude Code, Codex or Cursor to its hosted KiCad board-design service. An agent can ask HeyPCB to build the whole board with build_board, or add parts and connections itself and call check_board until each finding is fixed. A local npm package adds KiCad project upload and Gerber export. The vendor README shows no fabricated board.

    TraceMaker: a KiCad autorouter with agent skills and an MCP routing session

    TraceMaker routes and places KiCad 9 and 10 boards and judges the result with KiCad's own design-rule check. Two agent skills prepare a board and sign off a route, and an experimental session mode exposes the router over MCP. The README reports 72.5% of PCBench tier B boards routed with no added KiCad errors, against 50% for Freerouting.

    OpenBaud: serial devices as audited, replayable tools for coding agents

    OpenBaud connects Codex to local serial devices through an MCP server and plugin, with every write audited. It identifies ports from USB metadata, checks framing and checksums, and asks for acknowledgment before dangerous commands. Each byte goes to a capture that replays without hardware. The demo GIF and 46-second video show it on an ESP32-S3.

    debug-devices: phone camera, webcam multimeter and boardview tools for repair agents

    debug-devices connects coding agents such as Claude Code and Codex to a repair bench through an MCP server. The agent drives an Android phone camera with zoom and torch, reads a multimeter through a webcam and a vision model, and finds parts, nets and test points in the board's boardview file. The README's clip shows the monitor page only.

    BenchPod plugins put an EmbeddedCI hardware-in-the-loop bench behind Claude and Codex

    EmbeddedCI's BenchPod plugins connect Claude Code and Codex to a BenchPod, the company's hardware-in-the-loop tester wired to the board under test. One MCP server has tools to flash over SWD, power-cycle and capture the boot log, emulate I2C sensors, capture logic and analog signals and talk CAN. The vendor README lists the tools but shows no runs.

    An AI agent on a Nokia 110 4G, built by reverse engineering its firmware with Codex

    Anup Ray reverse-engineered a Nokia 110 4G's firmware with OpenAI Codex and rewrote its Calculator app as an agent chat app. It sends messages to DeepSeek over the phone's SIM data and can check the battery, toggle the torch, place calls and set alarms. It loads into RAM from a computer, so a restart removes it.

    ESP-Mosaico: an ESP32-S31 modular devkit built for coding agents

    CNX Software reported on 21 October that Espressif sells ESP-Mosaico, a modular ESP32-S31 kit with a square touchscreen, for $59 on its own store. Espressif's Vibe Coding guide has a coding agent such as Codex build apps from the esp-mosaico-vibe workspace and install them over USB. An on-board agent, ESP-Claw, answers chat requests.

    AA-Robotics benchmark has coding agents drive a real robot arm

    Artificial Analysis launched AA-Robotics v0.1, a benchmark in which language models in coding-agent harnesses control a Hiwonder NexArm robot arm. Models in Codex, Claude Code and Antigravity write code for 8 zero-shot tabletop tasks, watching through 4 cameras. GPT-6 Astra led with 69.4 and Claude Opus 5.5 scored 48.8. Models took about 30 minutes a task; people averaged 20 seconds.

    A Wired reporter gives his OpenClaw agent a LeRobot SO-101 arm

    Wired's Will Knight connected OpenClaw and Codex to a LeRobot SO-101 arm with a camera. Codex configured the connections, helped calibrate the joints and wrote a script that grips a red ball the camera sees. OpenClaw then guided training of a control model, checking its error rate after each run. The article's clips show the arm at work.

    Using AI agents in VS Code to build, test and debug STM32 firmware

    Tech-AD-venture's 23-minute video walks through using AI agents in VS Code for STM32 firmware, contrasting autocomplete with task-based agents. Tools covered include GitHub Copilot, Claude, Codex and PlatformIO. An STM32 RTOS example runs from requirement to review. Its description lists MCP hardware access as a possibility; we could not confirm on-board debugging in the video.

    Niclas Vestlund's VibePulse shows Claude Code and Codex usage and agent activity on a Waveshare ESP32-S3 AMOLED panel. A full-screen alert appears when an agent waits for input, and a tap answers supported prompts. A Python service runs on macOS or Windows; cloud relays are off by default.

    co-arm: a 3D-printed four-joint camera arm that Codex can see through and move

    co-arm is a 3D-printed four-joint camera arm built from ST3215 serial-bus servos, an ESP32 servo HAT and a Raspberry Pi 4. Codex previews each move before running it, then reads the joints and camera to check the result. The author says Codex has moved the physical arm; demo media is not published yet. The software is source-available for noncommercial use.

    code-chan: coding-agent status and permission prompts on an M5Stack CoreS3

    code-chan runs on a Stack-chan robot with an M5Stack CoreS3 and shows whether Claude Code or Codex is ready, working or waiting for permission. The user approves or rejects a prompt on its touchscreen. A local Node.js bridge sends hook events over USB serial, and the firmware checks each message before acting. README photos show three states.

    A software engineer had Codex with GPT-5.5 write most of wfb-link, a Rust stack that drives an ALFA AWUS036ACH Wi-Fi adapter from macOS userspace. Claude Opus 4.7 helped at times. The stack initializes the RTL8812AU and sends and receives WFB-NG frames, with a Raspberry Pi 5 at the far end. The Show HN post says the alpha took two weeks.

    Codex builds an LVGL speedometer dashboard on a bare LilyGo T-Display S3

    Craig Hollabaugh had Codex identify a blank LilyGo T-Display S3, install the toolchain and write a display test in an unedited session. When the screen stayed dark, the agent found the panel is an ST7789 on an 8-bit parallel bus and rewrote its driver. It then built an LVGL 9.2 speedometer and tachometer dashboard, on camera throughout.
