    instr-core: a safety layer between AI agents and SCPI instruments

    instr-core checks each SCPI command an agent plans against the instrument's schema and dry-runs the plan before anything touches hardware. Checks cover ranges, compliance settings, output state and command order, and real VISA runs need explicit confirmation. The first workflows are IV sweeps on a Keithley 2600, one paired with a DMM6500. The README shows no measurements.

    TopicForge: a read-only MCP server for inspecting ROS 2 and DDS

    TopicForge gives an agent 15 read-only MCP tools for a ROS 2 graph, rosbag files and DDS discovery traffic. The code has no write path to the robot. In the README's example it finds a best-effort publisher facing a reliable subscriber. CI runs it against a ROS 2 Humble and Jazzy test bench; no physical robot is shown.

    camclave captures single still frames from a webcam for Claude Code or Codex, and only while a red on-screen window shows the camera is on. The agent can read a multimeter, check whether an LED is lit or watch a 3D print's first layer. Stopping the session deletes the captures. The 17-second demo shows the agent reading 4.96 V DC.

    Clawdmeter: an ESP32 desk display for Claude Code usage and alerts

    Clawdmeter shows Claude Code session and weekly usage limits on an ESP32 display board, where a Clawd character reacts to prompts. Through Claude Code hooks it flags sessions waiting for input. It pairs over Bluetooth, and its buttons send key presses. The README lists 8 supported boards and 15 community ports. A photo shows two devices running.

    Agent-built Zephyr firmware and host tools for the Waveshare RP2350 relay board

    rp2350-relay-6ch drives the six relays of a Waveshare RP2350-Relay-6CH board from Zephyr firmware, with a custom MCUmgr management group over USB CDC. Host tools include a Python RPC library, a CLI and a Linux daemon for test rigs. The author describes it as a first agentic coding project; the README has product photos only.

    Gemini CLI and Claude Code in mechatronics: a guest lecture with Teensy demos

    Parsa Ghasemi published the slides and demo prompts from a guest lecture to mechanical engineering students at Cal Poly Pomona. It covers installing Gemini CLI and Claude Code, writing prompts for runnable embedded code and catching wrong pins, invented library calls and unit errors. The live demo codes a PID position controller for a Teensy 4.1. We found no recording.

    Espressif on Code with Claude: Cardputers, Claude Code and Desktop Buddy

    Espressif published a recap on 14 May of ESP32 projects from Anthropic's Code with Claude event, where each attendee got an ESP32-S3 M5Stack Cardputer. Attendees described a program in plain language, and Claude Code wrote and flashed it. The post also covers Claude Desktop Buddy, a BLE reference design on the M5StickC Plus, and Espressif's own ESP Desktop Buddy library.
