Curator pick: Christian Schaller uses Claude Code to reverse engineer a film scanner and a laptop cameraChristian Schaller had Claude Code write a SANE backend for a Plustek OpticFilm 8200i scanner from USB captures of its Windows driver in a VM. He then reused the method to fix the kernel driver and libcamera for the IMX471 camera in his ThinkPad X1 Carbon. The post shows scans and before-and-after camera frames.
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.
ESP32 iPhone Agent runs on an ESP32-S3 that presents itself to an iPhone as an AirPlay receiver, a USB mouse and a USB keyboard. A vision model watches the mirrored screen and taps, swipes and types through AssistiveTouch on an unmodified phone. README photos show the board and phone setting a repeating alarm in the Clock app.
Andreas Spiess's 18-minute video shows Claude Code taking ESP32 firmware from a written specification to passing tests on a Raspberry Pi testbench. The agent writes and builds the firmware, flashes it to boards on the bench, runs tests over Wi-Fi, MQTT, BLE and RF, and fixes failures until the tests pass. The skills and testbench code are open source.
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.

Felipe Sens Bonetto used AI agents to write openTPU, an LLM inference accelerator with its own instruction set, simulator, compiler and host software. On an Inspur PCIe card with a Xilinx Kintex-7 and 2 DDR3 channels it runs 10 models, including Qwen3 and Gemma 4, with their real weights. A README GIF shows the chat demo running on the card.

Munetomo Maruyama had Claude Code design mmRISC-2, a 64-bit RV64GC RISC-V core, and brought it up on a Digilent Arty A7-100T. Claude wrote the specification, SystemVerilog RTL, testbenches and documents; Maruyama ran Vivado and the board. Bring-up logs in the repository record Linux 7.2 booting to a shell at 50 MHz and a 120-minute stress test passing.

GoFly says an AI agent designed a six-layer STM32F405 flight controller in EasyEDA Pro through easyeda-agent, then ordered it from JLCPCB with SMT assembly. The post says the agent then flashed the board over USB and ran basic function tests. The design keeps only the MCU, gyroscope and accelerometer, and testing stayed on the desk.

A Reddit user had Claude Fable 5 design an RP2350 e-ink board through a KiCad MCP server, allowing no manual edits. Wccftech reports several rounds to fix wrong part picks. Five assembled boards cost 130 euros plus $450 in API credits, and Claude Opus 5 wrote the firmware. Photos show the board driving its 1.54-inch display.

Tide & Wind Tracker shows tides and wind on an M5Stack PaperColor and tests its e-paper rendering on the ESP32-S3 itself. Test firmware renders fixtures sent over USB and returns the canvas bytes for comparison with golden images. Claude Code iterated against those tests while a person approved every change. The README has a photo of it running.

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.

JLCPCB's guide shows Claude Code designing a 5 A XL4015 buck converter in KiCad 10 through the kicad-mcp-pro server. Claude built a 16-net schematic and routed a 63 by 33 mm board with an A* router it wrote in Python. A netlist check caught an ISENSE to ISET short that ERC only warned about. The guide says nothing was fabricated.

Andrew de Quincey had Claude Code port the Frank Micro BBC Micro emulator to the RP2350-based Adafruit Fruit Jam. Claude studied the codebase, planned around clock and PIO conflicts and wrote a script for the audio codec registers. Photos show the emulator booted over HDMI. It ran Exile, and an odd Mac keyboard was the only snag.

A JLCPCB blog author had Claude Code with Opus 5.5 rebuild a CH32V006 component tester in EasyEDA Pro from a PDF schematic. Working through a local API bridge, Claude swapped 8 out-of-stock parts, placed 47 parts and routed the 2-layer board with Freerouting to zero DRC errors. The post says the board was not fabricated or visually reviewed.

bench-mcp exposes SCPI power supplies, multimeters and oscilloscopes to an agent through 10 MCP tools, with no tool that sends raw SCPI. Voltage and current limits come from a file a person signs off, read once at start-up and enforced by a pure function before every command. The README says it has run only against simulated instruments.

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.

Tiny Engineer is an open-source desk robot that acts out a coding agent's work. It looks around while files are read, types while code is written and rings a bell when the task ends. An ESP32-C3 on an open KiCad control board drives five SG90 servos and an OLED face. The README links a demo video and build photos.

Tramuntana is an open bench tool built on the RP2350 (Raspberry Pi Pico 2) and Zephyr that works over one USB cable. It has SPI and I2C master and sniffer modes, a 2-channel 500 kS/s scope, a waveform generator, an 8-channel logic analyzer and a UART bridge. Its Python package adds an MCP server. The README shows no captures.

AWIC controls FX2-based USB logic analyzers and oscilloscopes that sigrok supports, from a Rust server with native USB drivers. Agents reach it through MCP, people through a web UI and scripts through an SCPI socket; it also switches USB hub port power. It runs on Linux and was built with Claude Code. The README says every feature works on hardware.

Tony Huang built OpenMicroKbd, an open recreation of OpenAI's Codex Micro macropad on an STM32F072, whose schematic an AI agent wrote in CoHDL. Quilter.ai did the layout, an agent helped with the Rust firmware, and Huang had the boards fabbed and finished the assembly by hand. The launch post has photos of the assembled board and printed case.
