Christian 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.

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.

Creator Magic plugged three unlabeled ESP32 boards into a Mac one at a time and had Claude Code identify each over USB. Claude then wrote different firmware for each: a sea-conditions display, a Bluetooth audio spectrum analyzer and an e-paper sound picture. The 23-minute video shows all three running and a display offset Claude diagnosed from a photo.

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.

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.

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.

CODEX KEYBORED is a parody of the Codex Micro macropad, designed through prompts alone from Fusion 360 mechanics to a six-layer KiCad board. The repository adds STM32F072 USB HID firmware, a factory test and JLC quotes captured on 17 July. The README does not name the agent, and says no fabricated board has been brought up.

David Steeman used Claude Code to reverse-engineer and program the Fri3d Camp 2024 badge, an ESP32-S3 handheld with an LCD. Claude backed up the flash in ROM mode, worked out the OTA boot scheme and wrote a serial upload tool. Steeman says the app launcher and name badge it built ran on the device. The photos show only the hardware.

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.

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.
