    GoFly has an agent design, order and test an STM32F405 flight controller

    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.

    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.

    Session Beacon: a USB status light for parallel Claude Code sessions

    Session Beacon shows every Claude Code session on a 1.8-inch ST7735 screen and turns a row red when that session waits on a prompt. A Python daemon fed by Claude Code hooks sends updates over USB serial to an Arduino Nano ESP32 or a Waveshare RP2040-Zero. Setup is documented for Windows only. README photos show the finished beacon.

    Claude Code identifies three unlabeled ESP32 boards and writes firmware for each

    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.

    Claude Code ports a BBC Micro emulator to the Adafruit Fruit Jam

    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.

    Iluvatar Labs' research agent routes AgentPad13, a $35 Codex Micro clone

    Iluvatar Labs had its research agent, Marvin, route AgentPad13, a two-layer RP2040 macropad modeled on OpenAI's Codex Micro. Marvin reached zero unrouted connections and zero DRC errors; FreeRouting and Quilter had left 18 and 19 unrouted. It also built and simulated the QMK firmware. Photos show the lit prototype.

    Tiny2040 voice player built with Copilot and Antigravity, no hand-written code

    The author of a dev.to post built a MicroPython voice-announcement player on a Pimoroni Tiny2040 with a MAX98357A amplifier without editing code by hand. GitHub Copilot wrote it until it looped on out-of-memory errors, and Google Antigravity fixed the storage problem. The post says the agent reported all tests passing while a playback-speed change had no effect.

    OpenMicroKbd: an agent-written CoHDL schematic becomes a working Codex Micro-style macropad

    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.

    Adsum IoT Coder finds a disabled RF front-end with a BLE sniffer it flashed itself

    Adsum Networks' IoT Coder agent debugged a Fanstel BWG840 gateway whose nRF52840 BLE scanner ran cleanly but received nothing. It flashed an nRF52840 dongle as a Bluetooth sniffer and compared the air with RTT logs: 36 advertisements captured, none received. The cause was an RF front-end that was never enabled. This is a vendor demo of its own product.

    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.

    Claude Code agents build a tilt maze game on a PIC24 Curiosity board and debug its I2C driver

    Ori Grossman built a tilt maze game on a PIC24FJ256GA705 Curiosity board with Claude Code agents, an ADXL345 accelerometer and a 96x96 OLED. One agent drove the board's debugger through MPLAB's mdb command line and traced an I2C driver bug that dropped queued bytes. The README has a photo of the game running.

    Programming the Fri3d Camp 2024 badge with Claude Code

    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.

    Claude revives a bricked Kawai CA49 piano by writing a Bluetooth firmware flasher

    A Hacker News commenter says Claude revived a Kawai CA49 digital piano bricked by the wrong update file. Claude decompiled Kawai's Android app, found the hardcoded firmware key, decrypted the update and wrote a script that reflashed the piano over Bluetooth from a laptop. The commenter says it took about an hour and shares no code or logs.

    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.

    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.
