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.

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. The README links a YouTube Short of the panels on his desk.

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.

StackChan Remote MCP connects Codex to an M5Stack CoreS3 StackChan robot through a FastMCP server and an MQTT broker on a VPS. Codex switches the robot's expression, gets camera photos back as MCP images and reads screen and head-pad touches from an unread queue. The README reports an end-to-end test on a CoreS3 but shows no photos or logs.

Dimitri Sudomoin spent an afternoon with Claude Code finding the handshake a FlexiSpot E7 Pro Plus controller expects from its keypad. A $7 ESP32 now imitates the keypad so Home Assistant can move the desk. Claude Code also mapped a Plaud Note recorder's Bluetooth protocol over about 5 days. He writes that the models are about 90% accurate.

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.

Claude Code drives a Freenove 4WD mecanum car on a Raspberry Pi Pico W through an MCP server and plain-text TCP commands. In one session it reversed until the ultrasonic sensor read 6 cm, then swept the sensor from 20 to 140 degrees and plotted the distances. The repo has photos, terminal captures and clips from live sessions.

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.

Marcel Dütscher and his 10-year-old son built Pixel Pets, virtual pets for three M5Stack boards, with Claude writing the firmware under their direction. The CoreS3 version adds voice control through M5Stack's Module LLM, and pets swap gifts over ESP-NOW. Photos, a 10-second clip and a two-minute reel show the pets running on the devices.
