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.

Tal Raviv connected Claude to a SunFounder PiCar-X through a terminal on its Raspberry Pi, with camera photos as feedback. The robot saved notes, learned gentler turns and a three-point turn, and spent about 15 minutes parking at a filing cabinet instead of 20 cm from the door. The post embeds an edited demo video.

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.

Amer El-Saad built a 3-DOF tower crane for his master's thesis that Claude plans and drives through 4 MCP tools. One overhead camera, YOLOv8 and ArUco markers locate parts and stations in centimeters. An Arduino Uno drives the DC motors, and code rejects any route that crosses a worker. README photos show the crane and live detections.

Cliff Lasser built a clock from 128 Soviet IV-25 VFD tubes on eight boards, each run by an Arduino Nano ESP32 over RS485. He wrote about 15 pages of specification, and Claude wrote all the code, now over 8,000 lines. The first version, about 3,500 lines, ran on the first try with one bug: the display was rotated 180 degrees.

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.

Dimdim had Gemini 3.1 Pro write the Verilog for an audio reclocker on a MAX 10 10M08 board. He pasted code from the chat into Quartus. The design passes I2S through a dual-clock FIFO, adds DSD and S/PDIF input and buffers in PSRAM. Gemini, Claude Sonnet 4.6 and Claude Opus 4.7 all failed to make a PRBS-15 test work.

Clem Delangue, CEO of Hugging Face, wrote his first app for the Reachy Mini desktop robot with Claude in under an hour. He published it as a Hugging Face Space that runs on a Reachy Mini or in simulation. The post includes a short video; we could not confirm it shows the physical robot.

Hackaday covered a Ready Z80 video in which the creator guides Claude, section by section, to write Wordle in Z80 assembly for a TEC-1G. The board has a QWERTY keyboard add-on, but Claude first assumed a hex keypad and used instructions the Z80 does not have. It stopped once corrected. Hackaday says the two got a working game.
