news.ycombinator.com Chris Greening 2025-07-30 08:47:26

After "vibe coding" a software-based vibing button in my last video, I decided to take things one step further: vibe-coding the actual hardware. The challenge? Let AI design a working ESP32-S3 development board, from scratch. Tools of the Trade For this experiment, I used Atopile — a tool that lets you define a hardware project using code and turns it into a KiCad PCB. I also enlisted Claude, an AI coding assistant that seemed to outperform Cursor for this task. The Prompt The board needed t

International Space Station Tracker SpaceStationTracker is an application that displays the current position of the International Space Station on a 2D world map. It runs on a ESP32-2432S028R ILI9341 device with a 2.8" screen, commonly known as the CYD "Cheap Yellow Display", which costs $20 or less. The code was written using Arduino IDE / ESP32 development environment in c++. I used this project to learn programming for ESP32/Arduino/CYD. It includes topics such as graphics using LVGL, wifi

As of this writing, it's around $15 at JacobsParts and around $7 from AliExpress. There aren't a ton of ESP32 boards with Ethernet, and the WT32-ETH01 is by far the smallest, cheapest, and simplest. (The OLIMEX ESP32-POE and wESP32 are the other notable options.) So,
