Show HN: Arcaide – Explore code with multi-level call graphs
One of the things I do when approaching a new codebase is to find the entry points and start exploring down the call paths. This gives a good overview of the different components in the code and how they're connected. I wanted to translate that to a visual experience, similar to how you would use call graphs, but there's a couple of problems with classical call graphs. One, call graphs represent flow at the function level, so the architectural context is lost. And call graphs tend to get very la

LED Strip Tetris: Zero-Code Hardware Game with TuyaOpen + Claude Code Tutorial
I built an LED Strip Tetris game — without writing a single line of code. No keyboard mashing. No debugging at 2 AM. No reading 500 pages of datasheets. Just natural language prompts, an AI agent, and a Tuya T5 AI Core board. Here's the full breakdown of how it works 👇 🧩 What Is LED Strip Tetris? LED Strip Tetris is a DIY hardware game built entirely through natural language prompts using TuyaOpen IDE and Claude Code. It runs on a Tuya T5 AI Core development board with a WS2812 LED strip (72 LEDs) and three color-matched buttons — red, green, and blue. Colored LEDs fall from the top of the strip; players press the matching button to shoot a colored LED upward and eliminate the falling one on contact. The entire game — firmware, game logic, hardware wiring, sound effects, compilation, and flashing — was generated by AI. Zero manual coding. 🔌 The Hardware (Ridiculously Simple) Component Role Tuya T5 AI Core Board Main MCU — runs game logic, drives LED strip and buttons WS2812 LED Strip (72 LEDs) Display — colored LEDs fall and get eliminated 3 Push Buttons (Red / Green / Blue) Input — shoot matching color upward to clear falling LEDs Speaker Sound effects on button press That's it. No custom PCB. No complex wiring harness. Just four components plugged into a dev board. 🤔 Why This Is a Big Deal Here's what building a hardware game normally looks like: Step Traditional Approach Vibe Coding with TuyaOpen IDE Dev environment setup Install toolchain, configure SDK, fight dependencies Copy a workflow link, paste into Claude Code, click confirm Game logic Write C code from scratch, design state machines Describe the game in one sentence, AI generates the code Hardware config Read datasheets, look up GPIO mappings, manually configure Tell AI which pins you're using, it handles the rest Sound effects Write audio decoding code, integrate codecs Give AI the file path, it decodes and compiles Debugging Serial logs, oscilloscope, hours of trial and error AI self-diagnoses compile
