Controller Tester
Test controller drift, circularity and deadzones
What it does
A free web-based tool to diagnose gaming controllers without installing software. It provides instant visual feedback for joystick performance, including: Stick Drift Testing: Measure drift magnitude to see if your sticks move on their own. Circularity Check: Calculate the average circularity error to test precision. Input Visualization: View real-time X/Y coordinates and button presses. Works with all major gamepads, including ALPS, Hall Effect, and TMR sensors.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
