Citizen Water Signal - Public Launch
Making unsafe tap water visible before it becomes a crisis.
What it does
Recent reports of tap water contamination in cities like Indore and Delhi in India are alarming with hospitalisations and deaths reported. These problems are often hyper-local and remain invisible until they escalate into a crisis. I built Citizen Signal: a non-commerce citizen-led platform for residents of India to anonymously report how municipal tap water looks and smells, before treatment. Individual reports are subjective, but aggregated patterns create public visibility and accountability

A couple of months ago, I built this app to help identify people stuck under rubble. First responders have awesome tools. But in tough situations, even common folks need to help. After what happened in Myanmar, we need something like this that works properly. It has only been tested in controlled environments. It can also be improved; I know BLE is not _that_ effective under rubble. If you have any feedback or can contribute, don't hold back.

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
