I created a custom hardware solution to prevent my parents from walking in on my meetings. Because a locked door is just a suggestion. I live with my parents and work from home. I have a nice (makeshift) office room but a lot of times my mother asks me if she can come in the room for reasons I won't get into. This is a story of how I made a custom device to let anyone know if I'm busy with a meeting or not, when it ends and a lot more. This ends with me designing a custom binary protocol that has only one user in the world. I had an ESP32 lying around from a previous project which I didn't complete (I call it "iterative abandonment," others call it "laziness"). I was also incredibly bored.…from apoorv.page

    Hi HN, I’ve tried dozens of reminder and habit apps over the years. They’re all polite. Gentle. Easy to ignore. So I built something intentionally different.

    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
