SaaS: Sunshine as a Service. ☀️

What it does

Living in Denmark means constant gray skies. Bestil Solskin is a "Sunshine as a Service" experiment that replaces weather-app anxiety with a simple SMS. How it works: Pick your city and pay 20 DKK. Every day at 18:00, our system scans the APIs. If the clouds part, you get a "delivery" text with your sunshine’s arrival time. It’s the ultimate low-cost dopamine hit for anyone tired of the rain. Order some sun for yourself or a friend.

  We built CircadianLab, a free in-browser tool for lighting design. It uses webGPU shaders to calculate melanopic equivalent daylight illuminance (mel-EDI, formerly EML, relevant for circadian rhythm and WELL v2 compliance), photopic illuminance, UGR glare per CIE 117, and actual daylight through windows and skylights. It has a database of 400,000+ IES files from 81 lighting manufacturers and supports easy sharing of scenes/configs with other people. Daylight uses the NREL Solar Position Algorithm and a Perez clear / intermediate / overcast sky model, mixed into the same…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  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
