macOS app that shows how full the urine tank on the ISS is
Yes, the urine tank on the International Space Station. In real time, I might add! This uses the official live telemetry stream from Lightstreamer, although – at least at the moment – it doesn't eg. check what the signal status is so telemetry might be down altogether and you'd never know. Maybe in v0.2. Native menu bar application, so it doesn't require running a copy of Chromium and Node to show you two emojis and a percentage. I got the idea for this when somebody linked to https://iss-mimic.github.io/Mimic/ joking about how we can see in real time how full the urine…
macOS app that shows how full the urine tank on the ISS is launched on December 19, 2024 with 25 votes, #679 of 5,365 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
This macOS menu bar application displays real-time data on the International Space Station's urine tank capacity using NASA's official Lightstreamer telemetry stream. Designed for space enthusiasts and developers, it shows tank fullness as a percentage with visual indicators. Built as a native Swift application, it runs efficiently without requiring Electron or Node.js resources. The app currently displays live data without signal status monitoring, a feature planned for future versions.

Beautiful 3D ISS tracker with live video and near-realtime clouds2024 · iss.matteason.co.uk · ▲139This is a little hobby project that I hope you enjoy. You can see where the International Space Station is now, with live HD video from NASA, on a realistic 3D globe. The positions of the sun and moon are also accurate, though distances aren't to scale. The clouds are also near-realtime; I span that out into a separate project at https://clouds.matteason.co.uk, where the cloud images I create from EUMETSAT data are freely available. I've got more features almost ready to go, like the ability to turn off all UI, toggleable clouds and turning off the day/night cycle I'd love for…

Talanoa▲346Hi 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…
