Hello everybody, I am new to HN but I must say I really enjoy the vibe. I have been coding for almost 15 years now and after having fired myself 2 times in a year (both from corporate and startup worlds), I decided to dedicate full time to what I love: building cool stuff for my own, with the dream of becoming a solopreneur. Among my many passions (some dangerous), I love scuba diving. All the logbook apps I tried had these problems: - Distant from the user experience and needs. - Complicated yet useless features that no one uses. Literally no one, not even those who created them. - Ugly. -…

Hey HN, I built depthviz, an open-source CLI tool that generates depth & time overlay videos from dive logs. It supports dive computers (Garmin, Suunto, Shearwater, Apnealizer) and manual input for freedivers who want to enhance their footage with real-time dive data. Why I Built It: Adding dive data to videos manually is tedious. depthviz automates this by reading dive logs (.fit, .csv, .xml) from various sources, generating an overlay video with real-time depth, allowing full customization (fonts, colors, depth smoothing, stroke width), and running on Windows, macOS, and Linux.

Submarius started as just a dashboard for diving conditions, but I quickly realized that there is simply no API for water clarity, nor even a simple way to calculate it. Divers call it viz, and it is one of the most consequential factors for a diving experience. So I dove the viz rabbit-hole. I landed on a state-augmented ensemble kalman filter. More details on the /clarity page. My question for the HN audience is if anyone knows of a better way of doing this? There is a ton of satellite data to train on, but a lot of it is messy (clouds read as turbid water, shallow reefs reflect…

Free online timer with stopwatch, Pomodoro & productivity

Minimal online date calculators and timers: pomodoro, countdown, stopwatch, alarm clock. Pomodoro is easily configurable with the ability to add additional timers and to set predefined break activities. I like to add a few leg and core exercises (variations of squat and plank) and some stretching. Helps me to remember to move away from the monitor and relax the brain.
