Hosted dashboard for your personal weather station.

https://weatherstage.com/

I had some custom build scripts and sites for my dad and myself and was thinking I could make a simple SaaS out of it. Super early and didn’t advertise anywhere yet since the actual dashboard is very simple right now but it works and I keep adding the features I want to use myself.

Example dashboard: https://warnitz.weatherstage.com/

If you want to try it out, I suggest you write me at hello at domain and I will get you going. Let me know the type of weather station you have!

I'm experimenting to see if frontier LLMs can do practical CAD modeling. I'm starting with a single task: designing a wall mount for my bike pump in OpenSCAD or CadQuery (two code-based CAD systems).

None of the frontier LLMs (Gemini, ChatGPT, Claude) produce usable designs when just prompted with some photos of the pump and a written description of the mount. I'm now building a simulator in Mujoco that the LLMs can use to test and iterate on their designs to see if they can do better in this setting.

I'm hoping to make an interesting blog post of it and maybe end up with a usable wall mount design.

Building https://floxtop.com, a native Mac app that organizes your files.

It looks inside each file to see what it’s about, then moves it to the right folder for you.

Everything happens on your Mac, so nothing leaves your computer. No clouds, no servers.

It works in 50 languages (including English, German, French, Spanish, Swedish) and with images (OCR and object recognition), PDFs, Microsoft Office, ePubs, text, Markdown, and many other file types.

If you have messy folders anywhere on your Mac, Floxtop can help.

I shared this last month, but I’m still having a lot of fun working on it.

I made a daily word puzzle called Tiled Words.

https://tiledwords.com

Currently about 2,000 people play every day and I’ve released 59 puzzles!

One feature I’m excited about is crowdsourcing puzzles. Today’s puzzle is a “community puzzle” made entirely from clues that players submitted! I plan to do this every week or two.

I wrote about launching and the first month of puzzles if you want to learn more!

As we pile more and more abstractions on top with AI, I have been on a really fulfilling quest fueled by curiosity to go more low level.

I've been doing a lot of assembly, C, WASM and plan to top it off with a look at GPU instructions and PTX. I haven't learned as much as in the last two months in years, it's been great. And surprisingly everything has turned out to be much simpler and easier to implement than expected once demystified.

Now to be fair, AI has sometimes given me pointers when I didn't fully understand something. Using Gemini 3 for free has been nice in that regard. However I consciously try to only implement code myself and to actually make sure I learned something that sticks.
