Training AI models on videos of drones scrapped from public sources. Everyone in Europe is building ani drone systems and nobody has real data. Lots of companies operating on synthetics only. Lots of work to automatically filter and process scraped footage into something that will train well.
Mentally that sounds like a grim project

#622It takes in your calendars and gives you time slots where you can put your head down and work! It built it for myself, but a few people found it interesting, so I thought of publishing it.
If you are someone who manages multiple calendars and multiple calls per day, then you will find this useful!

#623It's already working, but it requires so many tweaks and adjustments that make the project hard to finish-finish.
It's controllable by an ESP32, can run automated cooling benchmarks (to find the power vs temp sweet spot) and is pretty much all made out of metal, not 3D-printed – I've learned a ton about working with metal, especially around drilling, cutting, and tapping/threading. Who knew precise drilling a solid copper block could be so tricky at times (saying this as a person who has never drilled anything except wood/concrete before)!

#625I've been on-and-off working on a portable, sturdy electrical cloud chamber for a couple of months now. It's a device that lets you see ionising radiation with a naked eye, right on your desk. It's already working, but it requires so many tweaks and adjustments that make the project hard to finish-finish.

#626Currently just the cloud hosted version (https://gitncoffee.com), but plan to open-source most of it when it's more complete.

#628The next step is to improve the landing site. I like the current no-frills design, but unfortunately I think I'm in the minority.
Feature-wise I'm planning to add support for getting alerts via Slack. I'd also like to make use of certificate transparency logs, alerts to start with but maybe for other stuff as well.
The stack is C#, .NET 10 and PostgreSQL 18 running on Hetzner VMs. I also self-host Forgejo and OpenSearch on Hetzner VMs. I recently switched from VS Code to JetBrains Rider and I think the latter is much better for C#. (I'm using Linux so Visual Studio is not an option for me.)

#630I recently inherited my grandfather's typewriter that he inherited from his father (circa 1940). And Id like to put it to good use. My wife challenged me to make a project. Now Im getting my wheels turning with a new project to type and ship letters custom made with 280 chars and some other personal touches.
