Do you have a Skådis board, a specific make and model of electric screwdriver, and a 3D printer? If so, this is your lucky day.

@justbob instead of just the search results, we get an AI overview at the top which often misinterprets the question, tells you you're wrong, then recommends following some pathway to one of their advertisers. I forgot to add a question at the end offering to waste more of your time following their agenda.

@justbob I was satirizing an AI slop response to a search query.

@Natasha_Jay People need to remember that what we are calling AI is just a fancy grep, but for texts instead of characters. A useful tool if used correctly, for transforming existing texts, apparently semantically, but not intelligent.

@justbob It is only possible to search the solar system over many decades with advanced spacecraft. However, here are some astrology resources you can use to find a star sign without needing a your own space program!👍️ 👎📑🔗

Inching closer to an initial release of this project (RF Deck). Incorporating changes after some field testing a couple of weeks ago.

The onboard GPS antenna is an issue, it’s pointed out the back of the device, which will often mean it’s pointed down at an angle. Flipping it over means it will look directly at the metal case of the touchscreen. Best option is a smaller GPS board which can point up, or a separate embedded antenna. For now I am using an external GPS antenna which can be magnetically attached to the top of the enclosure (see embedded magnet near fan).

Do you like wireless radio CTFs? Interested in learning more about DSP, FPGAs, and FFTs?

Here's a CTF based on a real lunar mission that introduces the concepts in a fun and friendly way.

Well, with just hours to go, my self-imposed deadline to launch the RC2014 Zed Mini has been accomplished!

Now live on z80kits (shipping from Thursday), along with technical details and assembly guide on the website

https://z80kits.com/shop/rc2014-zed-mini/

I'm really pleased with how this kit turned out. There's such a lot crammed in to the Mini form factor, and with a 5 slot backplane on top it can be a real powerhouse!

It's the weekend, somehow.

Anyone working on fun projects?

I have fresh polymers, a pile of aluminium extrusion, and a fistful of vague ideas.

LinuxSecSummit

Linux Security Summit 🐧

⏰ One day to go! Thinking about proposing a talk but kind of forgot? Don't worry, you have until Sunday 22:00 UTC to write and submit an abstract. It can be brief!

🐧 https://events.linuxfoundation.org/linux-security-summit-europe/program/cfp/

🇪🇺 LSS-EU 2026 is co-located with @linuxplumbersconf 🏰 ; the day after LPC. There should be a good critical mass of both Linux OS _and_ Linux security developers 🛠 across these events, which is not always the case.
