For Black Magic Probe v3 development, I designed a little breakout carrier. We will likely spend some quality time with a debugger hooked up to it so I think it will be a worthwhile. The SMT threaded inserts are really nice. I also 3D printed a base to keep the TH pins from scratching the table. ;)

This is a grassroots campaign:
“Abughazaleh reports over $1.1 million in individual contributions under $200, making up around 74% of her contribution totals.
In contrast, over 90% of Biss’ campaign contributions come from big-money donations of over $200.”

Hey everyone! Tune in to @katmabu.bsky.social stream either on YT or Twitch. They are trying to prove that streams are better way to spend time of candidates than calling rich people for donations. Let's show their theory is correct! :) Consider donating at secure.actblue.com/donate/katst...

I might be using codeberg (aka. forgejo) more in the future. I am unreasonably excited to see how many merge options it offers, but mainly "fast-forward only" is in there! ❤️ Why can't I have it on GitHub 💔

I am bit shocked that there were only 2 other people in 7 years that also thought that having resizable objects (logos, graphics) for PCBs would be a useful addition. :/ Running campaigns around useful KiCad feature requests is something we should be doing? #kicad #pcb #electronics #opensource

For some time @securelyfitz.bsky.social and I have been working on a new hardware security tool. A tiny m.2 WiFi module sized FPGA board allowing the access to the PCIe interface. You can sign up for updates for when the campaign launches, some time next year. #EpicErebus #fpga

Nah man, the AI knows nothing. It has no understanding. No critical thinking skills. It's just giving you a reasonably likely response to the garbage you yell at it. It's a Ouija board with terminal access.
