Posted mostly because @kari.bsky.social said it would be cool to see it, my current soldering setup. JBC T210, T245, PA120 tweezers, DR560 desoldering gun, JT 6040 hot air / tripod vacuum system.
Also, watch Kari's videos if you are into retro stuff and on a soldering journey.

It seems JBC used my nickname on a package. I can't see it on my account anywhere, but it put a smile on my face 🙂

17 years ago I was at MySQL and hacking in useful small UX features in my spare time. Today I’m still doing it for projects I work on.
It is now much easier to see how much of an impact different compiler options have on memory usage as well as performance.

“Recap it!” isn’t always the cure.
A badly recapped Amiga 1200 came across my bench, and what I found might surprise you.

Why Recapping Isn’t Always the Cure: And Amiga 1200 Repair Story
I often see on places such as Facebook that an Amiga owner will show a fault they have with their machine, and the immediate response you’ll see is “recap it”. Now, I’m not saying that recapping isn’t...

I travel with my laptop a lot, and one KDE Plasma feature I’ve always missed is auto-changing time zones.

KDE Plasma Automatic Time Zone
I have been a full time KDE Plasma user for quite a while now. Whilst I do not miss much from GNOME, and love the way I can make Plasma my own, there is one niggle that has been missing for a while.

The wolfDemo Board Story: From Idea to Reality
I work building open-source cybersecurity solutions for wolfSSL. These solutions often involve embedded environments, which is why we attended Embedded World in Nuremberg this March.

An #Amiga 1200 landed on my repair bench that was stuck in a boot loop. DiagROM showed Paula behaving weird. Found the Paula capacitor loose. Can you then see what I spotted was wrong with it afterwards?
So obvious that I wasn’t even looking for it 🤦

DoohicKEY v2 prototype. Might not look like it, but it has about a dozen new features. It will require a second revision before it is released and there is more firmware still to write for it. But the basics are working.

Yesterday I was at an event hosted by Retro32. I brought some of my soldering gear, some testing gear and “Jops” (an Amiga 4000 which used to be owned by @stoocambridge.bsky.social). I talk about it all near the beginning of this video:

Just had a “dude, where’s my car?!” moment.
Took the bin out, panicked my car was gone… then remembered I’d picked Natalie up from work and we walked home. Car’s still in the town car park 😂

I find it fascinating that there is a famous UK tech company whose job application process is so bad, that it has been a running joke in the industry for years. From what people said today, that company still hasn’t changed it.

For any of my US customers here, I will be suspending US shipping in the next couple of weeks. Tariffs will have to be paid at point of shipping and due a small print thing it is looking like it will be a minimum of $80 per package.
