Police at my door this morning made me late for a meeting. Long story, I'll let you caption the CCTV grab of my back garden at the time. For the record, those aren't my sheep 😂

It seems that some people paid an average of over £80 for the ebook version of my 15 year old book this quarter 😂

The ChatGPT year in review is kinda cute.

Hackaday covered one of my blog posts! 🙂

Sometimes I'm proud of the small things I've done in the past. This is a glowing lightsaber for my LinuxJedi logo I designed into a PCB 4 years ago. It is brighter at the bottom than top (intentionally) and it worked first time. My theory worked perfectly.

I bought it a few years ago, in a broken state - and it was still stupidly expensive, but not obscenely stupidly expensive! 😂 @linuxjedi.co.uk then fixed it for me, and it's now an amazing machine, complete with ZZ9000, which also allows proper HDMI output - which is so cool.

Picked up a faulty #Amiga 600 motherboard for £41 and turned it into a fully working board. Reset issues, bad caps, dead composite output, all fixed. linuxjedi.co.uk/reviving-an-...

I recently repaired an A1200 with a tricky hidden fault, only for it to return with even stranger ones. Broken HSYNC trace, collapsing ceramics, PS/2 mouse weirdness, audio clipping… this board had everything. linuxjedi.co.uk/the-amiga-12...

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. www.wolfssl.com/benchmarking...

Medical Professional: "We usually only see this condition once or twice a year. Typically caused by stress. Are you going through some stress now?" Me: "Only all the time" MP: "Yea, you look tired" Erm... Thanks? 🙂

“Recap it!” isn’t always the cure. A badly recapped Amiga 1200 came across my bench, and what I found might surprise you. Full story: linuxjedi.co.uk/why-recappin... #Amiga1200 #RetroRepair #Commodore #RetroComputing

I’ve wanted an original copy of the CDTV version of Xenon II since I got my CDTV. It is extremely rare. I now finally have it!

Something I've been working on in the background this year 🙂

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 🤦

Over a decade ago, a bunch of us inside OpenStack were teaching people about cloud resilience engineering. Glad to see that today's outages show many didn't listen...

I guess my bag was ejected 😂

I have been working on the new version of DoohicKEY for #Amiga 500 computers. Here is a quick (low quality) video demonstrating some of the new features: www.youtube.com/watch?v=iIqO...

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.

I built the prototypes for DinKEY 600 and DinKEY 1200 yesterday. Cotton bud for scale.

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: youtu.be/Nh3McmZM5y0

Two boards codenamed “DinKEY” are amongst the four PCB prototypes I sent off to get made today. Firmware written for two of those boards too.

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.

Hotel trick I learnt this weekend: if you don’t have a bottle opener with you, the arm of the spring loaded mechanism for the door works great.

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.

I decided to move my main soldering bench to a lower desk. I was regretting starting half an hour in, but now I think I like it.

I was asked about the vacuum system on my JBC 6040 hot air station, so I spent a short bit of time making a low production value video demonstrating it: www.youtube.com/watch?v=Wbu0...

Update after my RAMCHECK blog post, the @adriansdigitalbasement.com video is available here: youtu.be/mRqsGytvSP8

It took me 6 attempts to pass Microsoft's Captcha on the Office 365 admin site today. Including failing the audio version. I think this proves I'm not human.

Over the years, people have asked me why the RGBtoHDMI can't do audio. Well, now it can. I have RGBtoHDMIs for #Amiga 500 with audio injection on pre-order available here: www.retrosupplies.co.uk/amiga-rgbtoh...

With help from @adriansdigitalbasement.com I was able to upgrade the firmware for my RAMCHECK memory tester. Here is the adventure I had: linuxjedi.co.uk/upgrading-th...

That’s new… box didn’t fit in the postal bag, so the stuck the sticky closing strip to the box.

I'm holding onto all my bad memories. Good thing they're easy to bag up.

I give you the @github.com 26 day month 🙂

It turns out a very reliable RAM testing device exists. I now finally own one! linuxjedi.co.uk/the-ultimate...

Interesting repair today. #Amiga 1200 Infinitiv Tower the owner imported from Poland. UK border force stuck their hand in it and managed to rip the reset wire connector from the motherboard. Breaking a trace & pad and snapping an SMD resistor. All repaired. bigbookofamigahardware.com/bboah/produc...

I managed to get my hands on a faulty graphics card that probably has the fastest VLB graphics chip that existed. This is how I repaired it (with benchmarks at the end). linuxjedi.co.uk/vintage-spee...

My #Amiga 1000 at @norwichamigagroup.bsky.social earlier this evening 🙂

A quick 3D print later and this #Amiga 1000 now has a side HDMI port for the RGBtoHDMI with audio capture. Ready for the @norwichamigagroup.bsky.social meetup tomorrow.
