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.

I went as far as designing new parts to repair this #Amiga 1000 keyboard... linuxjedi.co.uk/the-legend-c...

An #Amiga 500 RGBtoHDMI with audio test…

Testing the output of an #Amiga 1000 RGBtoHDMI with audio injection. I’ll be opening up orders soon 🙂 (A500 version also on the way)

I have a boxed #Amiga 1000 on loan, with an option to buy it later. Here is the blog post where I start restoring it. Great timing given that this year is the 40th birthday of the Amiga 1000! linuxjedi.co.uk/unboxing-a-l...

A friend gave me this boxed beauty last night. On loan but with the option to buy it from him.

Logged onto my old email account today. It appears 7 months on, I have been unbanned by WordPress. I hope the people that mattered got unblocked, and that they have been given an apology.

One of the magic things about being a human engineer is you can go to sleep with a problem and magically wake up in the morning with a solution in your head. One of the curses is you might wake up at 04:00 with the solution in your head. Good luck getting back to sleep. 😊

If you are a retro gamer who likes Beneath a Steel Sky or Cannon Fodder, you should check out a new game created by @stoocambridge.bsky.social and @tonywarriner.bsky.social from the studios behind those games Kickstarter launched <12 hours ago, nearly 200% funded! www.kickstarter.com/projects/ton...

A1200 is a lovely machine, and with a PiStorm32 absolutely amazing! Also really expandable with all modern toys. love my A1200. My A4000 was too expensive really, but I bought it "broken" so it was cheaper than most, and @linuxjedi.co.uk fixed for me - the star that he is. 😁

I saw this headline and thought it looked familiar. Completely forgot for a second that I wrote this feature and blog post 🤦‍♂️

Needed to do some TPM testing at work and the only Infineon TPM I had was on mikroBus 😂

I recently had a chat with @morefunmakingit.bsky.social about retro computer stuff for his new podcast. You can watch it below 🙂

Figured out why my Fluke 45 stopped working. It actually had the battery module in it (I didn't realise) and the battery module is dead.

I have been repairing an #Amiga 4000 motherboard with lots of little faults, none of them battery damage related. This post contains the details of what I found and how I fixed it. linuxjedi.co.uk/amiga-4000-w...

We have a number of community "creators" on the RHD discord server, along with a growing bunch of YouTube channels. Come say hi!

I was recently given my own channel on the Retro Hardware Discord by @morefunmakingit.bsky.social. It is here for anyone who wants to join in: discord.gg/ajCbRtJR9h

I might have found a board which is too much of a challenge…

This morning I repaired a faulty #Amiga A3640 CPU card, this is a short post on how I diagnosed and fixed it. linuxjedi.co.uk/amiga-a3640-...

I recently had a chat with @kateholterhoff.bsky.social about the #WordPress community. It is worth a list if you want to find out a little more about the battles going on.

I upgraded my @frame.work laptop recently, which in this case meant a motherboard swap and a new matte display. For a small fee you can buy this case. It turns my old motherboard into a desktop PC, which will be for @appleyardcandles.bsky.social to use in her new workshop.

It seems no matter where I work, I can't avoid terminology which is difficult to say in public in the UK around non-technical people. In databases it was "Mongo". In cryptography, it is the term "nonce".

For those who missed the @wolfssl.bsky.social / ST Micro webinar on STM32 MPUs I gave earlier this week, the recording is available here: www.youtube.com/watch?v=cRsO...

I chatted with @linuxjedi.co.uk about what he terms "a war going on within the @wordpress.org community." For this @redmonk.com conversation, we discuss the current litigation, it's broader implications for oss, and his WordPress Slack ban. redmonk.com/blog/2025/03... youtube.com/shorts/c-sWc...

It took me way too long to spot this blob of plastic. It was causing the 3D printer bed leveling to constantly fail.
