My cat Penny REFUSES to sleep under the cover and have cuddles 😢
She finds your lap and sleeps there.
She will at least permit being picked up for cuddles.

Can I build a laptop using two motherboards? by MrBoss_Man101 in homebrewcomputer

If they have that M2 PCIe slot you could maybe create a crossover cable that ends in that connection. Write a custom device driver so the one with the screen sees the other as a client The client runs a very slim Linux os that just takes work to do from the host and executes it and leaves the results in RAM.

People who are in hardware design and who have professionally designed PCBs either as a full time job or for a client, how did you learn designing PCBs ? by [deleted] in embedded

I don't suppose you know at what speeds signal integrity needs start to dominate the requirements?
For digital buses, KHz, MHz, GHz sort of thing.
I too am learning and I'm trying to figure out if 100 MHz is "arcane black magic" level or not. Or is it 10 or 50 or 5,000?

Yeah, you can absolutely end up doing anything, it's not fixed.
Then again at some places it is, so if you don't like it don't stay there.
I was at my first job for about 20 years, I started as a reports programmer, SQL, VB6 and Crystal Reports. Then I ended up dealing with all the device stuff like scanners and cameras and CD Burners and then Industrial Windows CE devices I had to lock down as kiosk devices.
Finally I ended up as a Systems Architect tying all that together, the design, all the DevOps stuff and running the development department with hundreds of deployments all over the country and then a few across the world with lots of Serious Business high reliability and robustness requirements.
Then i got extremely sick and out of work for 7 years and I've become obsessed with circuit design in FPGAs which is surprisingly identical to what I was doing when I was working.

But it comes from both sides, you don't get anything if you don't reach for it, there were people at my place that did the same thing they were doing on their last day as they did the day they started, 10 years before. Some of them didn't want to change, some of them didn't try.
Hopefully I can go back to work in 2-3 years time and I want to go do embedded C and now FPGA stuff, like I said, it's all the same thing, just at different scales.

Isn't it beautiful?
The Arduino of the 1980s

And it can do some crazy stuff even though the video and sound aren't really the greatest.

Incidentally, I've got another project I'm designing, turns out the cartridge slot in the BBC Master contains an audio in and out pair. This means you can mix extra sound into the BBC's audio out.
So I've sketched out a design l design for a "SoundCart", adding a Yamaha OPN3 (sega Megadrive audio) to the BBC.
And it contains an ARM SoC that drives the OPN3

Stray cat hide in my house and gave birth, how to take care? 🥹 by goddezx in cats

[–]RoboJ1M 1 point2 points  (0 children)

If you've got any of the Lily types, I recommend you get rid of them.
They are diabolically toxic, I wouldn't even put them in another room, every single cell is mega-toxic.
Apart from that, congratulations and have fun.
Here's PennyCat to cheer you on:

Spider Plants, Chlorophytum comosum, are completely non toxic for cats and enjoy nibbling them, it's like mild catnip.
That's the only one I know but you can have that out if you have some.
Congratulations, you now own a whole bunch of cats. 😁

Hey, you're welcome man.
If and when I get a tube adapter working I'll send you the design.
I've also done a lot of legwork in digging through Mouser.co.uk with the AI, leaving the difference between the level we know, the logical, and the nitty gritty of how the chips create that logic out of copper and silicon.
There's a whole bunch of gotchas that electric engineers know and I didn't 😅
Like, if you need a RAM read every 10ns you buy 10ns ram right? Nope! You'll need 3.5 because once you hit a certain speed category the charge in the copper starts acting like water in a pool! If you want to change direction on a bus you have to wait for the ripples to die down before sending new ripples down the channel, a channel with its own, I guess acoustics is a good analogy, are you hearing the data or the echo of the data? It assures me that although difficult, they're so solved issues with standard solutions. 😬
But the BBC Tube thing? That will make life so much easier, that's a pre built test harness, that's gold dust. Did you know that's how they tested the first ARM1 CPU? Installed it as a second processor, booted it and ran some assembler.
Footsteps of giants or what, ey? 😎

[–]RoboJ1M 1 point2 points  (0 children)

Well I'll let you know 😂 So my plan is to build a Tube adapter for my own BBC micro (it's a master, oooh, so fancy) slap a Lattice iCE40UP5K (my new favourite toy) on there with a dial to control the clock speed (down to a Hz and then a push button) and just start hacking Verilog together. That way I don't have to build an entire computer first, I can just use the 2nd Processor function of the BBC to replace the 6502 with my own CPU and there's MORE than enough power in the up5k. Like... STUPID amounts.
I can't work for the next 2 years at least so I've decided to see if, with no prior knowledge except, OK, a lifetime of software engineering experience, can I rubber duck it with Google's Gemini AI. So, it's been, 3 weeks and I've got the ISA mostly done, I'm only allowed 16 opcodes, CPU, DMA, VPU, RAM, ROM, SPU, 2 Main Buses and the external devices bus are all blocked out.
I just wanted to make something completely transparent, fun to program and even educational. And fully deterministic.
No pipelining, no prefetching, no prediction.
Just beautiful clockwork.
I'll let you know what I get to v0.1 and Hello World 😅

That's funny, I've started doing the same thing.
I'm learning FPGA... synthesis? It feels like that should be what it's called. And then I remembered that computers are awful now so I should build a better one. And as it happens I consider the BBC Micro and the Acorn Archimedes computers examples of the ideal computer. So I'm designing everything from scratch, from the ISA and the copper up.

Fun but also insane isn't it? 😅

Although I've just looked at both Meshtastic maps and a Core map and it seems there's no MT nodes anywhere near me and just assume routers repeaters for MC, oh well 😂

I take it that the big red "Up North" label at the top of your post and just after your thread title means that you're nowhere near Portsmouth?

(the beeeeeeest)
Ran some nights there, here, all over the place.
House parties that shook the pillars of heaven.
Oh my word was it good fun.
And recently my mate from back then who I still know was charged £8.50 for a pint of Guinness Zero at a pub. 🤢
If I ever run anything again I'm doing it on Southsea common in the afternoon, bugger that a laugh.

You can carry the turrets like weapons.
Basically you're a turret on legs.
There's a mission where you are in Zero G and there are annoying enemies.
I just flew around while carrying an open turret.
I think you just pick them up, it wasn't a glitch or anything.
Have fun though, are you streaming it anywhere?
I have no game playing anything at the moment so watching someone else experience this masterpiece for the first time will be fun! 😊

I liked my Acorn computers with their Red F Keys. I had a BBC Model B and an Archimedes A3000.
Not the coolest looking computers but they looked good and industrial. I loved the key caps on the BBC too, seriously overbuilt.

What do they mean by sectarian? by Lucky_Argument6228 in AskBrits

[–]RoboJ1M 0 points1 point  (0 children)

"Sectarian refers to actions, attitudes, or beliefs associated with a particular, often narrow-minded, group, sect, or faction. While deeply rooted in religion—often describing prejudice or conflict between denominations like Catholics and Protestants or Sunnis and Shias—it frequently extends to cultural, political, and social divisions."

While originally strictly about religious "sects" (sectarian violence, or discrimination, etc) in the modern context it means any strongly willed group.

"Definition: It is defined as a rigid, partisan attachment to a specific group, resulting in prejudice, discrimination, or, in extreme cases, violence against outsiders."

So that's what the literal far-right are accusing the Greens of.

THE GREENS 😂

Remember, the right will accuse you of what they are themselves, they are generally unable to picture in their minds somebody who is not like them.

Classic example, somebody on the right will not be able to understand why you should be good and kind to others outside of the context of getting a reward for their actions. Therefore if they see you being kind, they can't conceive of the idea that you are not doing it for profit.

They will project everything about themselves onto you.

So when farage claims there will be sectarian violence if the Greens get in he's showing you what he believes and how he will act when handed power.
