Bingo! That sounds just perfect. All I need.

Many thanks.
Barrier is also in the repository. Evaluate both and then choose the best one for your needs.

Code: Select all

These are amazing. I have 2 usb kvm’s but the software doesn’t take up USB ports and can attach more than 2 machines

It still looks like a good starter machine for your kid or someone who wants to get more into Linux OS.
If the kid does not want it, dad will use it, it is even good enough for mum's computing needs.
One for everyone? Cheaper than any replacement PC.

Going to be interesting when more wake up that they can reduce their carbon footprint with Pi's.
Low power and more room on desk etc.
What are the gaming industry going to do, only sell to hard core, water cooled gamers?
Have they forgotten how the gaming industry started?

Looking forwards to seeing custom keyboard Pi's popping up all over now.
The CM4 might have a role to play in that.
Going to need Pi network servers.
Imagine netbooting to your pick of OS.
Great for schools too.

Will the CM4 I/O with PCIe drive make a better server?
More learning.
Get one. It’s an extremely handy utility computer, like having a Swiss Army knife.

I am planning to power my Pi from an external screen, zip tying the power lead to the monitor lead; only one 12v lead required to power both.

I think you might have missed the new Xbox and PS5. That is where the money is in gaming.
You are right, don't have any of those things, so I totally missed the latest opiate of the masses.
Wonder what has been distracting me from these wonderful raytracing boxes that are better than reality?
Yikes, the price of a good second hand car? $4,500 AUD, that is a rip off eBay price.
Put's the price of the Pi400 in the bargain box.

Too many dystopian games out there anyway.
Good zombie killing and rebuilding programming going on as well
Already signs of "Go Woke, Go Broke" are appearing in the gaming industry.
I wonder what numbers these boxes are/will be selling in?

On my Pi's I can hack the AI's and compile Warzone2100 , so I can practice making better killer AI's ;)
Or learn how they work so I can practice tricking n destroying the killer AI's :lol:

With these new boxes n games so realist, what is next for them?
Have we reached peak gamer experience yet?
I'm not saying I agree with modern gaming, indeed whilst I was around at the start running my own educational games company and then worked on a few larger '90s games as things evolved from one-man shows to larger projects, I don't understand how gaming has evolved either. But we now have hundreds of million dollar budgets for games, and sales volumes of PS5 and Xbox will far exceed anything coming out of Sony Pencoed.

But they are different horses for different courses so as long as the Pi400 does make it into schools to show kids there is life beyond killing zombies, or at least they learn the basics to be able to go on and work on programming those games as they are a major contribution to the UK economy, then it will have achieved its purpose in life.

And your AI hacks will need more than a Pi to cheat the big games. Current ones use arrays of GPUs similar to bitcoin mining and still get detected by the servers using even larger arrays of GPUs :-)

As for the Raspberry Pi 400 itself, would it be possible to get on a wait list for one of the yet-to-be-shipped kits with localized keyboards? Even better, is there a reseller that allows pre-orders of out of stock items?
Don't know, check the product pages for your local reseller and ask them.
I checked four of the localized sites, but based on the existing older stock, the prices, and the stated delivery times it remains much faster and cheaper to order from the UK -- at least until [deleted]. As far as I know only the shops in the UK have a large selection of add-ons and accessories, anyway. I'll try asking them.

How did the Raspberry Pi engineers compute how thick the cooling plate should be? Would the cooling be improved if the plate was thicker or thinner than now? The keyboard would weigh less if it the plate was thinner, which would be an advantage for e.g. shipping costs.

The plate performs 3 "official" functions, cooling, shielding and structural reinforcement, Unofficially, the extra weight means the Pi 400 tends to stay where you put it and the cables you plug into it don't drag it all over your desk!

Exactly:

"cooling, shielding", that the Stenson part.

"reinforcement", that is the Harrison part.

I'm dubious that cutting the weight of the Pi400 would have any effect on shipping costs. I keep worrying that a strong breeze would blow it away as it is. (It's *significantly* lighter than my main keyboard, which has a shipping weight of 5 pounds.) It was noted in one post that, if you get the kit, the *book* weighs more than the Pi400.

If you do a cover, please be sure to do it in both red and black, and make sure it gets publicized enough that people notice it. Thanks in advance...

I've got some of several sets of these and use the GPIO cover on my Pi 400, it works a treat but it's a bit awkward to remove as it sits flush with the back of case.

Maybe a cover could be designed that stuck out a bit, or maybe had a ridge down the centre to make it easier to remove?

Not to throw down on this idea but wouldn't that be hard to remove and redundant? Just tape over the back of the case.

Tape won't stop an object piercing the tape and shorting the pins if you drop it, and if it's not powered, it may still physically damage the device by bending the pins.

A 2x20 male to female adaptor should work and allow hats to still be used by removing the adaptor.
Just have to get used to using a different kind of cable (male Dupont instead of female)

Taping over back of Pi400 case would not allow to use the GPIOs easily.

I thought on the "hard to remove" part and found a solution.
I had no 2x20 header, but I had two 1x20 headers I superglued together to get my 2x20 header.

Next, a 1x8 Lego piece would have fit perfectly over the headers and could be superglued.
I only found 1x4 and 1x3 Lego pieces.
For making the 1x3 fit next to the 1x4 I had to dremel away the inner border as well as two sticks inside 1x3 Lego piece.
After that I superglued 1x4 and 1x3 together and added superglue to now 1x7 Lego piece bottom.
Then I pressed it over 2x20 header and waited until all was stuck.

Now putting header over Pi400 GPIO pins is easy, as well as removing -- just pull the Lego piece in middle:

It is funny that people think we are a "Broadcom outfit".

We use their chips and have a decent supplier/manufacturer relationship, they help us, we help them. And that's pretty much it. They probably still think Eben works for Broadcom.

I think a female socket would have been more appropriate on the Pi side in the first place. As this is a consumer device, things should be plugged into it rather than the other way around. This is because you don't want live pins sticking out when not in use. Imagine what it would be like if the mains sockets and plugs were designed the other way around.

To emphasize this point, the male header on the Pi 4B is fine because that circuit board is a component that will be internal to the case. On the other hand, the Pi 400 is a finished consumer product.
