> is to have a device that a kid can accidentally nuke To be honest the large majority of RPi users I have ever met are only adults. Are there a lot of kids who are using it out there?

Actually, yes. They're even good in a classroom because even if a kid screws one up, it's not hard to teach a public school teacher how to re-image an SD card. You dont hear about it as often because for reasons, the kids aren't exactly encouraged to reach out to adults on the internet. Dogs on the internet and all that.

You sir, must have never played the IT guy to this teacher you speak of in our public school system. I challenge the “easy” assertion with great confidence.

/meant humorously but also seriously serious.

Check this out, I hadn't heard about it either but am testing it on a ssd now. https://dfarq.homeip.net/fix-dead-ssd/

Great article, thanks!

I got a pi 400 to replace a 2009 mac mini that was serving as the kids' computer but was struggling to play the online games they wanted (including scratch) because of missing webgl support in recent chrome updates. Performance is roughly on par with the core 2 duo in the mini, but the graphics is more powerful and fully supported by webgl, so in practice it struggles less with the scratch environment and online game…

I did some quick testing of IO games on mine and was quite disappointed, when even Slither.io cannot be played smoothly in a browser (a relatively simple 2D game) then the experience is quite underwhelming for a machine that has had this many iterations.

Anything web browser based is a disappointment on the rpi, and that's just it I think. Native apps work fine, emulated old games work fine etc.

Can the 400 receive a bluetooth signal and act like a remote speaker? Specifically is the bluetooth hardware capable of that?

The ordinary raspberry pi can, so I would be very surprised if the 400 couldn't.

I understand why the Raspberry Pi uses SD cards (cost, simplicity, ease of use) but the entire line would be so much more useful with onboard eMMC storage. SD cards are great for keeping cost down and getting started quickly by flashing OS images from a PC. However, enthusiasts spend so much time fiddling with external storage options and cobbling together messes of powered USB hubs, cables, external enclosures, and…

> and fiddling with kernel issues (USB attached SCSI)

That's actually a good thing, the raspberry pi community uncovered a ton of issues over the years related to storage drives over USB, which has been or can now be patched in the kernel to make such things more reliable.

I think all I had to do to get it working, now that the USB boot feature is out of beta, was to boot Raspberry Pi OS from an SD card and do a normal "apt upgrade". This automatically downloads and updates the firmware[1]. After that (and possibly rebooting?) I could run raspi-config and enable USB boot[2] there. [1] https://www.raspberrypi.org/documentation/hardware/raspberry... [2] https://www.raspberrypi.org/docume…

But that still requires an SD card to bootstrap the process...

Yes, once, during setup. But you need to run raspi-config anyway to change the settings, so you need to boot into Raspberry Pi OS somehow even if you're going to be installing something else on the USB drive.

Personally I wish they'd add an m2 slot and scrap the SD card. It really is the bottleneck of the whole system. But they walk a fine balance with PCB space, backward compatibility, performance, cost and user-friendliness.

yes but an sd card can be bought for less than 10 $/€, whereas an nvme disk would cost about the same price of the whole rpi.

you have to keep in mind the original goal of the raspberry pi project.

if you want nice performance and low power consumption, you're better off considering a cheap intel nuc.

"Static electricity from the carpet discharging into the joystick port of a Commodore 64" Changing the CIA chip will fix the machine.

In my head at least, that’s a pretty good determinate of “Bricked” Does it require a soldering iron to fix it? No. Not “bricked” Yes. “bricked” (But I also totally accept that technical people are going to lose the language war here, same as when I used to rant about rc quadcopters not being “drones” since they’re not autonomous.)

To some people, soldering isn't a big deal.

To others, having to do a full drive reformat may be as intimidating as using a soldering iron.

Contrast to the second point, where non-autonomous quadrocopters are emphatically not "drones". Unless you consider the IMU and feedback loops that keep it level "autonomous", since it is technically some degree of autonomy...

Anyway, I'd be a little more specific and say something is "bricked" when it cannot be repaired with the speaker's skill level or equipment.

Ultimate bricking would be frying an IC with e.g. heat or ESD. Good luck removing those few hundred atoms shorting something inside.

It depends what you want to do with it. If you want to use it for a mobile robot, run the Raspberry Pi off a battery, then yes, power does matter.

I suspect the power draw of a mobile robot would be dominated by the motors, would it not?

The motors aren't necessarily constantly on, and you don't need very big motors for a small robot.
