Yes, I think Gordon Hollingsworth from Raspberry Pi has posted somewhere specifically how to do it (maybe in the comments on the post on the Pi website?).

Found it! Merci :) >It would be possible to do this, but you’d have to run a simple buildroot SD card which runs a suitable dwc2 OTG HID driver to pretend it is a keyboard… Otherwise, you can use the Pi 400 as a Barrier server to the other computer… See my other blog post for details! Gordon

Nice, it's probably using the USB gadget functionality. That probably means you could modify the image to access a bunch of the ports. Having the ability to turn my Pi Debugging Keyboard into a USB Ethernet adapter would have some advantages.

Does anyone have any good recommendations for resources / projects for a computer-interested 12 year old? I was thinking of buying a Pi4 for my niece who is “getting into computers” but I fear my tastes in what constitutes interesting or age-relevant content might be out of touch. I also, look at the various books that they sell on the Raspberry Pi site, and worry that they’ll be out of date pretty quickly. If anyone…

The raspberry pi foundation put out an excellent magazine https://magpi.raspberrypi.org/

I hadn’t seen the magazine, but this looks like a great idea to keep abreast of current and curated activities. Thank you for that pointer.

That would probably quadruple the price. Look at PiTop. They used to include batteries and a display, but have moved away from that, as these are the most expensive peripherals. You can by a cheap display, or use your existing TV. A USB power supply isn't too expensive either.

Why quadruple, anyway? I've seen quite a number of ~$200 laptops and found their screens and batteries tolerable (although, obviously, not really good).

It's a matter of scale. $200 laptops are great if you can produce thousands of them and have a market willing to buy them. That's why Chromebooks sell so well. Let's also not forget that Chromebook/Android devices enjoy the subsidy provided by Google's advertising division.

I doubt the Pi 400 with a screen, battery, touchpad and integrated webcam would be able to sell in numbers that would justify the manufacturing and distribution costs.

> The district couldn't secure all of the necessary Chrome Books, and some students have been left attempting remote learning via their parent's phone, or simply left behind. A cheap mass market device has some truly amazing potential to fill in these gaps at the same time that it enables more advanced S(T)EM learning than you could get with a typical cheap Chrome Book. How many households in this situation have an e…

The pi lets you work without google spying on you. That’s why I want this as an alternative to a Chromebook. My kids can learn computing without feeding data to google.

"Does the sub-licensed Intel Management Engine on the Broadcom CPU in the Raspberry Pi 400 call home to Intel servers?"

Tomorrow's headline?

> This RP400 is small, can be taken everywhere by kids Not usefully it can't. There's no display, so that "everywhere" is restricted to places that have an HDMI display just hanging out. Which is then a vanishingly small number of places. And since we're talking about kids - places with a front panel HDMI port, which is even rarer. Or you have to pair it with a portable monitor, in which case you spent as much as an…

> "everywhere" is restricted to places that have an HDMI display just hanging out. Which is then a vanishingly small number of places. Wait what? Doesn't virtually every TV sold in the last 10 years have an HDMI port?

there's less and less accessible ports. tvs are large, mounted high up and the cables aren't long enough to be comfortable.

Apple made the chiclet keyboard cool again. It might be OK. Gen-x who remember the TRS80 MC10 and its keyboard remember chiclet keyboards as not much better than membrane keyboards (Consider the ZX81 Spectrum) But decades later Apple started shipping chiclet-appearing keyboards that actually worked, so the style has been somewhat revitalized. That said, yeah they could be shipping a 1980s quality chiclet keyboard or…

I have a hard time believing there is a chiclet keyboard worse than the Atari 400 membrane. "Gen-x first computers" sounds like an interesting site

Actually there were differing qualities of these manufactured. I had one of the early ones and it was fantastic, I could run my fingers touching over the surface and lightly depress while dragging and the audible feedback had such low latency: joy. Sort-of regretted replacing it with mechanical keys. Later Atari 400s had barely registering keypresses that was a workout for your fingers.

With USB sticks it's a different story. There are some manufacturers like Sandisk who claim they use wear leveling in all of their current USB sticks. microSD is a mess in this regard. Wear leveling is less common there and only present in very specific and expensive niche models.

[citation needed]. I can’t believe any but the cheapest no-name SD cards would have absolutely no form of wear leveling.

It does look like there are many of cards that don't claim any sort of wear leveling (doesn't mean they don't do it at all but they don't call it out). This is surprising to me, but if you want to make sure you get a card with wear leveling, look for it in the specs. These SanDisk industrial cards[1] are ones I've used in the past that specifically claim they do wear leveling in the spec sheet: Advanced memory management FW features power immunity, auto/manual read refresh, ECC, wear leveling. They're also only a few bucks more than a "normal" microSD card.
