1) You can hook this up to a TV. 2) Webcam isn't strictly necessary: You'll be able to "see" your teacher, type in chat, virtually raise your hand, etc. 3) This enables more advanced STEM (The "T" portion, really) not because it's a desktop but because of the built-in 40-pin connector opening it up to the massive catalog of projects that exist for the Pi platform already. 4) Perfect is the enemy of the good: You're c…

That 40 pin connector is a big STEM deal. First peripheral I would sell is an add on breadboard station with lots of good sensors, lights, input controls, motor drivers and such that is buffered to prevent damage and start producing education kits.

Here you go https://shop.pimoroni.com/collections/breakout-garden the easy way to add devices to the Pi. You add SPI and I2C devices and the sell a ton of different sensors, motor and servo units, etc

As an engineer/founder from India who dreams of access to the Internet for everyone on this planet, these are the efforts that make me smile. I am in the process of sorting out my financial situation - tough founder luck. But I am happy to order a few of these (and monitors) and rent a small garage to give local kids a free computer lab to learn. (Kolkata, India)

My mother runs (from germany) a local shelter for street kids in Kolkata. Let me know if you want to share some of your knowledge with these kids :)

Does she accept donations?

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.

if anyone needs a free monitor let me know, I got some spares.

seriously, I see people tossing LCD monitors and TV left and right

How many households in this situation have an extra monitor lying around to plug this into You just need a television. In a single household it wouldn't even necessarily need to be an extra television, unless it's some kind of truly abusive household where the kid's not allowed to pre-empt the family TV to attend school. Of course, in a multi-kid household, yes - one screen per kid would be needed. plus they'll need…

Oddly I was at Goodwill and picked up a RCA tv with an HDMI input for $20. It is only 18", but will do for the Pi 400 I grabbed today. Cheap used and still useful monitors are out there.

I was lucky to get a pre-release version to test, and I decided to tear it down before I started trying it out. I posted this blog post with detailed pictures of the insides, and some more details and performance benchmarks: https://www.jeffgeerling.com/blog/2020/raspberry-pi-400-tear... There are also a couple videos linked in the post, if you're more visually-inclined. Fun fact: the Pi 400 (and Compute Module 4) bo…

> Fun fact: the Pi 400 (and Compute Module 4) both have newer revisions of the BCM2711 SoC (C0 instead of B0), and that's part of the reason the clock speed is higher on the Pi 400 (1.8 GHz) than on the regular Pi 4 model B (1.5 GHz)—the newer revision apparently handles faster clocks and scaling with less heat than the older revision.

... and a mechanical keyboard, to complete the possibly unintentional Atari reference.

(Folklore says the original product plan had the Atari 400 come with 4K of RAM, and the 800 8K... and then memory got cheaper by release.)

One thing I do NOT like is their continued reliance on SDcards -- after a while of 'normal' use (maybe a couple of years?) I've found the SDcards in my RPis tend to go south. It seems to be it would have been so much better to just have one USB 3 slot dedicated for a USB3 Flash thumb drive, which could be slipped inside. Another small thing: it would be nice if the kbd had a ThinkPad 'stick' mouse --- which is much m…

"Endurance" SD cards, usually sold for use in dashcams, last a lot longer.

As a British person we tend to tell everyone we do that and people believe it. However it’s not necessarily true. We produced a ridiculously large amount of crap to the point we nearly killed our manufacturing industry. If there’s anything to aspire to its Hewlett Packard’s test and measurement and computing offerings between 1960 and 1990.

I cannot resist the urge of sharing this wonderful sequence (also made in UK :) ): https://m.youtube.com/watch?v=1EBfxjSFAxQ

That show is just so good. “Have you tried turning it off an on again?” is close to a universal joke.

official Raspberry Pi Sense HAT https://www.microcenter.com/product/453920/raspberry-pi-sens... 5x5 RGB LED matrix, gyro, accelerometer, magnetometer, thermometer, hydrometer, barometer, joystick sensor, all for ~$30 USD

Getting the POE hat in there somewhere, somehow, would be pretty neat.

This blows my mind. I know, it's much more incremental than it is revolutionary, but I think the form factor achieves a much greater degree of access for many people than a typical Pi whose bare hardware may be a lot more intimidating. Now, it's "just" a computer, which happens to expose a 40-pin connector for the standard Pi hardware fun. And unlike other options you might find, this has the massive built-in communi…

Back in 1988 or so in Norway when me and my brother got our first computer an Amiga 1000, that costs about $2200 adjusted for inflation. And salaries where lower then. It would have been impossible to buy without a generous "donation" by my grand parents which had quite some savings.

And back then salaries where much lower even adjusted for inflation. That Amiga had 256 KB of RAM. This Raspberry is just a beast in comparison to what me and my brother had and it costs 31x LESS, in a world where salaries are higher than back then.

I can see this opening up a lot of opportunities for families and schools in less affluent countries. Maybe even businesses. I can imagine various famers and small businesses out in the countryside in Africa or India could benefit from a computer like this to lookup market information for crops, plan budgets, savings, purchases etc.
