Raspberry Pis - anyone else?

No it's not.


 


You're comparing the wrong items.

Raspberry Pi B, 4GB: £54
Raspberry Pi 400, 4GB: £67
 
Been watching this thread for a while.
I quite like the idea of The Pi but why should I "get into it"?

With that in mind;
Please give 5 reasons(or more) of why "I" should start learning and playing about with Pi's?

SK

p.s please understand that I am not berating anyone for playing about with pi's! In fact quite the opposite. Looking at some threads on reddit about Pi's, some folks have really done some interesting stuff e.g building a hallway mirror with built in weather report scrolling across the mirror.
There are three main reasons for having a Raspberry Pi.

1) You want to build an electronics project that requires a computer as an integral part of it. This is small, cheap, and you won't cry if you blow it up.

2) You want to learn something about programming that is ARM CPU specific, as opposed to x86 (Intel/AMD). I do this and can access ARM assembly language instructions via a C compiler (GCC built-ins).

3) You want it as part of a system that fulfils a specific purpose, such as a media server or retro-games console, that requires a Pi as part of it. These run dedicated software that you copy onto a flash memory card, plug in, and use.

If none of this interests you then it's probably not for you.

Tremendous fun too.

I have several Pis, equipped with different OS's. I have mounted into a touch screen display - equipped with a good aerial and Kali it is my "experimental" toy.

I equipped the Boumlets with a Pi 400 as a cheap desktop for school work (and heard cries of "Scratch!" when they saw the stuff it came pre-packed with.

I have a Pi 400 for myself, as a pure "want not need". My work mates are utterly fed up of me wittering on about the educative and fun applications of it (whilst also probably changing all their passwords around me).

This makes a fun read too


I haven't spun up the arcade retro yet, but was talking with the other half and chuckling about retro gaming; and now seems a good idea.

Something for the school "blended learning" week. Couple of bits about Pi, Python and other stuff.

 
I decided the camper electrical system was to be controlled by a spare Pi4, web enabled so the android head unit and any phones / tablets could be used for control.

Initially I started in Python with a flask server, a single Web page and some web hooks for manual buttons. It looked crap.

So then I wondered about php. I'd have to learn how to control the gpio from php, but there was more potential. Every attempt was thwarted by the need for wiring pi, which doesn't play well with the 4 bit OS I'm using.

I bit the bullet and looked at node-red. I'm a tippy tappy, command line, SSH coder. I don't do this new fangled visual stuff, especially as it has the devil's language behind it.

It was a revelation. Within an hour I had relays switching from a multi tabbed Web app on my phone. The java script is a bit of a pain, but I've got a 20 year old son to help with that.

Have a look a node-red, I'm impressed.
 
I now have a Raspberry Pi 4 with 8 GB of RAM. I put Ubuntu 20.10 on it, and so far as how it looks and functions I didn't notice any real difference between running it on a Pi 4 or a regular PC.

I've been reading ARRSE for a couple of hours, and the performance is quite acceptable for that.

I've watched a couple of Bloke on the Range videos in full screen, and the performance is adequate. I say "adequate" because it's certainly handling the load, but without much extra margin (based on what "top" is saying).

For browsing the web, watching Youtube, reading email, and the like, the Pi 4 with 8 GB of RAM seems viable to me.

The major limitation that the average person would probably find is that the size of the SD card doesn't leave a lot of room for a large porn collection. For those to whom this represents a problem there are apparently solutions involving external USB hard drives, although I haven't tried that out.

Using the Pi 4 as a desktop wasn't why I bought it, but this was an interesting and educational experiment. I installed it on an extra SD card which I will now put away and keep as it will give me a back-up PC should my main desktop happen to fail unexpectedly. Mostly however I will be using the Pi without a monitor or keyboard and accessing it over the network to conduct tests on.

I thought that people would find this interesting. Here's a screen shot of Ubuntu running on the Pi 4.
