Hi forum,

My 10 year old son has decided the thing he wants more in the world is a rasberry pi. I am 10% educated here - I understand kind of what they are, but I’m not sure beyond that!

Is there such a thing as a foolproof kit aimed at kids? I’m sure I could gen up and do this with him, but being selfish - remember the days of sorting drivers, downloading bits and bars and trying to make them all work from DOS / early windows in my youth, and it’s pretty much the last thing I want to do on a weekend now!

I double don’t want to have to spend ages trawling the web before even embarking on a Linux learning curve..

So if I can find something he can be self sufficient on, then I might relent and let him get one. If not, there are a lot of other father son things I’d rather be doing wink

Thanks in advance..

what does he want to do with the Pi?
I am sure he's deep in the world of YouTube and HowTos. It's not hard....also if he wants to connect to things and use Python to build out systems, that is interesting too.

don't be his anchor biggrinbiggrin

Buy him a Pi, a decent SD card and leave him to it, plenty of YT resources etc for him to get stuck into and the worse thing that happens here is he gets an interest in STEM and a career.

Was looking at this for my 13 year old:

More than one SD card, as its nice to have a card all set up and one to mess about with especially when you are learning. Although these days with the cost of SSD drives it may be wiser to buy an SSD or 2 as they are far more robust. Don't need a lot of space.

I am not 13 but can I be your child for the purposes of this? hehe

Have a look on eBay for a Kano Computer kit (they don't make them new anymore).

Eg https://www.ebay.co.uk/itm/115984187356

In the absence of a link for what he actually wants, here you go:

https://thepihut.com/

They're just a cheap computer that runs on an SD card. Like others have said, depending on budget get one and an SSD for him to set up on as the SD cards can fail.

If he's reasonably bright and has internet elsewhere, he'll have no trouble.

This 4B starter kit has everything but the SSD... https://thepihut.com/products/raspberry-pi-starter...

Pi Zeros are much less powerful and typically designed to run specific functions, Picos are primarily for even more specific automation, it is the non-zero and non-pico you're probably wanting.

The starter kit has an SD card that will install the OS however he likes - you won't need to trawlnfor drivers or anything. Personally I'd get the SD, copy it on your PC and keep the original for when he wants to start again...

Quick question re raspberry Pi pico...

The pico has many GND GPIO pins. I will be using several inputs and outputs, can I connect all my incoming and outgoing grounds to a single ground on the Pico or could that potentially overload the current into that single GND? Am I better off giving each input/output its own GND connection? Are all GNDs connected on the board or are they separate connections to the CPU?

Also as I test things ideally I'd like an oscilloscope to see GPIO hoing high and low etc when I want them to, in the absence of an oscillscope what is the cheapest way to see what is going on (some will be going faster than my multimeter could monitor)?

TIA

Ground often go to a plane, and usually they will be commoned together unless there's something odd going on. Unlikely you'll overload anything, but it's usually easier to use multiple wires.

You can check the actual PCB design files if you want to be sure.

For testing a cheap scope of some flavour is usually easiest, they can be very cheap these days.

Otherwise you could think about driving some LEDs as they're a fast reacting way to see a pin state.

Many thanks, appreciate your comment.

I have hankered after a scope for decades... maybe now is the time to get one... Might try getting a second hand 2 or 4 input Tektronix like I used as an apprentice many years ago.

Juat buy one of the cheap 2 or 4 channel portable battery powered scopes on Amazon, they work fine, if you need something a bit better maybe look at Picoscope stuff. No point spending out on Tek stuff, it is good but expensive. The old 400 series scopes were so well built they are probably still around today but probably no longer repairable as so many custom parts including resistor values.

With respective to grounds, for something like dgnd I would use the nearest adjacent gnd but when using an analogue inputs you need to use the correct ground to avoid unwanted noise issues.
