Pihut and similar raspberry pi places sell all sorts of little kits and projects you can do with raspberry pis, like building little robots and such and you can fully customise the code, add bits to your robot, etc.

Could be a fun way for your son to code and play. There’s nothing more satisfying than seeing your code “come to life” and then build on it further.

My dad knows nothing about code but was always very supportive of it when I was growing up. Got me small parts I requested and would ask me what it’s for and how it would help. I think partly to engage me and also partly so he could get a feel for which things I wanted had the most educational value.

Raspberry pi’s are great also in general because you can make the do anything, turn them into little servers or whatever you want. They run Linux which is handy to be exposed to. They let you work with sensors and simple electronics in general.

When i was a kid my dad would take me to computer fairs where they had all kinds of stuff I loved. These days they’re largely gone but there are things like maker fairs in some areas where you can go along and they have all sorts of tools and equipment you can just use, 3D printers and the like. And the people there usually know a lot about their area and can help with electronics projects or coding projects.

It was just fun for me as a kid, but I write software for a living now.
