Let’s see, recently:

Home automation fixing

Proposed integrations with some services locally

Science experiments explained at a few levels, finding good background info and where to read up about some safety information

Maths help for specific areas my kids are looking at and proposed games for that

Evaluation of coding options for my kids

How to link up some ideas on coding, electronics and using the home automation side as some fun outputs

LED strip info and work, again integrating with smart homes and what’s good around the kids

Framework evaluations for automation at work and home

Crystal identification

Looking up local council info

Relevant music suggestions for kids to play on the piano

Here some things cross over. I’m happy writing code, I typically want easy open source options, I have languages and tech I prefer, I’m moving g things to matter, I have home assistant, my son is excellent at maths given his age but I’m working more on comprehension of problems, and a lot more. All those are things that with a bit of background info change the types of answers I get and make it more useful.
