I buy a lot of cheap "DIY Electronics" Kits on Aliexpress put them together, the more confusing the more fun it is. But I write up better instructions and observations so if students want to build the same kit they can.
Some kits I do not tell anyone about because they are terrible. But really? Most of them are great. If you don't mind reading a datasheet or doing some detective work.
But I think blogging about "Kit Adventures" might be interesting.
It's amazing the fun you can have.
