Since they like Lego, could you get them into Roblox or Minecraft? MC you can teach them some basic comp sci/computer/tech things using red stone, and there's a peaceful option if you/your kids aren't into fighting in the game. I haven't used Roblox personally. Another option is if you play games at all, introduce your kids to mods. At that age, I played video games with my dad/watched him and doing things like silly graphics mod replacements (turn Mario's sprite into the poop emoji!) help instill the concept that tech is built out of systems and components that you can change to get the results you want. It's just that since they're 3 and 5, what they want is likely to be quite silly.
