Electronic or mechanical kit for DS age 12

[EightToSixer]

DS has been talking about how he made a circuit board with solder and LED in his DT class at school. I'm looking to encourage this with him with some bits at Christmas. He does competitive sports 4+ times a week, but otherwise is glued to Fortnite.
What gift could I add to his Christmas presents, I would normally look in maplins but that is now gone.

It's not so much electrical but a nice idea to convince him to get off fornite and learn in the process is microbits. You can buy a kit for him and he can code it to do cool stuff. He could, for example code and all singing remote controlled car!

I have a few suggestions from things I have bought my son over past few years:
John Adams Hot Wires
Littlebit R2 D2 Droid Inventor Kit
Robot arm kit
Haynes Build your own Jet Engine kit (do other kits too)
Snap Circuits kit

Thanks everyone, I'll look into all those
