DS is 10, and is at a stage where he's awkward to buy for - he's outgrown a lot of toys now, but we're not prepared to buy him tech, so it's hard to think of presents for him. He also doesn't particularly want anything, but obviously he can't just have nothing on Christmas morning (he wouldn't be interested in money, either - he'd put it in his bank account and leave it there).
He does like Lego, so I'd wondered about getting him some of the Powered Up stuff, like motors etc. I just can't figure out how it works though. On the Lego site you can buy motors, controllers, lights, battery packs, sensors etc, but I don't understand what he'd actually need in order to motorise a car, for instance. Do I need a battery pack, for instance, or do some of the components have their own battery compartments? What about the controllers? And what are the differences in the different motors?
Basically I think he'd enjoy having a little motor that he could add wheels to, and if it came with a remote control he'd love that too. He'd probably also enjoy adding lights and things, but we can always get him more bits next year if he takes to it.
Any advice?
