If I had a young teen, this is something I'd think about, as it seems like an excellent way to encourage someone to learn technology, beneath the cover. I might discuss it with my grandson's father. It's a little pricey, but probably worth it if it could be afforded. Thimble.io is a subscription program that ships a new project to be built or assembled each month, including such things as WiFi robots, LED cubes, compasses, light switches, with online tutorials, step-by-step instructions, and an online forum where kids can discuss their projects. The value isn't in the complete thing that they build, but in having built it, as they may include soldering, programming, etc. Kids are encouraged to hack the projects which, used in this way, simply means to enhance them, or make them into something other than what was intended.
I looked it up and came across this sort of review. I was going to recommend it to my son for the youngest grandsons but the oldest one there is only 12 and isn't that patient. https://the-gadgeteer.com/2017/01/25/thimble-wi-fi-bot-building-kit-review/
Yes, I agree...that's why I looked further. I think the 9 yr old grandson would be the most into it...once he's a little older.
