Proud dad moment here, but also a realization about the original topic.
First, my 5 yo daughter was soldering her first chips to a board yesterday! I soldered two corners to show her how it's done, then she did all the rest while I held the board down. I think she did really good for a 5 yo!
But I learned something from this: Any kid who doesn't know a lick about soldering or what is expected will do very similar stuff, or worse. Look at how the solder went right through the hole onto the top of the board even! This could happen to a kid of any age, even high school, or adult "kids" I suppose. I think it's not just skill but expectation. "I put it onto the board, it should work immediately, right?" Wrong. And what if the chip orientation was backwards, ah! No repairing that!
So, with this, I am closing my mini-dream of a making a solder-it-yourself kit for high school kids. Without supervision/instruction, prior knowledge, or immediate feedback, something small like a 4"x4" board is far too much to expect from a complete novice. I think kits are great, and I know high school or even 1st graders can be *taught* how to solder correctly. But to be taught means they need an instructor, a master, and not just a book (or some youtube videos). Folks like me who learn how to solder on their own is mostly done through mistakes and self-projects, where if I mess it up, I'm not out anything for it and no 'technical support' was ever expected.
I think this ended up being an imagination vs. reality conflict. I just imagine that everyone else out there has the ability to self-learn, but in reality many folks, young or old, are not able to self-learn without learning how to do that first through a instructor. [ I guess that's why I have a job as a math teacher after all. ]
There's my conclusion. Thank you everyone.
