Where I work we use a lot of Allen-Bradley digital interfaces and industrial control systems. My son could probably use to speak their language...he’d really enjoy that, too.

I would encourage him to learn Pro/E. It's the most, or one of the most, common computer aided drafting program. They have student editions, and there are text books.

Then, a Mechanical Engineering degree. Combine those two, and you have someone who can write their own ticket. He can contract at $75/hour +/-.

Also, practical hands-on experience can be invaluable. Like the guys who helped dad rebuild an engine, or the dads who helped build the kids first car. Mom must stay patient - as the men will spend long hours in their "cave".

Encourage his interests.
