It all boils down to.... how fast is he able to learn new things? The recommend age is just a suggestion for the average person.

Start with really simple circuits and see how long it takes for him to understand it. Some people learn faster than others. Some have the ability be a genius in one task or subject and be totally helpless in everything else.

I rebuilt my first lawn mower engine when I was 8. My dad was an airplane mechanic in the USAF. I was in my mid 20's in collage before I finally figured out algebra and then physics.

In the end you will have to be the judge of how much and how fast he can absorb the information.

Snap Circuits are fun. We got a set for my oldest a couple years ago (now 8). My 3yo likes to join in - probably mostly to annoy his sister. It's a fun, easy place to start on logical circuits and really hard to mess anything up.

 

It would be fun to add an Arduino for a bit more capability.

Jason Marsh?, I think back to what I did as a kid and remember all my u documented experiments, that's why I want to teach him the rules of the road as soon as possible and give him an outlet that will result in fewer instances of things being ripped apart.

As long as he's not using a loose appliance cord to "power" things like I did he should be fine. Oddly enough, I survived all my adventures without injury. Well, there was one burn from a capacitor. My brother and I used to charge them up, wrap the leads around the sides, and then toss them to unsuspecting friends. It was like a hot potato game, sort of...

Never had any mishaps like that one, but I did have a hydraulic pump that wouldn't shut off after turning it on. Had a thermal breaker on the armature. Brush debris formed a bridge between motor windings and the breaker wiring. Once energized it would run right past the high pressure limit because it was powering it's own relay. Had to cycle power off for the whole tank to stop it. Pressure relief valve got a good workout somewhere north of 4000 psi or so.

 

Sarge thought I was off my rocker when I brought the pump in to service it. He thought there was no way I could be right, insisting the pump couldn't make itself run.

 

He shouldn't have questioned me. A year later the tables were turned and I was his boss. He was on the phone with HR and got himself reassigned pretty quickly 8^)
