I was wondering if anybody knows of anything online where faults are presented in circuits and you have to diagnose and repair? When playing with the different circuit builders/simulators online (some are impressive) I wondered if something like this was out there to brush up on troubleshooting skills?
Thx

 

That's kinda what happens on here.

I get it. And, for the most part this community is really, really helpful. Just seems like someone has to have developed something like this. Most of my learning is dialogue online, books and HANDS ON (some school college in there- meh). Probably the best way, honestly.
Aside from the basic learning tools for schools, something like this would be challenging, knowledge building and even fun(to me).
