plug in the “Smoked” arduinos to the computer and next to the USB connection are two small IC’s. put your fingers on them. After just a few seconds they should get very hot. at this point, unplug the arduino. If those ic’s got hot, then what happened is that you put too much current through the regulator. you can change them out (see my video on doing that under “random/off topic”) and your arduino is good as new. it’s fairly difficult to really destroy the arduinos because the regulators should fail well before any permanent damage is done.

I think it’s called “how to solder SMT or mad soldering skills” or something like that… I’ve fried a fair amount of regulators and have yet to really destroy an arduino…
