Ah... one of the reasons I love doing FIRST. A students was shown how to do a difficult task, and then they 'get it' immediately.
These are the current-sensing chips a sophomore student soldered last night, one of their first times soldering too. Every single chip worked, none were overheated and no joints were missed. Only basic equipment was used. We can't tell the difference between the one a mentor did and the ones the student did.
Again, apologies for the cell phone pic.
