A bit more off thread, sorry!
I think you underestimate just how little English he understands! It is amazing he manages to understand us, let alone try to converse. He doesn't want to break into an English forum speaking Spanish so he will just plug on as best he can. It's a pretty vertical learning curve, Lasers and English simultaneously from zilch! He knows where he wants to go and if that includes shimming up the north face of the Eiger en route then so be it. Admirable really! Despite being a little crazy (so he is in the right place here ! )
Just imagine it's a microsoft opsys giving you cryptic messages about a non-functioning UART but in Spanglish. LOL
Cheers
