Too busy for the last week, being tired every night and passed out right after dinner. First I have learn how to change a 110v(home-use) motor to a 220v(industrial use), because one of my customer required to have a lower price but for a company, so I tool a home use swing machine but changed a motor that could fit in a big company, usually a company use sewing machine requires more power. And today I have sent 3 different kind of sewing to a new altering company, they do help customer to sew their clothes in order to fit them, and they asked for a current source specially, it was not the kind we have at home or any company. I spent more than an hour at his company and help my uncle to make it right, and finally I got it. By the way those machines we assembled last week, it really was a long week and a lot of work.
