8x8 dot matric 3mm diameter

Hi daok, I feel some anger on your answer. Do you think the persons here don´t like to help with newbie things? I´m asking this cause, altough I don´t post too much, I´ve been reading the forum for a while, and I´ve never felt that way.
If anything on my answer denoted I´m unwilling to help, that was not what I meant. (I don´t fell comfy about the construction of this phrase - in the grammar matter- can anyone say if the sentence is right?)
