Many thanks for your submission. Unfortunately, the client has something against blue.... it was mentioned in the brief no blue :)
Also, this logo with the rainbow like assortment of colors, to me says something like "I am printer" or "I sell paint", which is not exactly what the client does.
But overall, nice graphic quality and font work, just not in the right direction.
Could you please try to make the top part of the pictorial in front of the SAM7 a single color block ? You may use gradient if you want to try it, but no "rainbow" effect (but a simple unique color such as darker orange, or dark grey could be nice).
