Dear Nazirdigi , Its very good that you are sharing these pcbs to forum , but problem is that ,we don't know any thing about these projects. does these are tested and tried ?does these are your work or copied form anywhere ? does these are copyright free work. So please friend share some more details to make them much useful.
thanks
sudhir
