Homebrew PCBs

i'm sorry for late reply, i got my mails end up in spam filter, i've 
just noticed and released it. sounds like another solution for me, and 
thanks for that :), i was trying james sugestion and have an adequate 
results. i'm getting better with this thing :). i'll take a look on the 
video.

anyway, i saw some dry film not rolled/curled back (stay flat). i was 
using dry film that rolled back after cut. that was a problem too, 
especially when separating thin plastic part from polymer (i used tape 
on both corner side). but i think i just have to make more practice..

thanks for all your supports guys :)

regards
hari
