[DUG] [Off topic] electronic parts

for building one-off circuit boards I ended up doing them myself as the
price to get-offs is quite exspensive.
the method I use is the following:-

using Sripboardmagic I create my circut if its one I have designed.
I then print it out onto a transparency sheet (has to be a trancparency)
either from a Laser printer or a photocopier, then I clean my blank copper
coated board, then Iron on the circuit onto the copperboard.
This is a tricky process and it takes a few attempts to get the technique
right, but the best thing is, if you stuff it up, you can simply use a pot
scrubber and clean it off and try again.
Once I am happy with it I use Ferric Oxide to removed the unwanted copper.
I found using the photo expose method a bit of a pain.

I generally get bits from SICOM, South Island Component Center
www.sicom.co.nz since they are local and just up the road, but also because
they have most things.
Other than that, I use Farnell.
