I have yet to document and put up the board design I am using as it is a
work in progress.

The techniques I use to make PCB's at home I have already documented here:-

http://aka47.adsl24.co.uk/serendipity/index.php?/pages/sspcb.html

This is where I will also document the minimalist microcontroler board
design I am using. It is a single sided PCB easy to make at home.

Most design work is sort of iterative in that I do a design and then try
out making it to discover where I did something wrong. Followed by
modifying the design and then trying it again until I am happy with the
end result.

The design itself is OK I am just iterating on the PCB layout to get to
something that is easy for other folk to work with. It is nearly there.
I am just making some of the pads a little larger to make it easier for
learner solderers. Then I can Document it and put all the files on line.

The need to enlarge the pads was something I found when building up a
pair of 644p boards to take the 1284p devices. These will be set up at
the full device clock of 20Mhz.

The version of the PCB when I put the details up should be 1.2 (1.0, 1.1
are the previous iterations).

For etching I use the Copper Chloride method documented here :-

Sorry I am not big on video.

But hope these help


Cheers
