Michael 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 :- http://www.instructables.com/id/Stop-using-Ferric-Chloride-etchant!--A-better-etc/ Sorry I am not big on video. But hope these help Cheers Andy Kirby On 22/08/10 18:51, Kalus Michael wrote: > Hi Andy. > > I'd realy like to take a look over your sholder when you do "built a > couple of boards up" - video?
