    Default DCSSR PCB layout available?

    Is there a PCB layout for the DCSSR (I think v1.1?) available? Just bought a jug of etchant and wanted to try making my own. I looked on the Wiki but didn't see it there (I've PM'd wjohn also).

    Thanks!

    I went looking previously and didn't see one, which is why I spun a version in Eagle, and posted the layout to the "Files" section.

    NOTE: I haven't built /tested it, as I don't have my REN boards yet in order to drive it.

    Hey Thanks LabRat - I was about to try my own layout but why reinvent the wheel! It looks like it would be an easy etch project for sure. The only thing I might look at is changing the mounting hole pattern for the Keptel 200 enclosures (I have a dozen or so laying around).

    The hole patterns were posted by RPM in this thread for the TA-200, CG-1000 and CG-1500 enclosures:

    Looks to be a 1.4" x 1.0" pattern.

    Thanks again!

    FYI.. the discussion on the design is here, which might explain why
    some of the routing looks a bit odd.

    http://doityourselfchristmas.com/for...ead.php?t=7573

    The main thrust was to keep the POWER vs PC (or micro) sides of the opto-isolator, as isolated as possible (so no cheating by running traces under there) ;)

    OK - The only thing I had to change was to rotate/move the 7805 and then I can place 2 holes at 1.4" straddling the Opto. Should be plenty of room for the screw head (#8 or #10 I believe). The only thing I have to check is if the board will fit into the enclosure when screwed in. Unfortunately there's a couple measurements missing from those links so I'll have to make some manual measurements at home. Two screws should be fine to hold it in the case.

    I'll post the updates when I find out.

    Thanks!

    Print it out on standard paper, cut it out, and test it to fit. Believe it or not, I hadn't considered this until I had seen pictures of people doing it in these forums. (Ya learn sumthin' new every day)

    Hmm... one thing I noticed when I printed out the etch only was that there would be very little copper around the pads on several of the components. As an example, I looked at the RJ45 jack which is from the AMP (con-amp) library. It has a pad size of "auto". If I change that to .06 or so I get a reasonable amount of copper w/o shorting, etc. Now... I know the "auto" setting must mean that it can automatically set the pad thickness based on some parameters or something - so - you Eagle experts (I just started playing with it about a week ago) - how do you do that w/o editing the part library?

    Thanks!

    I etched a board on Sunday using those default settings, and it turned out just fine (well.. fine at the RJ45, I had a couple of breaks in some traces elsewhere, but that's a different story)

    Making those larger may impact your ability to get decent clearance around them when running traces "between" the pads (though I'm not sure if that applies on this board).

    Did you manage to get a version of this Etched?
    (can you share you version back, so I can clone the board layout??)

    I was thinking we could create a library of board shapes that fit various enclosures. (just an idea)
