+====== Important Notes about new PCB designs ======
 The aim of this page is to give the community the possibility to publish improved layouts of MBHP modules. The original layouts by TK are mostly quick solutions with focus on "first-time-right", and therefore not very well optimized with regard to area size or number of bridges.

    * try to let ca. 5 mm free at the borders, otherwise chances are high that tracks will be damaged during splitting the boards to smaller pieces
    * consider mounting holes at the edges
-   * single sided boards should be prevered before double sided boards
+   * single sided boards should be preferred before double sided boards
-   * never use a cracked version of Eagle. Not only that this is illegal, but such version also corrupt the .brd files (they cannot be opened with the freeware version anymore)
+   * It is against the law to use any pirated/cracked software, and this is absolutely not to be done here. If you have a registered copy of Eagle, or a freeware/Eagle Light version, go right ahead. Cracked software is not only illegal, but  will also corrupt the .brd files (they cannot be opened with the freeware version anymore).
+      * Consider Kicad if you need a larger layout. It is open source and free to download from [[http://kicad.sourceforge.net/]]
+         * Not that a larger layout is neccesarily an improvement! ;-)
    * **IMPORTANT**: never change the part numbers, they must match with the schematic to ensure consistency

+====== Ideas ======
+Suggestion from Rowan:
+I've got an idea for a small modification to the layout of the DIN and DOUT boards which could cut down wiring in some situations.
+What I sugget is to change the spacing BETWEEN J3 -J6 of the DIN and DOUT (I guess this would be useful on the AIN too) to a multiple of 0.1".
+The reason I suggest this is it would allow the DIN/DOUT/AIN to be used as "Plug-in" Modules/daughter boards for strip/matrix board that have DIL Sockets mounted on them. I could mount all my buttons, pots, encoders etc on Strip board, then mount some DIL sockets spaced the same distance apart as J3 - J6 on the other side of the board and plug the module directly on to the board which has the controls on it.
