Dsm posted updates on his “clamshell” yabp case design for the Bus Pirate v4.
Instead of the screws I had been using, this version of the “clamshell” yabp case uses neodymium magnets to hold the top case and bottom case together. This change should make it easier to open and close the case (no lost screws or stripped screws holes). The same configuration can now support both the Developer use case and the User use case (see the yaobls discussion thread for more details). The four 2.8 mm PTH mounting holes will need to be enlarged with a 3.2 mm (0.126″) or a 1/8″ (3.175 mm) drill before this scheme will work. I believe that the top and bottom conducting layers are at the same potential (GND) so no insulation will be required around the magnets, but there remains the question of whether the removal of the PTH top-to-bottom conduction path at the mounting holes will affect the electrical behavior of the circuitry.
