OldBlue Modules (archive)

These pages list the current modules designs for the BugBrand system, all made with 4mm banana sockets. Through 2009 batches were released primarily to the 12 or so core system users with occasional external sales, including some in Minijack format. From the beginning of 2010 all current designs are being updated to Rev.2 status - introducing new and more efficient production techniques (Surface mount construction and parallel PCB designs) and adding a few small additions to some modules.
Note - I never even posted several module designs on here! All OldBlue modules show up in ModularGrid.
