The Omaha Maker Group’s space is coming along nicely;  This weekend  saw the arrival of more shelving, tables and other materials;  The space also received its first quadcopter visit; I spent time down there both Friday night and Saturday afternoon, and was very impressed by everyone’s generosity with both their time and their material support.

Meeting topics will be sort of free form, but will include a bit of orientation, some discussion on setup (which should be easier now that we’re standing there) and planning for regular operations. By Tuesday, we should be mostly …
