Extensible reconfigurable media appliance for security and entertainment captures images digitally for storage. Each of the first and second modules have at least one of a motor and a fan wheel operable to generate a flow of fluid into and out of the exhaust fan. The particular semiconductor structure may be fabricated using a self aligned dummy gate method that uses a portion of a spacer as a self alignment feature when forming the spacer shaped metal gate, which may have a sub-lithographic linewidth. A connection interface detects when the feature module is engaged with the upright section and the predetermined utility set required by the engaged feature module.
