Machines still exist, however vehicles are very, very rarely seen thanks to the lack of fuels and oils to maintain them. More frequently, people use horses, their own feet or Gypsy like Caravans for ground travel.
Air balloons and dirigibles are used for air. Why? Because they're safer to travel in and airplanes are no longer available for use. Dirigible captain's and crews are more frequently recruited by traders to ship their goods across far lands with other trading posts.
Guns still exist, as well as swords and blades. Many people have made a great trade through making such things for protection, including their accessories like bullets and sharpeners.
Electronics still exist, as well as batteries and lights. Though now their energy source is through windmills or solar power paneling.
