In 2006 I completed an initial build of a Jensen 51 replica starting with a mid 60's Jensen 50. It turns two AC generators and one DC generator (stepper motor) which in turn light 5 lamps and one motor mounted on the 51 replica itself.
Last year I moved this engine and accessories from a basement workshop to an upstairs bedroom/office with easier access, better lighting and a built in exhaust fan. With the move to it's new location, I connected 6 external/DC powered accessories that run off the 51 replica. These include a Carousel, Ferris Wheel, Plasma Ball, Windmill, N scale train and a Marble Machine.
Despite a balky Marble Machine near the end, everything worked and I made this video in one take.
Enjoy,
