I designed this for demonstrating how a pendulum works in a clock. It's speed can be adjusted by how much weight is on the pendulum. I actually built this to be a timing device but I doesen't last long enough for what I need it for. Anyway I would definitly use it to show off to a science or engineering class the basics of a clocks internal working through mechanical motion. The video above shows how to use it.
Step 4: Body Part 4
Prettry straight forward just build what you see in the pictures. After this step you are done building the body!
Step 5: The Gear
Very important part and also an easy assembly. Make sure that the gray connectors are as shown in the picture with the holes faceing up.
Step 6: The Pendulum Top
Again very important piece.Make sure to put the blue rods on as shown. Broken blue connectors are not required.
Step 8: Motor Assembly
Now the wind up motor is important make sure to pay attention to the orientation of the arrow on the top of the engine.
Step 9: Assembling the Pieces Step 1
Just follow the photos adding the pieces as you go.
Step 10: Assembling the Pieces Step 2
The top pendulum piece must be put on top of the gear and than the axle can go through it.
Step 11: Finished
Congradulations! You are done! If you end up using it drop me a comment so I can thank you.
