If you have designed any lift/element hybrids, contact me and I'll add them!
Guide to all Knex Ball Machine elements: https://www.instructables.com/id/The-Official-Guide-to-Knex-Ball-Machine-Elements/
Step 1: Half-turn
When no balls are in this element, it hangs with the weight pointing down. When balls are added to it, it flips over, raising one ball but the other ball is lowered even more.
To make your own, copy the pictures.
Step 2: Quarter-turn
Step 3: Bump
A simple element where the counterweight of the element has a ball on it, which gets 'bumped' up when the element is used. It usually only goes up 1 blue rod but is effective when your design goes wrong and the ball ends up a little lower than it should.
Step 4: Stepper Bumps
By combining the previous element with the stepper lift, another lift-element hybrid is made.
To make this, copy the stepper lift then modify the top for ball arms.

Step 5: Ratchet Arm
Another lift/element that uses an arm, but this one is attached to a small wheel lift via gears and a ratchet. See the pictures 6-9 for ratchet instructions.
Note that the first picture is not the same design as the rest of them. I included this picture because it shows all the mechanics.

Step 6: Quarter Arm
Inspired by an element in Project Concatenate by Yardking, a ball goes on the arm at furthest leverage, pulling it down. A second ball then rolls onto the arm while the arm resets, resulting in that ball raising.

Step 7: Weighted Kick
When a ball enters this, the arm presses in, then 'kicks' up with the ball on it. The ball then rolls across the top. A separate ball goes on an arm to reset the lift.
Step 8: Jigsaw Lift With Added Element
The Jigsaw lift has two parts of it's rotation: half a revolution moves the ball up, while the other half resets the lift.
The extra element replaces the motor. It uses the ball's weight to do the hard part of the lift, then gravity resets the hybrid. An example of this hybrid is found in this video: http://youtu.be/lSuJbo9xtLY?t=37s
Step 9: That's All!
I hope this was inspirational! Please send me any new designs for a lift/element hybrid, and I'll add it to this list.
