A mechanical piston, wheels (or ~~cam~~CRANKshaft) drive shaft, which drive piston.

EDIT: like in a car

erm, a crank?
That has already been made

~~Then I say computer controlled. I've got nothing else to offer~~

EDIT: I found this: just reverse the design:

EDIT 2: this page on wikipedia: http://en.wikipedia.org/wiki/Rhombic_drive

that still requires the cranks to be impractically huge for a lift this size

What if it were flywheel-controlled (and just shot up the shaft?)

Sorunome · « **Reply #80 on:** June 29, 2013, 11:35:57 am »

erm, shooting it up? Impracticle, to heavy
flywheel? what is that?

pimathbrainiac · « **Reply #81 on:** June 29, 2013, 11:40:38 am »

Then I guess just computer control it. I can't change my vote, though.

wierd.
Well, any kind of launching is too impracticle due to the big weight, and cranks are also impractical due to the tall height, so it would require some mechanism to mechanically change direction and my current one decided to stop working, so....

If only K'nex had engines/motorized stuff that worked based on boolean logic and stuff, maybe a K'nex calculator would be possible (like Minecraft calculators)?

There have already been made knex calulatores, but only for adding numbers, working purley mechanical.

So yeah, even though that elevator lift is still unresolved, i still did progress in other parts of the machine with some lifts.
I especially like how the ring lift is just so empty in the whole
As always, pics are attached.

I got AWESOME news, thanks to a AWESOME knex'er called Shadomwn39 (how is actually a good friend of mine, but i never met him IRL

) I managed to fix the elevator lift - well, more that shadowman told me a idea he used in his, because we two are inventing the same lift at the same time :O

So yeah, now I need to make the balls exit

Pretty cool to hear !

Was there something wrong with using a motor+knex chain system for the lift?

erm ,you mean isntead of using the string a chain? It wouldn't look that good IMO.

And the problem is pretty hard to explain, sorry, I wish I could.....but the mechanism is so dence that I can't even take decent pics of it to help me explain, so meh
