Scene tag

- press A and D to change gears
- 4 speeds
- entirely mechanical
- +inf friction circles instead of gears for stability reasons
- stretched hinges used instead of driveshafts for lag reasons
- don't press both buttons at once
- info on the right
- should be played at 100hz

Made this last night. My first successful stable mechanical gearbox.

This is awesome! I love that there is someone who is doing some mechanical stuff.
great mechanism!
Wow! The mechanical complexity is amazing, and it works quite well! Great job! :tup: _o_

By the way, WELCOME BACK to Algobox! I hope to see more of your new scenes again soon!:)

This scene looks great and works quite well. The scene is fine without any changes, but I have some suggestions:

1. The indexer has (4) large blue wheels; (2) left and (2) right. The left pair are comprised of (1) driver and (1) driven and are connected by (1) connecting rod. (3) equally spaced connecting rods connecting the left pair would work better. The (2) additional connecting rods can have no collision layer. The reason for the additional connecting rods is to push the driven wheel when one connecting rod is at top dead center. You can also get by with just (2) connecting rods if the second connecting rod is 90 degrees out of phase with the first. The discussion for the left pair also applies to the right pair.

2. The indexer works like a rack and pinion. If you turn off all layers except for layer A and run the scene you will see the fit between the rack and shifting forks is quite tight. If the shifting forks are replaced with frictionless circles and the rack has some lead in angles cut into it, then the movement will be much smoother and the scene will run at 60 to 1200 Hz.

3. The flux capacitor that is set at 3 needs to be set to 7 for better performance.

Cheers noonan.
I just wish you'd posted it an hour ago, when I wasn't halfway through my next project (operating on the same principle):(

But seriously, thanks. There's a huge lack of specific, constructive criticism in Algobox, and that'll be useful for improving the NEXT GEN models!

This deserves 10/10!
It works perfect in 2.0.2b15 btw.
Its very cool, but how did you make this stretched Linkages? Everytime when I try it the Balls get pulled together:(
@ Nub Nub
Open the script menu for the stretched hinge/axle and change "hingeConstant" to "1e-030".
Glad I could help.:)
Nicely done gearbox, with little modifications it should be possible to make it fully automatic.
^ I've thought about that, but I'm not sure how to implement it with this design. If you've got any good ideas, PM me. I'm stumped.
