PoC compact sequential shifter

[Jeroen Ottens]

Hi,

I was working on a sequential shifter for my next, next project and, inspired by @Didumos69 his shifter I came up with a compact version of his mechanism that fits inside a 5 wide central column. Here is a short video to show it's working:

Feel free to use it if you think you can use it.

EDIT: Sorry for the bad quality of the video, it was a quick shoot on a rainy afternoon

Leg godt,

That is so compact

Great job on making it so small!

I was able to reverse-engineer it from the video so I made an LDD file: http://bricksafe.com/files/Offroadcreations/jeroen-ottens-/Jeroen Ottens Shifter.lxf

I think I will in an upcoming MOC.

EDIT: Tried to fit it in, but I can't find a sequential gearbox small enough to fit.

Very nice and useful implementation ! And the 90 degree limiter is very original too! Btw, I tend to refer to the main principle as a planetary knob wheel shifter lately, with the two knob wheels and two half pins being the core parts.

Are you looking out for a way to add a return-to-center to the shifter or is that impossible? I reckon it operates already quite pleasantly despite having to return it manually.

Made a 4 speed gearbox...

Thanks! This might be exactly what I need! Would you mind adding a link to the LDD file?

Incredibly small useful thing) Thanks for sharing.

Please test if they're in the correct sequence before using it though. I haven't tested it myself. I don't have the 3L driving rings anymore, and I don't have the smooth axle connectors at all.

I think your gearbox is too compact.  The 12T and 20T gears prevent the "steppers" from moving, so with this setup the gearbox will remain struck.

The only requirement is that gear 1 and 3 are on one (left/right) side  and 2 and 4 on the other. You can switch 1 and 3 by flipping the (ox)-paddle on the same side. Same for gear 2 and 4.

@LvdH Thanks for sharing this, however I don't think I can use it because of the small scale of my car. Thanks for the effort though! Works great, however the indicators would be weird, like 21

if you were looking at it from behind the engine.

May someone share a pic of the internals please?

You have the .lxf file, just load it up in LDD and have a look yourself

The video is no more available...
