Looks like shimano is using stepper motors, that will give a little advantage because the motors can be very small and at the at the other side they work differently so to make a 360 degrees turn some motors have 6 to 20 steps...

Servo i read it somewhere a few days ago. And kind'a make sense because shimano set up is pretty small after all compared with the mavic one for example.

Sweet!
Although why you used those awful Molex plugs is beyond me.

any video's of the working proto's (not on the bike). I mean when you push the buttons are the servo's working properly. I think something like this is awesome and just enjoying the progress..

I had to take the servos off the bike this week, while I worked on the electronics. But I'll be putting them back on soon; so I'll take some additional videos then.

Molex connectors working is one thing, but for how long? There's a lot of moisture, other environmental cr*p and vibration on a bicycle. Connectors for inside a computer are not designed for that.

I think that's the whole 'work in progress' thing. I would hope the OP would consider a waterproof final version.

It's really been fun watching the development.... who knows, the OP might rival Shimano a few years from now

Awesome. Job well done up to this point, and I can't wait to see the final product (These shifts looked great)
So what else have you invented, re-engineered

I love this idea, I'm adding to my bookmarks, if that will work I'm building one myself, I have about dozen servos and electronics from my RC cars and heli. It is such a cool idea, at the end cover in carbon water proof box and put white X sticker on each. Love it

Also, I know it might be a little late, but I have lot's of older parts, especially derailleurs, that you might be able to use for your experimentation. I'd be willing to donate some, and possibly a set of unused RC airplane wireless servos and controllers. They look almost identical to what you have there. Might be good for some wireless experimentation. PM me if there's anything I can help you with.
