Attempt At Custom Controller...

I am starting with a triple clamp assembly from a CBR929RR. Head and fork tubes are carbon fiber. Spacers and steering bearings are 3D printed. I plan on using an hydraulic master cylinder to drive the front brake potentiometer. Will post more pictures as I make more progress.

This will be very interesting to see how you progress with this and how well it will work, Uberslug.  ;) 8)

Is this something your doing as a one off personal project or something your planning to build and sell to others in the future?  :)

Good luck with this project mate.... I'll be following your progress closely.  ;)

they see carbon pattern they go crazy ! :o  ;D
bigger picture/sketch will be more appealing :P
new sim in town ? ping me !

Why not act on a load cell instead of a pot with that master cylinder? Potentiometers are useless. At the very least magnetic resistance sensors are a great alternative.

Hydraulic force and displacement pot wont work well together. You will need to use a pressure sensor (expensive) or load cell (which you can buy cheap)

what about a single pot break caliper (easily compatible with any break lever) with a load cell like people are suggesting. It could be mounted anywhere on the controller.

You may want to speak to DoubleDragonCC as he is guy when it comes to custom controllers! And he is even currently working on a hydraulic breaking system.

P260 Vishay pot 4.45 from Leo Bodnar

Typical price for Tranducer 14.00

Doing tests right now for how transducer feels in gpb but problems with how to ship with brake fluid and not all people know how to bleed a brake unit

I have added the handlebars and brake levers.





Here is my concept for the front brake potentiometer.



The red unit allows one to convert a cable clutch lever to a hydraulic lever. The barrel to the right houses a small progressive rate spring and the rod on the left pulls / pushes on a linear potentiometer. The lever should approximate what one gets on a game controller. I will eventually source a brake caliper and a compatible pressure transducer but I am still in the proof of concept stage.

Great work uber

I have a set of levers both with master cyliders for brake and clutch but my 100psi transducer is giving me problems, think I brike the membrane? I will let you know results as I test different transducers.

Mock up of Shift Switches with Rear Set.



Rethought the brakes and picked up a couple of used CBR600RR Rear Brake Calipers and a Master Cylinder.

Initial frame layout using old 8020 extrusion I found in the garage.



Lean and steering.



poumpouny

wow,  :o, so it will work with counter steering ? have 2 differente rotation axes for leaning and steering ?, wow  :o

Uberslug,
You ever have too much money, too much spare time or too much arms  ;D

Very interesting build anyway !

Nice work man. Can't wait to see the end product.
