Question Possible to DIY Activepedal with something like SIMHUB?

I was wondering if you guys think it would be possible to DIY something similar to the Simucube ActivePedal?

I'm oversimplifying here, and I do obviously respect that this is a seriously impressive bit of kit, but as far as I can tell, it looks really similar to a lead screw setup that you might find on a 3D printer.

Again, I am certain it's much more complicated than that, but could it be possible using something like SIMHUB, which people already use to control rumble motors on pedals?

Okay, so, maybe not so much all of the "active" stuff, allowing you to change the feeling of the pedal, but more using a similar leadscrew steup to provide ffb, similar to rumble motors.

So, like a hybrid of the two.

Its an actuator that moves back and forth

It just happens to be connected to a brake pedal to give you a feeling of motion when you are braking

I think there are better ways to simulate motion than through a brake pedal

But it should be possible (and easier) to do the same thing by moving the whole pedals back and forth using a linear actuator

Looks very interesting. The hardware seems simple, basically just a stepper/servo motor, a lead screw, maybe some linear rails, and a load cell (which might not be necessary, maybe you cold just keep track of the stepper's position, and using the force curve you programed into the pedal calculate the force exerted). The software might be a bit more complicated, for the gas it should be simple, it's just a pedal you press, and it doesn't provide really any feedback to the driver. The clutch and the brake on the other hand do, I don't know if sim racing games even provide that sort of feedback data, but they might start now that a large company such as Simucube is making active pedals. But even without the feedback it's still a very interesting DIY project, and for someone like me who likes to tune stuff to the slightest bit, it would be amazing. Also it makes it easier to build the pedals, no fussing with the geometry or springs, just throw a motor and a lead screw in and you are done.

A quick ebay search yielded this:

I will definitely be watching this project with great interest.

Yeah, I don't know if you've maybe seen those guys who are working on the DIY FFB joysticks, but its essentially that isnt it, a single axis FFB joystick.

Perhaps the load cell to let the pedal know it needs to return to zero when no force is being applied?

Kinda like this, which makes use of an openFFB board.

I asked the creator of openFFB if it could work for a pedal and this was his reply, "in theory sure but a new mainclass and support classes have to be written to create a pedal of course."

Interesting...

Yeah, it's basically the same. Regarding the load cell, I'm still not sure if it's really necessary, when you press the pedal and keep it there, the motor is applying a force in the opposite direction of the force from your foot, the forces are equal so your foot doesn't move. But when you let off the pedal the motor still applies the force, and the pedal moves back to the starting position. Regarding openFFB, I don't know what he means by that I am not very well versed with software, hopefully someone with more experience can chime in with that side of the project.

@K120_Enthusiast: a load cell is mandatory as this is force driven.

This might be a good place to start
