VR FlightSim

keep in mind, this is "short throw" stick design. Anything like cyclic or "floor stick" is absolutely different story since u have much more room to hide your mech's..

going this way I would have belts on the first reduction (5:1 at least), then gears_to_motor.. (for minimum play in the stick)

those gears are just visual clue, you can mount whatever u want on the axis.. :)

Hey boys Here's an inspiration for "short throw" FFB gimbal. -Drawn and tested in Fusion360 (motion study) -Works really well in the simulation..

Good morning boys:) MetalGear Honk don't forget "Friction". That's what simulates wing mass and cable load. "Damper" just kills the force when you let go of the stick so it won't overshoot the center resulting in shaky dance. Other than that, your list has pretty much all we need.. How would you guys feel about Trim system that has actually nothing to do with the sim it self but only moves center of the "spring load" on the stick. We would need to include such function into the script or windows app so we could control this with Hat switch or external axis (physical trim wheel). This is how it works on my yoke at the moment and trimming by "feel" is a breeze;) Jay

well you don't have to disconnect A/T mechanically. The slip clutch in the video provides natural friction on the levers when the motors are not active and as soon as you engage A/T and let go of them, they will follow the A/T. In conclusion I would suggest to program "disconnect" function into firmware that looks after servo circuit (dc motor - hall sensor/pot) Something like [when pot reading and motor position differ for more than ? sec = A/P disengage] Jay

@ MetalGear Honk The motor shield is Due compatible. Have a look at the diagram pic I posted and imagine you move the shield straight down on top of Due. Mounting holes and pin layout is identical. Regarding the "cross" gimball STL you were asking for.. I don't think it's worth the effort to struggle with 3D printed version as it is very delicate and precise mechanism requiring some level of rigidity and since you have workshop available I would suggest to go for metal solution right away. I can draw a 3D model, verify it's functionality and share it here if that helps.. Jay

or this one.. (cheaper)

@crow0827 I don't know much about DCS interfacing but having done lot of similar toys for other sims I would suggest "slip clutch" and DC motor. Something like this (3:30 into the video): https://www.youtube.com/watch?v=zudKaqFBl2s

As far as my investigation goes, the L298N dual motor H-bridge is quite popular within arduino devs. However I would prefer to have sort of all in one package of OSFFB so I would like to experiment with motor shield like this one. https://www.makerfabs.com/index.php?route=product/product&product_id=132&search=Motor+shield

@ MetalGear Honk since OSFFB uses win driver, how do you target the effects? Do you "play" the existing effect or you creating new one? Jay

Hey Christian Yeah mate, thanks for the link, this is it;) Hope we can pul it of reasonably soon..

I beleive that windows recocnise it as a generic FFB device. All described in MetalGearHonk's code on his pro micro.

I know it will work without the software but in my opinion it is important for two reasons. 1. easy to preset and save individual parameters for different aircraft and sims. 2. Trim control of the physical axes. This would be essential for good force feedback device. Did you have any kind of trim in your code already? Hall sensors are great, just not sure how they gonna cope with magnetic fields from DC motors though. Regards Jay

@ MetalGear Honk cheers for sorting the post mate. I didn't have anything in my out_box except the very first message. Don't know why. @ everybody Hey all I wanted to share simple diagram I drew just to make sure we're all at the same page. Please let me know if you spot any flaws in this concept. Regards Jay
