DIY 3 DOF motion sim testing around Suzuka

[@uno6504]

What exact motor and gearbox did you use? Do you have a link?

[@murky3787]

You should add vibrations. with that you could have a good feel of the terrain. i think that would be cool

[@mikeyearly]

I do! There is a DIY 'buttkicker' under the seat to simulate engine rpm, gear change and road detail

@@mikeyearlyFuckin nice bro

[@murky3787]

Is there a way I could buy the blueprints for this build or do you not sell that

[@mikeyearly]

@@murky3787 sorry don't sell the plans, just full kits. Would also be cheaper for you in the long run

This is amazing work. Will there be an upgrade route from your 2dof to your 3dof model? I see your links at mantis and am very interested, just wondering whether to wait or not.

[@mikeyearly]

Yes the current 2dof is fully upgradeable to the 3dof. Saying that, I'm looking at simplifying this even further by standardising the design so it's even easier to upgrade. The 3dof is maybe 1-2 months away. Final testing has been completed, I just need to create the assembly instructions and order in some of the new parts

​@@mikeyearly how much us dollars are we talking for a full kit?

[@mikeyearly]

Aiming for around the $3850 mark.

WOW...that's a big improvement from the wood-2dof. More responsive. I was planning on a 2dof, but now I see your 3dof fully suspended and I like it very much. Can I ask a couple of questions? 1) which worm motors did you use: I see they manage your weight very well. 2) do you know if the controller can use the movements of the cars instead of the accelerations? Indeed, I think that is better that the platform will replicate the roll, dig and heave of the car instead of use that movements to replicate the accelerations.

[@mikeyearly]

Motors are 24v 400w with 1:60 gearboxes. The game outputs all telemetry data and you can choose which ones you want to use. I mostly have pitch roll and heave, with a small amount of surge and sway (using pitch and roll of the sim) which feels more like suspension compression rather than gforces

[@TheAngorTube]

@@mikeyearly thanks...according to your experience, do you think that actually needs 400W? could 250W be enough? Because 250W motors are very easy to find (ebike, wheelchair ecc), while 400W are very expensive

[@mikeyearly]

@TheAngorTube sure, but depends what torque they provide which will affect your lever arm length

[@TheAngorTube]

@@mikeyearly fine...using a motion rig, my idea is to feel above all the motions of the car. In example, at time about 0:10, you see the car in the sim have a lot of "shake", but the rig is almost still...obviusly because the gforce are almost at zero. Is it possible to program the software to have those "little" but fast movements of the car...essentially they are the heave. I want to feel the road before the gforce. From what I see on the web, all the motion sim are based on the gforce.

[@mikeyearly]

@@TheAngorTube of course, you can just turn it up and make it more sensitive. I don't like it too shaky.

[@MrLetsfifa12]

Crazy rig! I really want to make one myself but don't know where to start, from picking the best motors price and quality wise to getting the hardware to interact with the software correctly... I saw that you commented 2 years ago under a previous video of yours that you will be releasing a DIY kit, did you end up making it in the end?

[@mikeyearly]

I released the FS2 2 DOF sim which is available at mantis-simulators.co.uk this 3 DOF will be the FS3 and will be available later this year

[@nickst2797]

I always had the question, how does the hardware interact with game events? Does each game sends instructions about what goes on the the game scene (such as multiaxis acceleration data), so that the hardware can parse them?

[@mikeyearly]

Correct, all taken care of by Simtools

[@nickst2797]

@@mikeyearly Thanks! Simtools is the software? And it has a list of racing games that it supports?

[@mikeyearly]

Sure does, check out the website simtools.us

[@nickst2797]

@@mikeyearly Thank you very much!

[@live4wap]

Almost every simracing game provides a thing called telemetry. That's a long ass list of parameters like car position on the map in x,y,z, roll, pitch, speed, throttle, brake, handbrake, wheel position, etc. These metrics are getting captured once in a short period of time (like 1-5ms or less) and sent to a customer software like "Simtools". You can even write your own by enabling that option and reading the incoming telemetry as a UDP packets

game?
