@lancashire lad

I think those amps, some have mentioned, noticing delay when using their own internal soundcards. I know I have one sitting somewhere as well as the 100w variants.

If you find any delay, try using the Startech 7.1 card but connect to the amp with 3.5mm jack. That way all your effects mapping to channels in Simhub will be under 1 screen too instead of 2x amps operating/appearing as 2x soundcards.

Soooo, what IS the answer?
I dont have all the answers (shock) lol.
With the installation he has now the units are direct, maybe even too direct on the body as he leans into them.

Again not the same as a hard shell seat but Im sure hes enjoying it for what it is. May inspire others and will be better than HF8 or whatever it is seatpads.

Some isolation at the seat bottom might help but in that setup, its almost like having the units strapoed to your body...

Id be interested to know what Hz he uses most but think it will be quite narrow in the range used?

If hes happy, Im happy...

@Mr Latte Ive not noticed any delay as the amps are plugged directly into the laptop, using bluetooth yes there is a delay but I don't use that, next time I'm on I'll check the frequencys. I sometimes go months without going on GT7 or doing any racing. With PSVR2 the immersion is great on GT7 and the shakers add to that.
 
What you are trying to do, appears like talking yourself into getting effects being developed for the concept. With not having a suitable seat I do not see how you are going to be able to experience how the effects are being made to operate over various channels.

I appreciate your willingness to help but, Im not trying to expirment with how this approach can or cant work on folding chairs.
Completely understand.

What I am trying to do, however, has zero to do with effects being developed for the concept, and everything to do with adapting a foldable seat to recreate the intended experience of the “ideal” seat type.

You’re absolutely right - I don’t have a reference for the intended experience…so how about this - I’ll buy an office chair with a hard back (I found a used one I can pick up locally) and the rest of the hardware to appease your requirements, then I could offer feedback for effects (if/when you get back to it). At the same time, I would have a reference for the intended tactile experience, and could use it for side-by-side comparisons…thereby being able to adapt the Playseat Challenge for the effects, rather than the other way around. Then, if you are at all interested in my findings/experimenting, you are more than welcome to ask. Otherwise, I’m just another guy to help with testing your effects.

As evidenced above, I’m already 4 (not 2) transducers in. I’m typically a head-first kinda guy, so I’m sure the rest of the transducers will be along before I can afford them, lol.

Would that scenario be agreeable?

@Mr Latte Thanks for your offer to grant access to the old chat. I accept. 😊

Regarding my involvement in current and future developments, here’s a piece that you may be missing. I’ve noted that several people, in the past, and in this thread, just go and do their own thing with your effects, with whatever hardware, without regard to your passion and expertise in this particular field, nor have they, according to your recollection, expressed gratitude.

I’m sold on the concept/vision, and on your method for achieving the ultimate expression of RaceBass. I have no interest in changing your hardware recommendations, and I have ZERO interest in developing my own effects, nor for you to change the way you develop effects in the least. I have a family (wife and four kids), own a restaurant, and I simply don’t have the time for or interest in developing this from scratch, when there’s already somebody who is years and years ahead in the development of a system that is probably more detailed than I could conceive of or even have the drive to imagine. That’s your world. However, because I believe in what you’re trying to achieve, I see an opportunity to expand that functionality to a much larger audience, including myself, by adapting it to what I presume to be the best-selling sim-racing cockpit form factor…Just have a look back at how many people in this thread have been seeking this experience for their foldable/stowable racing seat.

For clarity’s sake, here’s what I’m proposing: You do what you do - develop those beautiful and amazing, layered multichannel effects that I’ve been reading about, but have yet to experience, for the hardware and seat type that you deem the most appropriate - the thing that you have been and would be doing, regardless of the existence of me or my aspirations. I’ll replicate the base requirements of that setup as a reference, offering (hopefully valuable) feedback; and on the side I’ll attempt to use that reference to develop a solution for my Playseat Challenge, which would simply seek to replicate the tactile experience for which RaceBass aims, all while requiring zero extracurricular input or involvement from you.

Hell, the fact that I’m being so transparent about my goals is, I should hope, an indication of my sincerity. I could’ve just said, “Okay, I’ll get an office chair.” I really don’t know how to express my ambitions or sincerity any more clearly, and my hope is that you will strongly consider allowing me to be involved with future development. If not, I’ll gracefully embrace defeat and accept the access to the old effects, and I’ll move along (a little drama right there at the end for the reader’s entertainment 😁). Thanks for your consideration.

PS Jeez, I don’t know if I’ve ever worked so hard to be a part of something. I feel like I’m pulling out all the stops in applying for a job that I desperately want, haha.

three, four knock at the door :)

Late here, let me consider, mmmmmm.
Will read over your DM, see whats on the menu.
I see 3 of your eggs are sunny side up, lol.

Try to get well acquainted with Simhub, watch videos, guides and see the offical page for info.

Send me images of this seat you mention, also take a look on overtake forums. I think a guy had a similar seat he modded (show your rig section). Recall he mentioned having issues with the previous exciters (needed care with volumes and Simhub tests) and he moved over to the more durable TT25. They have a protective shell.

Well, yee gotta gotta love a trier, shows you are indeed passionate...

Have some other people helping with effects and testing too, but closer to home and more PC focused. I dont want too many or need to go as if I am chasing after folk, wears me down.

I must be over 4000 hours regards tactile experimentation with Simhub within the last few years. So hoping by this year I start to get the hang of it. Can tell you that I still come across, some methods I have not seen any other approach do with effects and then I think, gees why did I not do that earlier. Maybe thats an age thing, starting to creep in....

Oh yeah, issues were not so much about gratitude etc, what ruffled me more was that many of the people would not have discussions even among themselves.

@Mr Latte @q445187 Couple o’ local candidates. Definitely looking to not spend very much here (these things cost hundreds of dollars, new), so I’m good with some wear; but I want to make sure I’m getting a suitable one to use as a reference, so let me know if either of these will serve the purpose. My intention would be to remove the wheels, and maybe find some suitable feet with which to replace them. I assume, based on the shape, that they both have a solid shell under the seat cover, but won’t know until I see them in person.

The big thing is that the back side of the seat must be hard, you have to attach 3m dual lock to the back to attach the exciters. Soft, pliable, or leather/vinyl won’t work.

Hmmm…I wonder if I could remove a section of the seat cover on the back where each exciter would mount, assuming there’s a hard shell underneath…

Also, I could screw-mount the mount/“cap” to the shell, through the cover, after drilling pilot holes, then attach the BDS units…

You need something that at least resembles a bucket seat like a hard shell.

This as cheap as I could find and even then it's not really a sim seat but might work.

Also are you aware of

Okay. Thanks for looking into it. I guess I thought you had a specific model or design in mind when you mentioned the “office chair” option. Looks like this project is going to be custom all the way around, lol.

Maybe, in the end, I’ll just design (with your blessing, of course) a no-compromises stowable rig, Latte-colored, custom-built specifically for RaceBass, and name it…wait for it…RaceBase, haha. I jest…

This oughta be a fun little (or not-so-little) project…😬

Startech 7.1 and Nobsound M5.1 ordered. It looks like the latter will take a couple of weeks to arrive. That’ll give me some time for prepping. That summit racing seat sure looks tempting…

My AliExpress came a little quicker than expected, I had it in my mind “slow boat from china “ lol! It never crossed my mind they had airplanes now!

The price was sure better!
 
In case anyone is interested, here are my first attempts at sketching a design for a backing structure for my Playseat Challenge. It’s not perfectly to scale, but I feel it’s a good start. Plus, it’s always just good to express an idea visually, to “see it in action“.

The aim is to develop this flexible “web” in such a way as to conform to the seat’s shape as formed by the user, providing a perpetual point of contact throughout the entire network, creating a tactile environment that will represent, as closely as possible, a 1:1 representation of the intended expression of the full RaceBass experience, in a foldable and stowable form factor.

The initial material(s) of choice will be a combination of plastic tubing and fittings, in the form of 1/2” and 3/4” chlorinated polyvinyl chloride (CPVC) and cross-linked medium/high-density polyethlene (PEX). I believe these materials to be an optimal combination of flexibility and rigidity. As a bonus, they’re also similar in structure to the polyethlene that plastic racing seats are composed of. CPVC fittings can also be used with PEX, which should provide an easy solution for transitioning between sizes/material for the sake of more/less flexibility/rigidity. In my initial feel test, both CPVC and PEX seem to be very performative/responsive across a range of frequencies, ranging from 5 Hz up to around 700 Hz, beyond which the vibrational frequencies seem to become too rapid for any significant usability in a tactile environment. To boot, they are both relatively cheap! (Mr Latte, please feel free to comment on those numbers 😁)

As seen in the sketches, there will be two mounting points on each side of the Playseat’s frame (indicated by the blue marks), one mounting solution at the top of the seat, via three velcro straps, and one pair of supporting “legs” extending to the rear “foot” of the frame, at the floor (these “legs” will easily disconnect when folding the seat). There is also the potential for extending the tactile webbing to the underside of the seat for additional transducers, should that ever prove useful. All of this will work together to form a suspension system of sorts, that will accommodate the user when seated, maintaining the comfort of the Playseat while also providing a seamless point of contact for the transmission of those beautiful, multi-layered tactile frequencies. Various fittings can also be used to accommodate more severe topographical variations. The BDS units will be mounted directly to the “web”, as shown. I’m VERY interested in how much this design might be able to isolate the vibrations from the rest of the rig, through transferring energy directly to the body.

I would LOVE any feedback anyone has, or questions that might challenge my design and help me to refine it. Thanks for reading!

Had no idea…
My first one, decades ago I made out of a put together shoe shelf from Home Depot! After racing it was my end table 🤣

HAHA!! I wish! 😁

Nah…Having grand ideas is my SUPER POWER. The execution? Well, we’ll see how that goes. I have the materials, though!

Since I was a kid, I’ve always had an interest in engineering-type things. Somehow, I ended up in the restaurant business. Go figure. 🤷‍♂️
