Vibrators

WOOHOO! Ooops, wrong kind ;-) (for a home made SimRacing cockpit) What I'm after is something that will take an electrical current and convert that to a mechanical vibration. I.E. An Engine sound from a sound card. I originally was thinking of placing a big woofer behind the seat of the cockpit but I don't think I can get a good enough vibration out of it to shake the seat and cockpit. So, has anyone heard of such a device that wont produce sound but will vibrate like hell. I'll also be hooking up a big woofer for the sound effect though. -- Michael A.

A "Base Tube" will do it also and it works off the sound so it matches what is going on... "Michael Barlow" <[email hidden]> wrote in message news:ITiz8.255950$[email hidden]...

OK, Did a search on "Base Tube" and found lots on vacuum tubes.

Get a sub-woofer, and crank her up. It WILL shake, belive me (try attaching it to the bodywork.) Is it just a rumble (like at a race start in GPL) or full tilting?

When they invented "rumblevision," the effect used on the original theatrical release of Earthquake in which the audience literally felt the earth move, the only technology they used was a very powerful speaker under the chair. In the 1970s, sub-woofers hadn't really been invented. I should think that a sub would do the trick, but it will probably depend entirely where you put it.

Michael... We have been working on this technology for almost two years now. I have tried just about everything....and I can tell you there is a lot more to this than meets the eye. Here's some of what we know: 1. Subwoofers don't work. The subwoofer channel is too low for the bulk of the engine sound frequencies that create vibration. In addition, the subwoofer is insulated...from the surface and is made to NOT vibrate...since the speaker cone is large and moves a lot of air. Engine vibration of the type that matches RPM revs is mid to high frequency. 2. All current commercially available "vibration" game devices are "toys"...they don't work...or they don't work well enough for sim racing, at least. Don't waste your money on them. 3. What does work.....at least this is the best that we have come up with and it picks up about 90% of the realistic vibration from the engines....is an amplifier and actuator system. They are expensive. Here is a picture of one of our simulators from last year with this system working. Note the two "actuators" bolted to the back of the Kirkey racing seat. www.pabst-racing.com/webscreens/tpracerig.jpg The cost of the system you see in this picture is about $1,000...for two actuators and the 300 watt amp to run them. These are very similar to the actuators used at Lucas Arts....for the vibrating movie seats they pioneered a few years back. Add in $300 for the seat...which is required (aluminum racing seats work...nothing else we tried did). The two actuators are driven by a separate 300 watt subwoofer amplifier. Even with this system, it did not work as well as we liked. Without going through all the things we tried that didn't work......here's what did (at least it gave us the 90% vibration I mention above): We run the "center rear" channel of a Dolby 6.1 surround system to the input of the actuator amplifier....set the frequency response "cross-over" on the amp at 180Hz...run the amp at full volume.....and because of this, you have to air cool the amp with a fan, or it will overheat and the protection circuit will cut it off after about 5 minutes of running. I have had several real-world drivers in the rig pictured.....they all agree its darn close....reproducing the engine vibration felt through the seat in a real racecar. I think this is the info you are looking for....but I doubt its much help, unless you want to spend a "grand" on vibration equipment. We are continuing our search for something that works as well.....at half the price. It won't be done for less than that....probably ever.

I use an Aura Bass Shaker. They're a transducer that was introduced a few years back for kids to bolt under their car seats to amplify ( vibrate) the floorboards, seat, whatever. They're rated at 25w and though that seems like very little power, they'll shake the eyeballs out of your head. They do make a minimal amount of noise but not enough to be any kind of annoyance. They originally sold for over a couple hundred bucks each BUT I found a few at Parts-express.com for about 40 dollars a pair. Aura doesn't make em anymore but they're out there.

Hey, those 'actuators'on the seat look exactly like my Aura Bass Shakers. Who is RBH? Any professional power amp could run wide open without overheating unless the actuator ( I beleive they're actually called trransducers) is rated far below the nominal wattage and you're overdriving them. In which case they will get hot as a pistol and may cause the protection circuits in the amp to trigger, as you report or the seat to get awful warm, as mine does when I pump 100 watts through mine. Got a url for RBH? Gavel

I have to disagree with you Tom, The transducers you are using have a very limited and low frequency response. Most subwoofers have a much better frequency responce than a transducer. Why use a crossover, with or without a crossover the transducers aren't going to respond to anything higher than 180 anyways. All power amps should be run wide open, then adjusted by how much pre amp signal sent to it. If it overheats you are doing something wrong. I use two 8 inch 300 watt JBL speakers and no crossover being pushed by a single 250 watt Audio Centron poweramp. One behind the seat and one underneath my feet. These speakers have a response of 20 to 4k, about 4 times the range of a transducer. You feel vibrations from all the sounds not just 180 and below. A transducer is just the driver of a speaker without the cone and basket, thats all. Save your money. "Gavel" <[email hidden]> wrote in message news:<[email hidden]>...

Mark, I'm Gavel, not Tom. <VBG> But I agree with you about the crossover and the power amp. You should be able to run the power amp wide open. But I think he may be using a consumer power amp ( receiver). My Aura Bass Shakers are rated at 25w nominal and if I push 100w through em they get hot and the circuitry in the powered mixer I've been using shuts down for a bit. So I've got a car power amp and a 12v converter I've yet to hook up..( to make it portable for lans). The original poster was looking for a a minimal sound solution and the transducers pretty much will satisfy that. Headphones can carry the rest. I have hooked up my whole P.A. to my computer once. 2 15 inch subs in some old Peavey folded horn cabs, PAS mains and two 1500 watt Mackie power amps. Wife complained that stuff was falling off the wall in the next room. <g> I once locked the dog in the room with a loop of the Andy Griffith song playing over and over because the little bastage peed on my shoes.

Actually the incredibly low frequency response of most transducers is preferred for home theater. You don't want your couch vibrating from every noise in the movie, just things like explosions. People said that if they felt vibrations from people talking it got annoying after a while, so the low frequency response solves that problem. Of course with sim racing I want all the screaming highs of the motor shaking my chair and pedals so something with a much larger frequency response is needed.

I was thinking that it will do the trick, But I also can imagine I'll have to crank the volume up too much. I did take my surround sound system with a good (un-powered) subwoofer and put that behind the seat and it did the job but I had to bring the volume up a bit more then I wanted to. I'm thinking of bringing this new cockpit to LAN events, so I'll need something like what was mentioned here earlier (http://www.vrealities.com/bass.html). As Stated, $225.00 is a bit pricy.

Just got done reading all the other idea's in this thread. WOW, lots of good stuff out there! I'll be putting a lot of gizmo's in the cockpit but this is the biggy that needs to be figured out. BTW: If I didn't mention this before, The cockpit (hopefully) will be going to LAN events. Odds are that if everything gets in the cockpit that I want in it, When I do go to a LAN event, I'll probably need a portable nuclear power station to run the thing ;-) -- Michael A.

Just wondering, where in the world do you find LANs where anyone actually wants to play racing games???

In the same vein, on a lark I picked up a couple of Aura Interactor backpack type devices at a show. I cut off the straps, bungee corded the thing under my chair (recliner) against the metal wires that run under there, and ran UT. It shook me so hard that my vision blurred. I have to run it on volume 3. It gives a great effect over rumble strips, and I'd venture to say that another in the back would work well. You may be able to find these fairly cheaply (I bought mine for $5 each).

I saw a website for a company that made just that thing, a chair or cushions for a chair that mechanically vibrate rather than using sound. Don't recall where it was, but probably a link on one of the expensive commercial game cockpit sites.

Gavel.... RBH no longer makes those units, or the amp they originally sold for them. I have not found a replacement as of yet. The transducers you speak of do not work very well. At least, I've not been able to make the ones I tried out.... work very well (I'm not an audiophile). They respond to frequencies that are too low for engine sounds....so the "frequency" of the vibration you feel is not "tight" enough to match what a V8 engine vibration feels like. Its hard to describe in words, but maybe you know what I mean? I agree with you...I was surprised the amp sold with the RBH actuators (their term, not mine) was overheating and kicking in the protection circuits. It only does it when the cross over is turned off...the amp set a max power/volume (300 watts, @150 per channel) and I'm feeding it the center-rear feed from a Dolby 6.1...with the surround sound amp "cranked." That combo produces a 95% accurate engine vibration. I used to turn it down....live with something "less".....but I tried removing the amp cover, attaching a 120mm case fan (running off the computer power supply)....and now the thing runs for ever without kicking out from the protection circuitry. Maybe someday the whole thing will blow up? .....lol.... I wonder if the transducers you talk about would work better if they were sent a noise signal from the center rear? Can you increase somehow, the frequency they respond to? I wonder? The only units I've found that claim to do what these RBH units do......were $1,500....and since mine work (for now), I wasn't inclined to experiment with them. I will try to find the link for them.....so you can at least take a look at the details/specs....see what you think about them. If I find it, I'll post it here. The "rig" that I posted a picture of (which no longer exists...I now have an enclosed cockpit with a roof) also uses a PA speaker system (18" Fender L/R mains and an 18" Peavey center). I use 6" commercial outdoor speakers for the rears...mounted within a couple inches of my head - L/R. If I crank this system....I get 120-130 db's in the cockpit (I use ear plugs...but that's perfect for recreating the sound environment of the real cars I've driven) along with a racing helmet with headphones built into the helmet.....that is separately amp'd and eq'd......to filter out all sound but the high's.....it works perfect to semi-isolate the spotter's radio calls...and it sounds like the "Racing Radio" system I used in my GT3 racecar). But, running this system "cranked"....vibrates stuff off the shelves and tilts all the pictures in the entire house. It also manages to get the cops out to my house quite regularly....and I live on 5 acres out in the country! .....lol... Fortunately, the cops like racing so I let them drive for a while (turned down)...they bury an incident report.....tell my neighbors that "he's legal.....but we did get him to turn it down"....its way too funny! Neither one of my neighbors who call the cops....have caught on to this yet. -:) Sounds like we have very similar sound systems.....like it loud and real! That's cool.

Sounds like the transducers are being overloaded; strange if that's the amp shipping with the units. Split em and just do a stereo or mono feed to them and see if it makes a difference. The things are only reproducing the bottom anyhow. I've never been inside of a race car so I haven't a clue how it's supposed to sound. But the shakers lend themselves to the suspension of disbelief for me. There was a fella a few years back who built a chair using pneumatic actuators and microswitches to tilt his seat forward and back with accel and braking inputs. Interesting idea . Vibration is okay but seat movement in concert with the sim would top the cake. I remember as a kid going to Disneyland and sitting in this mini-theater where they pretended you were going on a ride into outer space. On liftoff the seats lowered a little bit to simulate the G force. It doesn't take a lot of movement to fool the body into thinking it's feeling something powerful. And this technology was there in the sixties when I visited the place. So I'm waiting for the FF wheel companies to install a pass thru like a midi thru) that will allow us to plug in a chair loaded with small actuators or bladders that respond to the same output the wheel receives. Then, pressure sensitive switches to mount to our gas and brake pedals that will trigger a five point harness tightening or a seat lowering to simulate a g-force; nothing requiring massive movement, and finally a sound system to rock your socks off. I own a bunch of p.a. gear as I played in bands for years. I really don't use it to race but I crank it up every now and then.

I've gotta put my vote for the Aura shaker units - comes with 20W amp & plugpack,cables complete $25AUS I got the original seat cushion type. Great for those GPL haybale hits. Seems only the strap-on (there we go again) type is available now here in Australia from www.jaycar.com.au. -- Peter H GPL sucks ... you in "Michael Barlow" <[email hidden]> wrote in message news:ITiz8.255950$[email hidden]... > WOOHOO!

The transducers in these backpacks appear to be exactly the same as what RBH and Aura were selling in the entry-level Bass Shakers. I guess if you want to get anal and spend lots of money, you can, but these little buggers are great, especially for games. For movies you need a crossover circuit to cut out low voices and music, and leave only the really low stuff like explosions, etc. If you take them out of the backpack, and mount them directly to whatever you are sitting in, they work even better. They start to roll off above 160hz or so. I'm not sure where they start to go away on the lower end, but it seems pretty low. The amp that comes with them is sufficient power, and has several settings which you can experiment with to get the desired effects. I have four mounted in my sofa. A friend of mine is building a cockpit and has eight of them mounted to a seat from an old RX-7. For $5 a piece, you really can't beat it, even if you try it and dont like it. Clark Synthesis makes much more professional quality units starting at $300 or so. These handle a lot more watts, can handle a full range of frequencies, and are MUCH MUCH more powerful. And probably overkill for what you want to do. Get a couple of Aura Interactors if you can find them, you wont be sorry.

hey guys not sure youll get this post b4 thread runs out but i found the REAL thing for vibration goto www.thebuttshaker.com and check them out the EACH will rumble the he** out of a whole floor i installed one on my simulator and it is great i alos kept the sub for audio the mix is incredible as i can turn the shaker way up without blowing the sub speaker away my simulator is at www.moonliteserenade.com let me know what you think if you get this message.... contact me thru my website. ps::: some of my sim stuff is for sale (monitors,controllers etc)

Doesn't anyone remember the days of N3? It supprted a tactile feedback seat from VRF...Here's the excerpt form the N3 readme file. FORCE FEEDBACK VARIABLES Users with force feedback devices can tune the forces by adding the following two variables to their N3.INI: FORCE_SCALE_PERCENT n FORCE_DAMPING_PERCENT n Both can be set to the range of 0-200 and will scale the existing parameters accordingly. Force Scale is used to determine how strong a force is, and can be used to try to adjust the amount of force the game provides. Force Damping is a factor in determining how much resistance the wheel provides to turning. It would primarily be used to decrease the tendency of a wheel to oscillate under certain conditions. NASCAR� Racing 3 offers special support for VRF's tactile feedback seat in its intelliVIBE mode. The following parameters affect the settings and performance of the device. The following line must be included in the N3.INI file to activate the intelliVIBE support: VIBE_ON This next parameter is optional and can be used to scale the amount of vibration generated by the speed of the car. The number can be set to anything between 0 and 200, with 100 being the default setting. VIBE_MPH_SCALE n This next parameter again is optional and can be used to scale the amount of vibration generated by the engine rpm of the car. The number can be set to anything between 0 and 200, with 100 being the default setting. VIBE_RPM_SCALE n By default a parallel port address of 378 will be used. That is the address which almost all parallel ports use. To check your parallel port address, look at the Properties of your LPT1 port in the Device Manager tab of the System control panel. The parallel port base address is the left number of the Setting column of the Resource table for Input/Output Address. Consult the following chart to determine which number to use for your parallel port configuration if it differs from the default: Port Address: Use this number for 'n': 278 1 2bc 2 378 3 3bc 4 VIBE_PORT_ADDRESS_NUM n For more info please see www.tactilefeedback.com. -- Biz "Don't touch that please, your primitive intellect wouldn't understand alloys and compositions and,......things with molecular structures,....and the....." - Ash jimbo <[email hidden]> wrote in message news:EPVJ8.407$[email hidden]... > hey guys > not sure youll get this post b4 thread runs out but i found the REAL thing > for vibration > goto www.thebuttshaker.com and check them out > the EACH will rumble the he** out of a whole floor > i installed one on my simulator and it is great > i alos kept the sub for audio > the mix is incredible as i can turn the shaker way up without blowing the > sub speaker away > my simulator is at www.moonliteserenade.com > let me know what you think if you get this message.... > contact me thru my website. > > ps::: some of my sim stuff is for sale (monitors,controllers etc) > >
