I can recommend this DIY body-shaker kit.
Using this shaker -

And this amp -

You'll need a spare sound card output and a few leads. Also a way to attach the shaker to the underside of what you sit on which is an office chair in my case. Attach it with some spacers to provide a bit of a gap between the chair and the face of the shaker.
I was using it on one channel only but to get around this you could either use 2 shakers or, like I've just done, merge the 2 stereo feeds into one with a few resistors - http://www.rane.com/note109.html (http://www.rane.com/note109.html) Figure 2 for your average sound card output.
Feels really good with the bike ticking over and going over kerbs etc. Will also work with any other game or music, BF4 is amazing ;)
EdTracker Pro wireless is a better option I think and noy so bulky
Will be intresting to see a video of this setup

I don't think the EdTracker and this shaker are alike DD? Also can't really make a video of a feeling ;) Maybe I can take some pics of it mounted to my chair to show you.
This is a But kicker DD :P
And a cheap one at that! :o
May just give it a go myself :)
What guage wire are you using Teeds?

Just some old but fairly chunky speaker wire, about 18-16awg I think.
This was my version - similar concept but a bit OTT ;D

Was there supposed to be a pic with this?

Nice, I missed that.
Very nice H!
I've ordered the stuff needed just to give it a go. Ill give an update when i've got it working :)
Right, so i've got it set up (I think :P)
Do you have the amp on a soundcard output? I've got mine set up on the motherboard output as thats all i've got.
Yea mine is on 1 of the surround outputs on my mobo and I selected the output as headphones to feed the amp.
Ideally you should configure the channel to be 'subwoofer' channel either from the soundcard OP or amp.
The seismic shaker is designed to work at very low frequency and pushing a lot of high frequency into it is just a waste of amplifier power that could be focussed into the low end and causes the driver to run hotter. This is also why you need a beefy power amp as you require plenty of power available to 'fill' a low frequency waveform (power=area under the curve)
Lots of simple circuits on the web to make a sub output from normal L and R stereo, its just a summing amp and low pass filter, or at least set the power amp to cut the mids and treble and 'pump up the bass' :)
This is OK for those who do not like soldering stuff, just run it from a 12volt DC wall-wart supply;

When I set my output to sub-woofer the shaker constantly made some strange noises, no idea why? Impedance issues maybe. But as headphones it seems fine.
Also found that the vibes faded out as a bike revved up and i'd like to feel them throughout, so I whacked up the treble. I can now hear sound from the shaker but I can just about feel the bike at higher revs, think the cushion on my chair is soaking this up a bit unfortunately. Maybe another shaker attached to my handle bars might work, hmmm...
Problem you have is limited audio 'stage' in the game, the only bits that ''rumble' are the kerbs, the weird LF is possibly the wind noise or a noisy output from the amp. Your seismic shakers will not like driving higher frequencies for long and might get a bit warm.
This is why I started to use the telemetry accelerations to drive the shakers in a more realistic way.
I did start a shaker circuit (eccentric motor) that ran off the rpm signal for engine vibes:)
When I got this constant hum/buzz/noise when selecting a sub-woofer output, it was while not in game and also while no noises were being generated by windows? Not checked for heat but nothing has stopped working yet, fingers crossed.

Would be good but I imagine starts getting a bit more complicated.
Maybe one day sound cards will get a dedicated shaker output usable by applications.
SimVibe is the only API driven system I know of... but pricey
Variable simulated wind would be another great addition to the immersion level. Just a standard fan in front of you works to some degree, as i found out on a hot day in summer 8)
