I remember the first time I saw this rig in a video I wanted to know who was running the TTB with the sickass swing set under it, and belive me Winter's name was all over it.
OK, to re-hyjack this thread:
Key Words:
Whamo Toy Wheel thingie
Star Bird (vintage electronic star ship toy)
Inclometer
Sampling rate
CFM
Varible Orfice Valve (VOV)
Venting and re-generation
As I got to the few last pages here I started putting some pieces together in my head for this project, whether you use them or not are to your own discresion.
The automated system your looking at has to self adjust, the human factor has to be removed, the joy stick idea is fine for preadjustments, and a manual over ride is a viable idea, but I belive in order for it to be a sucessfull system something quick has to be implimented.
For us vintage folks lets take the old Whamo toy, the little wheel on the wire, the one you tip down and up to make the wheel follow it down and around and back again.
Step that up to another vintage toy called the Star Bird which was a star ship that had electronic sounds, as you nosed it down ithe sound of the star ship slowed, as you tipped it up the engine sounds increased, and it was proportional.
As a youn curious lad I took the Star Bird apart and noticed it had a ball suspended on to wire rails similar to the Whammo Wheel, as you tipped the star ship down this signalled the electrinics in it to make decending noises, and the opisite for tipping it up.
Now think of an inclometer with a ball and to wire rails, the wire rails are much like a potentiometer, as the ball moves up or down the rails it creates a different resistance value, now you have two of these for "X" and "Y" axis.
The G-Tech, g-meter uses the same technology for mesuring horse power, torque, to make quarter mile times and estimated speed acurately to within +/- 10th of a second.
A PCM/ECU, or "Brain" as Winter calls it, is used for high rate sampling of these axis and for how much movement is actually happening, with the programming diagonal axis can also be calculated "Z", or even a "Z" axis can be intergrated into the system, so it would actually be a 3 channle system.
The PCM/ECU would then control a varible orfice valve (VOV) simliar to the ones used in certian A/C systems to control the flow of air to the strut, and/or venting (here is the speed of air control) now becuase this is an orfice, this will also create a drop in pressure and temature so this also has to be calculated into the equasion, baised on what the vehicle is doing, now in Winter's other calculations you can also incorperate a thermistor resistor to account for temp changes, note that pressure is directly related to tempature, be it at the storage device or/including the air strut it's self since the ammount of use will cause the air in the strut to heat up increasing pressure, allowing the PCM/ECU to vent unwanted pressures, or in the opposite, adding more due to low temps and pressures.
The PCM/ECU can have programming much like a CD player where is over samples the input several times a millisecond, and can make precise adjustments in the same time frame.
Now as a souce for compressed medium, going from memory, liquids can not be compressed, so Winter you'll have to fill me in on the liquid CO2, or nitrogen therory, as for using compressed air, you will obviously need a storage tank, just like you would for anything else, but a compressor that will also sustain the amount of air that will be used, and be able to keep up with the demand for regeneration, and the alotted amount of CFM it will take to sustain this, much like using an air tool, 90psi @ 9.2 CFM, because this sytem will be constantly be ajusting it's self, being it a small amount or large.
There can also be set programs for street use and off road pre-programmed, for ride quality, control, stability and so forth.
Ok, Ok sorry enough of my rambling, I'll stop.
Mr. BKennedy could you direct me to a thread with you front end set up including pictures from under the hood and about the TTB?
BTW, Fantastic work you two!!!
Jeff - going back to watching the thread
