Hi Al,
I've been working with a couple of guys in Norway on this(I'm in US). We use the "shared file" in Falcon4 to
get the G data. One of the other guys wrote a small program that runs in the background with Falcon. The
program takes the G data and drives a servo. The servo pushes down on the diaphragm of a pressure regulator
that controls the pressure to the suit.
The max pressure in high G maneuvers(real jet) is about 10 psi. The military uses this in simulators at about
5 psi max. I use mine at 4 psi max as 5 psi is starting to hurt.
I use mine more as a motion cue device than a simulation of the G-suit function. I've added a component to
increase the speed and sensitivity of the exhaust part of the regulator. By having immediate response,
changes in G feel like real motion(inertial forces).
I locate my compressor 50' away in another room. The rig makes a fair amount of hissing a farting; I wrap a
towel around it and reduce most of the noise.
There's info here:

Subject: [simpits-tech] Gsuit-Aircompressor-F4
I think someone has already been using a air compressor controlled by a computer to inflat a Gsuit for their
flight simulator?
My Gsuit is coming in on Wednesday (Thanks to Sukit from Thailand) and I was wondering how the setup is.
What kind of computer, software and compressor are used and if it can be used in conjunction with falcon 4?
My other concerns are the noise factor from the compressor...as well as the pain factor :)
Thanks in advance,
Al
