News Update Pneumatic G-Seat

at the moment all 4 servos are connected to Axis 6b.

I needed more axis to define in Simtools

I already use 5 Arduino uno in Simtool.

1 Arduino for wind simulation and vibe with SimHub.

Looks fantastic, thanks for sharing!

Ive been pondering doing this for years but ive been unsure of the speed. Now that got a system that moves my whole rig around i can drop the direct flaps and go for this i think. How is it for racing? Is it fast enough?

Ive actually bought 12x and plan to use 4-6 in the seat and perhaps do a Anti g suit style for flying with the rest. Its better to have them and be able to use it later

yes it works damn well!!

Finally got part of my order of 10x as i was just looking at the numbers on the pad but turns out they are 9x16 so they are a bit small. First impressions are quite good though!

Another thought is that you could probably fabricate these if you need specific sizes. Just a valve, pump glue and some tough inexpensive plastic. Then i would definitively go with a larger hose. 5mm and even less on the fittings means more torque needed and slower air flow. You could probably fit larger valves on these too though.

I have made 4x square from the wrong ones ive bought and ill glue them together instead for a larger surface as i wait for the rest.

Another thing is that flight and car is a bit different but since you can just move the pillows around you get get a better heave for flight and sway for racing.

how does the air bad add to the experience ?

These are just my initial impressions and i was expecting it so it wasn't a surprise. If there is equal hard pressure on both sacks and granted they are somewhat small you can feel small changes well and its not really a big issue. But the bigger bags you got the more of an issue it becomes going from 100 to 0 quickly

The bag i made is about 29x14cm and airflow is severely restricted if i put my full weight on it and it takes a while to empty

So small stuff, great! Bigger stuff and you need bigger tubing. I will modify mine with bigger valves for sure.

Would i still recommend it, no doubt! Its so easy to modify and implement!

I think ill be using it as a anti g suit to put pressure on top too. The big one works well over my belly.

@xxpelle : very nice harness tensionning system!

Please, I have some questions for you
How is connected the servo to the roller?

Are the roller cantilevered at the end of the servo? I'd be have been afraid that they bent...

xxpelle, great work, could you share the files for printing? Thx

Hi Torsten, Firstly congratulations on a fantastic yet simple kit to provide pneumatic G-Seat capability. I have downloaded and am in progress printing the 3D parts on my Ender3. (im also trying to source the additional parts).

Can I ask two things please:

1. Was everything included in your download zip for the servos/pneumatic bags as the picture you have here has some round clips and also a rectangular cutout which were not in the download, not sure if I need them?

2. Is your 'current' Arduino code the same as you uploaded in 2018 or has anything changed, i.e do I need a refresh of the code?

Happy to show off with credit to you with a few pictures and videos once all completed.

Kind regards,

James.

Sorry I would have tagged you @xxpelle in my post above but for some reason I cannot edit my post.. maybe because im new
