newbie with some questions..

Hi,

I'm new here on this forum .
so let me introduce myself:
I'm Arjan Swets.... 40 years old (pfff) married with Karin, one Daughter.
I work as PLC programmer.
Hobbys: Robotics,electronics,programming,cnc

more about me on my homepage: http://www.arjan-swets.com

first my english is not very good, but i do my best...

I bought on a Flea market a secondhand logitech wingman formula force GP , but without the adaptor...
so i search internet, and i found it... and everthing works alright.

but i also found this forum....

and after reading for 4 evenings I have some questions about DIY motion simulation..
because I think to build something....

First what is the best system for car simulation? 2 DOF or 3 DOF? ( i know there is 6 dof too but i want to start not to difficult)

and then 2 dof like this:


(i have also see something like above, but with a 3 axle . see http://www.jimspage.co.nz/pictures.htm
, is it than 3 dof?, and is this better?)

or 2 dof like this:



or 3 dof like this:


or 3 dof like this:


I think the last one... ?

and now more questions....

what do I need for software?
works it with all simulation games? or games with DirectX.
what cost the software?

What do i need for electronics?

eeehh here on the forum i see some ,where the monitor moving with the simulator, and some where is the monitor standing still in front of the simulator....
i think it is better (?) when the monitor is moving with the simulator?


i stop now, maybe i have more questions later....

nobody? hmm

Hi Arjan,

Welcome, sorry that nobody replied back until now. We are busy building our simulators... 8)

For car simulation its better to use 2DOF that is more simple to build.

You can build something simple like this:
tronic-s-full-motion-car-racing-simulator-using-x-sim-t471.html

And my site with full instructions:
http://ptyxiouxos.net/greekbotics/user_ ... ulator.htm

OR build a SimforceGT type simulator:
ego-s-simforcegt-with-dc-actuators-t547.html

For electronics you can use those I mention on the above site, or build the new better ones that I describe here (DIY):
tronic-s-amc-motor-motion-controller-with-pwm-servo-output-t559.html
tronic-s-diy-dual-mosfet-h-bridge-t820.html

For software you should use x-sim software located here:
installer-x-sim-beta-1-6-9-t787.html
The x-sim software is free!

As you can see its all here, just a little search is needed! :thbup:


Best Regards, Thanos

alright... but which one is beter?

This one:
tronic-s-full-motion-car-racing-simulator-using-x-sim-t471.html

OR the SimforceGT type simulator:
ego-s-simforcegt-with-dc-actuators-t547.html

the last one is more simpel... and maybe faster (?) but a short movement?

and is it beter that the screen is moving with the simulator?

Hi Arjan,

Its your choice!

Some prefer the SimforceGT type as its more simple. But it can be used only with car simulation games! Its advantages is that it can be used with projector screen as the screen in front of the driver stands still. And the footprint of the construction is a lot smaller, actually two DC motor actuator behind the seat!

On the other hand the joyrider type can be also easily converted and used as Flight simulator! :fly: When I originally made this motorized joyrider sim I was using it only for flight simulation until I tried the x-sim software and realized the possibilities with car simulation! And the immersion, in my opinion, is much better since everything are following the cockpits motion (screen, steering wheel, pedals). BTW, I used simple car windscreen wiper motors to move it... Did you seen the videos?

Regards, Thanos

I would be interested to know how the motorised joyrider compares to something like Force Dynamics 301. Since it has that extra dimension of movement.

No simulator that I know can compare with FD301 (or the more new FD401!!). Its a professional commercial simulator that costs $$$$$ after all!

We are making just cheap home motion simulators here (yet).

Regards, Thanos

ehhh... Do the DIY simulators not move forwards if you press on the brake? ( for the g-forde feeling )?
thats why I thought it is beter that the screen is moving with the machine ...
because you see the horizon on the same place, so the movement feel as g-force....

The SimforceGt does smaller angle motion and it doesn't affected too much from the stationary screen... It mostly simulates the stress on the hand muscles (when holding the wheel) during acceleration... It tricks the mind using body stimulus that combined with synchronized optical stimulus gives you the desired immersion.

And its true that with the screen moving along the motion path the immersion its way better! And it gets even better if you fully enclose the cockpit to block all the external reference visual cues! I wish I had the courage to try enclose my joyrider cockpit too this way...

Regards, Thanos

this motor? is that a good one?

http://link.marktplaats.nl/156908944

No, its not good cause it will not hold itself the position under load and will be difficult for the motor controller to drive it (will remain under constant load!!)

See this thread for more info:
wiper-motors-whos-shaft-do-not-move-under-load-t916.html

Regards, Thanos

to bad, the where cheap...

so for 3 motors i need one tronic-s-amc-motor-motion-controller-with-pwm-servo-output-t559.html and two times tronic-s-diy-dual-mosfet-h-bridge-t820.html ?

nobody?

and the hexfile for the avr?... can i download it ...or buy it?

The hex (firmware) is free. Have a look at the corresponding thread. You will find all you need at the starting post.
As well this thread is the proper place to ask about the controller.

Regards
Christian

Can i also use this power mosfet for the H-brigde?

i have 24 volt motors/ 400 watt so that 16,66 amps....
