3DOF power simulator

Hello guys,

Me and my friend the cure we are putting together a project that has been ongoing for many years, since before it came out xsim.

discover this site was a breath of fresh air for our minds, because we were stuck. :oops:

Now we managed to put together the forces due to electronic discovery right here.
We still have some "small" problem with the motor controller of the rotation because of electrical noise that brings us to the K8055 and sent in error. :evil:

begins with posting the video link of the beta test: http://youtu.be/Edsc_NUHLcQ

from here with the time, I will explain the entire procedure. If successful

sorry for bad english but it is easier to write fast with google :ugeek:

for the moment is everything .... a greeting Basthard

Thats impressive! Well done there!

X-Sim is registered since 2002, I hope you where not stuck so long

If I would you, I would as fast as possible throw away the pneumatic and K8055d! This stuff is designed for the first tryouts (and costs too much money for the result).
You will loose much fun and a big part of professional look if you continue with this type of engine.
If you both have problems with building the fitting electronics like the AMC board you can contact the staff for help.
It is very simple to add a chain drive to your current pneumatic setup and open all the air intakes to use the pneumatic lever with a electro engine.

The rest of the simulator looks great ... continue your work.

I had a look on the other video you have there without the music... Pneumatic actuators??

Surely you could use AMC1.6 to move your cockpit way more precise and faster response than K8055d.

Other than using pneumatic, great looking project!!!

Hi sirnoname,
We are excited to convert everything to electric with linear screwball actuator but we wanted to know first:
the AMC card can control 4 motors ? with what?
we would use, if possible, these H-bridges: MD03 - 24V 20A H Bridge Motor Drive or advice something else?
AMC card is difficult to program?
you manage to run it on 1 pc?
I am convinced that we will want the isolators for engines (now we have this http://bffsimulation.com/i2c-isolator.php)

Thanks and look forward to answer
Basthard

always sorry for "good" English :roll:

You don't need expensive Motor drivers like MD03 anymore. There are very cheap substitutes all around the internet *

So, for a 4DOF, you could use:

2x AMC1.6USB
2x High Current Dual Motor Driver

You can drive as many AMC1.6 you want from the same computer. I have a single computer (laptop) to drive two AMC1.6 while running the game on it.
I don't have a video of using two AMC1.6 at same time as I only have one at the moment, but here is a video with my other boards AMC644USB running four axis (its in greek): http://www.youtube.com/watch?v=G6S50KYwKEI

AMC1.6 is very easy to program. You connect four cables from the FT232RL USB module to its programming port and run a batch file that autodetects and programs the board.

BTW, these motor driver modules have their own isolation from the motors... read their description.

Dear Tronicgr,
first I had not thought about fit 2 cards!!
second:
you became my guru now!! :lol:

now I just find the time to put the pieces together ...
and I have to prepare the actuators...

i have a last 2 question "for now":

wich kind of encoders could i mount?
there is no way to install an E-stop, otherwise we will do the traditional emergency stop! :oops:

thanks

I'm not a guru, but thanks.

For linear actuators, depending on the amount of turns they perform to fully extend/retract, you may use a industrial grade 10k 10-turns or 25-turns potentiometer. Connected on the screw of the linear part more likely.

For DC motors, its very easy to attach some heavy duty limit switches with reversible action using large diodes.
