Hi, Christian,

Yes, I hope that this was the last "bug" ... I want to move on to the 6 DOF AVR ultimate motion controller and these kind of problems just keep me back, trying to find solutions...



Anyway, I have ready the 6DOF firmware for six simple RC servos in case Sirnoname interested to built a small prototype rig for testing his new Profiler2... The same firmware is now using John (planmix) for his 6DOF motion software for FSX!




The 6DOF RC servo firmware can be used with the last AVR motion controller v1.5 but with a smaller crystal of 22,1184 Mhz (22.118.400 hz). No mixing is done in it and every axis motion is independent from the others.

As I have said before the coderound cycle is 46Khz (checks the USO 46000 times per second) with period of 0.0217ms or else 21.7us, uses 115Kbps serial speed and the USO string that commands it could be:

AB~1~~2~~3~~4~~5~~6~

where the 1,2,3,4,5 and 6 numbers represent the six axis.

For the test that each axis was reading ok with the current Profiler 1.6.9 , I used this string: "AB~x~~y~~x~~y~~x~~y~"

EDIT: To connect the six servos I used the four servo ports of the AVR montion controller v1.5 for servos 1-4 and the ADC ports 7 & 8 for the 5-6 servos!

Hi,

As I had many requests that it was not easy find all the info I gave about my electronics, I decided to collect them all in a single zip file that is easy to download...

http://ptyxiouxos.net//greekbotics/user_projects/Flight_Simulator/AMC1_5_DSMhb1_2.zip

I hope that will help many people... Later I might compile a Html guide thru all these files to also use on my website.

Hi,

It will be not much time before we will see some motion sim cockpits fully working and interfaced with my AVR electronics!
I almost feel shy that I had not much time to put all the parts together and use them on my joyrider first. Any time I wanted to focus and finish it, something new was getting in the way...

One of them, that have all ready, is Erich, that he kindly send me some photos of his boards!

His motion sim is a 2DOF joyrider-like cockpit but with all-metal welded frame! I hope that we will have video from it in action soon! At least sooner from mine... :-)

Thanks Erich!

Hi,

After general request for PDF PCB layouts that are placed in single page, I made single pdf layouts for some of my boards:

Hi

I had the chance to test personally Egoexpress's AVR motion controller and DSMhb boards and here are some photos and video:

Enjoy

Hi Thanos,

your parcel arrived yesterday. I have been able to pick it up today. I'll try my best to set up the sim until tomorrow evening.

Thanks alot!

Es geht los....

Just an uptdate.

I had a little drawback. Today I noticed that the GND of the actuators pots have connection to the case. This causes some trouble. Now, I have to find a way to isolate the pots from the case.

Just wanted to tell you guys that it is nothing caused by Thanos' brilliant interface. Its just my acutators!

Christian

Hey..

Any news on the projekt, I am very interrested in hearing about it. Here are some picture of mine, its not finished but I hope to get the last parts monday or tursday.

I also bought 3 motors and some pots... ( only need some gears for the pots )

HEY!!! Is this a mirrored photo or you have etched WRONG your PCB boards??????????
