Brilliant find there Frusheen! (And of course FSF_Ian!) (Kudos on the killer PC too.) Also the new Export.lua that vJaBoG32 posted is perfect as it shows the matrix code for resultant vectors with applied rotation and scalars. Much test flying ahead.

Does the dot show up on your desktop screen as well?

Great work MetalGear! I've ordered some Teensy's and looking forward to trying out your code as well. I've got the motor hardware breadboarded ready for testing.

Matrix33() function errors when put into export.lua. (Not implimented yet or I've used incorrect syntax?). I get a dsc.log entry of; 00256.044 ERROR Lua::Config: Call error LuaExportAfterNextFrame:[string "C:\Users\Dave\Saved Games\DCS\Scripts\Export.lua"]:75: attempt to call global 'Matrix33' (a nil value) stack traceback: [C]: in function 'Matrix33' [string "C:\Users\Dave\Saved Games\DCS\Scripts\Export.lua"]:75: in function <[string "C:\Users\Dave\Saved Games\DCS\Scripts\Export.lua"]:45>. The function LoGetSelfData() data.Heading, data.Pitch, data.Bank returns the same values as the LoGetADIPitchBankYaw() function.

WOW! Top notch work there Matbog. Keep the updates coming.

Grats on an absolutely brilliant build TR. I am sure you have found that there is never enough time now. You do however have me intrigued. Would you be kind enough to post a video of you doing vertical loops please. I would be most interested to see how your rig handles the 180° loop flip from DCS World. The software I use does not handle this inversion properly at all. I would be very very interested to see how your software behaves. Thanks.

Thanks for the heads-up! Looks like I will be skinning some zeroes as well :) (Many thanks Markindels for making this possible.) Thanks VH-Rock! Lots of pixel pushing, load and re-loads. But worth it. .

Wow! Excellent work. Keep it coming.

G'day, 7th October, 2018. Finally completed the textures for this Squadron. A fictional Europe scheme is next. RAAF 457 Squadron Pack Part 1 RAAF 457 Squadron Pack Part 2 Cheers, Brass. .

My understanding of why there are no new FFB sticks being manufactured is in the patent for "Force Feedback". A company that once made a rumble motor, patented it as "Force Feedback" and proceeded to make it's revenue from litigating against other "Force Feedback" manufacturers. (Including M$.) https://www.techdirt.com/articles/20080527/1619231238.shtml

IMPORTANT MESSAGE: I apologise for the loss of the images linked. Without warning Photobucket are now asking for $399.00 USD to restore the picture links. Please bear with me while I make other arrangements to host the pictures. G'day, The current spitfire textures are outstanding. Attention to detail is absolutely amazing. So how could they stuff up the upper wing roundel??? It literally only took 2mins to clone in the needed pixels. IMHO I reckon they are just chucking a rock. No matter. Here is a temporary fix until the template comes out. (Just a few skins lined up.) Note that the scratches have been brightened slightly by the NVidia DDS export utility from Photoshop so they are a little more apparent.

+1! It hurts my eyes everytime I see it.

Lots of good F-18 stuff at Hornetpits.org, the site name says it all...

Excellent post towsim. That is the crux of the problem. For the matrices to work you would need a full quadrature of pitch. Which we don't have access to just yet. The logic to extrapolate this would be a series of if-then tests. Then work out the angle quadrature. The graph below shows a near vertical loop which shows the problem with the radical change in yaw and bank. While we have ±180° for yaw and bank, we only have ±90° for pitch at the moment as per the ADI output.

Absolutely Agreed! The forces need to be relative to the pilot in the seat! If he is pulling 5g pitch up with a -5 bank angle roll left he is NOT going to magically flip over to +5° bank angle just because he happens to pitch over at the 90° pitch up attitude. Which is what is happening now with the only available values we can access in export.lua. This is a major flaw with DCS at the moment as it stands for anyone wanting more than just VR realism.

I am sure if you browse the links you will get an idea of what is involved. The basic circuit is about the same minus the opto's and disable switches. (Depending on the configuration these do come in handy). The motors are a typical car/truck wiper motor. A brushed 12/24VDC motor with a reduction worm gear assembly. The worm gear provides the necessary holding force to a seat even with the motor not energised. They are not stepper motors as such but are driven by a Pulse Width Modulation voltage to adjust the speed and polatiry to the motor.

:thumbup: CNC = cheap, fast, or accurate.

The intrinsic problem with DCS is that there is a roll and yaw inversion from export data whenever a near, to true loop, is performed, which is a problem for some seat movers who's seat frame of reference does not change during the inversion. It is not a problem with Simtools, it works well, it just drives to what it is given. @mrsparks Can I ask where you are getting your DCS pitch, bank and yaw values from please? @Frusheen Sorry for not getting back to you. I had a total Hard Disk Drive failure with corrupted backups. Thought I had lost the entire lot for a few days there!. Back on the job now.

Forget stepper motors for FFB applications. They depend on cogging which is not what you want where you want smooth input command feel for a joystick interface. They have low torque, and because of that loose command steps if stalled. DC brushed motors cog as well. This is not what you want for a joystick interface where you want smooth input command feel. But this will do for basic principle testing. Toothed belts are not good as they can cog as well. V belts slip under torque. Good quality gears is best. (Even MSFFB2 cogs!)

They might show up here every so often... I am sure this is on your list. http://www.flighthelmet.com/mm5/merchant.mvc?Screen=CTGY&Store_Code=FHL&Category_Code=EJSP Good Hunting! (Great facebook page btw.)

I like where this is going. (And excellent post Drakoz!) For best results use "zero cogging" DC motors. A reasonable gear ratio is needed to counter joystick lever forces (human input) while not drawing excessive stall currents on the motor and driver circuit. And as you've noted MetalGear_Honk and Drakoz, a good PID is essential for an Arduino to control the motors. I've got the hardware sorted but not the software driver.

Excellent Idea MacThai_75. I've found Simtools tp be an excellent simulator interfacing program that is pretty straight forward to use. If you have an Arduino, a motor controller board and motor, I've found the SMC3 program by rufusdufus is definitely the way to go. VR gets your eyes into the pit. With simtools you get your body into the pit!

YOU WIN! :thumbup:

Absolutely magnificent work! Can't wait to see it painted up.

A very exceptional build there X93355! If your not sure don't rush it until your convinced you have the right colour. From painting my SJU-17 MB seat with Gloss Black, Satin Black and Matt Black, from my experience Satin wins hands down. Gloss Black is Black. Most reference photo's I've seen in cockpit don't have a high gloss finish and alway appear an off black, very dark charcoal. Gloss is also very unforgiving in highlighting the slightest surface imperfection. Flat Black is close as it appears as the very dark gray required, but maybe a little too light. It holds any and every mark, scratch and greasy fingerprint. Satin works best. It matches most in-cockpit photos as it has the slightest sheen. Doesn't mark up half as bad as the Flat and cleans well. It looks good in daylight and photographs well. You won't be seeing the seat in night missions anyways so colour won't matter then. I don't have access to a full size spray gun so I am relying on paint out of a spray can. If I did have access to full size spray gun I would go Satin and lighten up the Black just the minutest amount. (Not to the Flat Black tone.) Just my point of view. Good Luck with your choice and I look forward to seeing the finished masterpiece. You can see panels painted Satin black in Part three here.
