Flight simulator pedal project
« on: February 03, 2014, 12:44:58 AM »
I started a set of helicopter pedals with toe brakes. I was just testing the look before committing to welding. The toe brakes will be using 25lbs pressure sensors which is a different approach from anything I have seen before.

Looks like an interesting project Shawn. Are the pressure sensors piezoelectric?

You know what Tom, I don't really know. An internet friend of mine was developing the interface boards to use these cheap "thin film sensors" but what type they are I'm not sure. When I get home I will check the manufaturer and find the website again. I think this solution will not only be easier to setup but will add realism. Most pedals I have tried or seen rely on distance travelled not actual pressure applied to regulate the amount of braking applied in the sim. I need to research progressive pressure springs now, I don't even know if they exist but Google is awesome.

Here is a link to the sensors I have bought. My buddy has tested them on his IC board with great success so far.

Looks like they are QTC based.
It's one of the few bits of Quantum mechanics that has an application in real everyday life.

My flight sim buddies are going to be really impressed now when I tell them I incorporated some quantumn mechanic principles into my new garage built pedals ; )

Hi Shawn,

Looking good.

I saw over on hackaday, a link to this guy's flight sim Cockpit.I realize jis is kind of basic, but I didn't know there is a whole culture around it...

Hi Eric, it's actually amazing some of the cockpits folks are building in their basement. There are thousands of people and a number of websites dedicated to home cockpit building. I like the building part more than the flying but a trip around the patch with a beer or three is good fun.

I decided the pedals were going to be a dual setup so I got to work on building a dual flight stick to go with them.

Ready for welding, I had my wire feed set way to high and instead of stopping and figuring out what was wrong I welded most of both parts first. : ( I really need to do more welding : )

You will just have to imagine the axle running between these parts.

I need to bend some tube for the actual control sticks, the PVC tube I am using for the photos is way to flexible plus I don't think I can bend it properly. Any suggestions on bending aluminum tubing without the right tools?

Aluminum conduit? cut it too long, thread the ends with pipe threads, put a cap on one end, fill it with sand, cap other end, bend it to suit.. cut threaded ends off.

thinner tube you will have to turn a plug and dowel it in place.

Thanks Dawai, I was thinking about trying that trick with sand. I have never seen aluminum conduit but I haven't really looked before either. Aluminum extrusion is pretty expensive where I am but I guess if I don't try I won't know. Thanks for the suggestion

I couldn't find aluminum conduit so I am trying a simpler design with plain old EMT. I have removed the galvanized on my belt sander and will have a go at welding it.

Hi.

   well.. looks like you bent the emt allright.

   I built a buddy a "bush bow" from pvc, inserted plain old fiberglass "electric" fence posts into it. (solid 3/8" fiberglass rod)  One rod is about 35lbs, three makes me quiver to draw the bow (somewhere around 100).. SO.. if you do decide to play some more with the pvc?? it can be stiffened up. 

  You can also split a piece of 1/2" and slide it into a piece of 3/4" grey pvc. (use ky jelly)  Search on youtube, bush bow, pvc bow.

Little more progress made today. As soon as I get the neodymium magnets in the mail I'll start working on the electronics.  Pitch and roll position will both be read with Hall effect sensors.

I wish I could powder coat the shafts but my toaster oven ain't near big enough.

I got get back working on the pedals, that's what got me started on this whole project in the first place.

I got the roll damper installed today, hopefully I will have time to do the pitch tomorrow.

Quantum brakes !

Does that mean they can work or not work but you won't know until you press them ?

I had a Citroen BX that utilised that principle. Got rid of it as the uncertainty  scared me to death.

Or they can be both off and on at the same time ?
