Damn you JBaymore! you made me snap this time!! LOL! Grin

It's been great fun watching your progress thus far, and I have to say it all looks very well thought out, and you are a master with your hands (ooo-err!!).

So, with all this encouragement and great tips, I've decided I'm going to give it a go. I want to make some rudder pedals first, but I need to get some bits together. I've already dismantled the old vaccum cleaner for parts.... 8)

I have a digi-cam so I'll record my efforts with the workmate and the drill for your amusement!!  Grin

ill give one hint . . . . the eyes and the ears create motion . . . by merely blocking out surrounding references i.e. putting your 'sim' into a box or something, you will experience motion, i.e. tilting, flipping etc. etc.  Plywood casing i might say. . . . i just probably confused you.

Yup, I agree with that.

My problem at the moment is money and space. Money I can generate, space I cannot.

I figure in the end I want a "generic" 2/4 engined cockpit, enclosed, with all mod-cons. That will have to wait until I can get some more space. For now, I'm going to concentrate on my rudder pedals, as it's something I've wanted for ages, but never got around to.

Once I've made them, I'll draw up a set of plans so anyone who wants to can make their own.

Polynomial,

Yes... I certainly plan on this. 

Still trying to decide how much "realism" I want to expend on this enclosure issue.  I know that the base (footprint) of the sim will be rectangular.  What I am pondering is if the upper part will be constructed so that it tends to taper inward like a real cockpit.... or if it will just sort of be "boxy".  You could say that I'm deciding on how many polygons I'll use  Wink.

Another issue in this upper part design is the forward (and eventual side) display(s).  I may start with monitors........ and eventually want to go with a projector for the forward.  Trying to figure out how to design it so that it can start one way.....and then end up the other over time without having to do a major rebuild.

best,

...................john

Ric,

Hey..... welcome aboard the "homebrew" bus!  Now your "Sim headaches" have really begun.  And watch it there with trying to put the "hex" on me  Wink Wink.

I am going the "generic" route too.  Trying to go with a recreation of a specific plane is a sure way to spend BIG bucks, I think.  I also decided to model only the left side up to the center pedestal...... I don't HAVE a copilot anyway so why waste space and dollars?

The first thing I really wanted and then quickly "canned" was all backlit panels so that the control labels were lit.  Seemed easy at first..... then as I analyzed it....it got either REALLY complicated to make it look OK........ or incredibly expensive to solve that by buying premade panels.  I also relized that the few GoFlight units that I was planning on using (like the autopilot) are NOT backlit anyway...... so that would be an issue too.

The current total "footprint" for mine is set at 57" x 62".  Roughly 25 square feet.  Tight fit for all the stuff...... but doable.  Took a lot of thinking.

I look forward to seeing your plans for pedals and some photos.

And while you are generating that money.... send some my way  Smiley Wink Cheesy Grin.

best,

..............john

PS:  Thanks for the kind words on the "craftsmanship" bit.

Construction of Main Panel Support Structure

OK...... next in the construction installment documentation of my "little" project.  See earlier in this "Homebrew Simulated Cockpits" thread for what has gone into it before this.

This unit shown here will be the support structure that will hold two monitors on the lower shelf that will be the "glass cockpit" primary flight display in front of the pilot and the Nav display and the "backup" control instrument displays.  On the upper shelf part the glareshield will eventually be located projecting out over the front surface ....and then on the very top of it all will go the outside display monitors.

Photo #1

...

Again as in the other stuff........ 3/4" MDF for the upright sides and 1/2 MDF for the shelves.  Pine furring for the attachments.  All is "screwed and glued".


Photo #2
...

The two narrow strips are for the back of the unit....will be against the back wall of the cockpit under the "windscreen"........ to add structural integrity to the "legs" of the shelf.  They will get covered from the inside later to shield them from view from the pedals side of thngs.


Photo #3
...

The holes are again for wiring passthroughs...... and are lined up to match the holes drilled in the adjacent shelf structure.


Photo #4
...

Photo #4 shows the completed unit.  It sits to the immediate left of the other shelf unit (shown in prior posting) and the two butt up tight together on the common vertical wall.

To the left of this unit will eventually be a side wall armrest type console that will have some controls and the sidestick mounted on it.  It will buttt up to the front panel edge alligned with the left side vertical support.  The "corner" area that will be formed by the two modules will be a space that will contain pieces of cockpit support equipment and electronics.


So...... that's where it all is for now.  Next step will be to add the panel "facing" to the whole thing that will form the panel backdrop that the various instrument modules get "screwed" onto.

Of course in the case of the "glass cockpit" stuff....... they will actually be holes showing the monitors displaying the instruments behind the panel shield......... with a fake "mount" put on the front to increase the realism.  Eventually I MAY get some real instrument modules to augment this.... but that will be WAY down to road.

Cost for this part is about $15-18 USD in wood and screws and glue ..... and maybe 2 1/2 hours of time.

best,

.................john

Major Simulated Cockpit Programming Breakthrough Tonite

I plan on utilizing a bunch of "glass cockpit" features in my homebrew cockpit.  This basically means that you "hide" a monitor behind a wood or plastic panel and cut holes in the wood/plastic surface thru which you can see "gauges" that are actually on a monitor screen.  This cuts the cost of stand alone "instruments" and the associated I/O interface cards dramatically.

I am using a registered version of FSUIPC and WideFS to put the glass cockpit system onto a network that will "run" the cockpit.  I have also downloaded the FSUIPC SDK and have been looking at it with an eye toward developing some possible custom stuff.

There are a couple of well developed "freeware" glass cockpit setups out there that I have found so far.  Right at the moment I am "partial" to likely using FreeFD in my setup.  However...... while it certainly is GREAT as it sits....... there are some functions that I can envision that I want to implement that it does NOT (yet) have.  Since I am creating a "generic" cockpit...... I don't have to have exact Boeing or Airbus displays.

I also own the Visual Basic 6.0 professional development package....since I have written some very basic programs for my business.  In the FSUIPC SDK there is information about developing programs to interface with FS200X and FSUIPC in Visual Basic.  Great.

So I played around tonight to see if I could figure out how to get real time infomation out of FS2004 using FSUIPC and VBasic.  There is a great set of VB modules supplied in the SDK by Chris Brett that set the groundwork for accessing data.  That level of programming would take me a LOT of time to arrive at if I ever could have.  But it is there for you!

Making a not too long story even a bit shorter.......

I DID IT!


One example of a "glass cockpit "gauge" that I want to have available as a separate item was a square red "Stall Warning" light.  So I went in and using the docs.... found the hexadecimal address of the stall warning flag (1 byte at &H036C  with 0=OK  1=stall) in FSUIPC and wrote a short VB routine to definitively tell me that the plane is stalling.  It worked first try!  Smiley Cheesy Grin  The warning popped up in my little VB module just as the stick shaker started shaking and the stall warning light went off on the virtual aircraft panel.

This little test.........that took an amazingly little amount of time to actually figure out and write..... now shows me how relatively easy it will be to generate a lot of different types of glass cockpit gauges I might want.

I am NOT a highly skilled VB6.0 programmer.... if I can do it ........ most any "computer literate" person can learn to do this kind of stuff too.  The code by Chris Brett gets you pointed in the right direction.  (Thanks Chris!)

I'm pumped!


best,

....................john


PS:  You can download the FSUIPC SDK from Peter Dowson's site to take a "look see" for free........ even if you do not get a registered version of the FSUIPC program first.

Great work on the VB gauges there John, sounds interesting - keep us posted!

I've decided to hold off on the rudder pedals for a while (I need to get some other stuff sorted first - like makinga new chain device for my bike, I managed to crush my other one yesterday!  Undecided ).


I've decided to take some time to design my cockpit properly. I know I want a glass cockpit, probably with Boeing style gauges, purely because I prefer the look. I'm in a quandry about how big to make it. I think maybe full size, but with blanked instrumants on the FO's side is the best way to go, otherwise creating a full 180 degrees+ view will be hard to create. I found a picture of the sort of thing I want to do on the web, I've reproduced it here:
...


This design looks ideal, but I'd really want to use a large projector for the forward/side views. Maybe I'm thinking too big? Has anyone here ever used those 3D goggles? Are they any good?

I'm still trying to think of where to put it all. We have a converted attic room here that would be ideal, but it's a bedroom at present. I need to come to some sort of arrangement with my parents first, my mother won't be happy about loosing the space, and my father will be concerned about the fire hazard I'm sure. Time to move out maybe?  Roll Eyes Grin

Some facinating stuff going on here guys.

As the original post was about whether it was worth having a forum for this - well looking at this I would have thought it probably was.

A forum would ensure that this great stuff is not lost & will be evident to a wider audience.

If you want one - tell me what, where , etc....

I'll be ditching some of the un/little used forums soon so there'll be plenty of room on the page Wink..

Thanks Pete.

We promise not to upload too many pictures of our work!

As for exactly where it should be, you're the boss-man.

Thanks again.

PS Sarah and I will enjoy your bottle.  It's a pity you missed yesterday!

Ric,

That photo you posted there is very much where I am headed with my cockpit........ except just not even HAVING the FO side of things at all.  I just can't find THAT much space in the house at the moment.....and no one to SIT in the FO position anyway.  My "modular" design is such that in the future I could add the FO position just by duplicating what I am building on the left side.  You might think about that.

The "fire danger" part you mention I had already thought of relative to my OWN safety sitting in a wooden box full of plastic coated wiring and electrical gear..... not to mention the whole house.  Luckily I AM (supposedly) the "mature adult parental unit" in the house..... so no mom or dad to "satisfy".   Wink

Like a normal aircraft.......  I already decided that the cockpit has to have some sort of REAL fire warning device.... ... and some means of general REAL fire suppression.  The minute it goes fully "enclosed"..... everything changes a bit, I think.

I will mount mini smoke detectors inside a couple places in the unit with their power supply lines tieing into switches on the overhead panel, with LED's showing their status.  They'll just use their normal alarm sounds. 

For general protection, one of them will remain on even when the unit is powered down.  The power to my unit will come thru one master switch, and the whole thing will be FULLY off when not in use.

Fire suppression at the minimum will be having a large ABC type fire extinguisher in there within easy reach.  I may set something up more like the suppression used in a commercial kitchen with pipes taking stuff inside the panels.  That will have to wait...... very complicated to do right and to have a good "failsafe".  I could set it up to have a solenoid actuated valve trigger off of the alarm pulse on a smoke detector...... but a single false.... and some expensive computer stuff goes "bye bye"  Cry.

Thanks for joining in here...... makes me feel a little less "nuts".   Wink

best,

..................john

Just a thought John, but if you could put in an extinguisher system you could also put in a dry ice system.  Very handy for CFS sessions....

Pete,

Thank you........thank you....... THANK YOU!   Smiley Cheesy Grin

I think this subject as a "forum" will nicely compliment all the other stuff that is going on here ar SimV.

I think that where it goes is completely up to you.  My one suggestion is that it might sit physically next to the hardware forum...... since, as Will pointed out a while back,....... when all is said and done...... you got a big whopping piece of hardware sitting there  Wink.

The exact title is kinda' tough. 

Some quickly thought out possibilities:

"Simulated Cockpit Construction"
"Simulated Cockpits"
"Homerbrew Cockpits"
"Simulated Homebrew Cockpits"
"Simulated Homebrew Cockpit Construction"
"Cockpit Construction"
"Homebrew Simulated Cockpits"
"Cockpit Hardware and Software"
"Cockpit Construction"
"Homemade Simulators"
"Homemade Simulated Cockpits"
"Homemade Cockpits"

and of course........

"Large Complicated Box Into Which You Pour Money"


Will......Ric... Professor... BaileyGirl......Hyperion.....Fido Andrew....Polynomial.......others..... chime in with suggestions, please.

best,

...................john

Will,

Thinking on that further about CFS..... (which I have never flown).........

With the FSUIPC interface ...... my guess is that there is a variable about "aircraft damage" or two hiding in there.  You could used some Visual Basic code to monitor the status of one or more of them and then send a pulse to an I/O interface running off of the parallel port or the serial port or even the USB port to activate one or more devices in the cockpit that do a Disney-esgue "special effect" like simulated fire in the cockpit.

For someone who was good with both hardware and software.... probably would be pretty simple.  But that is NOT me  Wink.

best,

.................john
