Title: 737-800 Arduino X-Plane Build
Post by: kurt-olsson on September 06, 2015, 05:39:47 AM
Hi!

I thought i should start this thread so i can keep track of all my progress and my images.

My build is targeted to be "budget with no compromises" =)

Some things i can´t build myself or get the panels for, so i just have to buy them. I think now these items will be:

Used TQ throttle
Seats
Yokes

Function is will take care of later:
Yaw damper, Authothrottle auto disengage.
Startswitches 46% disengage.

But all the other items i plan to make from Simworld Panels.
I have seen lots of panels, but i think they are among the best i have seen.
And the support from that company is great, very nice people!


So first off:

I wanted to start with the hardest part, because if i could do this i think lots of other things will be easy.
My build is based on Lots of Arduino MEGA cards and X-Plane 10.
The communication is based on COM port with Serial communications and a small program that i made in C++ for talking to X-plane.
The architectural build is done, so i just have to continue refactoring and make more datarefs handeling in the program.


Part 1:

MCP Build

I ordered the Simworld MPC panel, looks great.
I have some CTS 288 rotary encoders (i had to drill in the backpanel to make them fit)
I have ordered some knobs from acvdesign (custom drilled to fit the CTS 288), havent recieved them yet, think i will hava a problem with the length of my encoders being to long. =( need to cut them or replace them.

For the Korry switches i did something cool. I used 2x2 black Lego bricks. Becuase of the ring in the middle it cuts the lights from the display text and the Led engage light.

I have ordered the switches aswell for the Flight Directors and the Autothrottle. I have also ordered lots of MAX7219 LED display to use for this MCP. Right now the display is RED bur i will try to find some White leds later.

Anyway sofar i have this:

Awesome work!  I'll be watching your progress.

 Question, is there a reason you didn't go with Teensy line of products with native X-Plane support?  Way more powerful than the mega.  Just curious.

Hi and thank you.

Haha i just got the feeling that i missed something with the teensy board! ;)

But i like the idea of having total control of the code both on the arduino and my c++ program, my plan is to support both the 737-200 flyjsim, x737 and the upcoming ixeg 737.

With that in mind i like the controlled code. Arduino has lots of good libraries also for led and encoders.

But i will definently look at the teensy card, my impression was that the arduino mega was more powerful.

I havent started to solder yet so i can still switch cards, i will do more resource of the teensy.

Thanks for input.

By the way, love your 737-200 sim. I admire your electric skills to get all those gauges to work. Looks amazing! The -200 cockpit is amazing, i like it better than the -800 due to more "manual".

This is one fat switch. Just hope that my arduino card van read it? Where is the ground? Only two connectors!??? Why?
Title: Re: 737-800 Arduino X-Plane Build
Post by: 727737Nut on September 07, 2015, 07:46:34 AM
That switch is what they call a SPST or single throw single pole sw.  Just hook one side to the arduino gnd and the other to your input pin.  You can tie all the your switch grounds together to one point to make it easier.

Thanks for the kind words on my -200 sim  :)

As for the Teensy, it uses Arduino code so you full control over them as well.  ;)  Just no need to write the interface between it and x-plane as that part is done. Is is an I7 compared to a PentiumI when you put it next to a Mega ;)

Post by: kurt-olsson on September 07, 2015, 09:32:53 AM
Ah. Thanks for the switch info, that saved me lots of google-time. =)

I have looked at the Teensy X-Plane API and it looks that i have written 99% same library! haha =)

The teensy card look really good, but i also like the connectors on the arduino that dont require the soldering, i saw that you can add adapters for it to make it the same, but i will continue with the arduino cards i have right now and see what the future has to bring. =)

Post by: 727737Nut on September 08, 2015, 10:30:46 AM
The really cool thing about the Teensy is that you can disconnect it during a flight, re flash, plug it in and it works immediately! Very handy when fine tuning code as no need to reboot the sim.

My Project took a a real hit yesterday.

My soldering skills.... oh my god are they bad or are they bad? I doubt i will be able to solder all things together...  :(

should i use Heatsink for the resistors + Led. And how do i summon all the ground wires easily.

I would like to have some "ground-metal-rail" on my cardboard that i can connect all my cables to...

I would like to post my soldering, but you would laugh so hard that i wont post anything. =)

Post by: mickc on September 09, 2015, 08:28:01 AM
We all have to start somewhere Peter!

Just get some cheap components and practice.  There a lots of good Youtube videos out there that teach you how to solder.
After a while you will get the hang of it!

My first attempt at soldering looked like a bird had taken a metallic shit on the board :(

A common method for ground wires it to connect them from one component to the next in a daisy-chain fashion, so you have one wire that goes from switch to switch instead of individual ground wires to each of them.



Title: Re: 737-800 Arduino X-Plane Build

Soldering skills.... It does take practice....

As you build you'll notice an exponential accumulation of wires that need to be grounded or otherwise connected to a power source.

I have about 12 of these in my sim:
(http://www.slagcoin.com/joystick/pcb_wiring/block.jpg)

They work beautifully.

Thanks for your kind words!

-"My first attempt at soldering looked like a bird had taken a metallic shit on the board" HAHAHAHA I laught so hard i almost wet my pants! Metallic shit! heheh

Ah smart! connecting all the ground component by component seems easier than my "rale-thing".

By the way. My Teensy 3.1 is now installed and all the libs in place. Got the sample sketch up and running in 5 minutes!
Grade sofar 5/5.

Looks like the FlightControls is running async on its own core, that was my next step in my API that i was coding. Luckily i was told to try this instead! =)

You can see here in the bottom center the power distribution. After it is all said and done I am still in a bit of shock at how many terminations there are to power!
(http://anthonyscottphotography.com/img/s12/v176/p433557612-6.jpg)

It has:

2 Ground rails
1 5vdc "Always On" rail
1 12vdc "Always On" rail
2 12VDC "Switched" power rails (Only 'on' after I turn on the BATT switch)
1 5VDC   "Switched" power rails (Only 'on' after I turn on the BATT switch)

The switched rails are controlled by a relay card that uses TTL logic inputs.

The workflow for the BATT switch:

BATT switched connected via joystick card directly to X-Plane (Leo Bodnar's BUX card) --> XPUIPC connected to X-Plane --> RUSCOOL's 64-Output card --> Turns on Relay channel on Relay driver card --> connects 12vdc power to Rail(s)

Seems convoluted. Why not just use the switch itself to provide power to the 12VDC rails? I tried that but I also wanted the systems logic that turns on other related systems within the aircraft (Like flaps won't work unless BATT power is on)

Another thing to keep in mind is current draw. Make sure those primary power cables are thick enough to handle the load. Also make sure your power supplies are beefy enough. I've blown up more power supplies than I care to admit because I underestimated power requirements.

Some new stuff came in the mail today. Lots of max7219 drivers and also my mcp buttons from lima,Peru!
Will have to sand the buttonholes abit then they will be perfect. One bad thing was that the vs wheel was to big! It will not show so much and will be hard to scroll... :(

The last hurdle now is the leds... It will be a pain-in-the-beeeep to extend 12x6 cables... And i also have to mount the leds somehow...

Have you entertained using a stock Printed Circuit board? That might make for a better MCP backer and allow you to mount LEDs the way they need to be.

Maybe something like this...
http://www.ebay.co.uk/itm/like/121447132127?clk_rvr_id=897557081744&item=121447132127&lgeo=1&vectorid=229508&rmvSB=true (http://www.ebay.co.uk/itm/like/121447132127?clk_rvr_id=897557081744&item=121447132127&lgeo=1&vectorid=229508&rmvSB=true)

Then you could terminate all connections on your MCP with an IDC male plug, then simply attach a ribbon cable that also connects to your controller card.

http://www.protostack.com/connectors/idc/idc-male-connector-shrouded-header-10-pin-right-angle-leads (http://www.protostack.com/connectors/idc/idc-male-connector-shrouded-header-10-pin-right-angle-leads)

I also use wire-wrap wire for interconnecting components on a board such as the MCP. You could use thin-gauge wire such as 22AWG stranded, but in the end, wire-wrap wire makes for a much cleaner layout and fewer solder blobs.

Rays:

I looked for that pcb material but i didnt know the name for it. Wish now that i had seen it earlier...
I will try to implement next module with both the pcb and the wires you linked. It will also be easier since the mcp is so wide, other modules will hopefully be smaller size.

Thanks for your tips, really appreciate it!

Yepp! Teensy here to!
I am using the max7219 driver that you can serial connect, it has a din, clk and load pin. So three pins to rule them all! (Lord of the rings) hehe

I really like the part where i can upload to teensy without restarting the sim. Its pricelesd.
Title: Re: 737-800 Arduino X-Plane Build
Post by: kurt-olsson on October 22, 2015, 09:32:35 AM
Update!

Pheeew. Lots of new stuff. Every single button and switch is now mapped and the last thing to do is the backlight multiplexing including the leds for the button titles.

One really negative thing with this mcp is that its more challeging to solder and fit tight components than actually hook it up. I hope this will be the most tightspace module on the 737, otherwise i probobly will give the hobby up... :(

Well enough of that, my leds are installed but it resulted in a strange problem with that the last daisy chained max7219 is loosing power and is unreliable.
If i skip the first three max7219 the last one shines strong and reliable so i think it is a power/daisy chain problem.

Anyone have experience with more than 4-5 max7219 in a row?

This is the problem:
Title: Re: 737-800 Arduino X-Plane Build
Post by: kurt-olsson on October 22, 2015, 04:40:14 PM
Solved the LED problems.

https://forum.pjrc.com/threads/28526-Teensy3-1-losing-my-application

It turns out when, manually booting, the Teensy is really fast so the instanciating of the LedControl is "sortof" working. But if i put a deplay for like 1 sec and then reassign them afterwards then the MAX7219 works stable with all the serial connections. (now 6 of them)

Thanks for the comments!  :)

I will be glad to help. The max7219 drivers with the ledcontrol library is supereasy. Just use print digital or chars on an indexed array with nr of devices and position of what led to write to.

It will be super for your CIVA that also includes lots of dots and both N and S,W,E if i am remembering correct.

Update!!!

My MCP Has started to get a complete update!

After gaining some experience in building an MCP, i removed all the wires and started from scratch!!!

What i didnt like with my old setup and how i am improving it.

Wire mess: wires right to left, now i will use two teensy, one for right cables and one for left cables. That way it will be more clear of space.

cable thickness: i used too thick cables, multithreads cables, very hard to solder and thick cables makes it tought to get some space to see anything after a while with lots of cables. Now i use superthing singlethread cable which is sooooo easy to solder!

ground: i used to go component by component. But this way it is much harder to find ground errors, bad solderings or a broken cable.
Now i wire all components with its own ground cable and then use a PCB Board to connect them, it will still only be one ground cable to the teensy board.


Max7219 cables: a mess with hardsoldered wires. Now i use a connector, that way i can remove the cables if i need to search for other errors or resolder other things. without being able to remove these cables i cannot do anything without burning the cables with the solder-tool.

Finally, i will order white Leds from Ebay. If the Simworld panel is that great, i really need to have the white leds like in the real MCP.

When i use the smaller cables, it will be easier also to attach the LED-strip that will work as backlight.

Some picture to show my mess. =)
 

My EFIS Panels are in the works aswell. Will post new update when i have installed the 3mm Leds.
Title: Re: 737-800 Arduino X-Plane Build
Post by: kurt-olsson on January 18, 2016, 04:22:02 PM
Also. i will use Dupont cables and connectors. I have bought a tool for this. So no more taping the extensions! This makes the wires have exact length to the teensy board as well.

While waiting for some motor parts, i am starting to setup a "final solution" with a adafruit pcb. Really great board. I will solder some connections right to it, but i got to test the screw-connectors and they work great.

A/t disc -both sides complete
Toga both sides complete
Fuel cutoff idle -both complete.

Still to hookup the trim switches and fuel cutoff "off mode".
Add the parkingbrake test switch and i think all switches are done.

While waiting for parts i am continuing on my mcp backlighting. Not fun at all and superhard to get even lightning in the simworld panel.

Really great thread to follow. Thanks for loads of practical advise.

Would it be more practical to push wires into the Adafruit board from below, solder from above and then trim any excess? This might help wire distribution, access and air distribution. Easier to get to the teensy as well.

Thanks for your kind words.

Yes, it would be easier! Hehe i will def do it on my next board. You learn something every day.

Thanks! :)

This will be my drive for the throttles.
Lots have changed to string pots, but for the price, i want at least try this solution.

The gear thats driving the chain is still missing

Cheap String pots that we use, work great

Title: Re: 737-800 Arduino X-Plane Build
Post by: kurt-olsson on April 12, 2016, 01:44:51 PM
1 turn only, its a panel pot. If i cant use it due to gearing or too large movement i will switch it for a normal pot and calculate the movement and position in the software. The sim will always boot up with throttles at idle.

I knew it!
Replacing the red segment displays to white like the real boeing made a great improvement.

The backlighting is a P A I N!

Dont think i will improve it if its not good, its just tooo tight of space in the mcp!

Theottle progress!
Left lever is moving.

Right now with my gearing and 9v battery it takes about 6sec from idle to full power. Hope to get extra speed with the 12v power supply.

My main problem now is the wires. I need one with a steel ball that locks into the levers. Right now i tied a knot, but i dont think its working that good.

Kurt, when I did mine I used a cable ferrule from Home Depot(see attached picture..you would just use the single barrel one).   You just smash onto the cable with a hammer.  You can then tap on it to shape it more ball like and will do the trick.  Make sure to safety wire it in place like the original ball was so it doesnt pop out of the slot..

You can get the correct balls for the cable from Aircraft Spruce 
http://www.aircraftspruce.com/catalog/appages/sa110.php (http://www.aircraftspruce.com/catalog/appages/sa110.php)

You would need the SA110-3 as the bore in the thrust lever cable wheel is 1/4"

This will need to be swaged onto the cable (or you can smash it with a hammer, as Scott suggested :)   I tried with a hammer, but  these balls are quite solid and i couldn't get it to grip properly.

Any marine/boat repair place should be able to swage the ball onto the cable for you if you mark where it has to go.

That being said, there's obviously lots of ways to do it, I initially used cable stops like these:

(http://contentinfo.autozone.com/znetcs/product-info/en/US/drm/03336/image/2/)

I was worried they could come loose though, and that would mean a whole lot of disassembly and tightening, so I went for the solid option.


I guess a $1 ball getting shipped to Europe is another thing to consider, but you could be able to find them locally.  I got mine from Aircraft spruce as I ended up ordering a complete new set of screws/nuts/bolts etc to re-assemble my TQ as a lot of the heads were starting to round off and I wanted it to look as new as possible after the time & money invested :)

Yeah, this forum is the key for progress. I watched Scotts youtube-clip of the throttle conversion like 200 times before starting the work of mine.

I cant imagine what James Price and the other went through building the sim in 2002 without an existing forum for help! Hehe

Peter - not sure if you have these numbers: Throttle lever movement is 13.5 degrees / second. So a full throttle from idle takes 4.4 seconds.

Opencockpit korrys installed! For anyone who is building a mcp, BUY these korrys!!! :)
Much much better finish than DIY and really easy to connect.
I doubt if i can remove the ring on these buttons without braking them so be sure to install them correct!

I got my VOR LOC switch with faulty text so i am waiting for them to send me a new one.

Update!
Put a few hours in today for a new backlight tactic, and this time it was an epic win!using acrylic to mount encoders and be able to fit the ledstrip on the front. It will stick really great on this material.

Hopefully this will be the end of the mcp build soon! :)

Bad thing is that i glued some encoders on the efis panel and cut the shafts too short so i need to buy 4 new ones...
Title: Re: 737-800 Arduino X-Plane Build
Post by: kurt-olsson on May 30, 2016, 03:09:58 PM
New plan for backlight!
Skip the ledstrip because its to messy and hard to mount.

I will make a thin pcb board with bulbs that will go direct into the panel.
I have drilled 3.0mm x 3,5 mm holes in the back of my mcp panel.

Came reeeeeealy close to drill through the panel once but luckily i didnt... :)

Hope the bulbs are wide-angle, because i think that is one key for good backlight.

Post by: kurt-olsson on June 06, 2016, 01:46:47 PM
Was on an Ryanair flight yesterday and got a chance to talk to the pilot for 5-10 minutes after we landed.

This resulted in motivation bump! Man, the cockpit of the real 737 is a beauty.

Work continues on the throttles...

Issues now.

1, dont know how the levers resistance is in the real aircraft. I need to tighten my polyclutches preeeety tight to be able to pull it back from full power to idle.

2, need an aligned dc motor shaft that supports the "end shaft" mine is made of another engine-mount and some plexi. But i need something that aligns it 100%.

3, steel ball of cables. I will bite the bullet and order some steel ball for the cables for 1,5 dollars each and the shipping is 45 dollars!!! ????
But this is so important for the feel.

75% of the mcp backlight done.
Dont think you can do better than this on the simworld panels.

Tried both paint the backside and drill holes in the panel but that did hardly improve anything.

Looks like MCP version 2098.45 is a keeper. Only took a year! :)
Advise: Do NOT build the MCP yourseft, do all other panels, but not the mcp. Too much frustration and the cost for this ended up on 800 euros with all rebuilds.

Hi Peter, you have been too quite lately. Did you test your MCP with  x737?
Have you been able to use the avionics directly without having to use a suite?

Hello my friend! I am just about to put in an update! :)
The MCP is all done mounting and about 70% programmed (that part is easy)

Found out that arduino sketch has support for operational conditions!!! That reduced all my code by 40%. Hehe

Efis is also getting some update, still problem with some mounting but i am glad i have solved my main connection solutions by using terminals, soooo stable! :)

Also i now use aircraftbulbs with psu for backlight, so that task is also completed.

I run my mcp with the x737, works like a charm. But i think the x737 has some strange behaviour with its autopilot, but thats on the plugin side.

I am thinking about hooking the IXEG 737 up since the autopilot is the same on the 300 model.

If you want the code i can mail you.

Cheeers!

Ooouh, that means i have to remove the knobs and the buttons to be able to remove the current switch =) hehe

I am thinking of looking after a solenoid switch, of all the magnetic switches the A/T is the most important.

This cable is 2mm, boeing original is like 2,3 and i ordered also 3mm, but that was too thick to fit the steel ball.

I tried smashing it on with a hammer on my 2mm cable. I thought it was a failure because it twisted the cable, but it actually worked really nice because twisted it locks in better.

Now i have to figure out how to use steelwire around the balls??? Its really tight so i dont know how to wrap it around... Hm...

I used a split lead fishing sinker and squeezed it all around the cable then used a punch to seat it in the cable drum.  Worked like a champ.   It takes a special tool to crimp that steel ball to the cable..

90% done. Backlight is fantastic in daylight even! So happy with the backlight! With my mcp i did the mistake of having to large gap between the bulbs... But i dont have the energy to disassembly it one more time, it will do for some years anyway.

Capt EFIS almost done. The buttons came out really really BAD!!!

The finish and feel is aweful but itl have to do untill i find a complete "efis button" Always when you try to make your own buttons they come out cheap and bad feel (at least for me. These has leds behind them so they should light up when backlight is on

I replaced my drilled rotary with an E37 Elma dual just because the feel of my switch was so bad.

Peter,

I've used these to tidy my resistor ladders, they used to be available as a pcb only, but alas no more, which was useful for me as I used them with 8 way rotary switches for my transponders .
I think I had to solder a wire on to one of the pins to get this to work as I required three connections for the resistor ladder.

Not to mess you up Kurt but did you measure the width from side to side with those motors to make sure they will fit within a pedestal.  The NG pedestal gets more narrow at the bottom so even though 3 bays wide it is tighter at floor level.  If using a 2 bay gets even tighter.

Post by: kurt-olsson on August 10, 2016, 05:28:55 PM
Your right, i am aware of the problem after i bought the motors. Sadly there is nothing i can do about it except build my own square radiobay. If just build as a box the motors will fit

In some areas i have to compromise :(

Post by: XOrionFE on August 10, 2016, 10:09:06 PM
No worries

This hobby is all about compromises.  You could still build the box to fit but make the very back end few inches have the bottom profile and nobody would ever know the wiser.  That is one of the benefits to building some things yourself.

By the way. All the korry switches are smooth as kittens except one.

And should i do that to all switches? (That is toggle)
Title: Re: 737-800 Arduino X-Plane Build
Post by: mickc on September 08, 2016, 07:04:18 AM
Definitely would not use oil on the switches!

Most of the toggle switches will be sealed anyway.

You should use a switch cleaner/lubricant designed for the purpose
I use this, you should be able to get something similar over there.

https://www.blackwoods.com.au/part/03065243/crc-2001-switch-cleaner-lube-aero-300gm (https://www.blackwoods.com.au/part/03065243/crc-2001-switch-cleaner-lube-aero-300gm)

With the Korrys, you can just pull the switch head straight out and clean it up.  A little dry silicone lubricant on the sides of this part works well.

You can get the pointer of the gage move full deflexion by applying a tiny voltage switched by the test button.

Cooooooool!

 I didnt even think i could implement this, only the two buttons.
Will use pwm and see if i can simulate some movement. Thanks Jack!

It would be cool to use a sound-sensor and map it to the volume!

Fuel idle positions
Parking brake switch
Speed brake solution
Horn cutout switch
Trim wheels ( i am not sure if i want to implement this noisy stuff)
Trim indicators.

Thats it! Rest of the switches and funtions are connected.
I am starting to see the end of the tunnel for the tq.

Loads of fun.

For the parkingbrake i will implement flaps2approach solution. I will not implement push rudders to release, maybe if i get some rudders. Hehe

The speedbrake will be tricky. Need motor and clutch for this one i think. If i use servo i cant move it manually...

Hi,

I now regret starting a similar project recently and have almost given up.

Perhaps your circuit board is in a better condition but the one which I bought had several of the foil domes which are the switch contacts broken or missing. These cannot be repaired or replaced and even one broken switch renders it pretty much useless.

I then had to design, etch and solder a replacement circuit board, I'm now using the 5th replacement board. Although the buttons close to the edges work, buttons in the centre don't due to flexing of the circuit board and I'm trying to find a way to make it more rigid and get the spacing between the buttons and circuit board and circuit board correct.

It is nevertheless interesting to see how the buttons are backlit as well as the general design of an OEM part.

I was also unable to find pinouts of the connector even with the assistance of experienced and knowledgeable forum members.

Oops., that dont sound so good. :(

My plan is to:

1. See if i can just replace the exec button and interface via pins out.
2. Remove the circuit board and try to hook up the switches manually.
3. Remove all and even try to fit new buttons (or use the caps of the fmc). Maybe build custom backlighting if lightplate is broken (but dont think so)

I think my circuitboard is in pretty good shape but havent begun identifying pins with the multimeter yet.

How did you remove the circuitboard? Can this be done without braking it?

Usually the "homemade" stuff turns out bad and bying FDS would be better. But in my case i cant use FDS since i only use x-plane. Would like to see pins out on their plug n play. And this OEM cost me a 1/12 of their plug unit so i will at least give it a try.

Lets keep in contact if we find good progress. :)

Post by: paulnd on January 05, 2017, 04:30:33 AM
There are 2 circuit boards, the outermost is the backlight and the inner contains the membrane switches (I think that's the correct term). Both can be removed by undoing the tiny screws. Once the circuit boards are removed, you'll have the backlight "block" which is attached to the buttons.

Perhaps post a photo of the back to confirm that it's the same as mine.

Thanks Bernard! I will see if i can make something out of it.
I took away the lightplate and was disappointed because i cannot use multimeters on the silver rails to identify the pins.

I would like to be able to remove the circuitboard and see how it looks.

If everything goes wrong i should be able to multiplex the buttons and still use the backlight.

Post by: paulnd on January 05, 2017, 11:54:54 AM
if you undo the screws on the front holding the EXEC frame and the 2 annunciators (MSG, FAIL etc) then you should be able to remove the membrane switch circuit board.

There is nothing then holding the buttons and backlight "block" in place so be careful if you turn it over once the circuit boards have been removed.

Back with a plan!

I am down to my last alternative: manual cables and new micro pushbuttons.
I will replace the springs with actual bushbuttons!
That way i can still insert bulbs and use the original "glass-holders" and "caps"!

The exec button will be replaced and also a new potentiometer.

Really hope there is a lcd screen that is right size! Maybe i can use the lightplate or i will have to manually indert the bulb in the board.

The CDU at swiss-sim is about 900$, i got this for about 150$ So there is lot to try before adding up to that price, but i do agree with you that it is best to buy complete stuff.

But i think i will actually get this to work! Some microswitches and new bulbs and a custom pcb should do the trick! :)

Fmc face completely disassembled. Will do some cleaning of all parts before assemblying. Lots of springs were damaged and the caps were missing in places so this unit was doomed from start to work 100%.

The OEM switch has about 5mm spring and a tacticle click when pressing it. I will replace them with tacticle switches, the length of the "momentum" of the button will be shortend but the click is the same. Much like the FDS plugnplay units.

The backlight is a pieace of art (or really not due to how complex it is)
Small holders in glass that projects light and the backlight that is painted black to absorb the light and amplify it where the buttons are.

Next up will be to test some other switches then drill a pcb board where my new switches will fit in the original pinholes.

Yes sir.
Honeywell part number is 15PA90-6W
These are easier to find/buy as you can get them through normal electronic distributors like Mouser, Digikey etc.   

I got mine from Online Components, and with the qty discount for buying 30 of them they were a little under $12 each.   
That price looks to be a bit under $15 now ( i got mine in late 2013)

Other places a quoting up to $44 each!

I used Online Components for all my Honeywell switches, caps and some guards too.

Yes. These are push switches. So they have a circuit for it. The problem i might end up with is that the light needs 24v and if i push them, that circuit is the same as the light so i am afraid i might burn my teensy controller (max 5v).

But i am sure this could be solved with some kind of resistor etc...

The ones you show in your pic are the standard annunciators, they have the push to test function that grounds the bulb to illuminate.
Normally terminal 1 (centre) is connected to 28v,
Terminal 2 is switched ground (to trigger the light)
and terminal 3 is constant ground for the self test.

The actual fire & MC ones have 2 separate microswitches attached to the back of them.

You can still do it with the ones you have but you will have to use an I/O card that accepts up to 28v and do away with the push to test.  The Phidgets 0/16/16 worked when I tried it, but as you say, you will need to interface it differently if you use Teensy.

Post by: kurt-olsson on July 16, 2017, 08:46:34 AM
True true, i will also see if i can mount a seperate switch behind it that gets pushed by the rod itself. That way i still can use teensy and get the real feel of the oem push. I think i will try this approach first.

Pull off the cap and use a fine blade or screwdriver between the outer case and the square back plate and you can lever the plate out. 
Start on one of the sides that have the indents on them.

There will be a steel spring, glass diffuser and then the lens.  Careful popping it out, as they stick the the body and are easy to break.

When you reassemble, you may need to slightly compress the sides of the cap before putting it back together to give it some tension, when you open them up it slightly stretches the sides.

NG...since you scrap the logic boards...unserviceable parts are right for you - if you're serious about getting it NG...I'll try to see if I could direct you to the right guy or source you one myself.

Expect $500-$1000 for these. Good news ... APU Panels...these are technically one of the "Cheapy" panels in the NG market. I'll lookup some repair shops.

Thanks Youssef but my build willluse Classic Panels that i will convert, and the pure NG ones i will use Flightdeck solutions panels for. This is a solution that works for me to keep the budget tight.

But this does not mean i will stop follow your build and be envy of your NG panels! Haha :)

-600? Which exactly? :)

Dunno why people don't classify -600 as NG...there's no difference between most parts on the -600 and the -800. The part numbers are identical. My elec meter came from a -600.

Not a -600. 737-600s are part of the NG family. NG's are a lot more consisitent in terms of colour and appearance of their panels - not many variants per panel. No NG has a white overhead frame ... CL for sure -1/2/3/4/500.

Post by: blueskydriver on November 03, 2017, 05:22:14 PM
Hi Peter,

Not sure about your knob, but I do have some radios like that in which I could look at and help figure it out...can you tell me if there is a hex head bolt/screw or pressure fit pin in the knob? If nether, the knob is likely held by the pressed on fit; it's just pressed onto the rod.

In RC engines it's the same concept with removing the prop thrust washer. Using heat along with a pulley puller of sorts, the washer is slowly removed. You can use the same method, but without the heat aspects. You would just use the puller and do it very slowly because I am not sure if the rod could take a lot of force pressure from the front side.

Look at the two pics attached and you'll get what I mean here. Notice the puller on the RC engine, it would not be as tough on the rod as the bigger pulley puller shown by itself. That's because the bigger one will put a lot more pressure on the rod. Also, the hook sides might not be able to get in behind the knob very well due to their size and potentially slip off breaking the rod.

You could buy these items or even make something yourself using threaded rod with some nuts and a couple pieces of strong wood or metal too make the hook sections. As long as it pushes inward on the radio knob rod and outward on the knob it will come off, but just make sure you don't over do it by pushing the rod out the backside of the entire assembly.

They are definently pushed tight to a rod, so i think a pusher can be a solution. Lots of work for a little knob :) the top ones came off really easy.

Yep, wood works fine and the video you linked shows that well; however, wood might not be strong enough depending on how the pulley, knob or etc is put on. If heat and a strong pressed is used it’ll likely need that in reverse...heat and a strong puller device.

Before I purchased the RC one and the other larger pulley puller one (which can be used with 2 or 3 arms), I had one made at a local metal shop using threaded rod and an 1/16” (2mm) thick piece of flat steel. Basically, I just averaged the hole sizes by using the biggest prop washers and the smaller ones, as well as the crank shaft sizes, then they drilled out the holes and cut the slot prior to making the bends. From there the bends were made using a press or metal brake (bender), then they deburred and cleaned it...no paint applied because RC fuel is hard on painted metal, depending on the paint and metal used, so they left it clean, which still looks that way after all the years I’ve had it.

I know explaining something so simple might seem like over-kill, but it’s surprising how many things you come across that a puller of this sort can be used for; countless times I got this thing out over using a hammer or a pair of vice-grips...lol! Plus, it saved my fingers and thumbs many of times from the dreaded dummy mistakes of hitting them instead of the item or part needing removed  :o.

Attached are a some pics with measurements shown...

Unfortunently the rod sticking put is the inner rod, so i need to push the one that is fit tight around the knob.

This makes it impossible, either trash the lightplate to get access to the screws or i can just throw this item in the trash and learn from the mistake of beliving that you can change OEM construction. :(

Thats what i thought, first two lockscrews were superhard to loosen, the first one (on the other one) broke my custom gable-tool and the knob seems to be cemented on. Think this is because corosion or rust etc. Think this is from early 80:s.

Hey Peter,

Will you be using a hand drill or drill press? If you don’t need a perfect hole you can hand drill it, but for a nicer hole go with a drill press. Steel and Aluminum will drill differently of course, but the Aluminum could melt just enough for cracking to form later; especially, if the hole will be under high stress loads. So, just make sure the drill rpms are not too high.

I am no expert at drilling, but I have drilled holes in aircraft aluminum too be used in undesigned manners or for something the aircraft builder never intended...which is about everything...lol  ;D

Keep the posts and pics coming, it’s nice to see someone trying new or different things to solve sim building problems  :idiot:

Main setup: rails attached to the crosstube that fixates the pulleys and holds the bearing so i can tighten the cable without the pulleys sckewing/tilting.
The bearings is spareparts from the disassembly of the steeringboxes.

One major problem to solve!

The bearings of the crosstube is close to the pulley, so i wonder if its enough to just use the two upper holes. (See third picture). I know Scott made custom bravkets because of this problem.

Oh, and i pulled the yokes beyond its limit pitch 12,5 degrees.
Here is youtube link.

Both yokes mounted. Tomorrow i will fixate the right cablewheel and drill holes for the canle to go through.

I will then put some "stops" agains the crosstube when the yokes reavhes max movement. Then will the springs/gas struts be installed.

Yokework continues...
Made the structure more solid and also made a "stopper" at 12,5degrees from venter position. So now the yokes support themselves.

After investigating i think i will use rubberband instead of gas struts because people have complaint about the "neutral position" is to hard to pull/push from.

Also bought two more panels, pictures when it arrives.

Saw a youtube video on some dude making bearing houses in wood, so i thought i give it a try. Turned out 1000 times better than i thought, perfect fit and rock solid! Dont even have to get a second layer of wood thats stopping the bearing from moving out of place.

After a couple of hours the height is right and i can move the column freely within the limits. According to the design the spade and clevis should only come together about a cm.

Completed the second stand and secured the wheels. Tomorrow i will connect the cables and voila! Only potentiometers and interfacing left and that part is easy, construction is hard.

Snail progress...
Had to raise the structure 8mm more to get the spade and clevis to work better. Now i can rotate the yokes beyond 105 degrees without any metal structures touch. I was able to get the alignment perfect.

The screws thats securing the cable is not smooth, i am very afraid that it will break if i deassembly the cable back and fourth a couple of 20-50 times.

The final peace in the puzzle is to secure the plates that the wheels are on. Once the cable is tighten it has a tendency to move up in the air a bit. Need to secure it to the floor/structure somehow.

The springs are removed, hate that noise... will use rubberband or tennisballs or something.

Christmas came early!

Man, the condition of these panels is amazing! Looks new!

This is also a end of OEM overhead panels. The only ones missing is the NGs specific, these will be aftermarket.

Next up is to get hold of MIP metal panels. Anyone tried Simparts.de? I can buy seperate panels. The kits from Simworld and FDS has too much panels that i dont need.

More OEM stuff.
Found a NAV radio, but unfortunatly the screws on the knob is not tightened or busted. I will not even attempt a try to fix this. I had my fair (unfair) share of these old knobs. Will use the one on the right to atleast tune in one single freq.

Bought a -300 Panel, Lots of hardware for small money! Just the autobrake switch is worth threetimes the price for the whole panel in the aftermarket. Lots of Korrys and switches too.

Also found a cheap door announciator panel.

Just placed an order for a MIP with simparts.de. Looks total pro and i was sold when i saw that their MIP frame is identical to the real one. I was also able to buy parts of the panels so i can fit my OEM gear panel later when i find one.

I know that Simparts.de also is building for real 737 cockpits and wants 100% scale accuracy.

This will be the last part i buy for a veeeery long time.. My wallet cant take anymore hits this year. :) now i have everything for getting the sim 90% ready, no more parts untill big progress is made!

Damn this hobby is expensive...

I have to rebuild my throttle to be able to fit the motors.

Thanks.

Yeah, i cant belive it. After 2-3 years i have all the panels, seats and items i need.
Now the cockpit frame construction will begin.

Once it is complete i will take panel by panel and interface. This is my approach so i can fly a little sometimes with the parts that has been completed.

Base platform under construction.

Will mount wheel so i can get access when maintaining.
Key focus will be on easy access and being able to easily remove sections.

Platform with wheel will measure 42 cm of height. Still lots of height left.
Will prob go for lcd tvs...

Base construction 99% done.
8 casters each rated 100kg.

Each beam has cc 60 cm.

Will add a layer of 1,5cm playwood and also on the sides. (As suggested)

The yokes are almost complete hardware wise, installed the cogs for roll axis. Once my alps linear slide pot arrives i am done and the floor will come on hopefully. 😊

IF you can gain access to the head of the rivet, in most cases just drilling it out will allow you to remove them.

Don't remove them or if you do, save the document boxes.  Inevitably, one day, you'll need more storage...
I don't see how having them affects immersion.

The thing is also that both seats are FO seats, will prob try to convert it once other issues is done. but not right now. =)
