Same amount of evil yesterday the same amount i pushed forward.
Throttle engines and clutches remounted in better positions and also potentiometer with sprocket to read flaps.

The real aircraft has resistance, but i like the feel of flaps without any so i keep it this way. I might add a clutch if i want more tension.

Uln2803a testing.

The orange and black cable is overkill, the yellow cable said "poff"! Quite the smokecloud! Hehe. I knew it before i turned the power on but still had to test it...

I need a good awg size for 5v and 12v and 28v with max 2,5 amps and not longer than 20cm...

The boeing cables are 28v and still very very thin! Must be excellent heatshield in those cables.


Uln2803a rocks!


Let there be backlight!


I decided to cut out all the stuff from the panels i dont need.
First i didnt want to due to the masterpeace of installation from boeing, but then i figured, this part will never fly again, and i want a clean setup with the IO card inside and a nice panelmounted usb, 5 and 28v and ground connector.

So i took the plunge...

I need to figure out how to remove the korrys so i can setup with clean cables with exact length i need and thin canples for pushtest.


New panel arrived!

Upside down without gauges, but hey! 100$!


Cables cut and identified. Keeping some extra cables if my current ones fails.


Moment of truth...




12v or 28v and ground + usb cable. Thats it!
All mapped and interfaced. Glad i decided to put the io card inside!

Anti ice panel complete with push to test function on the korrys!



Ah man! i love the x737!!!
it has a float value of 0.0 to 1.0 of the announciator brightness!
it will be supereasy to map it with my uln2803a driver!

godspeed the x737!



Work continues!
After the smokefest yesterday i made custom duponts with the original boeing cable, so now i know the awg is ok!

The anti ice i tear apart evrything, but i will change the approach and use the current connectors. Drawback is that the teensy is on the back, but no more hassle with the wires.

Flight recorder arrived today! Aft overhead 80% complete.


Ladies and gentlemen...
We have ourselves a moving left throttle...


Created a youtube channel to keep track of progress.

Finalizing wire setup for the throttle pots and motors

Both throttles moving...

IRS selector position two pin multiplex code is cracked!



if i would use fsx instead of x-plane we could now hear my final words before OOM fatal crash! Hehe


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

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...
