Re: home made tq and yoke
Hi Ashraf.
Manhattan here! I am modifying 737 trim wheels to function with forward motion for nose down, and backward motion for nose up. The movement will only be a couple of inches either way, and will internally push against a micro switch. This is far from authentic, but at least the wheels will be operable.
The real wheels turn 47 times in either direction to go from fully nose down to fully nose up!!
Just a thought.

Re: home made tq and yoke
Hi Tony, 47 time! WOW .. nah I would love to get 1 rotation for pitch up and another for pitch down. btw .. do I need to write a program code to get the throttle to work proper?
Im so distracted with all these questions .. thanks so much for your help.

Re: home made tq and yoke
Hi
Throttles normally work with the use of potentiometers (variable resistance devices). A throttle lever is attached to the potentiometer (commonly referred to as a volume control) and lever movement alters the resistance which affects the engine. You can connect the potentiometer to one of Leo Bodners modules which plugs in to a usb socket.
You can operate the trim wheel a larger rotation if you place the micro switches further apart so that you push the wheel forward or backward the distance between the up/down micro switches.
Normally, the wheels are operated electronically, and can be seen spinning on some real flight video's.
Good luck.
TONY.

Hi Ashraf
There is a way to connect trim wheels by using the mechanics of a mouse-
if you take apart a computer mouse and use the wheel inside the mouse you
Can assign the wheel through flight sim for the trim wheel movement
Easy and cheap to do ,just connect the small mouse wheel to knex cog

Some people have used multi turn pots, so the wheels can turn many times and the adjustment is more precise. The pots are attached to a board like Leo Bodnars and interfaced via FSUIPC.
The actual build will depend on the TQ design you use.
Hope that helps.

Hi Dave.
Is a mouse wheel a bit too sensitive for any gearing to be attached? Not sure how this works?

A mouse wheel is normally attached inside to a small wheel with small slots cuts in it. This rotates between a photo sensor and receiver that counts the pulses created when the transmitted light passes through the slots in the wheel. Other companies use slightly different methods but similar in function.
As with potentiometers, you can calibrate these to suit the application. For example in FSUIPC it doesn't really matter what pot you use because you can calibrate the range it has within the interface.

Hello again.
I understand how pulses are transmitted via the slotted wheel inside the mouse housing, but cant see how the mouse is connected to the PC, or what physical action (surely not the scroll wheel on the mouse/) is used by the pilot to actuate trim settings? Somehow, there has to be interaction between the trim wheels and the mouse wheel for the pulses to be counted and read in FSUIPC? Can you explain what the physical set-up would be for the hardware involved - eg mouse and trim wheels?
Thanks for the help that You are giving - it is much appreciated by those looking for authentic cockpits.
Tony.
Re: home made tq and yoke
Hi Tony
open the computer mouse in 2 halfs
and remove the electrics with mouse wheel and attached USB ccable all you have to do is figure out in your home made tq how connect the mouse wheel
to your trim wheel
when the trim wheel is moved it moves the mouse wheel and through the USB connection into you fs computer where you can alter the feel and settings in fsuipc there is no input output card needed

Many thanks Dave.
Cant help mentioning that when living in Perth, I visited St Andrews many times and would love to live there - but costly!
