Someone asked me to make a thread as I showed some picture of my own planned trim wheel quadrant.
So, here it is.
First of all, i'm not a nerd. I can't write C++ or any other pc-language.
Also I have no idea of higher electronical circuits. So what I do here is just buying parts, solder them and building a case.
For those who want to know how much this costs, I will give lower in this thread a list of parts and there prices.
Since I have already 2 Saitek throttle quadrants, I played with the thought of buying the "Saitek Cessna Trim Wheel". But the price of 50€ for only one axis trim? No way!
Then I remembered that I had upgraded my Thrustmaster Attack Throttle from 15-Pin-Connector to USB, some years ago.
So this little project was born.
Now to the important part. How should its look like, what's the planned size?!
As I mentioned before, I have 2 throttle quadrants. So it would be nice if I can make the whole thing compatible and fitting to it.
The size was then clear.
Height: 11cm
Length: 18cm
Depth: 9cm
Then I decided what I want to have on it.
3-axes for elevator, aileron and rudder!
So I made a list of parts, pices and sizes of what is needed. (for more info just click on the link)
1x A/D USB converter:
Joywarrior-modul JW24MOD-A8-16 14,75€
16 diodes for the button-wiring: 1,12€
3x 10-turn potis:
Poti 3600° 100KOhm = 3 x 12,45€
buttons and switches: depends on what you want ( in my case 4 buttons, 6 double-switches = 32€ )
one alu-plate: 25cm x 50cm x 1,5mm: 10€
USB-cable: I will use an old one.
So in the end 100€.
Now I started designing it with the help of 3D Sudio Max ( damn, i'm not good at it ), to determine the other parts and the layout.
Because of the modul I used had 2 vairants, I made 2 models as seen below.
8 Button Layout

16 Button Layout

The trim wheels have in both cases a diameter of 10cm and a width of 1cm.
the radius of the front plate should be around 5cm.
As you can see from the list above, I decided in the end for the 16 button-solution.
So after my nightshift and 6 hours of work, this is the in between result.

What's missing now are the sides, one stripe of alu for the last poti, the holes for the trim wheels, the trim wheels itself (not yet decided which material or design), solding and painting.
Unfortunatly I have tomorrow no time for further action.
