I have 8 instruments. They were in a ast-300 simulator. Y tried to get the whole cokcpit, but finally only could get the instruments:
-Airspeed
-Artificial Horizon
-Altimeter
-Turn coordinator
-HSI
-VSI
-Vor with GS
-RMI
My first idea is to make a Lancair (like prepar3d realair) cockpit.
But instruments scales is perfect for cessna 172 or piper cherokee. So I must think about it.
Im trying to interface them with prepar3d. Some of them are easy (d'Arsonvals.. pots..). Im using Arduino Mega, link2fs, fsuipc..
Im new in all this stuff and it takes time and work.
Here it is a vid testing VSI and Altimeter.
VSI is only a d'Arsonval.
Altimeter has a DC motor to move the gauges. Needle position is read with a precision ten turn potentiometer. Kollsman is read with another pot.

Altimeter works well. But only reads 10.000 ft bacause the reading is made with a 10 turn pot.
10.000 is not enough. Is it?
So Im thinking in put some gears to convert it to 20.000ft. And perhaps a crosshatch flag..?!
The most difficult one is going to be the HSI. It is a real one bendix king HSI.
Im having problems with some synchro resolvers. Im looking for info but it seems to be difficult to operate them.
I think Im going to change them for absolute encoders. Could you recommend me a good and cheap absolute encoder?
Thanks!
