Attached to the Throttle Console, the control is done again with the IOCARDS system. In the picture, connected to the paralell port is the Master Circuit, and, vertically mounted 2 OFF Displays Control Circuit boards. For more info, visit : http://www.opencockpits.com/

Basically, I followed the same steps as per the EFIS/MCP

Rear view of the front panel: as you can see, with so many wires I decided to implement plugs, because welding is more easy, and correcting any mistake too. There are totally 38 displays, 9 rotatory switches, and 3 switches.

As concentric encoders, I have used rotatory switches, self-made in concentric form, according the design of Pedro Bibiloni. You can find tutorials about all this again in http://www.opencockpits.com/

The displays circuit boards are clamped to the panel by mean of small plywood pieces

Ready for closing the assembly. For making easier the wiring, the fixed "1" and the "." are wired through the vertical bar in the picture. Arriving are 5 volts: as outputs  there are one 470 ohms resistor to each fixed segment (showed with different colours for each function display)

Assembly view: in the future it will grew up with a CDU (by now just thinking)

Runing: see how nice are the concentric rotatory switches

Now I need less clicking the mouse!!!!!
