I have been playing with Nav/Com modules for a pedestal for a while and have managed to get prototypes working in XPlane 11 as a proof of concept. Given I had some spare time this afternoon I thought I'd try and get them into a more modular form.
First I started off with a printed faceplate:
Next I printed a spacer block to go behind it:
Into the spacer block I put 2 x TM1637 White 6 Digit 7 Segment LED modules.
I then superglued the spacer block to the faceplate:
I am using a dual axis rotary encoder for this as well as two push button switches:

Next it was time to start the wiring. Please note, I am no master of soldering or wiring!
Then it was time to add the back circuit board layer:
This photo shows how compact the module can be by the use of the TM1637's:
I've downed tools for the night but have got to this point. I still have to wire the rotary encoder and switch on the circuit board, as well as print some buttons to make contact with the two switches. For the TFR switch I will make a button that has a back on it that will fit between the two TM1637 circuit boards and make contact with the switch. Then I will make a ribbon cable to allow this to be connected to the Arduino Mega.
Now that I've worked out how to do this one I'll be able to get onto the Com and ADF panels as well. Will post a pic of the working unit once I've finished it.
