Next instrument done

At the moment it looks like I’m on a run 🙂 – but the RWR (Radar Warning Receiver) is designed similar to the eHSI so I decided to build it right now, since I already had the display laying around for quite some monthes now.

3D printed parts on one picture with mounted encoder.
Like the eHSI the top consists of a front and a backplate that get bolted together and sandwich the display and frontglass inbetween.
This time I made a small design change, the backplate is not the same size as the front but a bit smaller, so it slides inside the front.
Now the gap I had at the eHSI between the 2 plates is totally gone.

Displayboard- and connector mount get screwed to the backplate like I did with the eHSI.

The front glass has been produced on my little CNC mill.
First the markings got engraved with a 60° engraver, aftewards everything was cut with a 2mm cutter.
Finally the engravings got filled with white acyrlic paint.

All parts before final assembly, with both variants of the rotary knob I printed.
The display is 2.8inches with a resolution of 480×480 pixel.

Everything connected.

I was quite eager to test both instruments – it’s a great feeling seeing the data from the sim coming to life.
