Where do you start building your home cockpit? Right: Probably with a FCU - as long as you are an Airbus-Driver. After couple of hours of research, reading and testing it was clear: The only way to build it properly is with mobiflight and the corresponding PCBs provided on Github. Have I ever ordered a PCB? Yes. Once. Have I ever soldered components on a PCB? No.
And I am sure there are many people outside in the same situation. With this Thread I want to document my personal process, hope for answers to questions
that might come up and at this end should result in a detailed complete guide in HOW TO BUILD YOUR MOBIFLIGHT FCU
Step 1: THE PCB
As I am not a big fan of a big bunch of cables, I decided to go with the FCU PCB Design provided by Mobiflight on Github
Everything you need is the file called PCB_A320_FCU.json
After downloading the file, you should be able to open the file in EasyEDA. After that, the only thing you need to do is to click FILE -> Generate PCB Fabrication File.
And thats it! Now head over to the website of your choice (I would highly recommend JLCPC
, upload the ZIP-File and order the PCB. I have ordered 5 PCBS, as this is the minimum amount of PCBs and payed 28€ including shipping to Germany. Only 9 days later the PCBs arrived.
Step 2: 3D Printing first prototypes
As I was full of excitement, I downloaded the first 3D-Printing-Files. And I was curious how the Push-Pull-Encoder will be done! And wow, this solution is smart! It Consists of a 3D-Printed Frame and Slider, where the Encoder has room to slide back and forwards and the Push & Pull Event will be triggered by two tactile switches!
As I still had a bunch of tactile switched laying around, I printed the first prototype. The documentation recommended 6x6x16mm tactile switches. But I had 6x6x10mm switches laying around. So I edited the slider a bit and have a wonderfull working Push-Pull-Encoder! (If you are interested in the customized Slider-STL, let me know!)
TO BE CONTINUED
I read through the BOM and saw all the needed components.
- Does somebody from Germany have a hint, where to get the parts for a nice price? Amazon is not often the perfect choice. For example for resistors. I used to have a Conrad in Hometown. But they are gone. What about Reichelt?
- LED-Driver: Max7219 are the only ones being supported, right? I saw 10 pieces for 15€ from China - is that an ok price?
