I’m sure you have already checked out some prices for home cockpit parts of manufacturers. Well, I felt the same when I saw them for the first time. That’s why I’m going to show you the possibilities and best practises of DIY in a home cockpit project, so you can build your own one.

 

The Airbus Instrument Panels

If you take a look at the airbus instrument panels, you will quickly see that new replica parts seem to be very expensive at the first

view. But if you carefully calculate the costs for acrylic glass, engraving, paint, switches and buttons, the korrys, backlighting, wiring, electronic interfacing (so you only have to connect the USB-cable from your PC) and wage – things look a bit different.

Nevertheless, there is still money to save. How much depends on the complexity of the individual part. I would clearly not recommend to make yourself a FCU for example, except you are very talented in soldering and electronics in general and you have much time left. The MCDU on the other hand, can be a better suited part for a DIY-Activity.

Selfmade Speed Brake Control

Many of the instrument panels are engraved with text, which is intended to be backlighted later. If you want your panels to look at least fairly like the original ones (what I highly recommend) you should either buy the panels from a manufacturer or you should have access to a CNC machine.
If you buy the panels without switches, buttons and interfacing they will also be much cheaper than buying them as plug and play version. At this point you should definitly not save on the wrong things because the panels get you the look and feel of a real airbus 🙂

The picture on the right shows my self made Speed Brake Control. The panel and the knob were purchased from a home cockpit parts manufacturer. This is a well suited part to test out your DIY-skills 🙂

 

Korrys

Now what is that? The Korrys are those small rectangular pushbuttons, that can be found on nearly every instrument panel in the cockpit. Those small parts are quite hard to replicate, if you want to be them as original as possible. Most of them consist of two separate chambers with differently coloured LEDs in it. Here are some challenges that are lying ahead:

  • The Korrys need to fit into your panels
  • The Travelling distance of the pushbutton should be at least 2mm to be fairly original
  • Cutting and applying the printed translucent covers
  • Soldering the small LEDs and PINs, optimally onto a circuit board

There are some good approaches on making own Korrys on the Internet, here are three of them, for example:

I will try the Hispapanels-Option like Michael described shortly and report about it.

 

Switches and Buttons

When it comes to switches and buttons, there are more options to do things yourself. Of course you need to buy the switches and buttons that fit into your panels, too. If you want them to look like the original ones, they will be more expensive than just customary ones that you can get in any online electronic shop. That is a question of your ambitions on realism.

When you have bought your switches and buttons you need to wire them and connect them to your interface card.

 

Interfacing

Interfacing is probably the most complex part of your home cockpit. Now what does this? Imagine, you’ve got a mechanical switch or button which you want to use to turn on the Fasten-Seatbelts Sign in your home cockpit. Somehow that signal has to be transferred to the simulator. So first of all, you need an Interface Card. Those cards usually consist about an USB-Connection and lots of Pins, where you can connect your switches and buttons.

The cards are offered by many manufacturers in different versions, here only a few for example:

  • Arcaze (Simple Solutions)
  • Arduino
  • Chinese Manufacturers via Ebay
  • Leo Bodnar
  • Opencockpits

After you’ve connected your interface card to your computer, it will be recognized as a Joystick. Then wire the switch or button with your interface card with a port of your choice. Depending on the quality of your card, you can define an Input in your card’s software and set some parameters. So you are telling your card to listen on a certain port for a signal to transfer it to your computer.

After you have done that, launch your FMGS-Software, for example Jeehell FMGS. In the Configuration-Program you can assign a predefined action to your switch/button push event, like “Turn on Seatbelt-Signs”. And that’s it! In this way you can wire your complete home cockpit. We are going to take a closer look on Interfacing in a future post, after you got started with Jeehell FMGS.

 

Backlighting

Backlighting is a topic that I really underrated for a long time in my home cockpit project. You have to consider, that If you want to build a closed shell – and/or you want to use Beamers instead of TVs for the projection system, you won’t have much brightness in your cockpit. For this reason and because of the general ambitions to realism, backlighted instrument panels are more than just “nice to have”.

You can realize backlighting by 12V amber-coloured LED-stripes that you can cut according to your needs. We will take a closer look on this topic in a future post regarding electrics and power supply of your home cockpit, too.

 

Cockpit Structure (Shell)

When it comes to the cockpit shell, the main stand, the sidebases or your pedestal – it’s DIY time! You can make most of those parts from wood and cut them with a conventional jigsaw. But a bench saw with a feeding can help a lot.

If you now have probably access to a carpentry with professional machines, too – this is your home run! I’ve seen fantastic results from homecockpit builders that have access to professional machines. Otherwise don’t despair – you will learn and get better with every piece, as I did!

Take a look at my self made side window. It’s made from five millimeter medium density board. The only tools I used were my jigsaw and a compressed air tacker.

Warning: If you are not familiar with the tools mentioned above, be careful and get yourself assistance from an experienced friend or neighbour when you are insecure at the beginning. Some DIY-markets offer free regular trainings for multiple specializations. Maybe so in your city?

 

List of Tools

When you’re about to start with DIY, here’s a inital list of tools and things you might need:

  • Cordless Screwdriver with two battery packs and a set of good drills for wood and metal
  • Jigsaw with sawblades for wood and metal
  • Clamps
  • Tongs
  • Hammer
  • Ruler
  • Protractor
  • Hot Glue Gun
  • Abrasive Paper

Hey!

first of all thank you so much for this amazing Blog – this is realy helpfull!

I would like to know where I can find the measurements for the cockpit structure as I would like to let a carpentry do this work!

Thank you in advance and please keep going on – this is fantastic
!

Best regards Andrea Daniel
