I haven't been posting anything in ages - and about as long have I been pretty busy with other stuff but now I finally had the time and peace to continue working on the flight instruments integration. Here's a little video of the progress.

I still have to iron out a few minor issues but basically it's working, so I hope, I can go to the next gauge soon, which would probably be altimeter.

Still need to to the hardware design for the interface board - which is not my strong side...

That's cool is it a real one or something made for a flight sim??

That's a sim gauge from Flight Illusion. That's the whole point of my project, to make sim gauges available for GCS building, so the user can start without having to skim eBay to find some surplus real gauges, take them apart, construct new mechanics and electronics for them, etc.

And I prefer those "steam gauges" over EFIS because "steam gauges" are readable in ANY weather and lighting conditions, while EFIS, for example on laptops or tablets, are really a problem in bright sunlight.

From my experience, FI makes not only the cheapest (relative...) sim gauges but their mechanics are also the most sophisticated, making the gauges - among other things - super flat... Perfect for Peli case lids.

Really nice with the artificial horizon and the Imu Stefan, I looked at these a few years ago for flight sim but they were and are a bit costly for that.

However an artificial horizon by itself along with a few LED readouts could give you enough info to save your plane.

It looks to me like you've basically got the most important one working.

Best Regards,

Jeps, just a few details to iron out. I have to find the ideal refresh rate on which the gauge doesn't throw updates away and doesn't start stuttering but otherwise it works.

The MAVLink bridge and the library to control the gauges are separate projects on my Github. Piece after piece I plan to support all FI gauges and the lib will make it easy with comfort functions like setRoll(degree) or setPitch(degree).

That's a great project.

Sir......I would love to learn more about your instruments.  I have the perfect application for them but I don't know enough to do it myself.


Please feel free to contact me if it is something you would like to share.  I am very interested

Brett, I have set up a project page at http://stefan.gofferje.net/uav/arduillusion

There's a short description of the project, links to the current code and a roadmap. I'm very much at the beginning but the code is under heavy development. There is also a small chance that a bog manufacturer might start producing the hardware interface but I guess, that depends also a lot on the resonance to my posts here on DIYD.

Thank you for your reply and link.  I really like what you are doing.  This is exactly what I would need to finish up my Cockpit Ground Station.  

If your interested this is a link to my blog on FPVLAB http://fpvlab.com/forums/showthread.php?16769-Full-Cockpit-Ground-S...

and here is one of several videos from my youtube channel on it. https://www.youtube.com/watch?v=Q_AKDyhpLrg

I think you could agree that this is exactly what I need and I am very excited to follow your progress.  I think my ground station would be the perfect show case for your system!  Thank You for your work in its development.
