Just a quick note to everyone who has been waiting - I finally have the the project Beta-launched. This means the web site is up and active, and the code is on Github. I am also working on an experimental aircraft to begin flight testing, but that is probably a year out or more.

Hello Don,
i'm Alfred from France, very nice work, I also build an EFIS based arduino, I would like to know if your EFIS is functional.
By cons I do not have a 3D printer ...



I am fairly functional. See the "known issues" on the github page. You can find links on the main project page www.theopencockpit.org.


Hi .i just found your project . it looks very good and must build for my myself . Just wondering if your any nearer posting on your website ? I dont want to order the screen until the code ready to try . Keep up the good work ...cheers darren

Super impressive. I'm going to make one of these for my homebuilts (RV-4, Silent-IN, HP-18) and try it out. Awesome idea! I want to see the build and BOM. I'm building two SoftRF with pitot/static for my gliders. It will use XCSoar running on a tablet. I'd love an PFD if I get into the clouds.


No comment on your design, really - I don't fly, but I might "borrow" it for another Mega+display project I need for my printer enclosure - but if you have any links to opencockpit.org, please ask the webmaster to clean up their site. Firefox refuses to connect because of an invalid (incorrect domain) security certificate.

Thanks. I have been on chat with tech support for a couple of hours before discovering why google says the SSL is bad. The site is now on, but but still pretty much a placeholder. I am working through posting the code for the project on github next, and then will work on uploading documentation to the web site. BTW, this project (and case) uses a somewhat expensive but VERY nice display shield: http://www.newhavendisplay.com/nhd43ctpshieldn-p-9520.html. In aircraft projects, the display is critical - and this is the best one I've found.
