Ok, a person capable of writing real code should give this a try. In the mean time here is my feeble attempt to hack this out of some VB.Net code samples.

The idea was to sync and overlay flight data with recorded video of the flight. Unfortunatly, it is a PITA to get working the way I have it now


export FDR file
manually edit out everything but Alt, Speed, Temp, Throttle, and RPM.
Also make best guess to get data synced within 1 minute of recorded video.
Kick of my POS program, load data, load video, use slider to adjust data to match observed flight.


Its a kludge, but I'm finding it to be a rather nice tool so far. Here's a link to a youtube video I made. One down side is, I can't figure out how to save the output, so I had to resort to hand holding a camera pointed at my computer screen. I felt like the blonde with the monitor on top of the photo copier... :censored:

Hey, sounds like a fun project. I do the same but in real-time.

My solution was a bit more costly but mostly plug-and-play. An AVT 3170 Video scaler/blue screen mixer. :eek: I basicly drag a video studio around with me so I made a custom one that fits in two aluminum cases.

It displays the Eagletree data using transparent overlay on the video stream and outputs the mixed image to my Head Mounted Tracker/display.

Test of video feed from ME-262 cockpit (http://home.comcast.net/~darkfool/video/262Vid_Dash_test_03.wmv).


Eagletree is supposed to offering a OSD module real soon. I can't wait.

Ok, that is cool, especially being able to see it in real time. How are you getting the data from the in-flight eagle tree to the computer for re-display via the head mounted screen?

I'm using the Eagletree 900Mhz. data tx. and Wireless Dashboard. The data tx has two power settings. Low for limited range, say rc car track or indoor use and high longer range operation. The Wireless dashboard connects via the usual USB connection and works essentially as a data receiver for the Eagletree software. You can then use the same "Live Mode" as if you have a direct connection to the Data Recorder on your bench.

I won't even get into the GPS aspect. Check their website. I have a professional account with Google Earth that I use for live-link data from the Eagletree system. It gets pretty weird from there on.....internet viewing of realtime data remotely on Google Earth, real-time remote control of cameras, etc.

Have a good one,
