DIY helmet cam video with speed and HR data from Litpro

Yep, we use the metric system so it's only 38 mph on lip, 34 mph on air, casing it 29 mph and back at gas with 44 mph. We used it a lot at EMX150 series this year and lap time was in 0,5 sec compared to transponder timing. The LitPro is connected via bluetooth to Polar H7 heart rate monitor strap.

This is how it looked from outside (actually this was end of training session, so he was going a little bit faster).

The main thing in LitPro is that it captures lap times and segments (as you mark those on the iPad app), but you can also see the lines (and compare those on your other laps), speed, G-forces and by using external HR belt also the heart rate. The app is evolving all the time, so after each upgrade there is some new cool stuff added.

I just mirrored the iPad screen on my Apple laptop and captured it using quicktime player (no need to buy anything). Then in Final Cut Pro just put those on top. Easy, but not too cool looking. I actually asked LitPro to enable a view without the google map at background, so hopefully it comes out soon so it won't look this dumb.

For us the app that is made for motocros, the ease of use (just one button) and accuracy have been the reason to choose this over watch.

1.) What's the value of having g data?
In "session analytic" we are usually comparing different lines to see which one is fastest through each part of the track. But also we make notes when testing some settings / modifications on bike or have rider try different technique (riding on bigger gear etc) and using the app. it's easier to see did it have any effect? The "Gate Drops" mode is really useful when working on starts as it automatically knows when you are doing starts and puts those on one group for easier analytics. We used it in the end of this season combined with slow-motion video to find really good set-up (gate preparation, throttle position, where and sit on bike, where to change for next gear ect.) for Emil.

2.) When you turn on the litpro, does it auto capture laps for as long as you ride?
Yes.

3.) Can you map a full gopro video with litpro data overlaid?
Yes, but it as each lap separated in the app, you would need to laid each lap individually on the video.

4.) Doesn't a cycling device like a Garmin do most of this already with the exception of measuring g's? And again, what's the real value of g data?
We have found this really easy to use and because it's made for motocross it seems to fit our needs. We are not really in that level that we could use G-forces other than that when I cross rutted on jump face and hit the tree, it was around 9 G's In the future I would guess that using it to analyze how the suspension is working (lower G's while going the braking bumps).

5.) The process you mention only captures a screen shot ?
No, you hook up the iPad to mac with your charging cable, then in quicktime player you choose the "new movie" and next to "rec" button choose input video for iPad. Then you can record all the action happening on your iPad.

6.) When comparing laps, can you compare more than just 2 consective laps? For example, can I visually see each lap and time to understand which line gave the best lap time?
The app shows automatically which laps were the fastest and also in which segment. Then you choose one lap from the list you want to study and in map view the app gives automatically 4 of your fastest laps to compare plus a lap called "Lap99". Lap99 is ideal lap that is made by combining you best segment times.

Yep, but that would be DUI, not DIU Had to edit the subject line anyways.

Now Tonynz is only one of us who knows exactly how 12.9 G crash feels like and has data to prove it
