I finally got to use the Waylens and the lap-timer feature at two back-to-back Track Night in America events. The video footage looks great (minus my swiveling mount issues), but the lap timer data overlays have some issues. In one session the GPS conked-out (and eventually the video too), which I believe was due to a tenuous connection to the mount. On my camera, at least, I have to push the camera quite firmly onto the mount to make sure both sides of the connection click in.
I double-checked the connection the second night and didn’t have these problems and was able to capture all of the footage. However I found that all of the videos had some kind of issue with the lap timer data. Most sessions had 6-10 full laps around the course, but at most only three laps were recognized by the lap timer. Oddly, you can still hear the chime when I cross the start/finish line on subsequent laps, even though the times aren’t reflected in the final composited video.
Another odd behavior was in my last session when it was recorded as one single 21-minute lap despite ten trips around the track. Too bad, this had my best laps! I’m pretty sure I went through the same flow each time to setup the lap timer prior to leaving the grid.
I’m not quite sure what the issue is, but I’m passing this along to the Waylens folks to let them know the Lap Timer feature is really cool, but I had some stability issues. I still have all of the original files on the SD cards so I’m happy to share whatever data is needed to help with debugging. This is not intended as a whine-fest, but as honest feedback and an opportunity to improve the product.
