I recently bought the Racebox Mini after seeing the news posting about full compatibility with RaceChrono Pro.
I submitted a ticket asking about the IMU and RaceChrono Pro mentioned they don't use the IMU yet, but it's something they are working on.
I also saw the post from @aol
about the IMU not looking good.
My question is:
The only reason for buying the Racebox Mini is for the lean angle measurements.
Should I return the RaceBox if the IMU is bad?
I don't know much about the RaceBox's own app, but it's obviously their responsibility to meet and deliver what they advertise, but that's off topic for this forum.
I'll try to get it to work, and if I still can't get it working after another track day I'll send it back.
If I do magically get the native app to record anything at all, can this data be imported into RaceChrono Pro?
It would be good to override the Phone's GPS data with the RaceBox's post-session if possible.
Thank you for looking into this.
Really helpful. I'll try it out at the next trackday both ways around (record in your app, and then in theirs for import to yours), and see what works.
The RaceBox Mini app still isn't working, it doesn't seem like the developers are doing anything to rectify the situation.
My only hope is that RaceChrono are able to pull the IMU data at some point, and I can use that.
@aol_of_RaceChrono if I do get their app to at least log a session and export it, which option in your app do I select for import? There is no .VBO option on my app. Would I just select "RaceChrono"?
We already have working "release candidate" of our IMU stuff, just needs little bit more works on the other parts of the app.
@aol_of_RaceChrono you are a true gent. Thanks.
I have a trackday at Silverstone later this month. I'll try to grab some data.
Is there anything else I can grab for you on the day to help with testing? Including your IMU work?
I'd be I tempted to see how your IMU data grab will work for a phone that is, for example, not in a perfectly level position. Motorcyclists will need to cram their phones in the tail; would it then need to calibrated to 0 before heading out?
It might even need a delayed button press, as access to the screen will be limited once the phone is in place in the tail and the bike is picked up off the kickstand.
Also turn on the "Internal sensors" in RaceChrono settings, so both IMU's will be recorded. I can then compare the data between the IMUs. It doesn't matter if the phone is inside your racing suit, as it's one of the possible use cases anyways... But crammed in the tail is better
You can have the RaceBox at any position, just make sure it does not move during the session, and please record a section of data where the bike is at standstill and not running, so we can calibrate the gyro data.
Any data you record and send to me, will also go toward testing the new IMU feature, so it will be very helpful.
At this point lean angle, acceleration and others - are they read from Racebox or from the phone? For me it looked really smooth/high resolution, and pretty precise. So my assumption was that it's from the Racebox already.
if you import a gopro video with gps is the lean angle still gps or is it gopro IMU?
I have been very happy with just gopro to record track sessions. no worries about phone holding and 18hz gps is nice.
Oh I think I see what you mean. Would sharing this file help? From a hero8
Sorry for resurrecting an old thread. However, did @aol_of_RaceChrono update the app with real lean angle from RaceBox mini?
I appreciate you are busy.
Trackday season starting soon! 😂
